I have bought a new android phone (Samsung GT-S7710) with a new android system. It has a lot of useful features and lots of flaws caused by too hasty development.
One of these flaws is the lock screen. On my android version (4.1.2), the lock screen is unlocked by sliding anywhere to any direction. This often happens in my pocket and causes lot of problems (contacts getting deleted, random calls and so on).
I still don't understand what was the programmer responsible for that thinking about. It's just as ridiculous as having a keyboard phone that says "Press any key to unlock!".
Of course, I could set up a password. The thing is, that my previous phone has returned to me, because there was no password and the man who found it could contact my relatives.
I actually see no reason to have a password in my phone anyway. I often borrow it to other people and password is just annoying.
So is there some lock-screen patch? Can I install some application that handles screen locking right? Can Android be updated to a fixed version? I don't want to root my phone though.
For those who don't get it from the above: How can I lock my screen so that it won't unlock in my pocket easily? I'm looking for a complete solution.
Oh and also, the top bar is not locked at all. It keeps turning on Mobile data and wasting my money (for me, mobile data is an expensive thing I want always turned off)
