Well, I accidentally flashed a Note Edge ROM on my Note 4. I odined back to stock but my screen isnt responsive to the touch. Just to give you a visual picture of my problem, I attached a photo of a Note 4. Yellow region is working area. Red region is non-working area. The purple dot is where i need to press in order to open "Apps". Likewise, green opens "Phone". It looks to me that the working area was compressed towards the top left. The display is perfect, just the touch area seems to be moved.
