Why does my android phone turn on and off. Why does the phone turn off by itself? possible causes and solutions to the problem

It is impossible to imagine the life of a modern person without a mobile phone. Despite the abundance of means for communication and communication, this little helper is still in the first place. The phone has become like an extension of the hand, and its absence causes discomfort and uncertainty - what if someone calls or writes while the owner has lost his vigilance? Some especially fanatical users even move around the apartment with the device - it is in the kitchen, in the bathroom, and under the pillow. One can only guess what disappointment befell the owner if phone turned off and won't turn on. What are the reasons for such trouble? But what if we are talking about a brand new smartphone? Don't panic -

Do no harm!

Attempts to immediately disassemble the phone and check "what's inside it" can be disastrous for a fragile device. Without special knowledge, it is pointless to understand the structure of microcircuits and incomprehensible details - at best, these attempts will not help in any way, at worst, they will lead to serious breakdowns, the repair of which can be very expensive, if not unpromising. It will be the worst if phone stopped turning on, for example, due to the fact that the battery is completely discharged. Before taking drastic measures, you need to try to rehabilitate the disconnected phone, but for this you need to find out a number of reasons that can cause the device to malfunction.

Battery check

Situation one: phone can't turn on, although quite recently it worked properly, and the battery charge level was sufficient for at least another day. The simplest explanation is that the load on the battery is too high, especially for new modern smartphones. Their functionality is so diverse that to call such a device a phone does not turn the tongue - rather, a mini-computer. For example, always-on Wi-Fi or Bluetooth consumes too much energy - the phone is constantly searching, trying to catch every network that appears or find a phone with active Bluetooth in order to immediately inform the owner about it. It is enough just to disable these options and use them only as needed (“What to do if the phone runs out of power quickly” can be read on). A discharged battery will cause phone turns on and off after a moment, or even does not react at all to attempts to "revive" him. Eliminating the cause is elementary - you just need to charge the phone, and after half an hour you can use it. Sometimes there are situations when the device has to be left on charge for almost a day, and only after that make a decision to contact a specialist. The fact is that the battery life is usually no more than two to two and a half years, after which it should be replaced with a new one.

Charger

If a phone is dead and won't turn on after trying to charge it, you need to carefully inspect the charger - it may have a damaged wire or a contact coming off. The problem may also lie in the socket of the phone itself, which could break or become unusable from too much use - most new phones have only one hole for all functions - charging, connecting to a computer, listening to music with headphones. How to check it? A win-win option is to try to charge the battery with a universal frog battery. If the phone then started working normally, you can consider the cause eliminated and go to the store for a new charger.

Sometimes it happens that phone charging indicator blinking directly when trying to recharge it. That is, at the moment when the device is connected to the network, it continues to discharge. Experts explain this anomaly by severe overheating, as a result of which the battery does not receive energy. The second option is to use a “foreign” charger, especially if it is a low-quality device, the use of which can be detrimental to the phone. There are cases when expensive smartphones failed after a short circuit in a cheap charger. After such experiments, it will not be possible to do without a hard reset or flashing the phone.

On/Off button

Another reason that phone flashes and does not turn on, may be in a faulty on / off button. There may be several reasons for this. In the case when the phone is completely new and hardly used, the fault lies entirely with the manufacturer - most likely, this is a factory defect. There are two options for solving the problem: either the store will replace the phone with a working one, or the service center will repair the device free of charge. Older push-button phones are usually reliable and strong as a rock, but they also have button malfunctions, and a problem with the power button will most likely lead to a lack of response to the entire keyboard as a whole. There are several explanations for this - in the case when phone dropped and won't turn on, the keyboard may have moved away from the impact. Very often there is a failure in the operation of the buttons, if moisture got in and the phone does not turn on- the influence of the liquid is always detrimental to any technique. However, most often the buttons cease to obey due to the venerable age of the device. In any of these situations, an appeal to the master is inevitable - only he can figure out what actions to take:

• Completely replace the keyboard membrane.
• Restore mounting soldering.
• Replace keyboard controller.
• Perform a complete cleaning of the device and eliminate moisture.

Oddly enough, the most common flash drive can cause phone started freezing. We are talking about a memory card that is inserted into the device to increase its memory. The fact is that most often a flash card is not sold complete with a phone, and the consumer is forced to purchase it separately. It turns out that some memory cards may not be compatible with certain models of phones and smartphones. The recommendation in this case is simple - you need to buy a flash drive only in trusted stores of well-known brands. By inserting the card into the device, you can immediately check it - if phone freezes or does not see it, you can safely return the purchase. If the smartphone does not want to accept any of the proposed flash drives, most likely the problem is in it. In this case, it is recommended to contact the service center - it is quite possible that you will have to flash the phone, after which it will start functioning smoothly with any memory cards.

