I have the following problem; I get an instant fix and a bunch of satelites as soon as I start the GPS and an app that requires the GPS. Even from inside of the building I'm getting 3 or 4 satelites and the fix. But after some time (1/2 - 5 minutes) I loose the fix for about 20 seconds, then it's back. After a couple of minutes it happens again and again. In the time as I don't have the fix, the 'GPS Test' freezes - if it ran before or it doesn't show any satelites - if I start it in the time as no fix is there. The problem exist from the moment I've got the Redmi. I've changed from the 'shop' rom to MIUI 7 Global to MIUI 8 Global. No improvement. I would exclude a hardware problem since there is always the same pattern (mentioned above) and it happens also if thephone isn't moved. It seems to me, like some proces stops the GPS Tracking, but the tracking restarts after some seconds again... I'm sorry, but I don't find an explanation and solution for that. Any ideas? Is this issue known to anybody and would it be solved if I install the eu rom?
