Apply a heated iOpener to the bottom edge of the screen for a minute.

Place a suction cup near the bottom edge of the screen, near the USB-C port.

Lift on the suction cup with strong, steady force to create a gap.

Depending on how aged your phone is, this may take significant force. If you are having trouble, apply more heat and try again.

You can also try heating and pulling up a long edge of the phone to gain access.

Insert an opening pick into the gap.
