I read this on XDA. A couple of people reported that the S-pen would become very feint when it traveled across the magnet area from the case. I was so ready to get this case because I had one on my S3.
I've been getting 4G near the Agricenter on Walnut Grove, Wolf River and Germantown Road, also Fischer Steel and Germantown Road. Got some speeds as high as 25 mps. I'll do a couple more test on the way home.
Updated to RC2, and was having a wifi error. Restarted, it worked, getting errors again.
Also, can't get Wireless Tether for Root users to work. Any ideas?
