See a problem for a screen 6.3" high? Can barely read text in giant boxes. If the boxes were smaller most of the 66 books would fit on the screen.
I stood my Samsung S9+ in front of & beside the same screen on my Fire 10 HD Tablet, which was in landscape mode. All 66 books were displayed on the left side in boxes that would've all fit on the phone's screen, & had larger, easier to read text to boot. It's pretty dramatic how much easier they were to read, compared to the monster boxes with teeniny (really small) barely legible text in the phone app. Please fix! It didn't used to be this way.
