I have questions about delta update:

  • Is delta updates world wide?
  • What version of Android work with delta updates?
  • Are all apps supported for delta updates?
  • Is there any work to do to activate this feature?

I ask this question because I can't use this feature and still have to download whole size of app for updates

Delta updates work with every file that have a valid delta file for it to update. The binary delta2exe applies that delta file on your old file and updates it to the newer one.

All you need is that delta file which you can get (and is applied directly) with the app CyanDelta which works for all official releases of CyanogenMod and OmniROM.

If you have the old and the new file you can easily create your own delta file by following the tutorials on how to create delta files: eg. for xDelta

    Then delta updates are not possible. You can only do a delta update if both ends (update server like your manufacturer and your phone ('s software)) support that feature.
