Help: I always flash when I first enter csp every day.

If the phone screen flashes, we recommend that you:

1. Check whether the display update function is turned on in the developer options: Settings-Developer Options-Display Update-Off (some machine developer options are hidden, so you don't need to check if they are not activated).

2. Shut down and restart the machine and observe.

3. If the mobile phone can be used normally, it is recommended to check whether there is a new version of the machine system and try to upgrade the system.

4. If it is invalid, back up the data (contacts, text messages, pictures, etc. ) in the phone, and then restore the factory settings.

If the mobile phone can't work normally or the problem still exists after the above operations, it is recommended that you take the purchase invoice, maintenance card and machine to the local after-sales service center for professional engineers to help you test it.
