I have a Samsung galaxy s4. Lately I've had nothing but problems with it. Mostly the batteey. Normal use and by about noon, the battery is dead. I rooted it and used apps such as lean DROID and other root power saving apps and still not helping. I then tried cynogenmod and had nothing but problems. Couldn't make and. Receive calls etc. Finally getting really frustrated I changed it back to stock rom. Some reason I'm running re same software and it is rooted again but my battery is lasting all day now. Only problem is my gps isn't working. It is on and enabled. But it's way off. Google maps shows me moving when I'm moving but it shows me a city over jumping streets. It's way off. I don't want to do anything drastic because I've had so many other problems. Just want my gps to work. I've rebooted the phone. Both Google maps and waze are not working. Google maps shows me a city over jumping streets. Waze just says it can't determine my location.
