The phone's Wi-Fi, data, and SIM connection are all working fine, but the battery health is 75%. Due to the battery swelling, the back shell is slightly detached, and there is a thin line on the display which appeared because it was not used. Other than that, there are no problems with the phone. You can check it as much as you want. If you buy it, the price can be slightly reduced. Please do not bargain unnecessarily.
