Question about Fairphone 3

I bought a

Protective Glass Film 9H Armour Film Display Protection Glass Film

and mounted it, perfect.
I have not found a protective cover for this device.

I don't use any additional protective cover. When I am hiking, I use a waterproof "aLOKSAK". For the FP 3, there are protective films from various manufacturers that fit: "upscreen", "brotect", seen at schutzfolien24.de

When I bought the device, it was equipped with rubber edge protection. I already know this from my previous smartphone and therefore did not buy another cover. However, I had the recommended protective film applied. 1 x Hama Ultra Film S (1 piece) CHF 29.00.
I must add that I leave my new FP3 at home during dangerous activities and take an older device with me.
