Not actually. It's Android on Samsung Galaxy. Default resolution.

Look how I solved it temporarily. The Start Chat button for actually hidden below my Android navigation bar at the bottom. So, I have hidden the navigation bar itself. Now the button appears at the top and have been able to use it. But consider the display / interface issue to be solved. Nice app. Solves a long due problem solution of creating a universal app for Nostr based messaging. Thank you, @JeffG .
