FAQ

Galaxy S21 Ultra repair questions

Why does my S21 Ultra have a green line?

It usually points to a fault inside the AMOLED panel. Replacing the screen assembly is the reliable fix.

Why is the screen fitted with the frame?

The curved panel is bonded to the frame; a pre-fitted assembly gives a better fit and seal.
