Jelly Star – The Smallest Android 13 Smartphone

Original Article ↗ Hacker News Discussion ↗

A palm‑sized Android 13 phone with a 3.5 mm headphone jack is attracting people who want modern apps and connectivity without the distraction of a large screen. Commenters praise the Jelly Star’s ultra‑compact form factor for calls, messaging and basic apps, but report trade‑offs in build quality, battery life, network compatibility and especially long‑term software and security updates. The conversation broadens into a lament that mainstream Android vendors have largely abandoned truly small phones, leaving niche devices like this — often with weak update policies — as the only option for fans of compact hardware.

Use cases and appeal of the Jelly Star

  • Several people use it as a primary phone or a dedicated minimal device.
  • Common core uses: messaging (especially WhatsApp), music, navigation, tickets, and NFC payments.
  • Strong appeal for reducing screen time: small size and awkward typing discourage doomscrolling while keeping essentials available.
  • Also used as: backup/emergency phone, travel “burner” for high‑risk trips, and a compact device for kids or medical-device control.

Form factor, ergonomics, and features

  • Very small footprint is praised; thickness is divisive. Some find it comfortable and rugged, others say it looks “absurdly” thick.
  • Typing is “painful but serviceable”; swipe keyboards and voice input help.
  • Headphone jack and microSD are major selling points given their disappearance on mainstream phones.
  • Some wish for better screen-to-body ratio and a slightly larger (4–5") but still compact phone; many cite past favorites like Moto X, iPhone SE/mini, Sony Xperia Mini.

Build quality, durability, and networks

  • Reports of cheap-feeling build and hardware failures (buttons, headphone jack) after many drops; others say older Unihertz devices survived heavy abuse.
  • Battery life on earlier Jelly models was sometimes too poor for a full day; one Tank Mini model is praised for week-long battery life.
  • Not all carriers (e.g., Verizon, some MVNOs) accept IMEIs, which can be a hard blocker.

Software, updates, and custom ROMs

  • Repeated complaints that Unihertz rarely delivers promised Android version upgrades or regular security patches.
  • Some see this as making the phone “e‑waste,” especially for banking / corporate apps that enforce security baselines.
  • Others argue alternative ROMs (e.g., LineageOS) can prolong life, but experiences vary: some report great stability, others constant bugs, dropped support, and SafetyNet/Play Integrity failures.
  • Lack of GPL-compliant kernel source and incomplete blob support makes third‑party ROMs harder and less trustworthy.

Market context and alternatives

  • Thread broadens into lament about the near-extinction of small Android phones; iPhone mini/SE and Asus Zenfone 9 are cited as rare efforts.
  • Upcoming Jelly Max (5" screen, very thick) generates interest but also concern about updates and size.
  • Many would accept lower specs or price for a truly small, well‑supported phone.
