Hi, I have an issue here. I'm using 32GB SanDisk micro sd card Class 10 for my Lumia 820, but there's a problem while.installing the games/apps. When the installation is about to complete, it's suddenly stop and it shows "Attention required. Tap here.". Even after I try for so many times. I've tried for other apps too, but it just the same. Somebody help me. Thanks.
