Why is my phone restarting itself? Samsung Galaxy reboots by itself - Solutions. When connected to a computer

There are times when owners of Lenovo phones face the problem of spontaneous rebooting while taking pictures, talking, launching all kinds of applications, etc. Why is this happening? Let's try to figure it out.

The most popular reasons

The device may reboot on its own for a number of reasons. The most common among them are:

• Software failures.
• All kinds of damage due to external physical impact (cause may be a fall or a strong blow).
• There is moisture under the phone case.
• Failed battery.
• PCB damage.

What to do?

In order to normalize the operation of your device, you should take a number of actions that directly depend on the nature of the breakdown.

Reboot at power on

In cases where the phone itself reboots during power-up, you should restore the factory settings. Often, in this way, the operability of the device is completely restored. Each model has its own reset method.

Permanent reboot

A similar reaction can be traced in cases of a damaged battery. In order to check this, you should get the battery itself, put it on a hard plane and twist it. If the battery spins without any problems, then you need to replace it.

During telephone conversations

In cases where the device reboots during an incoming call, or during a conversation, you should contact the service center. The reason may be the loss of contact between the battery and the battery. You can also solder the connecting contacts yourself, but without the proper skills, this is quite risky.

When photographing

It's not uncommon for the phone to reboot by itself when you turn on the camera. Such a breakdown is usually caused by a malicious program - a virus. You can get rid of it with an antivirus.

If your device rebooted itself, but you managed to find out why this is happening and solve the problem, write it down in the comments. This information will be useful to other users.

Reading time: 4 min

Let's look at the main reasons why the Android phone reboots by itself: what causes this and how this or that problem is fixed.

Interestingly, both Chinese “NoName” brands and famous flagships like Samsung Galaxy, HTC One, or Sony Xperia are affected by the deficiency. Let's understand the reasons.

Mechanical damage

Let's start with the leader of all troubles - falls. This also includes blows, negligent use, use of a smartphone for other purposes (opening bottles, hammering nails, etc.). Kind of funny, but they happen all over the place. The phone is designed for calls and work, but not for such events. Yes, there are shock-resistant models produced by companies like CAT, but they are few and far between.

Methods of "treatment" are banal to disgrace: buy a cover, bumper and protective glass. Protection is flimsy, but periodically saves. This will save you from damage to the motherboard, processor blade, memory, camera module and vital cables. But it's still worth going to the service to understand exactly the reason for the reboots.

Firmware and all about them

Often heard from friends about "firmware"? In short, this is the replacement of the “native” smartphone OS with a more recent version, or a modified one. There are 3 options:

• official;
• custom;
• test.

If the native firmware of the device starts to slow down (too many applications, have not been updated for a long time, viruses, residual cache files), then you can reset the settings to the factory settings - it should help in 90% of cases. It is also worth looking on the Internet which version of Android is relevant for the smartphone at the moment. The update process happens on its own without your intervention, so no skills are required.

Custom ones are more difficult. The only stable foreign firmware can be considered exclusively Cyanogen Mod, but this team broke up, and the remnants of the team renamed themselves Lineage OS. Their work was really worthy, but had one significant drawback: the firmware was installed at your own peril and risk. Also be prepared for reboots, CPU overheating, unstable battery, GPS, modem and other key components that affect stability.

As for the test ones, which are laid out in abundance on resources like w3bsit3-dns.com, XDA and analogues. If you are going to use your smartphone as a "guinea pig" and know about the problems in advance - install it. The rest is categorically not recommended to do such things without knowledge of the materiel. This is the easiest way to turn the device into a "brick", not to mention the cyclic reboots.

Battery

The battery, like any storage device, is designed for a certain number of charge / discharge cycles. If you constantly charge the device, then sooner or later the battery will simply lose its full potential and will not hold a charge. A similar drawback is typical for Li-Pol models with a "memory effect". Ying must be charged to 100%, and then discharged to 0. Only after that you can put it on charge. Li-Ion drives are devoid of such a flaw.

Critical moment: you need to use only the "native" charger. The point is the current strength indicated on the charge. If the manufacturer indicated, for example, 1A (Amp), then the value cannot be exceeded. Therefore, you should not use more powerful analogues of 1.5-2A, since you can “kill” the battery much faster. She's just pissed off. The average cycle with proper operation is limited to 1.5-2 years. In the future, the battery begins to lose its properties.

