Here are my observations. But, you could get other possible suggestions from others too:
1. You are cramming too many views in one little phone screen: B4xCombos, B4XFloats, buttons, labels and on top of that a B4XTable which needs lots of space of its own. Your best bet is to create more B4XPages to distribute the views, namely one of the B4XTable.
2. Another option is to use TabStripViewPager to have multiple pages, you can scroll through.
3. Your designer script is too verbose and has too much stuff. Use anchors and fine tune with the designer script.
4. Portrait mode may display better than the chosen landscape in this case, although that is a matter of preference.
5. Connect the designer to your phone via the designer WYSIWYG menu option located in the designer, then 'connect'. feature. You will be able to see the views positioning on that phone screen which will allow you to make adjustment.
6. Do not use small text size of 6. You need binoculars to see the text. at the minmum 14, even higher.
