LTE/3G are going back and forth if not altogether dropping, constantly. For some reason, the entire display sometimes just locks up for me whenever I click a button that uses the internet. For example when logging into iCloud, it locked up for a solid minute. When triggering a dropbox sync, it locked up again. Plus the screen seems to be missing finger press registrations. While I am typing I continually keep missing keys. Anybody having similar issues? I'm not trying to be a dick about everything, just genuinely would like to know if anybody is having a similar fate.
