80's Auto Manner Mode

Do you ever have been surprised by your phone's ring, because ringer mode was changed by pushing volume accidentally.
Don't worry about it. All you need to do is install this. No complex configuration is required.

Do you want to use speaker for games? If so, you can change sound volume as you like. When you finish playing it, I think you will push the power key (or leave your phone as it is) to power off the screen. At that time, I will change ringer mode automatically for you.

Warning: If you are using a kind of task-killer, please add this application in exception list.


By the way, I am not a native English speaker. If you notice my funny English, please teach me the natural sentence.
