So i had dropped my phone and it smashed the screen, I had bought a new screen and replaced it at home with my husband ( we are pretty well versed in this ) everything went FLAWLESS - camera work, 3d touch, touch ID, exc everything was fine…..then for some reason ONLY when i open apps the bottom of the screen doesn’t react correctly….if I’m on home screen its fine i can touch the apps just fine on the bottom…once i get in an app anything on the very bottom doesn’t react correctly …( example: in Facebook the bar at the bottom if i touch notifications it will just open the bottom part of the feed showing )

  1. I’ve established that the bottom part of the screen DOES work
  2. Doesn’t seem to be software related I’ve reset and restored
  3. I opened back up and checked the connectors At one point it went back to full function for about 30 minutes and then stopped again …It doesn’t add up to being a faulty digitizer …ive read cleaning the connectors with alcohol helps….has anyone come across this.

Ok so I FIXED IT! - and i hope someone can maybe explain WTF I did LOL! I remembered reading somewhere that a screen protector helped with an issue like this but blew it off because thats ridiculous…..I took this phone apart 3 times , cleaned everything, inspected the connections and nothing……i broke down…must be defective screen and ordered another screen….but figured hey since i have a new screen coming lets just see ….took a slice of packing tape and put it over the screen ( didn’t have a screen protector ) …..INSTANT FIX!!!!……..took the tape off….STILL WORKS…im so confused LOL what the heck did the tape do LOL

Try do soft reset… pressing volume down and power button
