"Earphones" are indispensable for listening to music on smartphones and using video streaming services.If it is a modern terminal, many users will use Bluetooth earphones.It is a convenient item that does not reach out to your smartphone because you can instruct AI function calls such as pause, song skipping, Google Assistant, etc. with your hands/ears.
Many Bluetooth earphones also support volume adjustments.In the initial value of the Android OS, when the Bluetooth earphone is connected, the volume on the Android terminal side is fixed, and the adjustment is set on the Bluetooth device side.When changing the volume, it will be operated on the Bluetooth earphone side instead of an Android device (the same is true for Bluetooth speakers).
However, in the case of Bluetooth earphones with restricted size, the volume adjustment function is mostly assigned to buttons and touch panels.As a result, there are many products that are 15 steps of volume adjustment, and there are problems such as the width of the volume that goes up and down by pushing a button is too large, and the sound is loud at the minimum.
In such a case, turn on the "Disabling absolute volume" switches in the developer options in the "Settings" app.This switch can cancel the volume fixation on the Android terminal side when connecting to the Bluetooth earphone, and adjust the volume on both Bluetooth earphones and Android devices.Adjusting both can solve the volume and minimum volume problem.
In addition, since the developer option is set hidden at the time of factory shipment, tap the build number on the "Settings" → "System" → "Terminal Information" screen 7 times.Then, it will be added to the "Settings" → "System" detailed setting column.
