The phone started to go off. Samsung smartphone turns itself off and on

It is impossible to imagine the life of a modern person without a mobile phone. Despite the abundance of communication and communication tools, this little assistant still comes first. 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 particularly 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 befalls the owner if The phone turned off and won't turn on. What are the reasons for such trouble? What to do if we are talking about a brand new smartphone? There is no need to panic -

Do no harm!

Attempts to immediately disassemble the phone and check “what’s inside” can be disastrous for the fragile device. Without special knowledge, it is pointless to understand the structure of microcircuits and incomprehensible parts - at best, these attempts will not help in any way, at worst, they will lead to serious damage, the repair of which can be very expensive, or even futile. It will be most offensive if the 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 a disconnected phone, but to do this you need to find out a number of reasons that could cause the device to malfunction.

Battery check

Situation one: I can't turn on the phone, although quite recently it was working 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 it’s hard to call such a device a telephone – rather, a mini-computer. For example, always-on Wi-Fi or Bluetooth consumes too much energy - the phone is in constant search, trying to catch every network that appears or find a phone with active Bluetooth in order to immediately inform the owner about it. You just need to disable these options and use them only as needed (“What to do if your phone runs out of battery quickly” can be read at). A discharged battery causes phone turns on and off after a moment, or even does not respond at all to attempts to “revive” him. Eliminating the cause is simple - you just need to charge the phone, and after half an hour you can use it. Sometimes situations arise when the device has to be left on charge for almost a day, and only after that make a decision about contacting 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 The phone is dead and won't turn on After trying to charge it, you need to carefully inspect the charger - perhaps its wire is damaged or the contact is coming off. The problem may also lie in the socket of the phone itself, which could break or become unusable from too frequent use - most new phones have only one hole for all functions - charging, connecting to a computer, listening to music with headphones. How can I check this? A safe option is to try to charge the battery using a universal frog battery. If the phone starts working normally after this, 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, while 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 known 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 The phone blinks and does not turn on, may be a faulty on/off button. There may be several reasons for this. In the case where the phone is completely new and has hardly been used, the blame falls entirely on the shoulders of 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. Old push-button phones are usually reliable and solid as a rock, but they also have problems with the buttons, and a problem with the power button will most likely result in the entire keyboard not responding. There are several explanations for this - in the case when The phone fell and won't turn on, the keyboard could move away from the impact. Very often the buttons malfunction if moisture has entered and the phone does not turn on– the influence of liquid always has a detrimental effect on any equipment. However, most often the buttons stop working due to the advanced age of the device. In any of these situations, turning to a specialist is inevitable - only he can figure out what actions need to be taken:

• Completely replace the keyboard membrane.
• Restore assembly soldering.
• Replace the keyboard controller.
• Completely clean the device and remove any trapped moisture.

Oddly enough, the most ordinary flash drive can cause the phone started to freeze. This is a memory card that is inserted into the device to increase its memory. The fact is that most often the flash card is not sold complete with the 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. After 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 lies with it. In this case, it is recommended to contact a service center - it is quite possible that you will have to reflash the phone, after which it will begin to function smoothly with any memory cards.

Installing updates

The situation when phone won't turn on after update, does not happen often, but it still happens sometimes, especially with new smartphones that have constant access to the Internet. The phone receives various updates, the installation of which may be unsafe for the device. Problems usually begin immediately after installing updates - the phone may turn off on its own, then turn on.

Sometimes the screen does not turn on, and if it is on, then strange inscriptions like “Windows phone” appear on it. The process of turning off/on can be continuously repeated several times, while no intervention helps stop the malfunction of the device. In this case, you can try to turn off the phone by removing the battery, then insert it back and turn it on again, and then use a reset, which differs for each model. If everything is done correctly and the failure is not very serious, the phone will reset and reboot on its own. 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 seriously damaged the phone, you will most likely have to use * - only a hard reboot can restore the system to factory settings, while all information stored on the SIM card and memory card will remain intact, but the system information will be completely cleared. Contacts, SMS and all programs installed on 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 site search (top menu).

Mechanical damage

Despite the convincing statements of manufacturers that their creations “do not burn in fire, do not drown in water and never break,” situations where phone won't turn on after falling, happen very often. A breakdown can happen at the most unexpected moment. For example, a smartphone placed in the back pocket of jeans is in danger - if it sits poorly, the owner can easily crush the screen. Repair in this case is inevitable. And the cases when The phone fell and won't turn on, the most common, service center specialists can tell you 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 cover and reinstalling the SIM card, flash drive and battery - perhaps the contact simply came off due to the impact. No effect? This means that the breakdown is more serious than it seemed at first. All that remains is to contact a technician who can restore the phone to its original condition. This may require flashing, but don’t be afraid - the device will function no worse, or even better, than before.

No matter how hard you try to protect your smartphone from falls and breakages, there is no insurance against the fact that it will one day turn itself off and then refuse to obey your commands. What to do if the phone turns off by itself?

Why did my phone turn off and I can’t turn it on?

There can be many reasons:

• Power button failure. Sometimes the cause of such problems is a defective power button that needs to be replaced. It may simply wear out, in such a situation it is not always profitable to take the phone to a service center, since the specialist will advise you to carry out other repair procedures; it will be easier to buy a new budget device.

• The battery has failed. If your mobile device turns off on its own, we recommend checking the rate of discharge of its battery. If this process happens too quickly, we recommend replacing the battery and then checking to see if the situation returns to normal.

• The contacts have oxidized. You could pour tea on your phone, get caught in the rain with it, or come in from outside during the winter season - all this leads to the formation of condensation in the device. If you accidentally get your smartphone wet, remove the battery from it and then dry everything thoroughly. If the phone then refuses to turn on, you need to take it to a service center, where repairmen will try to bring the gadget back to life.

• Mechanical damage and wear. The most common reason is the phone falling. Usually, self-shutdown after such an incident indicates serious problems with the device, so we recommend that you avoid disassembling it yourself; you should take it to specialists. If the phone was cheap, we advise you to immediately purchase a new one, since repair work will not cost a small amount.

Shutdown due to software errors

Software failures lead to problems. If mysterious inscriptions appear on the display, and then the phone turns off, then it is better to start flashing it. The task is not difficult, detailed instructions are included on the Internet, so you can do it yourself.

It happens that the phone starts to turn off after installing another application. To overcome this problem, you should get rid of the latest programs. First, try rebooting, if this does not help, uninstall the software, and for those for whom this is not enough, you will have to return to the factory settings. In a situation where nothing helps, you should try updating the firmware.

Take care of your mobile phone, it usually stops turning on due to erroneous actions, accuracy will help to avoid them. Several more possibilities for resuscitating the device are presented in the video.

The fact that the phone is lenovo, nokia, lg, xiaomi, samsung galaxy, sony xperia, meizu, alcatel, zte blade, fly, huawei, dexp, philips, lumia, prestige, htc, micromax, asus, bq, texet and any other constantly , sometimes or periodically it turns off, the problem is not new.

There are several reasons, because the phone can turn off spontaneously in different situations: when turned on, when making a call, when charging, when watching a video, during a call, after a call, when turning on the Internet, in sleep mode, on the screensaver, with the flash, when just making a call , when locking the screen, when taking photographs, in games, when turning on the camera, when you insert a SIM card, when you go online, after replacing the battery, when inserting a flash drive, and all this for no apparent reason.

Moreover, this can happen when fully charged - at 100 percent, 60 percent, 50 percent of the battery, 40, 30 percent, 20 percent of the battery, 15 or 10.

The whole difficulty is that there is no universal recipe for what to do to solve the problem if a charged Android phone suddenly suddenly starts to turn off on its own - an integrated approach is needed here and often you cannot do without a trip to the service.

Let's look at some options on how to keep your phone from turning off. There are three main reasons why a phone turns off spontaneously: battery, software and hardware damage.

The first reason why the phone turns off is hardware faults

Hardware problems most often occur at contact points - the battery, SIM card, keys, and the detachable connection between the screen and the circuit board.

Sometimes this can happen due to overheating of the processor, but then you need a specialist, and we will look at the battery terminals. Oxidation often occurs there.

