    Got a oneplus 6 from Chinese on Day 1. Installed google map, but did not use it until today.
    The problem is, whenever I re-open Google Map, I don't receive any GPS signal.
    If I close Google Map from the multi-task page and open it again, GPS signal is back. However, as soon as I switch to any other app and switch back, the signal is again lost.

    In pokemon Go, there is no GPS signal whatsoever.
    Zomato (a yelp-like app) works fine.

    I'm in the centre of the city of Sydney, Australia. Android 8.1.0, H2OS System up to date (Oneplus A6000_22_180522). I'm not sure about the version number 'cause A minor update enhancing GPU performance and fixing bugs was received earlier today.
