Answer and reject buttons not working with Google TalkBack screen reader
When using linphone Android together with the TalkBack screen reader, the buttons to answer or reject a call are not usable. The typical gesture for TalkBack users to execute a button is to double-tap it. TalkBack recognizes the buttons correctly, but when double-taping it, simply nothing happens.
