I think my GPS may be broken! Here's what happened.. I've had the note 4 for a while now with no problems.. Tried out several different ROMs including Infamous, Dynamic Kat, and Hyperdrive. Decided to try the Canadian lollipop firmware which is supposed to be 100% compatible. GPS worked once and then stopped and hasn't worked since. I've tried other lollipop ROMs then went back to KitKat, including Dynamic Kat which is what I was on before lollipop. Still no GPS. Flashed back to stock NK4 firmware via Odin but still no GPS. Even went further back to NIH firmware then did an OTA update to MK4...nothing. So what do you think, is it broken? If anyone has ideas of what else I can do I would be very appreciative, thanks!
