The phone's motherboard had a short circuit. I got it fixed once and after running it for 6/7 months, the problem occurred again. When I took it to the technician, he said it would cost a bit more to repair. Also, the display is broken now. So I didn't get it fixed anymore. It is as it is. Now if anyone needs it, those who buy damaged motherboard phones can take it. Casing, battery, camera are all good. Location, Satkhira Sadar.
