Fixed price, please do not bargain with absurd prices. The set is completely fresh with no issues. I have used it for 6 months. The set was bought on installments and there is still one installment remaining. The date to pay the installment is the 24th of this current month. Whoever buys this set, I will pay off the installment. RAM is 4.1 GB, ROM is 64 GB. The 5200 battery backup is very good and can be used for two days. The box and charger are lost, but all kinds of documents will be provided.
