No, the interface designer said that's why he doesn't wish to support them. The people who write the code have given a long and detailed explanation about why they are not supported. I've posted, and reposted it. Nobody cares enough to remember.
Google said all along that it was a bad idea, and they would like to remove it.
Only people who don't understand how mount points and file systems work under Linux think SD cards are an advantage.
Some of us have said form the beginning that SD card support (especially apps 2 SD) was a horrible idea. Having to read countless threads like this when OEMs realize it and stop using them is a big part of the reason why. At a technical, OS level, SD cards are horrible. They can't be used as hardcoded storage because they can be removed. They can't have a secure filesystem because they need to be readable on Windows computers. They cause app developers to code for iOS first because OEMs don't have the skill or desire to implement them correctly. They put money directly in Microsoft's pocket with each device sold.
The good news is that Samsung won't ever be able to figure out how to implement them without spending money in engineering, and phones running 4.2 and higher just won't have them. Now if they would only get rid of the menu button so Android app development could advance.
