There are no films or bulletproof glass that come close to being usable for this phone. With everything you have limitations or it looks shabby, I've already tried a few things (also from Germany) and just threw money out the window.

However, according to the Huawei support team, the glass is very resistant and abrasion-proof, which is why I decided not to use a screen protector. A good cover (impact protection) is sufficient.

I hope I was able to help a little. I was also "horribly" annoyed. This was the first and last mobile phone with an "edge display".
