Screen fit must be perfect. When you do that, no issues. Especially side to side. If you have touch issues on on side, the glass is too far on that side!
Simple fix for this issue. I thank the MAN upstairs i use symbian belle and WP8.(Kidding)
Go into hotspot tether. Touch next to the on off button to get settings. ALLOW all devices. Galaxy Note updated to JB caused this i think.:D
