If your iPhone 12 screen is cracked, unresponsive or has display issues, you need a screen replacement. This guide covers DIY steps, professional and repair options, and certain key considerations to help you decide the best approach.
Why would you need to replace your iPhone 12 screen?
- If the glass is cracked or shattered, physical damage from drops or impacts causes cracks to appear on the screen.
- Unresponsive touchscreens or issues with the digitisers require professional intervention. Flickering or discolouration is caused by OLED panel defects or software glitches.
- A black display screen could be due to cable damage, even if the phone is powered on.
Tools required for a DIY replacement
- A Pentalobe screwdriver for removing the bottom screws.
- Y000 screwdriver for internal screws.
- Heating tool or hair dryer to soften the adhesive around the screen edges.
- A suction cup or a prying tool to lift the screen without damaging the cables.
