For those out there who are as unhappy with the screen and digitizer as I am; I have some good news…
My screen looked grainy, my finger felt like it was dragging on a rough surface when I drug it across the screen, and like so many others, I was having to double or triple tap to get the screen to acknowledge my touch…
Well, I have a partial solution… Change The Screen Protector! The stock/free protector we all got pre-installed is (like Gearbest, oops GearWORST) HORRIBLE! It defiantly is not as clear as clear as the replacement I just installed. The roughness is gone. And finally, the responsiveness of the digitizer is better, I wish I could say it fixed this problem but it does help and every little bit of help goes a long way.
Now finding a screen protector, at least in the US that fits is difficult, but I did find one that is close enough for me. It leaves aproximately 1mm on top & bottom, and 4mm on the left and right exposed (when held in the landscape orientation). But since these areas are well outside of the touch area, I am comfortable with this.
The Replacement pack (x3) I ordered on Amazon is here if your looking for a inexpensive fix to a couple of the many problems this device has:
