I have 3 pieces of Lexar micro SDXC 64GB UHS-I x633 which I bought from a local distributor at the same time.
I have 2 pieces of Galaxy S2 (I9100), a Galaxy Camera (GC-100), a Galaxy S4 (I9505) and a Galaxy Note 3 (N9005).
I have not tested the cards on Galxy S2.
I have placed the 3 cards into GCam, S4 and Note 3.
All 3 of them gave me the same problem which is, some of the photos taken by those 3 devices will get greyed by like 10 to 20 percent.
I don't get this problem when I am using my Samsung and 2 Sandisk card which is 8GB and 16GB respectively.
Samsung Card for my GCam and Sandisk card for my S4 and Note 3.
I am not sure if it's the card problem or is Lexar cards having compatibility issues with Samsung devices.
Is there a cure for this?
