Purchased lumia 710 on 27.6.2013.Now it has two problems- 1)device charging port has become loose and frequently stops charging 2)you can not talk using ear phone .voice can be received but does not go out, tested with other earphones same condition.i.e problem in device Showed it to nokia care centre at sector 10 noida UP IndiaM/S Mannat telecom .Phone checked by service engineer says USB charging port broken and returns the phone after completely damaging the port.Now it can not be charged at all while previously I was able to charge it. They refuse to repair both the problems saying warranty is void. Now their person breaks the port and then claims repair charge of Rs. 3500/-which is highly unfair.This is common manufacturing defect in nokia 710 as can be seen from online complaints.The phone has never suffered even slightest damage and only been used with nokia charger supplied with it. The service engineer from nokia completely damages the charging pin and then claims warranty is void as pin is damaged.New method discovered by nokia to cheat people.
