NGC 4388

NGC 4388 provides following utility without ROOT permission.

1. Fixing the volume key with the media instead of ringer.

2. Provide detailed media volume as double steps of common case.
(Entirely 30 steps, more 10 steps when your volume guage under 1-bar)
*But this function is beta-version and it uses master-volume if your phone is not Galaxy nougat(7.0) version.
So you need to have caution when using this function.
(If master volume is 10%, then Alarm or Ring tone also 10% of common case.)

3. Silent function when shooting camera: It is used for self-portrait, baby picture, and animal picture.
(If your phone's default camera doesn't support silent shot, then this func. is useful to you.)
* This function is prohibited to use for illegal purpose.

4. Search for cell phone with specific code: This function is to turn off silent mode and maximize the ringer volume to make it easier to find when it is hard to find after losing a phone in the house.

5. Screen On Extension: This function is to prevent screen off during Internet or community reading.
When set, the screen turn-on time is set to maximum (the screen turn-off time is restored when the function is turned off or rebooted).

6. Set the screen to darker: Set the screen brightness to a darker setting to prevent glare when viewing the phone late at night.

7. Flashlight - Provides an notification icon that allows you to turn the flashlight on and off.
