SDK的には活きてるはずなのにAndroid10の多くのデバイスでスピーカーフォン動かなくなっちゃったんだって
10以降で機能削るつもりだったけど動いてる人もいるから警告出して注意喚起に留めるらしい

Sorry for the delay in replying. This is a difficult issue as it seems like since Android 10 the speaker phone functionality no longer functions on many devices. There is no known reason for this as the functionality is still in the Android SDK and has no warnings about being deprecated or blocked in any way.

I did plan to remove this feature for Android 10+ but some users have informed me that it does work for them, therefore if I remove functionality that works fine for these users (and presumably many more silent users) I will then be breaking something that works fine for these devices. I think I should just add a very explicit warning that the functionality does not work on many Android 10 devices so at least it's clear to the user that this may not function.
