Good morning. My A71 screen is blinking on and off black screen. What can I do to fix it? Also when I'm attempting to type in any chat I have to press down really hard to get the letters on the screen? As my phone heats up it goes black,if I'm in a room that has AC units it remains on for a longer period of time.
