[Q] Galaxy Grand Duos update to 4.2.2 differences topic

Hi,

I updated the Samsung firmware/software (or whatever it's called) today from 4.1.2 to 4.2.2 Kernel 3.0.31-2212686.

I have noticed a couple of niggling little differences in the operation of my phone and am wondering how to change these back to the way they were BEFORE I updated.

1) When typing my PIN code on the lock screen, the phone vibrates. It never used to. How do I change it back?

2) When I receive a text message, I now get a preview of the message on my lock screen. I never used to get those either. How do I change it back?

Any help would be much appreciated.

Thanks.
