Switching to output connects VU-meters to internal device sound output. This can not work properly on some Snapdragon processors with some third party players cause they use specific hardware features. Author of this program is not responsible if VU-meters don't show music level on output but on microphone do show.Some software music players do not give author, album and song name. In this case static sentence "no music info" will be shown. Same will be shown if no any music playing but program just animates sound from microphone.Program DOES NOT contain any malicious code - no data acquisition, no trading, no third side communications, nothing except it really does - just music player. It only contains advertising.Program works only in landscape mode. It blocks automatic screen blackening but allows turn off screen by device power button. Just turn on music and run this program while charging your phone or tablet - and enjoy nice view instead of black screen.If you have any difficulties and/or questions then please ask them by email before post negative review.
