Ask the question that when the Note2 7102 phone is directly charged, the back cover will pop up when

Maybe the battery is a little loose, right? You put the battery on, and then put a slightly layer of paper between the back cover and the battery, the purpose is to keep the back cover in close contact with the battery to avoid loosening. Pad the pieces of paper and see if this happens?

Because this situation only occurs after you tap (vibrate) the phone, it should have nothing to do with the software. It doesn't matter if you have root or not. If the situation disappears after the pad is padded, then consider whether your phone is really in China, or whether the battery has been adjusted.

This has never been the case with my note2. The battery is very tightly packed inside.
