Sorry to ask what is probably an old question, but can someone give me a quick explanation of what is meant by the comment I put in the thread title? I am currently running 4.3 on my S4 and have not had trouble with my SD card. Does this just refer to how you can't install apps there anymore, or is there something more annoying going on that I haven't yet stumbled upon? I googled this question a couple of weeks ago and didn't find anything so I decided to ask... I expect to get the 4.4 update this week based on what others are saying, and want to be sure I'm prepared for anything I'll need to work around. I use my SD card for photo storage and downloaded documents. Thanks!
