Iphone display screen screwed up?

My iphone screen always flickers randomly sometimes it works sometimes it just totally flickers and goes black and i can't use it I don't understand why, it should work or it shouldn't work. Any help? Should i open it up and is there an easy fix or should i just get a new one through apple care which will cost only $49.

Apple care it. Your screen connection is loose, if you still have your warranty you should return it. If you don't i would crack it open and see if you can't fix the connection

  • We know that if a smartphone has more than 300 pixels per inch, it is a retina display. How much ppi it need to be a super retina display? It is said that human retina can distinguish pixels and letters in screen seem broken if ppi is below 300. If ppi is above 300, how high the ppi may be, it looks same for human eye, then why iPhone has 458 pixels in iPhone x?

  • My iPhone 4's volume is screwed up? About 4 months ago, I put my iPhone in my pocket book with my lipgloss. The lipgloss coated where the sound comes from on the bottom. Then about a month after that my phone was dropped in water. My phone didn't act up, yet when I took a video or listened to a voice mail, the sound was extremely low… Even if it was up all the way. If I play music or watch videos, the sound is perfectly fine… How do I fix this?
  • Is my iPhone's battery officially screwed? Last night, I was charging my iPhone battery overnight. This morning, I woke up to it - it was still charging, but the screen was on that low battery screen. It's still on the low battery screen right now - even though it is still charging. Does that mean my iPhone's battery is officially screwed?
