Among popular smartphone screens, OLED is different from LCD, the well-known represent-ative OLED is Samsung SUPER AMOLED. It is with brilliant sharp colors, but it seems so fragile as you accidentally drop your phone on the ground,you will probably get a shattered screen.
To fix this headache, it is very difficult even for repair stores. Refer to iFixit guide, Samsung Galaxy S7 edge Repairability Score is 3 out of 10 (10 is easiest to repair). Because the S7 edge phone and screen use tons of adhesive to attach the screen, glass lens and the frame, meaning when anyone breaks one of them all three need to be replaced. Replacing the glass only is a big challenge even for professionals.
Today, REWA Lab is bringing the success to the curved OLED Glass only repair, aiming to make the repairing of cracked screen clear and easier for professional repairman. Below are the detailed instructions for Samsung Galaxy S7 edge screen repair.

Make sure the display and touch functions both work well on the glass-cracked screen.
Firstly, we need to remove the screen from middle frame of the phone. Use Pry Piece, 530 cleaner and Heat Platform to separate the LCD and frame preliminarily, then separate it completely with Frame Separator.
Samsung SuperAMOLED screen separating is different from iPhone screen repair, here we use Frozen Separator to disable the glue and a plastic Pry Piece to help.
Put screen into Frozen Separator, freezing 30s, then separate the OLED from glass.
With the help of 8333 remover and N-hexane, clean the glue residue on the OLED.
Use a Manual OCA Film Laminating Roller to laminate OCA sheet onto OLED.
Put it into Bubble Removing Machine for 15 minutes. Make sure the OCA is bubble free on OLED.
Align the front glass with OLED, then laminate the glass and OLED with help of Vacuum Glass Laminating Machine.
Put it into Bubble Removing Machine again for 15 minutes. Make it bubble free after glass laminated.
