It’s only been 24 hours since the device has launched and it’s already gotten its first OTA. Nothing special about that. There were no details to be had on what this “hot off the presses” upgrade is supposed to fix, but AC has it that it fixes a display issue with the web browser. Any other changes might have been under the hood, but we wouldn’t know at this time. Anyway, go ahead and update if your phone has already prompted you to do so.
