Not an author, but I've been using Jelly Star with a stock Android for 2 years.

Actually, typing this comment right now with this phone.

1. Keyboard: MessagEase or ThumbKey + Jelly Star is a perfect match.

2. Bitwarden passkeys + Firefox doesn't work. As I've researched, same with LineageOS. Didn't check Chrome, though.

3. All apps work without issues. Banking, Google Wallet, taxi, etc. It's a regular Android.

4. Battery isn't great, but charges fast and enough to carry on through the most of the day.

5. It's perfect for running or other outdoor activities.

6. 4G only, I sometimes also use it as an external modem for the laptop, and definitely would appreciate 5G.

7. Android 13 and no updates:/

All in all, I'm happy, but if I could foresee it advance, then I'd go with Jelly Max instead, because freshier Android version, Bitwarden + Firefox passkeys and 5G support.

Unfortunately, Jelly Max a bit bigger than Jelly Star, but still much smaller than other regular smartphones.
