Android phone reboots itself

Now we will try to figure out the reasons why your Android phone/tablet reboots on its own and we will try to understand how to fix the problem. It can reboot simply by lying on the table, in your pocket, when connected to a charger, during a call, and in other cases.

We will structurally divide the article by types of reasons to make it easier to read and find the item you need.

This article is suitable for all brands that produce phones on Android 10/9/8/7: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Attention! You can ask your question to a specialist at the end of the article.

Battery as a reason for Android reboot

This reason is the most common and can occur in both used and new phones.

Here we should consider both a low-quality battery and poor contact between the battery and the contact group on the phone.

Increase

If the reason is in the battery, then at some point energy may not be supplied to the modules, or it may not be distributed as needed, which leads to an emergency reboot of the device in automatic mode. In this case, the phone may also turn off itself.

During shaking, contact is lost; During a call, energy is not supplied correctly; While playing or using applications, the phone heats up, which causes a lack of energy and so on.

A defective battery means:

Defects in the production of the original battery (remember the case with the Samsung Galaxy Note).
Using a non-original battery of low quality.
Natural wear and tear of the battery over time.
Consequences of moisture getting under the housing.
Signs of oxidation or “bloating” appear.
The consequences of using a non-original charging cable, which damages the charging or power controller, as a result of which the smartphone does not distribute energy correctly and reboots itself in an emergency.

The current problem can be solved by installing a new battery and performing appropriate performance tests.

From practice. One customer's Samsung Android phone rebooted itself when he tried to type something on the on-screen keyboard. The result was tapping on the screen, which contributed to the loss of contact between the battery and the contact group of the phone itself. We managed to calculate it by chance.

Also, if you use a non-original and, especially, cheap cable, the voltage may be supplied incorrectly, which causes the system to fail.

What to do if your Honor or Huawei phone keeps rebooting?

There is no universal solution; it all depends on the individual technical “symptoms” and “behavior” of the device. Let's look at specific situations and solutions.

When starting Android

The phone cannot be turned on, every time the boot window appears it turns off. In this case, the problem is either with the firmware or with the battery. We either put it on charge and try to turn on the device, or we reflash it. If it still starts after being connected to the outlet, then contact a technician. Diagnose the battery or socket.

When you turn on the camera

First, clear the application cache. Then remove unnecessary components from RAM and install an antivirus.

After activating GPS

When you turn on some module that requires more energy consumption, a reboot indicates a lack of RAM.

When Bluetooth is turned on

As already mentioned, Bluetooth consumes quite a lot of energy and takes up additional RAM. If you notice a shutdown when you activate it, clear the memory and make sure the device is charged at least 60%.

During a conversation

During a conversation, the cellular communication module is always activated, and after a long conversation it tends to overheat. Overheating often affects the overall performance of the device. If the phone heats up and turns off, we recommend that you do a full diagnosis at a special service center.

When launching applications

Shutting down when launching applications indicates that the gadget does not have enough power and RAM to activate the program. Either install some old version or free up some space.

Reboots itself after updating firmware/Android OS

Along with the previous problem, firmware is also one of the most common causes.

In this case, you need to independently analyze the situation and remember: an arbitrary reboot of your Android phone or tablet began after updating the firmware or not. There can be either a planned update of the Android version “over the air” or forced installation via a cord.

We will also include this item:

Unsuccessful obtaining Root rights to the phone.
Conflict of installed applications. In this case, try using the phone in Safe Mode for a while and see if problems appear.

Software

The Android operating system and installed applications are a software component. Errors in their operation, especially after updates, cause the phone to shut down, after which the operating system takes a long time to load. Malware also leads to this. In this situation it is necessary:

check your smartphone for viruses;
if a reboot occurs after launching a specific application, it needs to be reinstalled;
If the gadget turns off regardless of the launch of programs, you need to reset the operating system settings to factory settings - this will eliminate all system errors and return to stable factory firmware.

Problems with the flash memory module or the memory is overloaded

As a result of physical damage (shock, moisture, power surge), the flash memory module may fail. As a result, when the phone is loaded, it “falls”, which causes the system to crash. A reboot occurs and the phone works again until a certain point.

The second option is to overload the RAM with installed applications. Many users do not close applications, but simply minimize them using the Home button. As a result, these applications remain running in the background, consuming not only RAM, but also energy (have you noticed that the battery quickly began to drain?). There may also be a loss of performance and slowdown of the phone/tablet. We clean RAM using special programs, or the built-in method.

Causes

Experts highlight a list of the main reasons for frequent “relapse”:

mechanical breakdowns of the case or other parts of the mobile;
interruptions in the OS, errors due to incorrect firmware, as well as application failures;
outdated battery model;
failure of the motherboard, which is associated with the provision of charge;
moisture entering the mobile case and contact oxidation;
the gadget froze due to the low temperature outside;
software problems or system failures.

Malicious applications

Most often, reboots occur due to bad software. It is recommended to remove programs that interfere. Because of them, failures occur. Check that all utilities are reliable and downloaded from official sources. Fake software negatively affects the mobile phone. Remove questionable programs and download applications from the correct platforms.

If the software is active in the background, android will restart. If the problem is related to the software, use the instructions:

Clear your smartphone's memory of unnecessary programs. Go to the “Settings” section, then launch the “Programs” folder, select the one you need and click on the “Delete” button.
Check for updates to all applications. Download new versions via Play Market.

If the situation has not changed, proceed to the following points

Software running in the background

Remove widgets that are active in the background. Check out the list of such programs and get rid of unnecessary ones. There is also an option to freeze files. It is possible to resume the software at any time without re-downloading. At the same time, the widget takes up memory in the smartphone.

Disabled or missing pre-installed apps

If the owner of the Android gradually disables the programs, it is possible to accidentally deactivate the built-in software. Without them, any gadget will stop working, since they are necessary to open the Android operating system. Check the status of the utilities:

launch the “Settings” section and go to the “Applications” folder;
set sorting and view the list of system programs;
re-enable the necessary applications if they were frozen;
reboot

Overheat

Most mobile devices turn off on their own if they overheat. If you use your smartphone during peak summer temperatures, work at high brightness, and turn on all the additional options, the gadget will heat up and turn off on its own. This way the phone saves battery. Device owners are advised not to overload their mobile phones in the summer heat. If this situation occurs constantly, then use technical support services.

Unstable battery position (unstable contact)

This problem occurs on devices with a removable battery. Some Samsung models are overloaded for this reason. Any mechanical damage displaces the battery, the mobile turns off and on. A common scenario is that the back panel is bent and does not secure the battery. Internal contacts become dislodged and wear out. Depending on each individual case, a solution is proposed. It is recommended to use tape and glue the back wall of the lid. In case of contact displacement, we offer instructions:

deactivate the smartphone, disconnect the cover and remove the battery;
find the battery contacts;
take a small screwdriver and remove the connectors;
Install the battery correctly.

Android glitches

In some situations, the system breaks down and becomes damaged. Because of this, various violations occur associated with certain nuances. Incorrectly installed updates, viruses and system failures affect this. If you used external media, then take it out and wait a while.

If the problem disappears, clear the card via your personal computer. Insert the memory card into the Slot, go to the “My Computer” tab, right-click on the “Format” button. Before doing this, transfer important files to separate media. During the formatting process, all files are destroyed. If you have not used a USB flash drive, perform a full reset. The “Hard Resert” key will clear the gadget of all data.

Button retraction

From time to time, liquid or any other debris gets into the “Power” key. Check to see if your device is experiencing this issue. Study the button, remember the situations so that the gadget ends up in water.

In addition, look to see if there is pressure on the key. Most often, this leads to a constant restart of the gadget.

Faulty equipment

If the above did not resolve the situation, but the android also turns off without stopping, most likely a serious breakdown has occurred. If the gadget is under warranty, return the device to the store. Most likely the device will be repaired or replaced with a new one.

Ask a Question

Google Installer does not install and does not load services: reasons, what to do?

Motherboard defects and manufacturing defects

This problem is associated with the gadget falling onto tiles or any other hard surface. In some situations, inquisitive owners open the gadget to examine its insides. Awkward movements lead to damage to the motherboard. If such a situation arises, seek help from a specialist. In turn, factory defects occur quite rarely. All smartphones are carefully checked before sale. However, if you are “lucky” to purchase such a model, then return the device under warranty.

Firmware

For any device it is necessary to update the firmware. If the phone starts to freeze and glitch, then it is recommended to clear the cache. A full memory negatively affects the operation of the device as a whole. The developers recommend performing a full reset to factory settings. Before that, try updating your smartphone. Download the new firmware from the official resource. Check the phone's functionality.

Memory problems

Installing different programs of the same type on one device is not recommended. A software conflict will arise, which will lead to a breakdown. Most often, photography applications, GPS, and various antivirus services interfere with each other. It is recommended to leave one version of the program on your smartphone. Format the internal memory and get rid of such services. If the problem is not solved, click on “Hard Reset” and turn on the mobile phone again.

Reboots itself after a shock/fall

Everything is clear here: any of the phone’s modules could fail, or one of the cables could have microcracks. To determine exactly the damaged element, you will need diagnostics with disassembly of the device. This can only be done at a service center.

Do not try to disassemble the phone yourself. This way you can only make the situation worse by damaging other modules. Do you need this?

The Android phone gets very hot when talking, playing games, or using applications.

Moisture ingress

Water is an excellent conductor of current and, when it gets inside the phone, it can cause the closure of various contacts, from the power button to the battery controller. The result is random device shutdowns.

In this case, drying the smartphone will help. To do this, you need to remove the back cover, disconnect the battery and use a household hair dryer or place the gadget on a heating radiator. In order not to damage the plastic components, you need to monitor the heating temperature - it should not be higher than 45-50 degrees Celsius.

Check system updates

It is very important to download and install the latest system updates to keep your smartphone in working order. Yes, updating Android may not always be convenient as it takes a lot of time. But updates bring new features and protect your Honor from the latest security threats. When it comes to Honor constantly rebooting, an Android update can solve the problem.

I will show you how to check for an update in Honor 10. To do this, follow these simple steps:

Open Settings .
Go to the System .
Select Software Update .
Check the latest version of EMUI.

EMUI is an operating system created by Huawei for its smartphones (including Honor).

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.

Then only installing a licensed Android OS will help. At the very beginning, I recommend doing a reset, or even better, a hard reset, called a hard reset.

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.

Hardware faults

Hardware problems often affect the phone turning on. There may be several reasons:

Overheating of the processor or other parts of the gadget. In this case, you need to pull out the battery and let the phone sit unassembled.
Malfunctions of control elements - various controllers may fail. For example, when a charge controller fails, it can always inform the smartphone that there is no charge on the battery, and accordingly the phone will immediately turn off. Only contacting a service center will help here.
Oxidation of terminals and contacts. This usually happens if the phone was “drowned” in water, or it was left in a damp room for a long time. You can remove the battery, check and carefully clean its contacts; it’s also a good idea to check the terminals on your phone.

The solution is simple - remove the battery and clean the terminals, or leave the smartphone charging for a day.
