Below are the following check points to avoid or fix a hanging or freezing screen display.
A. Check the Battery Capacity and Charge
Check the device’s battery and charging status by swiping down the status bar from the right top corner of the screen. This is to check if the device is charging normally or the battery is low which causes the screen to hang or freeze.
B. Storage space running out. MUST free some space for the device.
It is recommended to regularly backup the internal storage files or delete some unused files to have more space. The device will also notify once the internal storage is out of space as shown on the picture below:
