Why does the phone crash when I make a phone call?

It may be caused by abnormal operation data of the mobile phone, and it needs to be tested at the service center, subject to the test results. If you use a vivo phone, you can refer to the following methods:

1. 1. Forced restart of mobile phones, and methods for forced restart of various models:

① Press and hold the top round key 10 second or more to forcibly restart the mobile phone (NEX 3/NEX 3S is applicable);

② 2065438+models listed after September 2007 (X20 and later models) and new models listed later: press and hold the "power button"+"volume down button" 10 second at the same time;

(3) Vehicles launched before September, 2065438+2007 (vehicles before X20): press and hold the "power button" 12 seconds or more;

2. Upgrade the system version;

Step 3 clean up the storage space

When the storage space of the mobile phone is insufficient, it may cause a crash. Enter the mobile phone I manager and click space cleaning. After scanning, click "one-click safe cleaning" to delete the junk cache files, and uninstall the infrequently used applications according to the page recommendation, so as to keep enough storage space (it is recommended to reserve more than 20% available space).

4. If the crash is caused by software, try to clear the software data or reinstall the software;

5. Restore factory settings: Redundant files generated during the use of mobile phones may affect the stability of the system. It is recommended that you clean up redundant files or configuration information by resetting your phone after backing up important data.

Operation method: Go to Settings-System Management-Backup and Reset-Clear all data (some models are Settings-More Settings-Restore Factory Settings-Clear all data), click Enter, and follow the onscreen instructions.

Clearing all data will restore the mobile phone to its initial state and delete all data in the system space of the mobile phone, including account number, system and application data and settings, and installed applications. Please back up your data in time before operation.

6. None of the above methods can be restored. You can take the mobile phone to the service center for testing and processing.
