There is no problem with the phone except that the upper touch glass is slightly cracked due to a drop, causing a slight gap on the side, but it works without any issues. No repair work has been done on the mobile, you can show it to a technician and check. Only the device, and as security, a photocopy of a National ID card or whatever you prefer can be provided. The phone is very good, fast, and the battery lasts all day long.
