Refresh Roundup week of November 12th, 2012

Your smartphone and / or tablet is just begging for an update. From time to time, these mobile devices are blessed with maintenance refreshes, bug fixes, custom ROMs and anything in between, and so many of them are floating around that it's easy for a sizable chunk to get lost in the mix. To make sure they don't escape without notice, we've gathered every possible update, hack, and other miscellaneous tomfoolery we could find during the last week and crammed them into one convenient roundup. If you find something available for your device, please give us a shout at tips at engadget dawt com and let us know. Enjoy!

Official Android updates
  • Nexus 7: Earlier this week, we posted a download to update the Nexus 7 to Android 4.2. If you're not one to bother with the hassles of flashing firmware, however, you'll be happy to know that an OTA download is now ready and waiting to bring your tablet the latest that Jelly Bean has to offer. [Thanks to everyone who sent this in]
  • Samsung Galaxy Stellar: Verizon has posted its changelog for a new software update that'll hit the Galaxy Stellar smartphone. After installation, users should benefit from better voice quality, fewer device resets and improved backlight brightness after waking the phone. [Android Police]
