Udit_041190, Jun 25, 2019 : after using OP 5 since the day it launched now finally bought OP 7pro due to many reasons (mostly because of no notch display and haptic feedback while playing games). no idea what i changed but haptic feedback is not working anymore while playing PUBG and Asphalt. i tried undoing what i did.. nothing worked. need your suggestions here for getting it back on. or if any1 else is facing the same issue as i am.
