Anyone else having issues when switching between 3G and 4G? I am finding that when I toggle between them the phone won't pick the 3G signal back up. EDITED: I think I have found the problem. For some reason LTE Switch app seems to cause a problem. Others are having this issue on their Bionics, and, if you read the reviews, this is a reported problem on other devices as well. My recommendation: DO NOT DOWNLOAD LTE SWITCH.
