I am ill so I am selling the phone in my hand, there are no problems, I have been using it for a long time, as security you can take a photocopy of NID card, you cannot take my words by recording a video on the phone, if necessary you can take my written photo on a government stamp, and even if you want you cannot come to my house and sit at home to drink a cup of tea and take the phone,
