Update: Handset gets start up but the on off button doesnt work, the moment battery is inserted handset gets on by itself, and speakers and mike arent working and screen keeps splashing on off types.
Wifi doesnt get connected but data works.A friend who also does repairings and all for electronics mobiles suggested me to keep the handset and battery under some heat, as rain going on here, asked to keep it under lamp few inches away but the way that heat from the bulb works and moisture goes away.If it works then it would else dead.
MS@ you want a dual sim handset, as both the grand2 as well as htc 816 are dual sim handsets, and you were not satisfied with the grand you brought firstly then why grand 2.Better go for nexus 5 or if you can go for note 3.
