Had the same problem three times on the same handset . Every time , Samsung took my phone for over 2 weeks with no loaner in the meantime and returned it with a few random parts replaced . Refused to replace the unit even after repeats of the same malfunction . Phone worked properly for a few months until the exact same flickering started , then it got to the point where if the screen locked , I had to take the battery out and put it back and reboot in order to get the screen working again . I ' m about 5 weeks from my contract being up , and the flickering is starting again . <| sep |> I ' m level 27 and I think I ' d caught 150 mons over 2 days before I finally found a Ditto 453 CP . Then I found another 4 catches later .
