When I fixed the screen of my apple watch SE, the polarized film was damaged I ordered this film by Aliexpress! I tried to install this, but it was not dark enough. Should I use a special glue? Or, should I add an another sheet like OCA film? Please help me!
Most of us just replace the entire display assembly as repairing the assembly is quite hard! Have you looked at just replacing the display assembly as outlined here? Apple Watch SE Screen Replacement.
