[AC Question]

I have a Galaxy 4 and appears every few days one of these faults:
- Constantly jumping a system interface does not respond
- Another fault appears it's pretty much a flickering screen every second mobile phone and the device itself does not react (see the Home screen on the device properly every 2 seconds around the screen goes black for a few hundredths the problem you can not do anything over the phone).
The only solution that can stop the bugs is to remove and return the battery.
I've reset the device to factory settings and it did not help.
what can we do?
