The most common causes of unexplained reboots are:
- Mechanical damage to the device (impact or fall from a height).
- Software disruption.
- Battery failure or other power failure.
- Malfunction due to temperature influences – overheating or hypothermia.
- Moisture penetration into the device.
- Phone memory overload.
Let’s take a closer look at each of the problems and options for solving them.
Mechanical damage
Have you noticed that a phone that has been dropped or hit on a hard surface spontaneously restarts? It is highly likely that the reason for the reboot is mechanical damage to the device filling. A breakdown may consist in a malfunction of the board or its components, and the release of the loop contacts.
In any case, to identify and eliminate the cause of the malfunction, the device must be disassembled. This should only be done if you have an ultra-thin soldering iron and a good amount of patience to thoroughly examine the board and every contact of the system.
To disassemble the mobile phone and access the contacts, all panels must be unscrewed and removed. Then inspect the board: are all the contacts of the loops well fixed.
If it was possible to identify a loose contact, it must be carefully soldered. Then assemble the device by screwing the panels in the reverse order.
Now you can turn on the device and check its operation. If the performed manipulations did not help and the smartphone spontaneously reboots again, we recommend visiting the service center.

Software crashes
Experienced users and experts call the cyclical reboot of the smartphone due to software problems the most easily solved malfunction. Often the reason for the failure lies in an incorrectly installed update, a crooked utility, or a failure in the operation of communication modules.
To solve the problem, perform the following steps:
- They take out the flash drive from the smartphone and reboot the device.
- They manually delete unused programs from the phone’s memory or use applications like Clean Master for this.
- If the problem persists, perform a factory reset.
In order not to surf the Web for a long time in search of combinations for resetting the settings, we suggest finding the one you need in the table:
| Smartphone brand | Keyboard shortcut |
| Lg | volume down + Power |
| Huawei | volume down + power |
| Samsung | volume up + power + “Home” |
| Prestigio | volume up + power |
| Sony | volume up + power |
| Lenovo | volume up + volume down + power |
| Asus, Aser | volume down + power |
| Xiaomi, Meizu | volume up + power |
Another reason for problems with software can be a viral application. Removing all third-party programs from the device or returning to factory settings will help eliminate bugs.
You should also install any antivirus application (for example, Avast). It will additionally monitor the gadget for virus infection. If uninstalling applications, clearing memory, and factory resetting did not solve the problem, you may need to replace the firmware. It must be performed by a master at a service center.

Faulty battery or power system
Netizens claim that a common cause of frequent phone reboots is battery malfunction. A smartphone with a one-piece body and a non-removable battery will have to be carried to the service.
If self-diagnosis of the battery (battery) is possible, disassemble the device by removing the back cover. Then inspect the battery. It should be flat, with no bulges or depressions. The surface is free from smudges, rust, stains. These are all signs of malfunction. If they are determined visually, it is necessary to replace the battery with a new one and check the operation of the smartphone.
In addition to battery problems, the cause of the bug may lie in oxidation or loose power contacts. To calculate the breakdown, you need to follow these steps.
- Clean contacts with a cotton swab from dust, dirt.
- Remove oxidation with alcohol, nail polish remover.
- Apply an electric screwdriver to the contacts one by one, checking in this way whether power is supplied to them: the indicator lamp will light up if everything is in order.
- Having found the outgoing contact, it must be carefully soldered. Soldering should be done very carefully, not overheating the cell, otherwise the contacts may close. If in doubt about your abilities, seek help from an experienced master.

Temperature effects
Severe overheating or hypothermia can easily become a reason for constant reboots. If you suspect that this is the case, try to exclude exposure to too high or low temperatures on the phone.
If the smartphone overheats while charging, immediately turn it off and let it cool down. It is also important to get the battery out (if possible). When the device cools down, turn it on again and check if it works.
Often a reboot occurs due to a stuck power button. Try prying it off with a pin or paperclip to remove the SIM card. If the cause of the malfunction is in this key, the restarts will stop.
Moisture ingress
Sometimes contact with moisture can cause the phone to reboot. If you have recently been exposed to rain or other contact with liquid, it is important to dry your smartphone well. The most affordable and easiest way to do this is with rice grits.
To do this, disassemble the device: remove the cover, panels, remove the battery. All elements of the smartphone are placed in a container with dry rice so that the cereal completely covers them. Leave the device in the container for a couple of days. Rice is a strong absorbent that will absorb moisture trapped on the components of the device.
After a couple of days, they take out the smartphone from the cereal, collect it and check its performance. If the cause of the malfunction was moisture, the problem should go away.
Overloaded memory
According to user reviews, overloaded device memory is often the reason for sudden reboots. To fix the problem, it is enough to clean the storage of photo and video files, remove unused applications.
Please also note that a lot of space in the smartphone’s memory is occupied by residual files of deleted programs, phone software, and cookies. To perform high-quality cleaning, we recommend downloading and installing special applications on your phone, for example, Clean Master.
Now you know: frequent reboots of the gadget does not mean at all that it is defective and it’s time to run after a new one. It is enough to independently diagnose using the recommendations from this article, and the smartphone will most likely return to trouble-free operation.
