How To Fix Galaxy S8 And Galaxy S8+ Plus Key Doesn’t Light Up

You’re looking at your Samsung Galaxy S8 or Samsung Galaxy S8+ Plus, after you’ve just unlocked the screen, and it seems to you that the touch keys don’t light up? It’s hard to miss this observation, after all, you have only two touch keys, sitting right at the left and right of the Home button. They are also the indicator that the device is working properly and they always light up when the screen is turned on.

If you recognize the entire above, hold your thought – it doesn’t mean that the touch keys are broken, just because you no longer see the light turning on. More likely, there’s too much light around you, making their light barely visible, perhaps even not visible at all. And there is also the alternative that the light has been turned off from the settings… That’s right, there’s a special menu that controls whether these touch keys should light up or not. And there are instances when the device could disable the feature simply to save the battery power and reduce its usage.

First, try to go to a darker room and test the touch keys. If nothing changes, you can suspect that the Samsung Galaxy S8 or Samsung Galaxy S8+ Plus has entered the energy saving mode or anything else blocked the touch key lights. Here is how you can check that option and fix the issue:

  1. Go to Settings;
  2. Navigate to the Quick Settings section;
  3. Tap on the Power Saving option;
  4. Then, select the Power Saving mode;
  5. Also, tap on Restrict Performance;
  6. Look for the “Turn Off touch key light” feature;
  7. Tap on it to uncheck its box.


Leave the menus and confirm that your Samsung Galaxy S8 or Samsung Galaxy S8+ Plus touch keys’ light is working flawlessly.
