[DISCUSSIONS] Why Does The Lens on Z2 always moist up?

So let's start the discussions with Hi :). Im pretty sure many of the Z2 here love to take pictures underwater.But some of the models give moisture on the lens and the PHONE IS 100% IN PERFECT CONDITION. after the action underwater.So why does this happens even when the phone on normal temperature before dipping it under water(Tap water for example). Can anyone explain?

wifi always on

The problem is that i cant get it to turn off,everything is turned off:network notification,scanning always available,keep wifi on during sleep-never.Location also off,disabled most of the stuff under sync-even disabling sync all together didnt help
did factory resets,tried wiping cache in recovery and its still on all the time
any ideas,cos its really frustrating?
and im not using viber :p