Installing updates

The situation when phone won't turn on after update, happens infrequently, but still sometimes happens, especially with new smartphones that have constant access to the Internet. Various updates come to the phone, the installation of which may be unsafe for the device. Problems usually start immediately after installing updates - the phone can turn off on its own, then turn on.

Sometimes screen does not turn on, and if it is lit, then incomprehensible inscriptions like “Windows phone” appear on it. The process of switching off / on can be continuously repeated several times, while no intervention helps to stop the malfunction of the device. In this case, you can try to turn off the phone by removing the battery from it, then insert it back and turn it on again, and then use the factory reset, which differs for each model. If everything is done correctly and the failure is not very serious, then the phone will reset and reboot itself. This process may take some time, after which the device will return to its previous state and start working as before.

If the installed updates have seriously damaged the phone, you will most likely have to use * - only a hard reset can restore the system to factory settings, while all the information saved on the SIM card and memory card will remain intact, but the system information will be completely cleared. Contacts, SMS and all programs installed in the phone will disappear. But in this case, you have to choose the lesser of two evils - returning the phone to working condition will cost much less than buying a new expensive device.

*In order to do this, you need to select the brand of your phone in the "Hard Reset" menu on the left and then find your model or use the search on the site (top menu).

Mechanical damage

Despite the convincing claims of manufacturers that their brainchildren “do not burn in fire, do not sink in water and never break”, situations when phone won't turn on after being dropped occur very often. Breakdown can occur at the most unexpected moment. For example, a smartphone stowed in the back pocket of jeans is in danger - crouching unsuccessfully, the owner can easily crush the screen. Repair in this case is inevitable. And the cases when Phone dropped and won't turn on, the most common, specialists of service centers can tell about this.

Very often there is no visible damage to the phone, but all attempts to turn it on are useless. You can try to rehabilitate the device by opening the lid and reinstalling the SIM card, USB flash drive and battery - perhaps the contact just came off from the impact. No effect? So, the damage is more serious than it seemed at first. It remains only to contact the master, who can restore the original state of the phone. You may need a flashing for this, but you should not be afraid - the device will function no worse, if not better, than before.

What to do if the phone turns off by itself? For starters, stop panicking as this is just an Android smartphone. If it stops working correctly, then you need to delve into either the software or hardware component.

Please note that old devices 5-7 years old begin to fail due to the impressive service life for the device. Remember that the gadget, in principle, is not designed to operate for more than 2-3 years, it becomes morally and physically obsolete, wears out and ceases to adequately respond to what is happening. Software is harder to find, the OS is no longer updated, and the characteristics do not allow most programs to run correctly.

Neither the top nor the budget gadget is immune from obsolescence of components. A modern device from the same Chinese manufacturer will give a significant head start to the flagships of 2011-2012, for which you paid a tidy sum.

Reasons why Android turns itself off

Why does my phone turn off by itself? It is dead and you put it on charge. In theory, after 15-20 minutes the device should start, but either this does not happen, or it goes into a cyclic reboot. It is not uncommon for a smartphone to turn itself off several times a day, while in standby mode, or during work / calls / games. There are enough reasons, so let's analyze the key ones:

• non-working power button;
• the battery has served its purpose;
• contacts are oxidized;
• a software failure has occurred;
• application conflict;
• mechanical damage;
• prolonged use;
• freezing.

Power key not working

The reason lies in the closure of contacts. If the device is under warranty, but the start key is extremely unstable, and you either need to press hard on it or press it repeatedly, exchange your smartphone for a new one, or take it to a free service prophylaxis. The reason is a factory marriage. In older phones, the problem occurs due to "advanced" age. Each button has its own work-to-fail resource. Yours has obviously reached its limit. Contacts moved away, oxidation began, dust got in.

Recovery will not be cheap, because often you will be offered to change not only the membrane, but also the controller, diluting the procedure with mounting soldering. Often, the amount of restoration is not much different from the price tag for a new state employee.

Battery

What to do if the phone turns off by itself, but the charge is full? The battery is probably out of date. To get started, try the following: leave it to charge for a day. If nothing happens, then there are several development options:

• the charger burned out;
• problem with the memory connection slot;
• the battery has served its purpose;

The first and third options are checked very simply: change the used component to a new one. True, on some smartphones the battery may be non-removable. In this case, a trip to the SC is provided. The same thing awaits you if the charging socket is either gouged, or clogged with dust, or oxidized. Only diagnostics will show the final verdict.

