My above mobile is useless for me, i am facing following problem:-
1. Over heatin problem it is warm up within 1-2 min. Of talk.
2. It is unable to catch the network whereas the same sim in another mobile at the same place the network is superb.
3. I already send this device at service center 4-5 times but nothing progress they are hand over with remark that the device is ok but when i am using sim in it, it is not work at all. Whereas the same sim in other device working very well and the signal is fine.
