Any luck with this? The factory reset didn't work for me on my Sprint S7, I still have GPS issues and now I've lost app data to Runtastic and ToMarket
GPS settings are the same as DankNuts.
Since the nougat update, It happens every time I use Runtastic (every other day). When it happens, I notice that Maps is also showing the wrong location (anywhere from where I'm at to a mile away). I've tried the app GPS Test (clearing and updating AGPS) and numerous phone restarts. At first those seemed to work. Now I try clearing the cache of apps that use GPS and that has worked long enough for my 90 minute run.
One thing that I just realized now, is that when I start Waze or navigation I don't seem to have the problem. I may need to test with a combination of those and Runtastic.
