It's not a "flagship" but it is fully featured - nothing spared - and half the size of my palm. The screen is just small enough to be too annoying to do anything really distracting on. I have gotten NOTHING but compliments on it since I started using it a month ago (on a reco I picked up here).
I then upgraded to an iPhone SE, but miss Android apps like Termux, PDANet, and MiXplorer. iOS lacks compelling alternatives: A-Shell, iOS-Socks-Proxy (running in A-Shell), and Apple Files + Readdle's Documents are decent, but don't measure up to the aforementioned Android apps.
All that makes the Jelly 2 an attractive choice. It ticks the essential smartphone boxes but discourages excessive use (doom scrolling, Instagram, TikTok, Hacker News, etc).
