5 stars: When I purchased my CSP-170, I do not believe that the android version of the supported wireless connection with my piano, but apparently it does now. After replacing my iPhone with an S21 Ultra, I looked up how to do the wired connection, but was able to connect wirelessly just as easily as with my iPad or iPhone. I love my piano and I thankful for the apparent app update.
4 stars: Works well with my Samsung S6 Edge, Android 7.0. But the screen cannot rotate, can only be in vertical mode, not horizontal mode, which makes it inconvenient since the cable port vertically below the phone, making it difficult to stand. Could Yamaha do something about the screen rotation. Make it rotate freely in all directions. Thanks.
