Change the touch key light duration on all Samsung Galaxy S6 or S6 Edge models using this app
We can’t for the life of us figure out how Samsung came to the decision to hack up TouchWiz for US versions of the device, giving carriers exclusive fundamental options others didn’t get. For instance, only the AT&T Samsung Galaxy S6 and S6 Edge models have an option to change the touch key (capacitive nav buttons) light duration. Yes, that very same option you’ve had on Galaxy devices for years now.
Well, the clever minds on XDA found a workaround, one that didn’t involve root, but involved enabling USB debugging and executing a few commands via ADB just to change it on non-AT&T S6 models. Not exactly convenient, or probably even worth the hassle. That is, unless these lights were bothering you when using your device in the dark (they can be a little bright).
Thankfully, some beautiful soul on Google Play has created an app just for this purpose. Simply put, it allows you to change the duration of those backlit back and recents buttons on the Galaxy S6 (all versions) — even turn them off completely if you’d like. Not sure why Samsung didn’t enable this “feature” on all models, but we’re glad someone out there was able to step up. Link provided below.
