    my phone is samsung S2-VER-4.0.3 MODEL-gt-I9100DXLPA,can i use this firmware in malaysia region(…???

  • hong

    do you have any apps recommend as i really have tried all the option

  • See under Accessibility and Developer Options in Settings for a solution.

  • hong

    It will vibrate when i press the ‘back’ button and the ‘menu’ button and when i move the position of the apps
    below is my setting :

  • You mean vibration is turned on by default? May I know the places where you feel it?
    See under Accessibility and Developer Options in Settings. I remember the haptic feed back option being there on my S2 (I do not have it now).

  • hong

    i know it is under haptic feedback but mine i dont have the setting, so do you know is there any software can block the vibration of the phone?

  • Go to Settings> Sound.

  • hong

    may I know where is the vibration setting??I have searched all the phone setting and i cant get it

  • I just meant that you should try a data/factory reset via stock recovery by pressing the Volume Up+Home+Power keys. This might fix your problem.

  • hong

    you mean i have to factory reset before install jelly bean?but now i have update to jelly bean already so how am i going to do next?

    by the way, what is the function of CWM??and is it same with recovery function which I get into in by pressing volume UP + HOME button + POWER button?

  • Did you factory reset your phone? If not follow the steps given under Method 1 here:

    Do not forget to backup all your data before doing that.

  • hong

    I faced a problem which is when i have set the Home wallpaper to my one, but after i have restart my phone then it will be changed back to the original Home wallpaper, do you know why?
