When typing a search in the search bar, I feel like there should be commensurate bottom padding as on the top (highlighted in red). Perhaps this can be achieved by shrinking the grey space above the keyboard (highlighted in yellow). Just a note that I've cropped the top of my phone screen out.
Would look more uniform and professional — just a small visual enhancement. The whole white search bar could be widened horizontally too, to make the necessary visual real estate at the top and bottom lesser (so that the spacing doesn't look too unequal).
