Tab bar fitting at bottom

Tab bar is not fitting at the bottom in all mobile models, there is small space at the bottom. I tried to attach the image here but couldn’t able to.

The same issue can be viewed on IPhone X preview added on home screen.

Any solution for this?

Thanks in advance

Hi @Anilspr888 I believe your issue is similar to one I just answered, which you can view here: White bar at the bottom on the screen
