(Possibly related to Upgrade Advice?; not really I reckon.)
Is it appropriate here to ask questions about how a particular Android device will look/behave and what features it will have added/removed in case I upgrade from Android X.X to Y.Y? Not looking for a complete list compiled for me, just specific features listed in the question.
My rationale: Because one can't, without rooting the device and doing other things, go back to the Android version one had before the upgrade, I'm not exactly jumping up and down to install the newest version available from the manufacturer. I lurk on youtube for videos that feature the upgraded phone, I read articles and reviews, but when I can't find answers to a particular worry, I would really appreciate advice from a person who has already upgraded that same device.
