There are no problems with the phone. I will change the model so I will sell or exchange it. You can check and test it for as long as you want. The phone was brought from Saudi Arabia. I will provide the original charger and my NID with the phone. I am ready to give any kind of security. If necessary, come and take it from my house. RAM-12GB, ROM-256GB, CAMERA-64+8+5, BACK CAMERA-16. Check Google or call to know details.
