Your Yamaha AV Reciver rx-v577 is on the list of supported devices. Music streaming from your android is possible according to the description. However, both devices must be registered in the same WLAN. Hope it helps. I stream my songs directly from Google Music to a Chromecast Audio connected to my 35-year-old JVC amplifier. It works amazingly well.
I have now searched all the settings in the control panel and the phone app, but I could not find any function for automatic call acceptance. I have to say, however, that I have the Fairphone Open Source OS on it, not the standard Android. It is possible that there are differences here.
I can also imagine that this could be installed later by means of an app, perhaps with root rights, which you can simply switch on and off with the Fairphone, at least with the open source variant of the OS.
The fairphone 2 comes with Accu, but without charger and without microUSB cable. These two you need to charge.
Here is the article about. Enjoy reading: https://fairphone.zendesk.com/hc...
Hello michischenkel
There is no mention of waterproofing anywhere, not even on the manufacturer's website. So I would rule it out. It will probably have dust protection like any other mobile phone. But the Fairphone has the advantage that you can open it (and clean it) without much difficulty if you need to.
There are probably no reliable values in this regard. The manufacturer's specifications (if available) are always too high and the rest depends on which apps you have installed and how many background processes are running. The battery is not the biggest with 2420mAH, so think one day with normal usage. But hardly more.
