I am using HTC 620g from last few months and the experience is like hell.
This phone is so slow that you cant even imagine.Camera quality is average and sound is not at all good, I got the speakers repaired 2 times.But one thing I will must say that durability is very good.This phone is fallen multiple times but it didnt got a single scracg.Battery backup is very very poor, HTC should provide 2-3 more batteries with this phone.Everytime the phone is on charging mode.Overall its a waste of money to buy this phone.I do not recommened anyone to the this phone.
