Iphone 7 plus problems
My iphone 7 plus with version 10.3.3 stopped charging on September 9, I complained to apple and got replaced with new device but this new device today (September 18) 2 times hanged.
1st i opened GarageBand and wanted Guided access, screen started flashing with some lines on it (like the old Tv models) but after few seconds I managed to take control by pressing home button.
2nd I installed 1 app and opened it directly from App Store, app worked properly. But when I turned back to App Store from the App it just freezes there. Even by pressing power button it shows the screen with locked sign but not locked screen.
Attached is the screen shot that shows device is locked but showing lock screen and had to force restart.
