Dear Lenovo mobile phone users, hello!

If the mobile phone often crashes, if you exclude some factors such as the surrounding network environment, temperature, magnetic field, etc., there are mainly the following situations, you try to confirm and operate:

1. Third-party software is not compatible, try after uninstalling related programs (especially if it always crashes after opening and running some software);

2. Too many background programs cause the current program to have insufficient resources to cause a crash, you can then close some unimportant background programs and observe them, or through some optimization and cleaning software, to optimize the use of the system (like Le Security, 360 Guard, LBE Security Master or something);

3. The system files are unstable, especially the rooted phone, try to restore the factory settings of the phone and observe the use (pay attention to backup the body contacts, text messages and other important data).

4. It may also be caused by abnormal internal wiring, virtual soldering of motherboard-related components, and abnormal (damaged), so it is recommended that you take the time to go to the local Lenovo after-sales service center for testing and solving.

This could be a problem with your phone's motherboard system or a broken battery.

1. If you buy a new mobile phone, it may be that the battery is out of power and it will not turn on, try to charge it for half an hour and then turn it on.

2. Remove the back cover of the phone, remove the battery and turn it back on.

3. If the battery is charged, the boot has a response, and it is stuck in the boot interface and cannot enter the system normally.

If there is no damage, it is a system problem, and it will not be flashed, and it is recommended to sell it.