Another factor is contact oxidation. If moisture has accumulated inside the device, then this may be the reason for the reboot. If the battery is removable, remove it, dry the smartphone, wipe all contact pads with alcohol as carefully as possible and insert the drive after 30-60 minutes. A swollen one must be replaced.

Motherboard defects and factory defects

This category is the most unstable due to the fact that there are many reasons for the breakdown of contacts, loops and other elements, only a complete analysis and verification of each component individually will help here. Often, a defect is caused by a fall, “curiosity” (opening a smartphone to see how everything works there and subsequent inaccurate assembly), moisture, dust, and more.

Less common is a factory defect, which affects no more than 1-2 gadgets per 100,000 devices. The manufacturer often indicates this himself. Also look at thematic forums, look for a topic with your model and see the characteristic "sores". If you didn’t drop, drown or open the device, and it reboots, then something is short inside. It is better to send such a smartphone under warranty. You will lose time, but you will get a workable analogue.

Memory problems

Installing a large number of applications is highly discouraged due to the conflict of certain files with each other. This is especially true for programs for working with the camera, GPS, data, antiviruses and "cleaners". Each has its own algorithm of work, so reboots are not uncommon.

Despite the stability, “glitches” periodically appear in the operation of many Android-based mobile devices. One of these bugs is a hard reboot of Android. This material will help you figure out why this happens and what to do in this case.

Why does the phone constantly reboot itself, what should I do if the device cannot start after rebooting?

Consider the main reasons why this can happen:

• mechanical damage to the device has occurred, usually due to its fall or impact;
• occurrence of failures in the software;
• failure or problems in the operation of the battery;
• the reason may be of a hardware nature if there are malfunctions in the operation of the printed circuit board;
• moisture on the mobile device can also provoke a forced reboot of the smartphone.

In practice, users often face the problem of restarting their smartphone as a result of a breakdown in the signal power amplifier or battery. This leads to an increase in energy consumption, due to which the system resorts to an emergency reboot of the smartphone. Failed components can be replaced, it does not take much time and money.

The reason may be the appearance of failures in the operation of the platform itself. Programs and utilities installed in the memory of a mobile device may conflict with each other. Sometimes the reason lies in the installation of applications that do not match the version of the installed operating system.

Actions in case of spontaneous hard reset

The problem of cyclic reboot is familiar to many users. The following are effective ways to solve the problem.

All time

As we reported, the cyclic reboot of the device may be associated with a damaged battery. In order to verify this, you need to remove the protective cover and remove the battery from the phone. Place the battery on a flat, hard surface, then rotate it. If the battery spins quickly and easily, this indicates that there is a bulge on its case or the battery is starting to swell. Replace the battery with a new one, since the batteries cannot be repaired.

If the battery is working properly, then try updating the firmware of the mobile device, as well as all the programs installed in the device's memory. To do this, go to the official Play Market store and select all available updates. You can click on the update all applications button, this will allow you to update everything at once, but it is better to view all updates, rather than delete applications that are not used. When programs and applications are updated, the platform itself needs to be updated. If there are no changes, contact the specialists, since the problem may be software in nature.

At the moment of switching on

If there is an endless reboot of the mobile device when it is turned on, then first of all, you should reset the configuration to the factory settings. In most cases, this method solves the problem. The procedure for restoring factory settings is individual for each smartphone, detailed instructions are indicated in the service manual.

Alternatively, you can try to remove the battery and reinstall it after half an hour. Often the reason lies in an overheated smartphone, but there may be a problem with the activation buttons getting stuck. If these methods did not solve the problem, then you should flash the device. Flashing is performed independently or with the involvement of specialists (the video was filmed and published by the NTS Setup channel).

During a conversation

If the reboot is carried out when you are talking on the phone or when it receives an incoming call, then it is possible that the battery is losing contact with the device at that moment. When used for a long time, a small gap may appear on the back of the battery, namely the gap between the connecting components. Intensive operation of the device leads to shaking of the case, and this contributes to the separation of the contacts.

