How Do You Turn On Device Speakers For Android Using Adb Shell

Have not seen any commands regarding turning the Android device speakers on using 'adb shell', curious if there is a way? #call phone adb shell am start -a android.intent.action.CA

Solution 1:

To set Speakerphone on from adb shell use:

• in Android 4.4.4: adb shell service call audio 35 i32 1
• in Android 5.1.0: adb shell service call audio 36 i32 1
• in Android 6.0.1: adb shell service call audio 30 i32 1
• in Android 7.0+: adb shell service call audio 29 i32 1

Replace 1 with 0 to set it off.
