today, i saw my lg g2 screen discolored, as there is an interference of the green color and purple. when i take a screenshot of the phone, the picture shows there is nothing wrong. possible somethgin wrong with digitizer, i don't know. it is better show on the picture. i took a picture of the screen with another phone, and a screenshot also. it was dropped early on today, from a couch onto the carpet, not a huge drop. i checked it immediately and it was fine. hours later i saw the discoloration, and like i stated, the screenshot shows a normal screen (ruling out GPU problem), two of the pictures are the screenshot normal screen
what should i do? how to fix it? what have caused it?
Additional information: when i stop using the phone for a while, the color return to normal. after i used it for couple of minutes 5-10 minutes, the issue return and the screen gets more purple as time of use increases
performed Hard reset, reinstall ROM and kernel, issue persisted
