Galaxy Button Light & Vibration is a simple and easy-to-use tool designed for Samsung devices. This free utility and tool application enables users to customize the capacitive buttons (Recent apps and Back keys) on their Samsung devices. With this app, users can select how long the capacitive buttons stay light and enable/disable the vibration of keys.

This application offers many selections for backlight, including always on when the screen is on, always off, default duration (1.5 seconds), or custom time on duration by yourself from 1 to 10 seconds. If you turn on Power Saving Mode, the buttons will always be off until you turn off Power Saving Mode. It's important to note that the app may not work with Custom ROMs, as only Samsung Stock ROM can control the lighting.

It works without Root permission and is easy and simple to use. However, it's worth noting that it's not supported on Galaxy J, Grand Prime, and Core Prime devices.
