Hey everyone. My Galaxy s4 sgh-i337m recently been acting strange like screen not turning on only capactive buttons light up. Notification led lights up and there is power on sound Tried this method on YouTube : and yay.. at least got the phone's screen turning on. But... sadly it only flickers and turns right off. After I fully turn the phone on, I press the power on button once it flickers again and then the cap active buttons light up. Once those turn off, I press it again, flicker again and it keeps repeating. Help is apperciated. I managed to capture the flickering moment by luck.
