Answer to "My SD card is not usable in my Galaxy E 8"

[AC Question]

Use a Samsung SD Card.
I have tried Sandisk, Lexar and Kingston - NONE of them will stay mountable or accessible.
All three of my Samsung SD cards work in the E8.

Samsung must have some signature or hidden requirement as the Sandisk cards work in Everything I have.

Bottom line - either call Samsung out for whatever they are doing or just use their SD card

Have you checked if the cards you bought were legit? I always use Sandisk cards.

Welcome to Android Central! I agree with chanchan05 -- try running SD Insight to see if the cards are what they say they are.
