Hello everyone.
I just got my Samsung Galaxy S4 GT-l9505 and updated to android version 4.2.2. I am suffering like how you guys are with this "Unable to read SD Card" or "SD Card is removed" problem (welcome to the club?). I also own a tablet, Asus TF300; android version 4.1.1. There are no any problem with reading or whatsoever, it works fine on my tablet.
After some research on other forums, I am highly convinced that this problem is
1) due to this current version of android; 4.2.2. (most likely)
or
2) due to manufacturing fault of samsung S4 that leads to having problems with SD cards; especially 32/64 GB
Edit: I'm currently trying with a old 8GB SD card. I will update how it goes.
I guess I'll follow this forum and topic awhile.
Cheers,
Kelvin
