I love my 625 Lumia I have had it for 2 years no problems till recently 1 month before warranty ended. It started having all sorts of problems and hardly any sound. Microsoft said send to be repaired . They fixed it and now is great again but they charged me 5000rs that is a bit tough when under warranty they put in new battery and a microphone the repairer said it was faulty.
This is the one you cant put in a new battery you have to send it away to have it put in
