From Google's response:

> If you are unsure what Android version you are on, confirm you are running Android 10 or above

My Xperia X is still on 8.0.0, it only got a few months of updates before they just silently stopped sending them, displaying that my "device is up to date!". This is a widespread problem in the Android market, in comparison, my iPad Air 2 is still getting updates 8 years after release. Google keep saying that they want to work on this, but realistically, is it ever going to happen?