Contact oxidation

If you used the gadget with extreme caution and care, you are still not immune from oxidation of the contact base of the motherboard and other elements. Moisture can enter through the environment, sudden changes in temperature as condensation, and even from carrying the phone frequently in the summer. The palms sweat, sweat seeps into the seams between the lid and the speaker/microphone opening. The concentration is minimal, but the oxidation process is a long process.

First of all, clean the contact pad on the battery. If it is perfect in appearance, it does not interfere with walking on it with a sharp object, but very carefully. This is followed by drying with a hair dryer at minimum power so that the air flow does not spoil the internal parts. Putting the gadget on the battery is strongly not recommended - the device is simply not designed to work at such a temperature.

In the most critical cases, it is worth going to the master.

Software

The phone turns off by itself. Android is an open platform, so you can download any applications from both Google Play and external resources on it. Some get carried away excessively and do not understand that programs have begun to simply conflict with the file system, causing a constant reboot. Here, only the complete demolition of data, memory re-partitioning and flashing the gadget saves. Resetting to factory settings rarely helps.

If you do not know how to reflash the device - and do not think about doing it. In inept hands, it easily turns into a "brick" without the possibility of recovery.

In the future, you should not download several editors, players, galleries for viewing photos, and especially GPS navigators. No more than 1 representative from each direction. Exceptions are games.

Mechanical damage

The most common cause of sudden reboots is the fall, bumps and “flights” of your gadget. There is one way to check the device after such an impact - try to bend it a little. If the device turns off, then we can judge the internal problems fraught with a visit to the SC. The second point is a strong heating of the back cover, if this has not happened before. Perhaps the thermal pad between the chip and the cover has come off. Details can be found only after the analysis.

Just in case, check all wireless modules for serviceability and shake the gadget a little. If something rumbles - carry it in for repair.

Moral obsolescence

The smartphone works properly from 3 to 5 years without cosmetic and major repairs, if you use it carefully. Techniques on Android began to be published since 2008, which means that the oldest one is now about 9 years old. Also look carefully at the OS version: it must be at least 4.4.4, since earlier versions are not supported by either software developers or firmware manufacturers. This is a morally obsolete product that is just as expensive as memory. To get on such a spare part is a serious problem even in large cities. Repairs will cost more than the cost of modern gadgets.

Working in the cold

Often, smartphones work very poorly in the cold, the capacitive type display suffers especially. It reacts to heat, so it often does not perceive touch with fingers - hands have to be systematically warmed in pockets or gloves. Read the user manual carefully. Many devices automatically turn off at -20 degrees and this is completely normal. It is better to carry them in the inner pocket of your clothes, not in your purse and in the pocket of your pants and jeans.

Spontaneous shutdown of the smartphone is a common problem that gadget owners regularly face. There are quite a few reasons why the phone suddenly turns off by itself. In this article, we will analyze the most popular of them.

When the phone turns off by itself, it creates some discomfort and interferes with normal operation and communication. Most often, this situation is faced by owners of old equipment, but in some cases, problems can also occur with new devices.

If this is a one-time issue, don't panic. The reason why Android turns off may be a banal failure in the system. But, if it is regular, the gadget is recommended to be taken to a service center.

However, some tasks can be dealt with at home. Full instructions for problems of different origins can be found below.

Power key not working

Mechanical malfunctions of the power button often cause the phone to turn itself off.

It is impossible to replace the key yourself at home. If this situation happened with a new gadget, there is a factory defect. When contacting the warranty service, the equipment will either be repaired or replaced with a new one.

But sometimes the breakage of the power button is preceded by bumps and falls. Modern smartphones are quite fragile, and even a slight impact on the ground can lead to malfunctions and malfunctions. The solution is the same - contacting the service center to replace the power off key.

You can also diagnose a malfunction at home. It is necessary to simultaneously hold down several combinations (for example, the volume rocker and mute) and look at the result. If it does not respond properly, then repair is needed.

Software failure

Another option - the most rosy for most owners of equipment - is a failure in the operating system. Errors in its operation may cause the cell phone to “hang” when performing a certain task and the inability to turn it off (or reboot) in the standard way. You can try to manually remove the battery and turn it on again. However, this method should not be abused.

Battery

If the phone constantly turns itself off, does not hold a charge and slowly charges, there is only one way out - to put another battery.

Of course, you can extend the life of an old battery for a few days by controlling the background and downloading a few special programs, but the battery will not fix it.

