The hardened protective glass has the highest level of scratch protection (9H).

Useful information to install glass film:

- Use the wet wipe before installation, degreasing the surface with all the dirt, making sure that dust or lint does not get on the display
- then delete the display dry to dry or lub
- Carefully pull off the foil layer 1, which can be discarded. We will not need it anymore
- grab the bottle with both hands at the four corners and paste exactly on the device
- We don't accidentally hold this "sticky" surface, pay attention to cutting the speaker or buttons in the correct location, or run parallel to the pages
- let the appliance be carefully
- If you have been able to fit it accurately, press the bottle slightly with a new one in the middle that will spread from the middle and stick to the display
- possible air bubbles (provided if no dust or lint is below) are absorbed within 1-2 days
