OK, this all sounds good enough to me to buy a new Xperia X black from Amazon Germany for 314€. Not really a steal but I don't like used units or Ebay that much.
I'm not really a big Sony fan any more but I must say the phone is really good hardware. Nice build quality, very good screen and not too slow under Android 7.0.
The only downside I found it's a little bit too big for me.
I hope they get Bluetooth fixed. I don't use it very often but I also must admit it's a very important base feature for a modern phone...
