There was a bug, which is mostly resolved by now with the charge switching between 3g and 4g. Sometimes it would get stuck. To solve this update the phone to the latest version available. If that doesn't fix it, then you should take the phone to verizon.

I have had the droid charge for almost 4 months now and for the most part have been happy with it. However, the past few days i have had literally no internet connection. I have tried rebooting it, taking the battery out, turning off the mobile data for awhile then turning it back on, and still no luck. There's not even a 3G or 4G LTE icon at the top. Any suggestions?
