I just picked up an Xr and I'm back to iPhone after 2 years of Android. My biggest impression is just how boring and bland iOS is. As a software company Google is just way better at the software side of things and it's showing by how much Android is improving while iOS has stayed so stagnant. Google is simply doing so much more with software and as people start to own phones for longer, software then becomes much more important rather than hardware. Just look at how much Google Assistant has improved while Siri has been lagging behind. It's a microcosm of what's been happening with Android vs iOS in general. The Call Screening feature that they have on the Pixel 3 is a great example of a killer feature. Something that apple is not close to achieving. The Night Sight feature with the camera looks to be the same and vastly ahead of what Apple is capable of right now. In 2018 Android is the much more exciting OS. As a mobile OS I believe that Android surpassed iOS sometime between the 2 years I stopped using iPhone and on Android. Now the gap is just getting bigger. Now Apple has its strengths too, namely the hardware. The A12 is leaps ahead of what is out there from a mobile processing standpoint. I purchased the Xr because I wanted something really fast, stable, and with great battery life. That being said, if I had known how bland iOS is right now I probably would have reconsidered switching back to iOS.
