The display screen on my Samsung Galaxy Note 10.0 note goes fussy and the screen does not always respond to touch. I don’t know if it is the screen only or the digitizer. The tulips are my screensaver and what happens is that the edges of the tulips start becoming fussy and the colors start changing. Please let me know whether I should buy a new digitizer and if so please let me know how to install it.
That sounds like the LCD. The digitizer wouldn’t change any coloration. Also take in to consideration if you left this device in the direct sun for a long time or in a vehicle it may be a GPU overheating issue. If not. I’d say LCD. Just my opinion. Good luck.
I faced the same problem before. I sent it for repair and the technician said it was due to a flex cable problem. After replacement, it can be used as normal.
