I am coming from a g2/g3/g4 device. The GPS on the G4 was simply Amazing, I could lock satellites indoors with 20 to 30 ft accuracy. g5 Cannot lock indoors, accuracy drifts sometimes up to 150-200 ft. It also lags/hangsup under Open Sky occasionally. Is anyone else experiencing GPS difficulties? I've been using "GPS Test" and "GPS status" apps to monitor and try to increase my indoor... Please let me know
