No, unfortunately Android 5.1 Lollipop didn’t fully mend the pesky malfunctions introduced by 5.0, so it’s only natural Google tried again with a 5.1.1 version. This sounds like it’ll bring even less new features to the table than 5.1, possibly none whatsoever. Just a solution to memory bleeds. Probably. Hopefully.
It’d of course be nice if the search giant concluded the 5.1 rollout for its entire Nexus lineup before doling out .1.1 source code. Unless maybe some of you purists are due straight for OTA bumps to the next OS iteration.
For the record, the existence of a smoother, more stable firmware is corroborated by Android SDK Manager evidence, so all Big G has left to do is iron out whatever final kinks haven’t been handled as of now, and subsequently give 5.1.1 the green-light. That should take a few days, a week tops… if no new snags enter the picture.