Moreover, a swollen or mechanically damaged battery can be life-threatening. There have been cases where a defective battery caught fire simply in the hands of users, or near their faces, causing severe burns.

Therefore, you should not delay with the replacement of the battery. This will not only affect the comfort and performance of the device, but also protect you from health risks.

Contact oxidation

Even those who carefully and carefully handle their smartphones are not immune from another type of mechanical damage - oxidation of contacts on the motherboard.

Moisture can get on contacts and junctions in the following ways:

• With a sharp change in temperature (condensate is released).
• Frequent carrying of equipment in hands in hot weather.
• Getting caught in the rain.
• Fall into a container of water.
• Other.

Modern top models are already equipped with moisture resistance, but so far there is no such function in budget cellular phones. Moisture enters the phone through connectors, seams and speakers, becoming a catalyst for oxidative processes.

As in the previous cases, this problem cannot be dealt with manually, and it is recommended that the phone be repaired by the masters.

Removing excess from the system

Android is positioned as an open platform, so each user can personalize it to suit their tastes and needs. Most often this happens by downloading software from the Play Market.

Sometimes these are several applications, and sometimes their number reaches such proportions that the equipment simply cannot cope with the processor load, and constantly turns off.

The solution in this case would be:

1. Check the authenticity of the operating system. Only installing a licensed Android OS ensures that the smartphone will normally cope with the tasks.
2. Clear the storage of unnecessary programs. Optimal loading - up to 15 different applications.
3. Check if the installed utility conflicts with the OS. You can find out on the forums, or in the reviews directly under the program page in the Play Market.

Screen breakage

Sometimes a broken screen is mistakenly perceived as a cellular failure to turn on. It is provoked by malfunctions in the gland, which, as a rule, are preceded by falls or contact of the device with water.

On most gadgets, the reboot is accompanied by a slight vibration response, which can be felt even if the screen does not show signs of life. It is worth checking for a response, if not, take it to the master.

Mechanical damage

Different types of “flights” are a real disaster for fragile devices. In most cases, they are brought to the service after the fall.

You can check the malfunction yourself by slightly bending the smartphone in your hands. If it turns off, then repair cannot be avoided.

If, after the impact, the back cover in the area of ​​\u200b\u200bthe camera or battery began to warm up, then most likely the root of the problem lies in the lagging of the thermal pad. It is possible to give final conclusions only after parsing the gadget.

Moral obsolescence

The average service life of a cell phone is 3-5 years, provided there are no breakdowns and careful treatment. But many people use them for much longer, so over time they have to visit repair points more often.

Equipment needs to be regularly changed and updated, because even now it is problematic to get spare parts for devices that were released 5-6 years ago. And some malfunctions of outdated models refuse to be repaired at all.

Therefore, when buying, pay attention to the OS version - if it is below 4.4, then the service will be in question.

Working in the cold

Gadgets are not recommended to be exposed to temperature fluctuations - this affects the battery. When working in the cold, many devices refuse to work and turn off on their own - this is normal practice. The range of suitable temperatures is indicated in the User's Manual.

Memory card

If, when installing a memory card, the smartphone does not work well, is buggy or turns off completely, it must be removed and replaced with another one.

Consider the reasons why MicroSD may conflict with the OS:

• Speed ​​class incompatibility.
• Factory marriage in the memory card.
• Mechanical damage to the slot that slows down its operation.

Conclusion

Regardless of the source of the problem, it is not recommended to repair the smartphone yourself, especially if it is under warranty. Proper repairs, which will not adversely affect further work, can only be carried out in a service center.

When asked why the Samsung phone turns off by itself, the masters of our service center will answer without any problems. This behavior of a Samsung phone is usually caused by the following reasons:

1. Problems with the battery.

After some moisture or for other reasons, the contacts of the battery (or the phone itself) may be contaminated. Elementary cleaning is the solution to this problem! Battery contacts can also be bent, which leads to poor power contact, and therefore, to the self-shutdown of the mobile device.

In addition, the battery itself (loss of battery capacity) can cause this behavior of the smartphone. Or, from time to time, she "swollen", which can be seen with the naked eye. In these cases, battery replacement is required.

2. Moisture getting under the case.

This is the classic reason. The impact of water (aggressive environment) quite often leads to our service center customers whose phones have been bathed in liquid. Our masters will eliminate the results of moisture inside the device and repair your device.

3. Depreciation of the "upper" cable.

As a rule, the Samsung phone turns itself off when there is an incoming call. Due to the wear of the “upper” loop during the operation of the mobile device, a short circuit occurs in the power circuit, which leads to similar consequences. Replacing the worn part will resolve the situation.

