sweet_potato as far as my experience go it is a software issue.i used to have a samsung a 71 I damaged its mother board display area by over heating ,that phone also got green tint but that was different (hardware issue),I sincerely hope it will be fixed in 3.0 official release with the charging issue of 2a. Or this might as well be my last nothing phone that’s for sure. For the time being I am switching to light mode, don’t know that will fix it.
