I am sick so I am selling the phone in my hand, there is no problem I have been using it for a long time, as security you can take a photocopy of NID card, you cannot make a video on the phone and take my word, if necessary you can take a picture with my writing on a government stamp, and even if you want you can come to my house and sit at home and have a cup of tea and not take the phone,
