Galaxy S7 and S7 edge still use two capacitive buttons for Recent app and Back respectively.
As explained in Galaxy S7 layout, Recent button is in the lefty side of Home button and Back button is in the right side of Home button.
When you touch either of the two buttons, both button will light up. This is useful when you are using Galaxy S7 or S7 edge in a dark environment.
But this can also be the problem. In some situations, you may simply not want to see the light because it can be too bright.
For experienced owners, you may know the location of the buttons well without the light.
Unfortunately, there are no options for you to disable of adjust touch button light in Galaxy S7 and S7 edge.
So, in this guide, I will show you how to use a simple app to disable touch button light in Galaxy S7 and S7 edge, and how to adjust the lighting duration.
As mentioned, Samsung removed the options for configuring touch button light from Galaxy S7 settings.
But the touch key light and its duration are still fully adjustable and controllable. The settings are simply hidden without a corresponding user interface.
What you need is a simple app named Galaxy Button Lights 2.
Step 1: Install Galaxy Button lights 2
You can search for “Galaxy Button lights 2” in Play store as shown below.
The app is free without ads and any bloatware.
Once you find the app, tap Install to install the app to Galaxy S7 as shown below.
You will get normal waning messages on app permissions.
But this app is very clean. As shown above, it does not require any special permissions.
So, you can tap Accept as shown above to proceed the installation.
Step 2: Configure Galaxy S7 touch key light
You can start the app to configure Galaxy S7 touch button light as you want.
As shown above, the app is simple to use.
There are 4 options:
- Time to remain on. This is for you to set the duration of the button light. After touch Recent or Back button, the two buttons will still be lighting for this duration. You can drag it left or right to adjust this duration from 1 to 10 seconds.
- Always on. The two touch button will light up whenever screen is on. When you turn off screen, the light will be turned off. So, the always on is a bit misleading.
- Always off. You can turn off touch button light completely.
- Default (1.5 seconds). This is actually the default setting in Galaxy S7 and S7 edge.
With these 4 options, you can tweak the touch button light for your needs.
Step 3: Save settings
After changing the settings, you should always tap “Save button backlight behavior” as shown above.
This will save the new settings and apply them to your Galaxy S7 and S7 edge.
If you forget to tap this button, the changes are simply discarded.
The touch button light is always turned off when you turned on power saving mode.
So, if you are using power saving mode, there is no way to turn on touch button light. This is the limitation set by Samsung, not the app.
If you are not using power saving mode, and the touch button light is working as expected, you may open the app and check settings. You must tap Save button backlight behavior to save your configurations.
