Introduction:
A cracked or delaminated Samsung S21 Ultra/S20 Ultra screen doesn’t mean you need a full replacement. The right Optically Clear Adhesive (OCA) can restore your display to like-new condition—if you choose the correct thickness and quality.
Why 125µm OCA is Perfect for Samsung Ultra Models

- Maintains 98%+ light transmission for vibrant colors and sharpness.
- Durability & Scratch Resistance
- UV-resistant properties prevent yellowing over time.

Installation Tips for Best Results
