The phone is good, but it fell, and the glass above the display is cracked, and the SIM tray is slightly loose. It will cost 200 taka to fix; if you buy it, I will get it fixed for you. 4GB RAM, 64GB ROM, memory card supported. I haven't experienced any lag. If anyone urgently needs a decent phone at a low price, you can take it. I have used it for a long time; it's a good phone.
