How to turn off/on the touch key light (return and recent) on Galaxy Note 4?

 How to turn off/on the touch key light (return and recent) on Galaxy Note 4?

You can turn on/off touch key light on Galaxy Note 4

Similar to all previous Galaxy Note and Galaxy S phones, Galaxy Note 4 has 2 capacitive touch keys in each side of the home button.

The touch key in the right side of the home button is a return key or back key. The left one is called recent apps key showing the recently opened apps.

By default, when you touch either of the two touch keys, both of them will be illuminated. This can be embarrassing when you try to reply an urgent message in a  cinema.

In daytime, you seldom need the light to guide you.

Of course, lighting the touch keys may consume considerable battery  and therefore it may drain your battery noticeably if the duration of  illumination is too long.

In Galaxy Note 4, you now can turn on and turn off the touch key light to save battery.

This guide will show you how to turn on/off the touch key light, how to set the duration of the lighting, and how to access the new touch key light settings in Galaxy Note 4

How to turn on/off touch key light on Galaxy Note 4?

In Galaxy Note 4, the switch for turning on/off the touch key light and the settings for the duration is under Settings—Display and Wallpaper.

You can go to Settings, tap Display and wallpaper.

Tap Touch key light duration.  Then you have 4 options (same as other Galaxy devices):

1. 1.5 seconds.  This means touch key light is on and the light goes off after 1.5 seconds.  This is the default setting.
2. 6 seconds.
3. Always off. This option essentially turn off touch key light. The touch key will never be illuminated. This setting will not be overwritten by any other settings.
4. Always on.  This option turns on the touch key light permanently.  It is NOT recommended for most owners.

I  didn’t turn off the touch key light, but neither of the keys are illuminated on Galaxy Note 4. Why?

Among the 4 options mentioned above, in the old Galaxy devices, none of them can be overwritten by other settings.

In Galaxy Note 4, however,  options 1,2 and 4 can be overwritten by power saving mode.

So, this explains why your touch key light is off even your setting is on.

You can tune this settings at Settings–Power saving.

In Power saving page, tap Power saving mode.

Tap Restrict performance.

Now you can un-check Turn off touch key light (it is checked by default). This will turn on touch key light when power saving mode is enabled.

Of course, you can turn off restrict performance totally.
