Remember the number when you make a phone call, and it will disappear after the phone call. How should I find it?

How to deal with the inability of Android phones to save call records;

First, adjust the mobile phone system time: when the mobile phone system time is set incorrectly, the call record cannot be saved. You can manually reset the correct phone time and date, and then try again.

Second, exit the guest mode: when some mobile phones are in the guest mode, the call records cannot be saved. You can exit guest mode and try to save again in normal mode.

Third, adjust the call record display: When the call record filtering function is turned on, the address book display is incomplete, which leads to the mistaken belief that the number in the call record cannot be saved successfully. You can enter the call record setting interface, select Show All, and then try to save.

Fourth, format the memory card: Duplicate memory card files or file errors will also cause the call record to be unable to be saved. You can back up the data in the memory card, format the memory card, put the memory card back on the phone, and try to save the call record after restarting the phone.

5. Clear the stored data of calls/contacts: You can try to enter Settings-Application Management, and after clearing the stored data of contacts or calls, choose whether it can be saved normally.

6. Restore factory settings: If all the above methods fail, you can back up the data and enter Settings-Privacy Settings-Restore factory settings.
