And did you format the SD card in your phone before you started. Are all apps give errors or only some. (You know, I presume, that some apps can not be moved to the SD card.)
I must admit its a ebay debranded Samsung high capacity.. or who knows.That's odd .
What is the class of the SD card ?
Is it Fat32 ?
What the file's size"movie" you are trying to play ?
If its more than 2GB its gonna be hard to handle it using fat32
. Backup your SD card to your PC move your apps to phone then format it to "exFat" its better for 64GB cards I have it with no problems up to 6GB films ��
Hope this helps
