G_Saif_Zafar_TMRZ, Jul 20, 2019 : I had a OP3T since Jan 2017. 2 weeks ago I lost it. it was running Android 8. I bought another second hand 3T and updated it to 9.0 immediately and have been experiencing some issues. 1. Touch feels laggy. Input feels delayed. Typing doesn't feel like it used to. 2. Drawing a V turns on flashlight but doesn't turn it off most off the time. it turned off once or twice. 3. Double tap to wake doesn't work most of the time. Sometimes when I reset the setting it works. Do u guys think this is a software issue or phone related.
