Unclear yet what's changed in new build JLS36I
We've seen some minor updates to Android 4.3 in the couple of months since it first arrived, but today it seems Google's OS may have finally graduated to version 4.3.1. An over-the-air update now seems to be pushing out with the incremented OS version, with the LTE Nexus 7 being the first to get it.
The update weighs 16.6MB and brings the Nexus 7 LTE up to Android 4.3.1, build JLS36I — and although it's unclear specifically what's changed in the new build, previous point releases have mainly been minor, bug-fixing updates. We've popped in an AT&T SIM for good measure and are sad to report that tethering still is a no-go.
We'll keep our eyes peeled for the arrival of 4.3.1 on other Nexus phones and tablets. In the meantime be sure to hit the comments and let us know if you see the new version of Android on your device.
