The phone's display has been changed and an original display has been installed. The volume button line needs to be operated via an app. The SIM guard is slightly broken but it doesn't cause any problems. Everything else is fine. It has been used roughly, so there are some marks on the 4 corners of the phone. The phone is completely smooth, you can check everything. It comes with an original oraimo charger. I have a picture of the cash memo. No hidden problems.
