All the iDevices of Apple in their prime. I still have an old broken iPhone 4 as a reminder of what peak mobile phone design looked like. I miss being able to reach the whole screen with my thumb.
Re: thumb - I have found some gesture to pull the screen down halfway so you can reach the 'top' part without moving your hand. It's close to OK, and it's almost second nature now, but still annoying.
This. Oh, so much this. I have hated every phone after my OG iPhone SE so much because of this lunacy in design. It's ridiculous that we can't use our phones one-handed.
I know-- people don't want small phones. >sigh< I wonder if we're getting to the point that most phone users have never actually used a phone with a screen they can reach across with one hand.
