I bought a 2014 note 10.1 and the unit itself seems to work great... except for the sd card. At first I thought it was a formatting issue, and after trying to format it on my computer using FATand exFAT and still the unit wouldn't recognize the card. So, even though the card worked on both my Samsung phone and computer, I went and bought a new card, avoiding some of the ones that have been noted as problematic on these forums (thanks for that help btw!) Still the same problem... except I noticed the card would be mounted for a split second before unmounting. If I push on the card, with the stylus for example, down to the bottom of the slot, it mounts. Let go, even with the for closed, it won't stay mounted. Thinking it was just a weird defect, I exchanged the unit at best buy... and this new unit has the same issue! I'm just wondering how wide spread this is and if somehow my local bb just got a bad batch? Have people figured out someway to fix this issue? The sd card is pretty important to me.
