Is it possible to turn off the phone when using COrvus?

Yes. We have built-in screen reader which is automatically activated when “Turn off the phone” dialogue appears, so you can control it and turn off the phone, toggle airplane mode etc. Remember to turn off “Suppress system dialogues” option in Menu > Settings > Environment when you are going to use COrvus screen reader and want to navigate through e.g. “Turn off the phone” dialogue.
