I guess I am just having bad luck my with razr getting a 64gb card working.
I have formatted one card in the phone and it locked up and bricked the card, bought another card, tried formatting via easeus and one minute after card is inserted, acknowledged by the phone, the phone locks up goes to black screen with shortcut keys (menu, home, back, search) lit but unresponsive.
the card I am trying to get working is a sandisk Micro sdxc 64gb class 10.
If anyone has any suggestions, thoughts, ideas, any would be welcome.
