Recently purchased DOOGEE S60 has some issues from day one as its unable to hold wifi connection and switching to mobile data almost immediately and every single time. Also noticed that brightness and airplane mode do not stay on longer than a few seconds when turned on. It always goes back to Mobile data which has now drained almost half of my monthly allowance in just 3 days.
