Last week when I was at work, my USB Charger worked fine. Now, when I plug into a USB outlet, I get "Unable to charge device... please use the supported charger" This is a brand new phone that I picked up just over a week ago. I'm guessing this has something to do with an update over the weekend. I've gone through all my settings and can't seem to find anything I can change on this. Any help would be appreciated as I work in a location where I'm not able to charge via standard wall plugs.
