When using phone, the right side of the screen becomes frozen and will not change. Have to turn off and let set for several min. before it restores to full screen. If I turn off the phone during the freeze, the right side goes all “fuzzy” like when you change the TV to a dead channel.
I got it fixed. It turned out to be the faulty battery that caused it. Strange but true. I replaced my battery with Duracell battery for Note 4 and the problem disappeared ever since. Hope this helps.
just change it & display will be ok