Especially if there was contact with water - for example, they kept the phone in their pocket and walked in the rain. What can be done? Remove the battery and clean all the battery terminals and connectors on the phone.

Don’t use sandpaper (it will get worse over time), but wrap cotton wool soaked in pure alcohol or contact cleaner (you can buy it in a store) around something.

In addition to cleaning, slightly straighten the clamping contacts so that they are pressed tightly against the battery terminals.

If the battery is non-removable, then there is no need to disassemble the phone - it is soldered there and you can only cause even more damage to the device.

The second reason why the phone turns off immediately after turning it on is errors in the software

A very effective way to solve this problem is to flash the Android manually - not through a standard update.

Only this method will not solve the problem if you have accessed pre-installed applications, the operating system with root access, or deleted system files.

This procedure in most cases fixes the problem where the phone turns off on its own. I won’t describe the process now - you can find it on this site in the android section or through a search.

Other reasons why a mobile phone turns off even though it is charging

If it heats up and turns off, even a new phone or a new battery with a charged battery, then this is most likely a factory defect - there is no point in describing what to do (the new one is under warranty and I don’t recommend fiddling with it).

If it freezes and turns off, then the problem is most often in the flash memory - it needs to be changed (costs an average of $40)

If it glitches and turns off, then the problem may be in the processor - it cannot withstand the load (usually it gets very hot).

Another reason could be a virus - most do not have security features in the form of anti-virus programs, and new viruses can bypass the built-in protection. You can check with a thorough scan. How to check.

The phone turning off can be caused not only by the above factors. One of the worst and most expensive reasons is damage to the board, when there are no options other than replacement.

In conclusion, I’ll just say there are many reasons, like phones: Lenovo, Sony Xperia, Samsung galaxy, Nokia, Sony, Meizu, Xiaomi, Micromax, LGi, Asus Zenfon, fly, DXP, Asus, Lumiya and so on, and if we take the exact name, then as I noticed, the androids most susceptible to this are Maze M3 s, Samsung A3, Lenovo A319, Samsung gt c3520, lg g2, fs518, xiaomi mi 4c, huawei p9, siemens cx 70, huawei cun 129. Good luck.

Many people wonder why the phone turns off by itself. Answering this question is not as simple as it seems. After all, there are many reasons for such behavior. Do not immediately panic if you are faced with this problem. Try to figure out for yourself what the true reasons for this phenomenon are. It is recommended to act by the method of elimination. But what points are worth taking a closer look at? Why does my phone turn off by itself?

Departure

Very often, our current problem appears due to the device’s battery draining. Detecting this phenomenon is not so easy. After all, few people will independently check whether the battery fits well to the mobile phone. Especially if there were no problems with this before.

To eliminate this option, remove the back panel of your mobile phone, then press the battery firmly against the phone. All that remains is to check whether the device will turn off. Yes? Then the reason is clearly something else. No? Now you have found the source of the problem.

Battery

Why does my phone turn off by itself? The next reason for this behavior is nothing more than a battery problem. Its malfunction almost always leads to the fact that the mobile device begins to turn off and on on its own. Don't be surprised by this.

What to do in this case? Think about how long you've had your phone. Have you followed the recommendations for caring for your device's battery? Did you always start charging after the “problem” component was completely discharged? If not, then the reason most likely lies in the battery.

To eliminate this problem, simply replace the faulty component. Usually, after purchasing a new battery, the phone stops turning off spontaneously.

Battery charge

The reasons don't end there. Why does my phone turn off by itself? Check the battery charge. Not the most common case, but one that occurs in practice. It is the low battery charge of the phone that causes the device to turn off.

This situation is quickly resolved. All you need to do is charge your phone and then turn it on. You will notice how the problem disappears by itself. From now on, just keep an eye on your battery charge. Then you won’t have any surprises with your phone. In any case, you will be prepared to disconnect the device.

Viruses

Unless the reasons for such behavior lie in something more serious. Why does my phone turn itself off and on? Under such circumstances, the source of the problem is not always the device’s battery and its malfunction. Everything is much more serious.

The point is that if you notice how the phone turns off and then turns on on its own, it’s time to check the device for viruses. They cause most gadget malfunctions. It is impossible to predict exactly how a phone will react to a particular virus.

