3 stars: After forever getting the B27102 error, the app finally connects to the receiver. Now that it does, I'm able to see what it's functions are. It gives you fairly deep control of the receiver from your phone, but after everything is set up (which I had to do without this app), I don't use it much other than volume control. The interface is wonky, favoring flashy animations over ease of use, but it's still fairly usable. Rating 3 because it was months and months of it not connecting at all, forcing me to bypass what I'm assuming is the app's most useful stage - initial setup.
3 stars: Works some times, but unimpressed that Pioneer doesn't do anything about updating it, even after most comments are negative. I too have to reset my VSX1021 at least once a week to enable app to work. Another change from previous version is, when I initiate the app on Android, it switches the amp on which is not great. If I am using the amp with HMS for instance and activated the app, HMS stops working.
4 stars: For those experiencing B57113 error this is how i fixed it because it seems sure as hell pioneer won't. Had to power down amp completely, not just standby. Unplugged it for ten seconds pressing on button to completely drain power. Then turned it back on. All presets are kept but the connection is completely reset. Then control app worked again. Time will tell how long for.
5 stars: Works great. Had a weird issue where i couldnt connect but could ping ip address on netw...
