Audio Output Switcher & Tester

Audio Output Switcher & Tester lets you choose where your phone plays sound: the loudspeaker, wired headphones or a paired Bluetooth device.

It also helps when the phone acts as if headphones are still plugged in. Turn on the switch, pick speaker mode, and test each output with a short listening test.

What you can do

• Route audio to the phone speaker, to headphones on the 3.5mm or USB jack, or to a Bluetooth device

• Get help when the headphone icon stays on with nothing plugged in

• See the headset status at a glance: speaker mode, earphone connected or Bluetooth active

• Test the loudspeaker, the earpiece and your headphones: listen to spoken numbers and type them in

• Use the app in 10 languages, including Arabic, German, French, Spanish and Japanese

How it works

Open Change Mode, turn on the master switch and choose Speaker, Bluetooth or Headphone. Then open Sound Test to check that the chosen output plays clearly.

Good to know

The app asks for Bluetooth access to route sound to paired devices. It shows ads, and an optional Pro purchase is available.

Pick the output, test it, and hear your phone the way you want.
