I have apps such as Any.DO and AK Notepad installed in My Samsung Galaxy Y Android 2.3.6 phone. I have tried Titanium Backup and App 2 SD (move app to SD) but still not able to move these apps to the SD card at all. What's wrong? Can someone help me out here?
An app must explicitly support App2SD, or you cannot move it to the card. There are several reasons why an app might not support it:
As the sdcard would be unaccessible when connecting to a computer, both things would "crash" (as they could no longer access their data etc.). Of course there's always the possibility the developer simply didn't care -- in which case you should contact him and ask.
