IPhone 8 lock screen can't swipe on lock screen
Hello, I am currently using IPhone 8 ios 11.2.6
The problem of this phone is after I bought for a few weeks, it had this problem which I cant swipe left or right to camera accessor widget very often. It even happen when I just done reformat the phone and without downloading any third party apps the problem still exist. I had try reformat and restore the phone, force restart the phone, update to the latest version. Still can't fix the problem.
I even took it to the service center and they can't identify the problem.
Can anyone help me?
Thank you so much.
