Samsung Galaxy A5 2017 SM-A510F

Samsung Galaxy A5 2017 SM-A510F
Gold Color
Lcd Screen was replaced and a new battery fitted.
But was never really used after that.
2 Problems with the phone
Return button does not work and the phone freezes every now and then especially after a phone call.
My guess is the proximity censor is faulty.
Otherwise its a good phone.
I'm just trying to get back what i paid for the new lcd screen and battery.
Phone was in a protective cover since day 1
Please don't buy the phone and give me a bad rating afterwards, I've mentioned the 2 problems and you are buying it as is for parts or to fix.
The protective cover and original box is included but no charger or charging cable.
