The Android smartphone always has volume keys. The above key is used to increase the volume, whereas the key below is used to reduce the volume down. These keys are essentially micro-switches made of metal. When used a lot, these metal keys will wear down and no longer work properly.
If the volume keys on your Android phone are broken, you can still adjust the volume up or down using the virtual sound key set in the Virtual Volume Key application . The application displays volume keys right on the phone screen, so you can increase or decrease the volume by touching the virtual buttons on the screen.
To use the Virtual Volume Key application, you need to install and turn it on. Immediately these volume keys will appear on the screen. You can move these keys anywhere on the screen. When you release your hand, these keys will fade and be attached to one side of the screen. The opacity of the volume keys depends on the " diaphaneity " value of the application. In addition, you can adjust the time for audio keys to be attached to the edge of the screen with ' waite time ' value.
These virtual volume keys work exactly like physical volume keys. It is a great choice when the metal volume keys are damaged or worn due to heavy use and for a long time. You can also use the application to protect the audio keys on your phone.
