Instructions for gluing (for B-7000):

1. Apply the glue in a thin layer on the edge of the display (not on the glass itself!).
2. Apply the new glass carefully, starting at the top, and press it.
3. Remove excess glue with a napkin soaked in alcohol.
4. Place the phone under a press (for example, between two books) for 12-24 hours.

1. Apply the glue on the display and distribute it evenly using a scotch mask.
2. Attach the glass and remove the bubbles with a vacuum pump (or manually, squeezing them from the center to the edges).
3. Illuminate with a UV lamp (365 nm) for 5-10 minutes for polymerization.
