My first Android phone was a Samsung Galaxy S2. It weighted two grams less than that Hiby R1. Of course it was much larger, but tiny by today's standards.
Now that I think about it, going no-buttons might have been a driver towards larger screens. Having at least a few buttons seemed to make it much less necessary.
I loved the buttons on the Galaxy Spica https://www.gsmarena.com/samsung_i5700_galaxy_spica-pictures...
