(New) iPhone 15 Back Glass Installation

Use the pointed end of a spudger to press and roll the adhesive until you can grip it with a pair of tweezers.

Use the tweezers to pull the adhesive off of the phone.

Wrap a microfiber or lint-free cloth around the pointed end of a spudger and apply a few drops of high-concentration (greater than 90%) isopropyl alcohol to the cloth.

Wipe in one direction along the perimeter of the frame to clean the adhesive residue.

Wait a few minutes before proceeding to make sure any excess alcohol has evaporated.

Lay the adhesive next to the phone and use features like cutouts for spring contacts and the rear camera to make sure the adhesive is oriented correctly.

Use the pull tab to begin peeling the back liner off the adhesive starting from the bottom, but don't remove the liner all the way.

Hold the liner out of the way and align the adhesive with the bottom edge of the iPhone.

Lay the bottom edge of the adhesive into its recess in the frame, making sure the iPhone's spring contacts are aligned with their cutouts in the liner.

When the adhesive is aligned, use the flat end of a spudger or your finger to press it down firmly along the bottom edge.

Continue peeling the back liner off of the adhesive while pressing the adhesive into place along the edges of the iPhone's frame.

Make sure the liner is aligned properly by checking that all spring contacts and the rear camera are in their cutouts. If they aren't, remove the adhesive and start over with a new sheet.

Use the flat end of a spudger to press the adhesive into place around the perimeter of the frame.

Remove the top adhesive liner.

Prop up the back glass along the right edge of the iPhone, using a box or similar sturdy object to support the screen.

Use the flat end of a spudger or your finger to connect the wireless charging coil press connector, then the battery press connector.

Place the middle connector cover over the wireless charging coil press connector so it slightly overhangs the slot on the logic board for the bottom clip.

Use your finger to press the cover down on the logic board.

While pressing it down, slide the cover upward so both metal clips slot into their spots in the logic board.

Use tweezers to hook the top of the lower connector cover into its slot on the logic board.

Lay the lower connector cover over the press connectors.

Use a tri-point Y000 screwdriver to install the 0.9 mm‑long screw securing the middle connector cover.

Use a tri-point Y000 screwdriver to install the two 1.3 mm‑long screws securing the lower connector cover.

Use tweezers or your fingers to separate the pull tabs at the bottom of the frame, near the charging port.

Remove the narrow liner covering the adhesive along the left and top edges of the frame.

Hold the back glass over the phone without letting it touch the adhesive, so you can access the remaining liners along the right edge of the phone.

Use a pair of tweezers or your fingers to remove the remaing liners along the right edge of the phone.

Lay the back glass straight down onto the frame and press until the clips engage.

Press around the perimeter of the back glass to engage all the clips.

To help the adhesive bond, apply heat to the edges of the back glass using an iOpener, hair dryer, or heat gun until it's hot to the touch.

Firmly press around the perimeter of the back glass. If you have screen vise clamps, use them to strengthen the bond of your new adhesive. If not, keep reading for more ways to secure the back glass.

If you have the box your iPhone came in, take the lid and place it on a flat surface.

Place your iPhone screen-side-up in the lid of your box with the camera bump in its recess.

Find something close to the size of your iPhone, but taller than the sides of the box. Stack it on top of the iPhone, followed by a few heavy objects.

Leave the objects in place for at least thirty minutes. The lighter the objects, the longer they should be left. Ideally, leave them stacked overnight.

Place the iPhone screen-side-down on a soft, flat surface.

Apply tape to the back glass to protect its finish.

Place evenly spaced layers of coins or similarly thick objects on the tape along the edges of the back glass.

Stack them to a consistent height taller than the camera bump.

Stack multiple books or other heavy objects on your iPhone.

Leave the objects in place for at least thirty minutes. The lighter the objects, the longer they should be left. Ideally, leave them stacked overnight.