To diagnose this problem, try shaking your smartphone several times, this will determine the cause. If the device automatically reboots when shaking, this indicates the need to re-solder the connecting components. If the smartphone is no longer under warranty, then it must be sent in for repair. If the cause of the failures is a software error, then there are several ways to solve the problem:

• return the phone to factory settings;
• update the version of the operating system and application;
• seek help from specialists if the above two methods do not help.

After update

If you have updated your mobile device, but after that the phone still reboots, then try the following:

1. Turn off your mobile device and remove the battery from it.
2. Wait about 15-20 minutes.
3. Replace the battery and reactivate the phone.

If the device still reboots, then keep track of what updates you put on the phone. Sometimes applications automatically block the optimal operation of the smartphone, in some cases programs may conflict with each other. If the phone was working fine before you updated it, then revert back to the factory configuration and reboot the device.

The problem may also lie in the installation of malware or virus applications, in the absence of an antivirus, this can happen along with updating the phone. You can solve the problem by following the above steps to restore the factory settings. If this does not help, then the smartphone must be reflashed.

When you turn on any app or feature

cameras

If the mobile device reboots when the camera is activated, then the reason may lie in the fact that one of the applications has caught a virus. Install an antivirus program on your smartphone, determine the cause of the problem and restart the device. If there are no changes, return the device to the factory configuration, if necessary, before performing this task, back up files - photos, contacts, documents, etc. If the reason lies in the operation of the camera itself, mechanical damage to the device, then it is necessary to disassemble the phone and look for a malfunction. Often the camera does not work correctly due to the fall of the phone, the cable inside the gadget could move away, you can install it yourself (the author of the video is the Pavel Sak channel).

Try formatting the memory card or replacing it with a new one. If the problem is not mechanical, then usually the reboot is due to a malfunction of the memory drive. If your phone has been dropped in water, it's entirely possible - turn off your phone, remove the battery, and wait for it to dry.

GPS

If you restart your phone while activating the GPS function, you must do the following:

1. Check how your mobile device works with a new SIM card. The problem with many modern smartphones is that they do not function well with old SIM cards.
2. If the reason lies in the damage to the board associated with the fall of the mobile device, then specialists can solve this problem. Better take your phone to a service center.
3. Try changing the memory card and check how the device works with the new drive.
4. Revert your smartphone to factory settings.

Bluetooth

The problem of rebooting the device when the Bluetooth module is turned on is more relevant for owners of NTS mobile devices. To get rid of the malfunction, reflash your mobile gadget. In principle, you can not use this function at all, but this is not an option. Before flashing, try to restore the factory settings, but not the fact that this will help (the author of the video is the channel HELP IN CELL REPAIR).

If you want to turn off Bluetooth, then this will not be easy. As a result of the fact that the user has a few seconds to disconnect due to a reboot, you need to act quickly. Turn off the smartphone and remove the SIM card from it, as well as the memory drive, this will make the device work faster. This will give you about ten seconds to disable the feature.

When launching applications

This problem is more relevant for Nokia phones. The search for the cause and its elimination is carried out as follows:

1. Turn off the phone with the button.
2. Open the back cover of the phone and remove the battery from it.
3. Check if the battery is working.
4. Wait about 15 minutes, then replace the battery.
5. Turn on the phone, then run the application again, upon entering which the smartphone rebooted.
6. If the problem persists, then you need to reflash the device.

To avoid this problem, try not to use registry cleaner applications. Also, do not install very large programs on your smartphone and, in general, use only official software (the video was shot by the Master Android channel).

When connected to a PC

The appearance of a problem when connecting to a computer may be due to malicious software. Run diagnostics on your mobile device for viruses, if this does not help, reset the configuration to factory settings or flash the device. In the absence of results, it is necessary to seek help from specialists.

As for the scheduled reboot, in order to ensure the normal operation of the smartphone, it is necessary to diagnose the date of the latest updates. We are talking about both programs and the operating system. If you are the owner of a Samsung phone, then try starting safe mode on your phone. If the phone does not restart after that, this indicates that the problem lies in the operation of one of the programs. Install an application on your phone to clean up excess software, it should find the cause of the problem.

In the article we will consider the reasons why the android itself reboots, their solutions. Let's take simple actions, which in some cases can save you from going to a service center, which means saving time and money. This breakdown is typical for famous and unknown brands, as well as old phones. Reasons for a spontaneous Android reboot can sometimes be fixed at home, but some can only be dealt with at a service center if the phone or tablet can still be saved.

