Hi! My mother called me today telling me she had changed her A3 to black and white display (she has no idea how or why) and wanted me to try and fix it. i googled on it and found similar problems on S4 and S6 but nothing on the A3. The only thing i found and checked was if the ultra or any power saving modes was on and that was not the case. Was hoping anyone could help me solve the issue or come up with some more suggestions on what could be wrong.
