If your iPhone 13 screen is cracked, not responding to touch, or not showing a picture when your phone is powered on, use this repair guide to restore your iPhone to working order with a new screen, a.k.a. display assembly.
Use a hair dryer or a heat gun to heat the bottom edge of the iPhone until the screen is slightly too hot to touch.
Never leave your heat gun in one spot for an extended period of time.
If you're using a single suction handle, apply it to the bottom edge of the phone, while avoiding the very edge of the glass.
Heat the right edge of the iPhone (the edge with the power button) until the screen is slightly too hot to touch.
Heat the top edge of the iPhone until the screen is slightly too hot to touch.
Heat the left edge of the iPhone until the screen is slightly too hot to touch.
There are delicate cables along the left edge of your iPhone. Don't insert your pick deeper than 2 mm here, as you may damage the cables.
Remove the cover.
Use tweezers, or your fingers, to move the proximity sensor cable away from the screen.
