For hardware defects, https://www.realme.com/eu/legal/repair-service is recommended and for software probs - such as fingerprint pp - it is necessary to consult Android experts .
Cable or charger?
VOOC is from Oppo (same company) -> search for VOOC at digitec...
(X2Pro max speed is 50W -> if you want fast charging, you have to take 50W+ VOOC).
Digitec does not carry any protective covers or films in its range for the realme X2 Pro. I have also already searched for it in vain :)
But a protective cover is included and a protective film is already mounted. It is nicely mounted and the protection is sufficient.
Esons.ch has 2 protective covers and 1 display film on offer.
