Nexus 7 LTE OTA Update to 4.3.1 JLS36I, first of its kind without changelog

A surprising OTA update has been silently rolling out for Nexus 7 LTE variants. The new Google Android OS has now bumped-up to Android 4.3.1 and the LTE Nexus 7 is the luckiest device to taste it first.  The new Android 4.3.1 with firmware build number JLS36I is now rolling via OTA (over-the-air). But there are no official changelog has been released or any word from Google about this said 4.3.1 as of this moment.  We also consider that this Android 4.3.1 update will also hit to other Nexus smartphones and tablets soon.

The firmware file size is just around 16MB, it’s too small to expect with more changes this update brings.  As we’ve have seen, a firmware file size like this is either for security enhancements or more on bug-fixes.  Though the Android version bumps up to a little higher from 4.3 to 4.3.1 but we are at  the stage Jelly Bean though. Its looks like Google has just clearly emphasized to the Android community that they are now in preparation for the upcoming Android 4.4 KitKat that will arrive sooner or later this year.
So if you owned the Nexus 7 LTE edition just check this update by hitting your device Settings>> About Phone>> Check for Software Update.   Any way this Android 4.3.1 build version JLS36I can still be rooted using SuperSU via TWRP recovery. If you have root and installed with custom recovery, you’ll lose it once after you accept the OTA, but you can still root it again.
