The model is Xanon X21. The phone suddenly turned off. I showed it to a technician, and they said it would cost 2500 Taka to fix. I have used it for a year and a half; it comes with the box and cash memo, but no charger. I am buying a new phone, so I won't fix this. If anyone wants to take it, they must take it at their own responsibility. 8 GB RAM, 128 GB ROM.
