hi everyone! I had a problem, I updated to kit kat two months ago, after update it showed a message "SD damaged" but I restarted and then everything was fine till yesterday, first started to lagging when I restarted the phone again I saw the message of SD damaged, when I put the SD on a card adapter the format changed to raw and I cant use it again on my phone, please what can I do? kit kat is the responsible of this problem?I'm afraid to use a new SD and then get damaged once again