To prevent infection, it is recommended to use special anti-virus programs for mobile devices. Or take the gadget to a service center. There they will help you not only check your phone, but also “cure” it if necessary.

Applications

The list of possible reasons for our current problem does not end here. Why does my Nokia or any other phone turn off? If all of the above options do not suit you, then you can think about installed programs and applications. Utilities often cause problems with your phone.

There are several options here. The first is that you have little space left on your mobile. In this case, you just need to make room. Remove a few of the most unnecessary programs or games - and the problem will disappear by itself.

The third is the presence of malware. To correct the situation, you will have to find and eliminate the problematic utility. After this, you won’t have to wonder why the phone turns itself off and on (Samsung, Nokia or some other). After all, the problem will disappear. Its reappearance is possible when the gadget is again cluttered with programs.

System failure

Why does my phone turn off when charging and more? The last common variant of this behavior is failures in the device’s operating system. They happen simply from time to time, from viruses, and from the number of installed programs and applications. But most often, problems in the operating system are the result of incorrect firmware.

In order not to have to figure out how to correct the situation for a long time, you simply need to reflash the gadget. It is not recommended to do this yourself. It is better to take the phone to a service center.

Usually after flashing all problems are eliminated. If even after this nothing helps, it’s time to change your phone. After all, sometimes the reason lies in equipment malfunction. In such a situation, only a complete replacement of the gadget will help. Now it’s clear why the phone turns off by itself. Fixing this problem is not as difficult as it seems. The main thing is to know where to start. By the way, you should think about firmware only after eliminating all of the above reasons.

In the modern world, a telephone is a necessary thing for a person, which contains many necessary functions. Unfortunately, after prolonged use, it begins to live an independent life: it begins to turn off by itself when you receive a call or when you press a button. Unexpectedly turning off your phone is a very unpleasant incident, especially if you need to make a call at the same hour.

To understand the causes of the malfunction, you do not need to immediately run to the service center for the help of specialists.

There are a number of factors that provoke regular shutdowns of your mobile phone, which you yourself can eliminate.

Main reasons

• Mechanical damage. If you notice that the device begins to turn off after an impact or fall, the reason for the shutdown may be damage to the motherboard or other elements of the device. To check the device for damage to the microcircuits, you need to bend it with your hands. Just without fanaticism. If the phone starts to freeze or turn off, it means that the cause of the problem has been found. In this case, you will need to contact the service center employees.

• Software failures. A regular reboot will not help in this situation. You will need to reflash the device. Enter a request for firmware with the model of your device on the Internet in the search bar. You can find a lot of step-by-step instructions on the Internet for flashing the device. If something doesn’t work out for you, contact a specialist. For a certain amount, a software update will be installed on your mobile phone, and the problem will be solved.

on the video why the phone turns off by itself:

• Incompatible applications. Installing new applications can cause your mobile phone to turn off and freeze. If the problems persist after restarting, you will need to perform a hard reboot. In this case, all user information is deleted, and the problem of self-disabling is solved. To do this, you need to enter “menu”, “settings”, “reset settings”, “reset phone settings”. Next, format the device memory and memory card.

• Moisture affects many devices, especially mobile phones. After moisture gets into the equipment, spontaneous shutdown begins. If water gets into your phone, you will need to remove the battery and wipe off the moisture. After this, dry it in a ventilated place. Never dry your mobile phone in hot air! When heated, the microcircuits may be damaged, then nothing can be done except send the phone for repair or throw it away.

• Lack of RAM. When several applications or one resource-intensive application is simultaneously turned on on the device, in this case, an abnormal shutdown is possible. To prevent your phone from turning off, do not leave several applications turned on, or use less resource-intensive ones.

• Operation. Many devices are picky about temperature conditions. Some devices turn off in extreme cold or heat. Sudden changes in temperature and air humidity cannot be ruled out. Please refer to your mobile phone's instruction manual to ensure proper use. In order to protect against subsequent shutdowns, try to adhere to the operating instructions for use.

When the above methods do not bring effective results, there is only one option left - take the mobile phone to a service center. Upon examination, you will be told the reason for the shutdown.
