How did you get it?
Half or more of these records in my humble opinion is unnecessary - but maybe I'm wrong.
And just out of curiosity - write to us next to each line what is the command and what it will - I think, and I and others Colleagues eager to learn something new.
I think that once you have it on your phone - you know what that does. It's interesting.
(and by the way he apk. installed?)

Oh - one more thing - make a screenshot with sound slider settings as shown, speech, etc (Volume setting section)
