guy's who are having lagging problem just clear complete cache memory, then the phone will work fine really, and also if any one using cleaning apps just delete them. and don't use lock screen which was come with 4.4.2 use 3rd party lock screens. and close the Google location server also. Now your phone will work fine.

What u said was right for you only, not for all.
after 2 months the flap was getting loose and if you take off the back cover frequently it will be also loose than there is chance to water to go in.
Those who using dock charger,drop box for data transfer from PC, etc... still their phone are water resistant.
Sony claims that these phones can get in 1.5 meter of water for 30 minutes but my phone could not resist a bucket of water for even 3-4 seconds. Water has leaked to battery area from back cover.
The exception with Xperia ZR is that its back cover can be removed unlike Xperia Z/Z1. So there are plenty of chances for water to leak inside the phone near battery. But SONY people are not ready to accept the fact.
