Same summary

The My Screen protector DIAMOND GLASS Full Glue EDGE 3D tempered glass is designed for Samsung Galaxy S21 FE users who want discreet but reliable screen protection. The product is best suited for people with an active lifestyle or anyone who uses their phone outdoors frequently, as tempered glass absorbs shocks and prevents scratches better than conventional films. The 3D edges make the protection more complete and maintain the feeling of natural sliding on the screen, while not significantly affecting the responsiveness of the screen. If you are looking for minimalist protection or want a thinner thickness, you will notice a slightly more robust feel with the glass, but this is a compromise for greater device safety.

Answers to frequently asked questions

Does this screen protector cover the entire screen including the curved edges?

Yes, DIAMOND GLASS Full Glue EDGE 3D provides full coverage of the Samsung Galaxy S21 FE screen, including curved edges, which means better protection against bumps and scratches.

Does the touch sensation or responsiveness of the screen change after installing the glass?

The feel of sliding across the screen remains natural, and the touch response is largely unchanged. Some minimal difference in feel is a natural consequence of the additional layer of tempered glass, but this does not interfere with normal use of the phone.

Does this tempered glass prevent air bubbles from forming when gluing?

The glass has a full-surface adhesive ("full glue"), which allows for a more even installation and reduces the possibility of air bubbles when properly installed on a clean screen.

Is the glass also suitable for use with phone cases?

It is designed to be compatible with most standard cases for the Samsung Galaxy S21 FE. For thicker or very rigid cases, we recommend checking that the case does not press against the edges of the glass before installation.

When is it recommended to replace the protective glass?

It is recommended to replace the protective glass as soon as you notice visible cracks or damage, as its protective function is then reduced.
