Most smartphones in the world right now have lots of Google inside them due to the Android platform being the most widespread mobile OS. And Google also offers stuff for other platforms. And here in Europe, buying your own phone is actually a viable alternative.
As for Germany, it is pretty much a mixed bag. I have heard foreigners being amazed at how well English is spoken and understood here, while from my experience, there are still many who have trouble with what is essentially the international standard. It is just that other countries in Europe can be worse in that regard I guess.
And despite Germany being home and haven of nude recreation, we are not some nudist utopia. Getting naked in public in areas that are not established naturist spots or fairly secluded can still get you into trouble.
