I just upgraded to 8.1 using the Developers App and now I'm having issues with the Internet Sharing/mobile hotspot function on my 928. The connection will drop at times while I'm online, causing me to the slide the Internet Sharing tab Off to On again. Other times, when I try to turn On the Internet Sharing, the slide tab will turn grey and the loading icons at the top of the screen will appear but the screen stays in this position. The only way I can reset this screen is if I turn the phone off and on. It also appears the I can't get a connection from Internet Sharing while I talk on the phone. This is extremely annoying, as I use the Internet Sharing often. This rarely, if ever happened when I had 8.0. Anyone else run into this problem or know a solution?
