Navigation Bar

My navigation bar stops working for no apparent reason. Galaxy lite 6

Hi @SM123, does the bottom of your screen still respond (besides the navigation bar)? If you could, please send a screenshot of your screen. 

I would suggest going into settings for your navigation bar. To do this, go into Settings > Display >  Navigation bar> Tap on the style that you would like. 

Let us know if this helps!
