I am fairly new to Android, but what I read is that you cannot put apps on the SD expansion memory, as they will not run from it. I think this is standard with 4.1 and 4.2, at least. The SD memory seems to be for storing data only, like movies, documents, images, music, etc.
That's not my experience. I have used other tablets running 4.3 (which is what I'm running on my Dell Venue 7 now) and I could move any non-default apps (apps I downloaded and installed) to my external SD Card. After clicking Settings, then Apps, there should be a button that says "move to sd card". If it isn't greyed out, you can move the app and it runs without a problem. I think it's ridiculous that this option isn't available on a tablet that has external memory. It was available on my previous table, the Nexus 7, which didn't have an external SD card. I'm inserting an image of what the screen with this option looks like:
WOW, this is great news, and I agree that it didn't make sense that the system would not allow you store and run from external memory. You mentioned it could be greyed out. Do you know what types of apps are prevented from being moved? Also, what happens when you remove the SD card? Do the icons for those apps disappear from the display?
I have to check my current tablet (I had to return the Dell Venue 8, long story) to see if that works with it (it is running 4.1.2).
Thanks for your response.
The problem is even if "move to sdcard" is an available option in most cases it still isn't saving to your external sdcard.
The file system is:
Sdcard ext. or sometimes sdcard2
So if the option is there to move to sdcard it is still just a partition in the on board storage and not the external card. So the option is kind of pointless. It is just moving your apps to another portion of the on board storage. This started with the jump somewhere between Froyo and Honeycomb. With froyo you actually could save apps to the external card.
If apps can truly be moved to the external card there would be an easy test to see if this is actually working now. IF you have this option on a device Save an app to the sdcard, then remove the card, then try to open the app. If it opens it isn't really on the external card.
Android versions 4.1 and 4.2.2 have three memory partitions: internal memory, sd memory and external sd memory(a sd card you buy). Not being able to move apps to the sd card is an Android 4.1 and 4.2.2 restriction. The reason for this is because those versions are rooted. If you can find a unroot program in Google Play simple enough, then you can unroot your device which then opens up the ability to move apps to external sd instead of the internal memory or the devices sd memory. The program (app) most known for this issue is Superuser which is free and available in Google Play appstore. Good Luck...I'm having the same problem in my generic tablet. I am thinking on going with a Dell Venue 8 though.
