Well, I don't want to hijack the poor guy's thread with geeky arguments, but that is an even weaker excuse than the fear of rogue apps story. Suppose a user does choose to put his bank account and credit card info on an unencrypted sd card? Then he would have it in his pockets along with his credit card and checkbook?
I don't really agree with Google's position, I'm merely regurgitating it. I do understand their position though. While people should be aware of their personal data, most don't bother with the specifics, and leave themselves vulnerable out of laziness and ignorance. The downside of this policy is that with previous versions of Android the user could move huge apps - games mostly, like Asphalt 8 or GTA 4 take up a ton of space - but 4.4 KitKat doesn't allow this. I've kept my tablet (LG G Pad 8.3) on 4.2 even though there's a 4.4 update, for precisely this reason (with root there's workarounds, but I've been too lazy to do it). Getting back to Google, they're a for-profit company like any other. Faith in their services is paramount, just like any other company. It's in their best interest to be as secure and safe as they can. Thus, they've limited external SD functionality for security reasons..
As I recall you know a lot more about Android than I do. Can we figure out how to help Mr. Omega get his new phones working?
With Android 4.4 Kit Kat, you're able to store pics on internal storage or external storage (if it exists) at the user's choosing. Every phone is different, and they also differ between carriers. Anthony hasn't said what phones he's using, nor which carrier he's with. This matters. For example, a Samsung Galaxy S5 from T-Mobile is very different from one from Verizon, despite being the "same" phone. If we want to delve deeper into certain possibilities (which are likely extremely complicated and warranty-voiding) I would need more information.
Anthony, I need to know what phones you bought, and what provider you're with. In certain respects, 4.4 Kit Kat is very different from previous versions, and I'm not just talking about features. I don't claim to know everything (not by a long shot), but I do know a lot, and I know where to look for what I don't know.
