I saw this bug back in the Android 2.x days. Until Google issued newer versions it happened a lot. Also, if you installed any apps you find the maker has you hard reset it and see it working again. Once you install any app, you don't find support.
I have a few problems a SGS2 and SGS3.
On the S2 rotating screen is not as it should. It rotates from portrait to landscape, but not back ...
On the S3 the light dimmed in the Internet app. When I try to adjust the colors from Level 3 (High powersaving) to "Standard" it goes back again after I close the app. So I have to change it every time I open it.
Anybody can help me with this
(sorry for my bad English )
