Hello. We apologize for the inconvenience.
First of all, it is recommended that you can check whether this phenomenon occurs when a single contact dials, if so, it is not excluded that it is caused by the other party's network or the other party's mobile phone is abnormal, and it is recommended that you try to see if there is a corresponding operation for other contacts to call.
If the other contacts still have incoming calls, then:
If your device is turned on, but others call your ** prompt to shut down, it is recommended that you first check whether the relevant whitelist or blacklist function is enabled, and please turn off the function.
If it is not caused by similar functions, you need to check whether it is caused by a poor network signal in your location, and it is recommended to try it in a location with a good signal. It is also recommended that you try to change the SIM card to rule out whether it is caused by SIM card failure.
If the preceding operations do not work, we recommend that you back up your data and perform a factory reset attempt to rule out whether it is caused by a system abnormality. If restoring the factory settings still does not solve the problem, you need to go to the Lenovo repair site for testing and maintenance in time.

The best solution to this situation is to see if it is caused by software, for example, what software you have installed, you can first factory set the mobile phone, if it will be like this after the factory setting, then the best way is to use another mobile phone or something like the video to record the restart process, and you can have a voucher record when you get it after sales, because the restart is not a regular or fixed frequency, so there may be no restart after sale, and the after-sales service may say that there is no problem. Personally, I think your situation should be the hardware or quality of the mobile phone will be like this,Lenovo mobile phone itself has also had this kind of situation,And there was a lot of uproar,Lenovo pushed the Z5 mobile phone for the Z5 mobile phone pushed the stable version of the update,But many users reported after installing the update,The mobile phone has an abnormal automatic restart problem。 Yesterday, a user who was certified as a zui engineer posted a response in the Lenovo community, saying that the cause of the incident had been identified and apologized. The reason for this problem is that Lenovo needs to update the list of game apps in order to optimize the game mode feature during the iteration of the new version.
This profile is not compatible with the ZUI version, resulting in the phone restarting when the phone is turned on or when the application specified in the installation list is specified, and the phone will eventually enter recovery mode. As for the solution to this problem, the engineer said:
For users who haven't had the problem yet, don't worry, the system will automatically update the relevant configuration files, as long as you try not to shut down these days, the phone will automatically get the correct configuration file from the server side.
For users who have already had problems, the official recommendation:
Turn on the machine several times. How to do it: 1) Insert a SIM card or in a WiFi environment (it has already been connected).
2) Under the following interface, when try again is highlighted, press the power button to achieve restart, so try to flash the phone at a nearby Lenovo service station several times, and we will provide a special version to ensure the security of user data.
Therefore, Lenovo's situation is not a single event or an occasional event, and Lenovo's mobile phones are not very good at quality control optimization.
