The pedometer stopped working on my S5. Also I am having intermittent problems with screen rotation. If I reboot, the pedometer counts steps to about 35 and then stops. I have tried a factory reset, but still no change. Has anyone else seen this problem, and if so how did you fix it? I have installed all updates and upgraded to Lollipop. I am thinking that I may have to use the warranty on the phone, but I am hoping someone has a fix.
