Rajesh1verma anishchandran try backup your data then reset if possible. If something is wrong then it will solve. If this doesn’t work you can reach the service center
Jay yeahhh, I faced this issue. but I did restart then I dont face it anymore. idk what fixed it. I have ph1 as well.
christo_reese it happens also on phone 2, then again, my xiaomi did the same also when using tap to show lock screen. My the last resort is to select lift to show lock screen. Works like a charm every time.
