I'm having a serious issue with my Google Apps recently. My stock rom updated over OTA so I had to re-root/reinstall CM11, and when I was installing Google Apps it failed a few times and then worked.
The problem I'm having is that Android Device Manager will be very inaccurate (up to 2,400 meters), and sometimes won't find the device at all. When I am running my stock rom the ADM finds the device very accurately (<10 meters).
I just re-flashed/reinstalled everything and I'm still getting the same issue. Any suggestions?
