Step 1 | Scrape off the old adhesive
Be careful when scraping the frame and back panel — risk of damaging camera sensors, spring contacts, and graphite film.
- Use the flat end of a spudger or your fingernail to scrape off old adhesive from the frame and back panel.
Step 2 | Remove the remaining adhesive
Apply a few drops of high-concentration (90% or higher) isopropyl alcohol to any remaining adhesive.
- Use a microfiber cloth to remove the remaining adhesive.
- If still having trouble, apply a few drops of alcohol and scrape with a spudger.
Step 3 | Orient the adhesive
Place the new adhesive onto the back panel, using the camera cutout as a reference for its correct position.
Step 4 | Remove the adhesive liner
Remove the large rectangular liner by peeling it away.
The exposed adhesive is ready to attach to the back panel.
Step 5 | Apply the adhesive
Misaligned adhesive can lead to an improper seal.
- Lay down the adhesive with the connector cable threaded through the camera cutout.
- Press down firmly around the perimeter to secure the adhesive.
The adhesive is very sticky; once it touches the back panel, repositioning is not possible.
Step 6
Remove any remaining liners from the adhesive using the pull tabs.
Step 7
The adhesive is exposed and very sticky — handle with care.
- Continue reassembly according to your phone's repair guide.
- Prevent the back panel cable from touching the adhesive during assembly.
Return to this guide before securing the back panel.
Step 8
Align the back panel with the phone's back, then place it down.
- Firmly press the back panel into place along its entire edge for at least one minute.