Smartphone battery related reasons:

1. Weak battery contact or oxidation;
2. The battery does not properly distribute signals to modules;
3. Swollen or otherwise mechanically damaged battery;
4. Damaged power charging controller due to the use of a non-original or cheap charger;
5. The battery has served its purpose;
6. Low quality non-original battery;
7. Moisture, dirt getting under the body.

Only changing the battery to another will help, since they are not being repaired.

Other technical reasons:

• Signal power accelerator failure;
• Power button drop;
• Damage to the main or printed circuit board, other spare parts (after getting wet, falling).

Software reasons:

1. The presence of applications that conflict with each other;
2. Firmware problems (especially relevant if a custom, inappropriate, beta version of the OS is manually installed or a release has occurred recently);
3. Smartphone overheating;
4. Virus on the device.

That's why the phone itself restarts android.

What to do if your Android phone keeps restarting. Application issues

Do you have several antiviruses, cleaners, camera applications, GPS? Possible conflict of algorithms. Therefore, you should not install too many programs, especially if you are not sure that you need them. Start in safe mode. If the reboots stop, remove the extra application. Check your device for viruses. Have you noticed overheating and a long reaction of the smartphone? Perhaps you downloaded something from unverified sources. More specifically, the presence of a virus is indicated by a reboot of the phone when an application (for example, a camera) is launched. The highest quality antiviruses for android: Norton Security & Antivirus, Sophos Antivirus & Security, Bitdefender Mobile Security & Antivirus, Antiy AVL, Cheetah CM Security. No malware? Do you have a lot of "heavy" applications that often work at the same time, and are you already tired of notifications about the lack of memory? Try clearing the cache of programs ("Settings" - "Applications" - any application from the list - "Clear Cache"), remove unnecessary ones. You can use one of the cleaning programs: Clean Master (if there is an antivirus, it may conflict), DU Speed ​​Booster & Cleaner, GO Speed.

If you suspect an OS malfunction

If you think that there is nothing suspicious and new in your files, and the previous tips did not help, reset the settings to factory settings, after saving important data on an external drive (a flash drive is suitable), reset the settings to factory settings. The advice is suitable when it was not possible to determine the problematic software on your own or there is a suspicion of damage to system files. Section "Settings" - "System" - "About phone" - "Software update". Why is the phone constantly rebooting by itself android? Perhaps there are problems in the firmware. To update it, go to "Settings" - "About device" - "System updates" - click "Check now". Agree to the software update. The smartphone will reboot itself after the operation is completed. If there are no updates, look for information about your smartphone model along with the Android version. Perhaps the problem is in the firmware. You will have to wait until they fix it or find to install an unofficial version if you are sure of your actions. Reboot while turning on the bluetooth. Change your phone firmware. If it reboots too quickly for that, pull out the SIM card and memory card to make the device work faster. Turn on your phone and quickly turn off bluetooth. If the device reboots, then you will not encounter this again. If necessary and desired, you can install a third-party file transfer application.

Actions in case of physical damage to the device

In case of technical damage, most likely, you need to contact a service center for help. There are some things you can try to do on your own. There may be a problem with the memory card. Take it out and perform the action that usually triggers a reboot. If this does not happen, format the memory card. Did not help? Replace with a new one if possible. Remove the battery and wait 30 minutes. This will help against overheating, which could be the cause of reboots. The phone keeps rebooting Android when shaken. In this case, the battery loses contact with the contacts. This can happen if the phone is used frequently. You need to solder the contacts. Of course, it is better to do this in the service, but you can do it yourself. Soldering is a rather delicate process that should be considered separately. Notice the dirt on the battery terminals? Remove the battery, wipe the connections with cotton wool soaked in contact cleaner or spray. Slightly straighten the contacts for a tighter connection with the battery terminals. Phone reboots after turning on GPS and can't start? There are several solutions. Replace the SIM card if it is much older than the smartphone.

The case may be in the memory card or the settings that need to be rolled back to the factory settings.

Samsung phone reboots itself. In addition to Android, Samsung smartphones were released running Windows Phone. In the former, the problem of spontaneous reboots is more common. Solutions, as in the previous paragraphs. To roll back the firmware, if necessary, visit the official website of the manufacturer: http://samsung-updates.com/device/
