I'm doing a app to collect pure GPS locations. So I choice use locationmanager whit ACCESS_FINE_LOCATION.
I don't want use google play services to locations because, I believe, it joins locations from various providers without user control.
I want a specific app to test the device GPS chipset, so I want only GPS locations no matters what time it become ready.
I do a app as described and it works fine in my cellphone Xiaomi Redmi S2 whit android 8.
But in a cellphone Quantum MUV with android 7 it don't get any locations.
Somebody knows some specific issue about location manager running in android 7 or in Quantum MUV cellphone?
