The phone's RAM is 4 GB, ROM is 64 GB. Anyone can exchange if they want. The phone's display has a green line which is clearly visible in the picture, other than that there is no problem, you can check and use it as long as you want, there is not even a dot of problem other than the display, price is mostly fixed, can be reduced a bit, my dad is ill and I urgently need money so I am selling the phone in my hand.
