How To Fix Touch Key Light Not Working On Galaxy A9, A8, A7, A6, A5, A4, A3

The touch key light looks like a simple feature of a Samsung Galaxy A9, A8, A7, A6, A5, A4, A3 and, as a matter of fact, of any Android device out there. More often than not, we never take the time to think about it and try to understand how it works and why it works that way. At least until it stops working, or we think it did, but we’re not sure.

Of course, we’re not sure if it’s a problem or just a matter of settings because we don’t really know anything about it. All that will change today when we tell you that the touch key light of Samsung Galaxy A9, A8, A7, A6, A5, A4, A3 is actually a feature that can be enabled and disabled from your phone’s settings.

Before you conclude that it stopped working, ask yourself – what if it was accidentally disabled?

Here’s another interesting news – the light setting can also be automatically disabled, in one particular instance. When you’re running out of battery and the A9, A8, A7, A6, A5, A4, A3 will switch to the energy saving mode, this is one of the first things that the device will “sacrifice”.

You can check the key lights settings if you go to: Settings >> Quick Settings >> Power Saving >> Power Saving Mode >> Restrict Performance >> uncheck the “Turn off touch key light” option.

Remember, the touch keys normally light up and show you that the device is working. When they no longer light up but your Samsung Galaxy A9, A8, A7, A6, A5, A4, A3 still responds when you use those keys, it’s a clear sign that you’re rather looking at a settings issue.
