Hi All, I dropped my Note 4 a few times in the past, with no issues. However, on vacation last week, it fell only a few inches (perhaps on its edge), screen went dark. I pressed down on the screen, evenly across, luckily it came back on, but with pink hues. Next I pulled the battery out, once again pressed down evenly across the screen, it came back to its original state! I'm sure theres some damage internally, should i continue to use the phone, more cautiously, with a TPU case now... everything seems normal? or should I get it replaced, I have ATT warranty? Appreciate some thoughts and feedback.
