What if Meizu's mobile phone software always flashes back?

When there is a software abnormality in your mobile phone and the program automatically rolls back or flashes back, Charming suggests that you first clear the application data and cache to solve some minor bugs encountered by the application. Operation: Open the phone settings-> Application management->; Select failed application-> Clear data or clear cache. Note: Clicking "Clear Data" on the third-party APP will clear the software data. Please back up the data before operation! ! If the fault still exists, you can try to back up the data and upgrade the phone firmware to see if it is back to normal. If you can't solve it, you can send it to official website for quick repair, or send it to the nearest Meizu Experience Center for repair! !
