Google’s $199 Nexus 7 tablet has just started receiving its very first software update, to version Android 4.1.1. Google is saying that this update brings the I/O version of the slate up to date with the rest of the Android 4.1 Jelly Bean pack and also includes some performance tweaks.

This is an OTA update, that’s available right now and it doesn’t even have a changelog. It’s a 12.6MB heavy update and the main feature is the inclusion of the Google Wallet app, that allows you to make NFC mobile payments on the go. I wonder if this update also fixes the screen ghosting issues we’ve heard about on some Nexus 7 units, but that may be a hardware issue in the end.

If you’re one of the guys/gals who already rooted the Nexus 7 tablet, the update will flash if you have stock recovery. Local search is still available, so Google didn’t prepare a workaround for Apple’s annoying patent for unified search, at least not yet. So, if you want to do mobile payments on your Nexus 7 and fix some bugs, look for the OTA update on your device.
