Why Does my phone screen sometimes shake

Hi @tugagh,

Has the phone been dropped or gotten wet at all?

Try starting the phone in safe mode just to eliminate the possibility that a downloaded app may be the cause of the problem.

If the screen still shakes when the phone is used in safe mode then the phone will have to be opened and checked.

It may be a loose LCD display flex cable connection or worst case a faulty LCD display.

Here’s a video that shows how to replace the display which may help. The flex cable is shown being disconnected at approx. 1:05 minutes into the video.

Replacement LCD displays are available online. Just search for Galaxy A2 Core LCD display to get results for suppliers that suit you best.
