The Samsung TabS I use got its software upgrade to Lollipop (Android 5.0.2) on the weekend.
I'm not a giant nerd about these matters, but I have to say, the new operating system seems to have sped up the way the tablet operates in a very pleasing way.
Not sure that I've learned to love the keyboard yet, but I think I'm starting to like that too.
I also finally got around to paying all of $4 to get PicSay Pro. (I usually use the lite version to make the comic book speaking boxes in photos.) It's a very comprehensive set of photo fiddling tools, and has very a high positive rating on Google Play which is well deserved.
