I used the Jelly for a while, mostly it worked very well, only a couple apps had layout issues. I think it was just slightly too small at 3", and 3.5 - 4" would resolve basically every app layout issue I had with it. My biggest problem with it was actually that the camera was awful.
That would be roughly 4.6 inches, don’t forget that modern apps don’t work well on very small displays like the UniHertz Jelly.
