Recent app light not working
I have an s6 edge, it's had a full display replacement, which was working perfectly. About 5 months on, the 'recent apps' button has stopped lighting up but still responds to touch. I've googled most common answer was power saving mode, but that is for both button lights. This is only the recent apps light. I downloaded the Galaxy lights app, which didn't work either.
I suspect this is just a defective light, but was wondering if it could be something more simple that I've missed in settings or something.
Is this a good question?
