iphone screen replacement is the process of fixing a broken, cracked, or not-working screen on your iPhone. If your display has lines, black spots, touch problems, or glass damage, changing the screen can make your phone look and work like new again. A technician removes the damaged screen and installs a new one carefully so the touch, colors, and brightness work properly. You can get it done at an Apple service center or a trusted local repair shop. Screen replacement is faster and cheaper than buying a new phone, and most repairs are done the same day, so you can start using your iPhone again without long waiting.
