The phone showes 2.67 gb of memory / 2.07 gb available and the SD Card as 29.62 gb available.
The Sandisk Memory Zone shows Internal memry of 2.0 gb free and Memory card of 2.0 and does not show the SD Card at all.
I have the same problem but with a Huwei P6
Using a Sandisk 64GB SDHC card
PLEASE FIX SANDISK
