Step 1 — Prepare the Phone

Power off your iPhone 12 completely.
Remove the SIM tray to avoid accidental damage during the repair.

---

Step 2 — Heat the Cracked Lens

Use a heat gun or hairdryer to gently apply heat around the cracked lens. This softens the adhesive holding the lens in place.
Move the heat source slowly around the edges, keeping it at a safe distance to avoid damaging the surrounding camera components.

---

Step 3 — Remove the Cracked Lens

Once the adhesive softens, carefully use a tweezer or a sharp plastic tool to lift the cracked pieces.
Take your time and work slowly to avoid scratching the camera frame.

After removing the lens, clean the surface and edges using a small brush.
Make sure there are no dust particles or glue remnants, as these can affect the new lens installation.

---

Step 4 — Apply Lens Adhesive

Take the pre-cut lens ring adhesive and place it precisely on the camera frame.
Ensure it fits perfectly and sticks well to the frame. This step is crucial to secure the new lens and maintain protection.

---

Step 5 — Install the New Camera Lens

Place the new camera lens carefully onto the adhesive.
Avoid touching the rear side of the lens with your fingers to prevent fingerprints.

Gently press down the lens to make sure it adheres evenly to the frame.
If you are replacing multiple lenses, repeat the same steps for each lens.

---

Step 6 — Final Check

After installation, check that the lens is secure and flush with the camera frame.
Clean the lens surface with a microfiber cloth to remove any fingerprints or dust.

---

Step 7 — Test the Camera

Power on the iPhone and test the camera. Ensure it focuses properly, captures clear images, and that no dust or light leaks are visible.
