Alhamdulillah, the phone is completely brand new. I can provide the cash memo, mobile documents, everything. I can even take the mobile to the exact shop from where I bought it.
There are no issues whatsoever with the phone; check it a thousand times and take it only if you like it.
Otherwise, no worries. I am selling it because I want to buy an iPhone. Whoever takes this phone will benefit greatly, Inshallah.
I have been using it for about four months.
