1. After a while, I think dust would inevitably get in the hinges and wouldn't fold flat. I've seen demos in stores of newer gen Samsung foldable phones and it looks like those wouldn't fold flat
2. The inner screen protector eventually lifted off the screen, causing catastrophic damage, and requiring repair (under warranty thankfully)
3. The aspect ratios were weird. I ended up using native app sizes, making the extra space kind of a waste
One thing I did like about the Samsung foldables was that when they were folded and using the front screen, I finally had a phone that fit my smaller hands! It was nice being able to use my thumb to reach the other side of the screen. Will be interesting to see how this works out because it looks decidedly wider.
