There are no problems with the phone, the battery backup is good. I need money urgently, so I am selling it. The phone has been used by one person and is still like new. I don't have the phone's papers, but I can provide the charger I bought from the shop as the original one was lost. For security, I can provide a photocopy of my NID card. If you want to buy the phone, you have to come to the location: Savar Model Mosque.
