i don't know why, but in recent 3 day, my memory card goes crazy! and sometimes (3 times in a day) notify me : "damaged memory card, do you want to format it?"
and when i format sd card, some applications corrupted and can't run, because it says : "this application not installed in your phone!"
is there a way to disable or disallow android from installing or storing any data related to application installed on phone?
phone Specs:

  • model : samsung GT-I9100G
  • Build number : Gingerbread.JPKK1
  • android version : 2.3.6

What you describe is a mix of multiple problems. First, your apps becoming "unavailable" is most likely due to Apps2SD being used, and you installed those on your SD card. See:

Second thing is your card itself (hardware, the "thing you put inside your device"). If it goes broke that often, this rises some hardware related questions. Most likely possibilities:

  1. Your card is broken
  2. Your devices card adapter is broken
  3. Something with your card controller is broken

You can check 1. easily in different ways:

A. check whether your card causes problems in other devices
B. check whether other cards cause the same problems with your SGS

If (A but not B) => use a new card (case 1.)
If (B but not A) => have your device checked (for either 2. or 3.). Hopefully you've got some warranty left.

  • Not that I know of. Never heard of class A..C -- just numeric values. There's the higher the faster (and as a side effect, often less power hungry).

  • Yap,got it. Now number 2; why when i install app in phone storage, i see some data related to that application saved in sd card?! A directory named android.

  • That might be app data (data the app stores when used). And class 2 is ancient and slow. Even class 4 is quite slow. If you buy a new one, get a higher class (not a must, but a strong recommendation) -- class 6 or higher I'd say. I personally would go below that.

  • it's so bad. in galaxy sII 16Gb, you can install applications in 2Gb space, and other 11Gb is for your books or media. i want it, why just 2Gb! it's very low! i had googled it and no response, other users face this problem and no one solve this. forum moderators say that it's good think for stability ,but i don't!