4. Faulty flash memory or processor.

If your Samsung phone is dropped from a height or hit on a hard surface, the flash memory or processor may be damaged. Due to the fall, their contacts could move away from the system board, which causes violations of such a plan.

5. Malfunction of the display module (for Samsung phones of the slider format).

The display module is a cable that connects the system board and the phone's display. Over time, this component may fray, and then it needs to be replaced.

If your Samsung phone turns off by itself, just come to our service center. Smart Center specialists will not only conduct a high-quality diagnostic examination, which, by the way, is always free within the walls of our workshop, but will also perform the necessary repair of a Samsung phone, which will return your gadget to its previous performance.

At the same time, the phone becomes very hot, for what reason can this phenomenon be!)?

Good afternoon!

Hello.
The problem started yesterday. At first, all applications crashed, something like "Application Gallery has stopped." Then it started to turn off. I'm just looking at the screen, and the phone is off. Just a black screen, no shutdown signs.
Now it either works or it doesn't. It turns off, sometimes it turns on again (if you're lucky), sometimes it's stupid.

Good afternoon!
Most likely, a software failure, the cost of recovery is 1000 rubles, with data loss.

Now let's look at the reasons why Android turns off by itself and try to fix the problem. Some reasons can be eliminated on your own, and with some you will have to contact the service center, because. you will need special equipment to fix the breakdown.

This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Again, it is worth mentioning that the phone / tablet can turn off during a call, game, just in your pocket and other situations. Every situation has its own reason.

Android shuts down due to firmware or installed programs

The most common case and quite easily solved.

As you know, Android is modified by each smartphone manufacturer for a specific model. As a result of mass character, there are flaws in the firmware.

Also, applications from Google Play are not always of good quality, or one of their updates.

This problem is solved like this:

Android turns off while playing

There are not only games here, but also other resource-intensive applications that load the phone: long viewing of YouTube or a video in the player, various programs with a graphics load, and more.

Did you notice that the phone gets quite hot? As a result, protection can be triggered that turns off the phone and prevents it from breaking due to thermal causes.

Try to search the web for information about your phone model and find out if it is characterized by such strong heating under load, or is this an isolated case. There is a possibility that you will have to contact the service.

In addition, prolonged heating may cause incorrect power supply from the battery to the device modules, resulting in a malfunction that causes overheating. But we'll talk about the battery a little later.

Android turns off during a call

In this situation, the reasons are most often the following:

• Damaged modem module (cellular sensor). This can happen both as a result of natural wear and tear (you have been using the phone for many years), and as a result of physical damage (shock, fall, moisture, etc.). In this case, only the replacement of the module in the service center will help. It will be difficult to diagnose such a breakdown on your own, because. all other options must be ruled out.
• The problem is with the battery. During a call, the battery incorrectly starts to "distribute" energy to the phone's modules, resulting in a failure and the phone turns off. The best way to check is to put in a similar battery.
• Software errors of the phone firmware itself or installed applications (if the call occurs on Viber, Skype, Telegram and other instant messengers with a voice call function). What to do was considered at the beginning of the article.

The battery as the reason for the arbitrary shutdown of Android

Most often, it is the battery that is the reason why your phone turns off by itself.

Let's not dwell on cases where you have a non-original battery installed or it has worn out for more than 2 years. Consider a situation where the phone is fairly new (less than 2 years old) and the battery is factory installed.

Above, I already touched on the situation when the battery incorrectly distributes energy to the smartphone modules and a failure occurs that causes a shutdown.

If access to the battery is simple (just removed the back cover), then visually assess the condition of the battery: are there swelling, signs of corrosion, or the presence of dents, cracks.

But, in practice, I had to deal with such a situation.

A phone from the "sale of cheap models in a communication store" segment. Those. some not very expensive models, designed for the mass consumer and going on sale.

As it turned out, the battery did not fit snugly against the contact group on the smartphone, as a result of which, when typing or shaking, the contact moved away and the phone turned off without an influx of energy.

OK. This is not your case and a phone from a well-known company, but a flagship model.

There is an option that is not charging with the original cable. As a result, the charging and power controller fails, which disrupts the power circuit. Recently, manufacturers have been specifically doing such things so that the user uses only original accessories (the pioneer of Apple) / You can only diagnose this at a service center.

Or does your phone turn off in the cold? Batteries don't like to stay in a cold negative environment for a long time, so keep it in your pocket, close to your body. Also in this case, it will be discharged a little faster.
