Honestly, when the Sony 4 was at its peak, I didn't use it much due to my studies. I played it for a while, then stopped until I got a job. I'm still not benefiting from it. You can try it for three days, and if there's any defect, return it and get your money back, to show you that it's a clean device. I'm selling it for 500 (Sold, may God bless the buyer).
