I'm very sorry for the problems you've been having. Please let me know whether you have an ATIV (Windows 8 device) or a Galaxy Tab (Android device). Also, please provide the complete model code for this device.
I have a SAMSUNG GALAXY ATIV TAB, but it does not want to accept a 32gb SD memory card. If I put in another smaller SD card, it works. With the 32 gb card it hangs. Please assist, the description on the SD card reads; Transcend, 32GB(4) Micro SD HC. Thanks Anton
