Experience with Back Market top, I recommend it. As far as the phone is concerned, I'm sorry that after a year of use, the phone sometimes freezes and I have to wait even 5-10 minutes before I can turn it off and on again (it happens more or less once or twice a month).
Also, the camera doesn't work as well as before, sometimes it struggles to focus and the quality doesn't seem to be the 48mp of the early days. But after only 1.5 years, I'd hate to have to change it.
