Perhaps try exchanging covers? Mine works perfectly and is the best accessory I could have bought for it (even paid less than MSRP).
Samsung Galaxy Note 10.1 3G (GT-N8000) on AT&T
Samsung Galaxy Note 10.1 2014 LTE (SM-P607T) on AT&T (and T-Mo/VZW)
HTC First on Net10/AT&T
(Save your "Thanks"; couldn't care less)
