I received an LG G2 a few months ago as a replacement for an S4 from sprint. The gps on it was always a little off but it worked well enough until the past few weeks now it wont maintain lock on maps at all i'v tried factory resetting it and a few different apps from the store but nothing seems to work.
Thank you for reaching out to us. We advise you to take the device to one of our Sprint Repair center so you can have the device check since you already did a master reset and the issue persist. Please go to Sprint.com/storelocator to check the closest store to you.

after you did the FR did you test it before adding back on any of your apps just in case its being caused by one of them? if you didnt you can probably just boot the phone up into safe mode so it disables all 3rd party apps etc and then test again to see if its still having issues or not.
I've gone to two different Sprint stores each time coming out with my GPS still being a problem. They dont seem interested in helping me with my issue just getting me out of the store as quickly as possible.
