Replacing the back glass on an iPhone 12 is not as simple as swapping out a cracked screen. Apple designed the iPhone 12 series with MagSafe magnets and a wireless charging coil attached to the back glass, which makes the process more complex. The only way to replace the iPhone 12 back glass is by removing the adhesive, magnets, and coil before installing a new panel.
This repair demands care because the components sit close to the camera and charging system. Using the wrong method can damage the coil or cause the magnets to shift, which affects MagSafe alignment. Because of this, many turn to an authorized Apple service provider, but skilled technicians can complete the job with the right tools.
Anyone considering this repair should know the steps involve heating or laser tools to loosen adhesive, removing the coil, and reattaching the magnet array before sealing the new glass. The process is detailed and precise, but it restores both the look and function of the iPhone 12, iPhone 12 Mini, and iPhone 12 Pro.
🔧 Tools & Materials Needed
- Replacement back glass (specific to iPhone 12)
- Heat gun or hair dryer (to soften adhesive)
- Suction cup
- Plastic prying tools or guitar picks
- Safety glasses & gloves (for glass shards)
- Isopropyl alcohol (90%+) & lint-free cloth

🛠️ Step-by-Step Instructions
Step 1: Power Off the iPhone
Hold the side button + volume button → slide to power off.
Step 2: Heat the Back Glass
- Use a heat gun or hair dryer on medium heat.
- Warm the edges of the back glass for 2–3 minutes to soften the adhesive.
- Do not overheat (keep below ~80°C / 176°F).
Step 3: Create a Gap
- Place a suction cup near the bottom edge of the back glass.
- Gently pull upward to create a small gap.
- Insert a plastic prying tool or guitar pick into the gap.
Step 4: Separate the Glass
- Slowly slide the prying tool around the edges.
- Reapply heat as needed to keep adhesive soft.
- Work carefully around the camera bump—avoid scratching the lenses.
- Remove broken glass pieces with tweezers (wear gloves for safety).
Step 5: Clean the Frame
- Use isopropyl alcohol and a cloth to remove adhesive residue.
- Ensure the surface is smooth and clean before applying new glass.
Step 6: Apply New Adhesive
- Place pre-cut adhesive strips or apply liquid adhesive around the frame.
- Make sure adhesive covers edges evenly to prevent gaps.
Step 7: Install the New Back Glass
- Align the replacement back glass with the frame.
- Press firmly around the edges to secure it.
- Place the phone under a weight (like a book) for 30–60 minutes to ensure proper bonding.
Step 8: Power On & Test
- Turn the iPhone back on.
- Test wireless charging and camera functions to confirm everything works.
🧾 Extra Tips
- If the glass is severely shattered, applying clear tape before removal helps keep shards together.
- Avoid using too much adhesive—it can seep into components.
