My phone is working great on JB 4.3. I'm not in a rush to change that.

I actually hadn't heard the sd card thing until you mentioned it. Google showed me more details:
Android KitKat Blocks Some Access to Micro SD Cards
Take a LOT of time to really read about the very major
SD card issue that can, for those of us who are unrooted, dramatically change how you can (or can't) utilize your SD card. Check out numerous threads on
XDA about this problem, which seems to have fix options for root, but no fix for unrooted phones.
Basically, from what I've gathered, 4.4 removes permissions from 3rd-party apps (the apps downloaded from any of the markets) to store data on external SD. I believe it also inhibits the ability of your apps to retrieve or modify data on external SD. The other issue is that most of the file managers cannot skirt this problem, or access external SD, and can no longer move folders to and from external SD (actually, I was not able to visualize SD at all on FX or on WiFi xfer.) I also understand (and just confirmed myself) that the ES file manager seems to partially workaround this problem and can access the external SD. I do believe there are still limitations on moving or renaming folders from within the system.
The method that seems to be the only way to bypass this google-directed blockade is to manage your files via USB on your PC. (This will not work on a wireless file manager like Airdroid.) I can confirm that this works as I did so via USB.
I found that all of my 3rd party apps were gone after the update, but more importantly, after re-installing them, the data files had also been wiped. The only apps which have maintained the permissions needed to utilize SD and access all files are pre-installed apps, such as "My Files".
I've lost a LOT of crucial data, even data previously on dropbox. I also found that I was not able to upload files from SD onto dropbox.
Read this blog for many more details, and also note that apparently this permission restriction had not been on the 4.4 changelog.
I, personally, resent having google- and samsung-imposed restraints enforced on how I use my device. If I wanted these types of restrictions I would have bought an iphone. One of the reasons I upgraded to the S4 was because it gave the flexibility of installing and storing on an external SD; now, aftermarket, the S4 warranty has essentially been voided -- by
the sellers!
Sorry for the bold letters, and for the rant (just my old activist brain cells making an appearance), but I am
, big time.
I wish I had read this a week ago, before I excitedly dowloaded 4.4; I would never have installed it had I known what so many others have already found out.
