Ibanezer88 , via OnePlus 7T , Oct 14, 2019 : OnePlus 7T ambient display - Tap to wake and Pick to wake not working . I checked the previous threads and they are all marked closed . These functions were working for 3 days ans now it stopped completely . This kinda disappointing since the phone is just few days old . I have restarted , factory reset the phone multiple times but still the same issue . the older threads spoke about dialling *#808# and recalibrate the proximity sensor but sadly *#808# has been disabled by One plus .
