As much as I wish 8.1 hadn't shortened my battery life, along with a few other occasional quirks, I still find myself loving it. If I had the option to revert my 1520 back to 8, I don't think I would do it. Everything that I had hoped would be in 8.1 is actually there. Before I switched to a 920 and then the 1520, my previous phones were both Galaxies. It took a while to warm up to Phone 8, but once I did I couldn't go back to Android. The amazing thing is that as good as 8.1 is, it's still being tweaked and improved. I can't wait for the final updates to come out, along with Cyan (or whatever they're going to call it).
