What to do when the phone turns on and off. Samsung smartphone turns itself off and on

A mobile phone is considered a huge multi-functional system, equipped with a powerful processor, large built-in memory and great functionality.

But sometimes the equipment fails and the phone starts to “fail”, for example, turn on and immediately turn off. Not in all cases it is worth contacting a specialist, often you can fix the problem yourself.

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

1. Overheat processor or other parts of the gadget. In this case, you need to pull out the battery and let the phone lie down in disassembled form.
2. Faults control elements- various controllers can fail. For example, when a charge controller fails, it can always inform the smartphone that there is no charge on the battery, so the phone will immediately turn off. Only contacting the service center will help here.
3. Oxidation terminals and contacts. Usually this happens if the phone is “drowned” in water, or it has been in a damp room for a long time. You can remove the battery, check and gently clean its contacts, it will also not be superfluous to check the terminals on the phone.

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

Software bugs

The spontaneous turning on and off of the phone or tablet is also affected by software failures and violations.

The problem may be:

• installation incompatible software- Resetting the settings and rebooting will help;
applications;
• malfunctions ON- flashing the gadget can help.

Charging or battery problems

Most mobiles that failed were exposed to water. Process oxidation happens for a very long time and it is impossible to predict how the device will behave next time. There are several: hair dryer, leave overnight on the battery or move to a warm place.

Other Solutions

When the phone constantly restarts, turns off or turns on by itself - this speaks first of all of what is happening failure software ensure. Also, the reasons may be hidden in mechanical damage after a fall or shock. In these cases, you can go to the master to determine the breakdown.

But often the reason why a smartphone or tablet turns on and immediately turns off can be a trifle and it is possible to fix the problem yourself by flashing the device or resetting it to factory settings.

Phone turns off by itself

Initially, you need to determine the reason for turning off the phone:

• software failure;
• mechanical damage;
• incorrect battery operation.

If, as a result of a fall, the smartphone ceased to function normally and began to turn off, the reason is damage details instrument. If there are no mechanical injuries, then the battery is good and the problem is with the software.

Mechanical damage cannot be repaired with your own hands, so you should contact the repair.

Battery is defective or loose

The main reason for the breakdown of most smartphones is moisture ingress. To save the gadget, cleaning and drying is required, otherwise the phone may become inoperable. If the battery is defective, it must be replaced.

Battery can just walks away and you can put a thin sheet of paper or cardboard between the back cover and the battery. If the battery is in working condition, then you can only clear terminals from pollution and the problem will be solved by itself.

Low battery

This can happen at any time, even when the charge is full, or maybe at 40 percent, 15 or even 5. If the phone turns off at 5/15/25 percent of the charge, you need to do a full reset and clean the device. Then the battery should be recalibrated. If the situation has not changed within 2 days, you should contact the master.

Viruses

When the phone or tablet turns off on its own with a charged battery, it's time to check the device with an antivirus. It is viruses that cause most smartphone malfunctions. You should use an antivirus program to prevent infection of the device.

Software issues

There may be several problems with the software:

1. Not enoughmemory. In this case, you need to free up space.
phone. Do not clog the device with unnecessary programs.
2. Virus. The pest must be found and eliminated.

System failure

The phone may turn off even when fully charged. The reason may be a failure in the device OS, most often due to wrongfirmware. You need to repeat the firmware procedure or contact the service. If the problem still persists, it's time to upgrade. The device may be malfunctioning by itself.

If the device starts to freeze, then the problem is probably in the flash card. It can be simply changed.

When the phone heats up and turns off, there is probably factorymarriage. It's good to have a valid warranty.

One of the worst and most expensive reasons is damagefees when there are no other options other than replacement.

In conclusion, I would like to note that with careful use, the probability of uninterrupted possession of the gadget is very high. Technology, like people, also needs to be treated with care.

It happens that various models Samsung smartphones turn off, turn on (or reboot) by themselves, i.e., do a spontaneous reboot. This problem is typical for devices of this brand and causes a lot of inconvenience to the owners. Let's try to understand the reasons for this behavior of Samsung. Consider:

• Software or OS failure;
• Damage to internal components;
• Service Center recommendations.

Often, Samsung smartphones turn off and on by themselves when faulty battery. The reason may be natural wear, mechanical damage or moisture on it, resulting in swelling and loss of energy intensity. Extremely bad for batteries long time stays in the open sun, near heat sources, or vice versa - in the cold. An incorrect charge-discharge mode leads to battery failure. Modern models require you to keep the energy at the level of 40-80%, you should not wait until the charge reaches zero, and do not leave the phone connected to the mains overnight. In any of these cases, in the event of a breakdown, you will have to replace the part with a new one.

Software or OS failure

The reason for spontaneous reboots may be failures in the OS or software. Perhaps there is a conflicting application on the smartphone that does not get along with the firmware, or the matter is in the firmware itself. You can find an incompatible program and remove it or reset all settings to factory settings using a hard reset. In the latter case, all data from the phone will be deleted. Another measure is flashing Samsung.

Under the influence of water, the battery swells - it internal organization very sensitive to moisture and changes in environmental conditions. If the breakdown has occurred recently, the cell phone starts turning off and on. In the later stages, the smartphone stops turning on at all. In this case, it is better to contact the Service Center for diagnostics and troubleshooting.

Damage to internal components

Mechanical damage or wear of some elements provoke Samsung smartphones to turn on and off spontaneously. For example, the wear of the cable leads to a short circuit in the power circuit, and the impact from falling the phone leads to processor failure. In any case, you will have to take your Samsung to the Service Center for diagnostics and replacement of defective parts.

If a Samsung smartphone turns itself off and on, this indicates a serious problem that is difficult to diagnose on your own. The service workshop engineers will conduct an inspection to identify the true cause of the breakdown, consult and, if necessary, replace the defective elements.

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

To exclude 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 to check the phone, but also to "cure" it if necessary.

Applications

On this list possible causes the emergence of our today's problem does not end there. Why does a Nokia phone or any other 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 the phone.
