The only issue with the phone is that its upper touch panel has been replaced. There is a slight amount of glue on the side from when the touch panel was removed. Actually, since it was a trusted attachment, some glue remained when opening it, but no worries. It has 2GB RAM, 64GB ROM, and 4GB virtual RAM. Other than that, there are no problems at all. The 5000mAh battery backup is very good.
