Samsung Galaxy S4: How to Adjust Touch Key Light Duration

Multi Window is an advanced feature that you can find in the Samsung Galaxy SIV. This feature will allow you to open two apps at once. You can enable this feature through the Settings menu or through the notification panel. After this feature is activated, you'll see a half circle icon displayed in the left/right side of the screen that you can use to display multi window tray. If you don't see that icon, you can bring it up by long pressing the Back key.

One day, an insider sent her email and said to me that she always had a difficulty to remember where the Back key is located when she want to bring up the multi window tray icon. Well, by default, the Menu key and the Back key only display their icon when you're touching one of them and they only light up for a few seconds, so it sometimes makes the user (especially with the new users) hard to remember which the Menu key and the Back key are. Luckily, this phone has an option which will allow the user to increase or decrease the touch key light duration.

How to adjust touch key light duration?
Below are the steps to do so:

1. Go to Settings.
2. Tap My device tab.
3. Tap Display.
4. Scroll down to find Touch key light duration, then tap it.
5. Here you'll see 4 options available, they are:
• 1.5 seconds: Select this option to make the Menu key and the Back key remain light up for 1.5 seconds after you touched one of them.
• 6 seconds: Select this option to make the Menu key and the Back key remain light up for 6 seconds after you touched one of them.
• Always off: Select this option to make the Menu key and the Back key don't light up even when you touch them.
• Always on: Select this option to make the Menu key and the Back key always light up even when you don't use them.
6. Select the desired touch key light duration you wish to use.

By knowing what the function of this option is, now you can set it according to your need. So, if you have difficulty to remember where the Back key and the Menu key are located, you can increase the touch key light duration or even set them to always light up during the screen is on, and vice versa.
