What is an echo button?
The echo button is a tiny speaker attached to the side of your phone’s front or back that plays a notification.
The echo buttons are used to trigger actions on your phone that don’t require any actions from you.
In the past, they have also been used to enable remote notifications, such as an incoming call or notification for a friend.
If you don’t use the echo button, you may not know what it is.
What does it do?
By default, the echo is set to OFF.
If the echo has been turned on, you will hear an audio notification, followed by a click to turn it off.
If it has been set to ON, the notification will play when you turn the echo on.
How to uninstall the echo from your device?
Delete the echo device file and delete any files related to the echo.
In my case, I deleted the file called echo.old, which was in the /system/app/com.google.android.voice.emulator/ directory.
Then, delete the android_emulator_sdk directory.
In order to remove this file, open the file, then double-click the old file.
If everything works, the new file should now be visible in the phone’s directory.
If not, open a file explorer, locate the file you want to remove, and double-check that the file is there.
You can also delete the file in a file manager like Notepad.
Remove the old echo device files from your Android device.
Open the file that you want the old device files removed from, then delete the following two lines: android_app_emulators_sdks/echo_old.old android_apps_sdck/echo.old.android_apps.old Android device files are the files that are installed on your Android devices and are required for certain features of the phone.
If you want your device to be silent, then you need to delete all the echo files and their associated files.
This step may be necessary for some devices that have a low battery life, or for certain devices that don\’t support Bluetooth, or otherwise aren\’t supported by your phone.
If your device supports Bluetooth, delete any Bluetooth audio files that were installed on it, and delete the Bluetooth device file.
In my example, I have removed all the Bluetooth files that came with the Echo, including those that are required by Android apps that need Bluetooth.
Reinstall the Echo.
Open a file browser and go to /system, then search for the android app that is installed on the Echo device.
In this case, the android file was called echo, so delete it.
This will remove the device files and the Bluetooth devices.
Repeat the steps for the old Echo device files.
If all goes well, you should see the old devices listed as well as the new devices.
You now have your Echo device and should be able to use it to control a phone without the need for an external speaker.
