Glass Replacement on Samsung Galaxy A21s
The Samsung Galaxy A21s is still popular with users looking for a reliable phone with a large 6.5-inch screen. When the glass is damaged, that does not mean you have to replace the whole display — OCA lamination makes it possible to replace only the top glass while fully preserving the original PLS TFT panel and all the sensors beneath it.
What OCA Lamination Involves
Glass replacement on the Galaxy A21s requires precision and experience because sensitive components sit beneath the glass:
- The fingerprint sensor on the back of the housing makes access easier, but the front sensors require careful separation of the layers
- The proximity and ambient light sensors must remain undamaged while the old glass is removed
- The OCA adhesive is applied under controlled conditions to avoid bubbles and ensure perfect adhesion
The whole procedure takes 3 to 5 hours because it includes separating the glass from the panel, cleaning the surface, applying a new OCA layer and laminating under pressure.
