I have a dual SIM mt6589 based Android 4.2.1 phone, and I have no idea where the apps are getting installed.

My phone has an Internal SD card(built in), An External SD card and something called Phone Storage(/data ??)

Anyway the apps are supposed to be saved to my External SD but they get saved to Phone Storage.

Also the option move to External SD card is greyed out(It was available before!!). My vold.fstab file

dev_mount sdcard /storage/sdcard0 emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-msdc.0/mmc_host
dev_mount sdcard2 /storage/sdcard1 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.1/mmc_host

  • Ah @Izzy It answers my question, hmm looks like I can't move half the apps from my Internal Storage -_-. Also What do I do with the question ?

  • usually apps get installed to Internal SD(with android 4.1.2) but after updating to 4.2.1, I can install to only Phone Storage

  • As your question might provide a place-holder to already existing details, I composed a short answer you might want to accept/upvote, so other "searchers" can find their way and follow up. The issue from your previous comment you'll need to address to your manufacturer/ROM baker: They have disabled that functionality, Android itself still supports it (you're in good company with that, seems a few manufacturer decided to do the same).

The answer to your re-phrased question can be found in the tag-wiki. In short:

  • App2SD cannot move the entire app to SDCard, there are always things remaining in phone storage (e.g. data, Dalvik cache, and some more)
  • There are alternative methods moving more stuff, such as e.g. or Data2SD

For details, please see the linked tag-wiki.

  • Also there seems to be a way to extend the Phone Storage forum.xda-developers.com/showthread.php?t=2296230

  • Not really -- it can't take stuff from nothing. That tool simply changes partitioning, taking space away from the internal SDCard and adding it to "phone storage".
