Unihertz Jelly Star Review 2026: Size, Apps, Battery
By Finn Albar
The Unihertz Jelly Star is a 3-inch Android phone with the full Google Play Store, so it is a small smartphone, not a dumbphone. It suits you if you need a few real apps, but it gives up any hard limit on them.
It is a mild step, stronger than a launcher but softer than a dumbphone. If you need a hard boundary, see our best dumbphones guide.
Who the Unihertz Jelly Star is for
Two profiles fit. One keeps a bank app, WhatsApp, or maps and lets the screen make the rest a chore. The other wants a second phone for trips and runs.
Skip it if you want apps to be impossible, because Google Play stays open. Skip it too if AT&T is your carrier, since the Jelly Star is not among the Unihertz phones approved there.
Price and availability
Unihertz sells the Jelly Star unlocked from its own store. Pick the US version at checkout, because the store also sells versions for other regions.
Shipping is free on smartphone-only US orders over $99, and delivery takes 5 to 10 days after 1 to 3 business days of processing. No plan comes with the phone, so you bring your own SIM. The second slot takes either a second SIM or a microSD card.
Buy from Unihertz or from a channel on its other stores page, which includes an Amazon storefront. The warranty does not cover unauthorized resellers.
What matters
Size, weight, and the 3-inch screen
The Jelly Star measures 95.1 by 49.6 by 18.7 mm and weighs 116 g. That is about 3.7 by 2.0 by 0.7 in and 4.1 oz, and Unihertz pitches it as the size of a credit card.
The screen is a 3-inch LCD at 480 by 854 pixels. That works out to a screen under 1.5 inches wide, so a feed shows little at a time and the keyboard keys are tiny. The small size is the pause, but a mild one: a determined thumb still scrolls.
Apps and the Play Store
The Jelly Star is Google-certified, with full access to Google Play. Apps are open by default, so WhatsApp, Spotify, and Google Maps come from the Play Store as usual. There is also an optional Student mode with an app whitelist, allowed hours, and site blocks.
You set the Student mode password yourself, so it is a speed bump. The Android 16 update adds an App Lock in a new System Manager, which is another speed bump of the same kind.
To make the phone calmer, add a minimalist launcher. Our best minimalist launchers for Android guide starts with free Olauncher, which turns the home screen into a plain text list.
US carriers and activation
Unihertz phones work in the US on T-Mobile, Verizon, and AT&T, based on user reports and with no guarantee. T-Mobile is the cleanest fit, because it comes with no caveat. On Verizon, the phones work but cannot activate a new SIM, so you activate the SIM in another phone first.
AT&T works only with whitelisted phones, and the whitelisted Unihertz models are the Jelly 2 and Titan 2, not the Jelly Star. MVNOs such as Mint Mobile and Visible may not work properly either. The LTE bands are 2, 4, 5, 12, 13, 17, and 66, but VoLTE support is not published, so ask your carrier before you buy.
Battery life
The battery is 2,000 mAh and non-removable, and it charges at 10 W. It is advertised for all-day use on a single charge.
That is a claim of one day, not several, so plan on charging nightly like any smartphone.
Chip, storage, and camera
Inside are a Helio G99 chip, 8 GB of RAM, and 256 GB of storage. The cameras are a 48 MP rear camera with autofocus and an 8 MP front camera with fixed focus.
NFC, Bluetooth, and extras
The Jelly Star has NFC, which Unihertz pitches for payments and data transfers. But tap to pay in Google Wallet needs NFC turned on, a screen lock, and a phone that meets Google’s security requirements.
Bluetooth is version 5.3, and there is still a 3.5 mm headphone jack. It also has FM radio, an infrared blaster, a fingerprint reader, and GPS with GLONASS, BeiDou, and Galileo.
A programmable key can run up to three actions on a click, double click, or long press. That can launch one app without touching the home screen.
Software updates
The published specs still show Android 13. Unihertz began a phased Android 16 rollout on August 31, 2026, starting with 1,000 phones. In January it had planned the update for early April.
Unihertz publishes no support end date for the Jelly Star. For the Titan 2 it promises security updates through 2030. It tells Jelly Star owners to back up first, because the update restructures the core system.
Warranty, returns, and repair
Unihertz gives smartphones a 12-month warranty that covers only the country of purchase. Its exemptions include repairs by you or a third party, and it bars returns over carrier compatibility.
It accepts non-defect returns only for unopened phones. After the warranty, Unihertz sells Jelly Star parts, including a battery, and offers repair service.
Buying outside the US
Unihertz’s own store sells US, EU, Canada, and Japan versions, plus one for the UK, Australia, New Zealand, and Asia. For countries outside those regions, such as Norway and Switzerland, the product page points buyers to AliExpress.
On orders from Unihertz’s store, customs fees may apply, and the buyer pays them. Because the warranty covers only the country of purchase, buy the version made for the country where you live.
Limitations
Out of the box the Jelly Star limits your thumb, not your apps, so a dumbphone suits you better if you need a hard boundary.
Carrier fit is narrow: T-Mobile works without a caveat, Verizon needs a SIM activated elsewhere, and AT&T is unconfirmed. It is 4G only, and Unihertz claims one day of battery.
Pros
- Google Play and Google certification, so ordinary Android apps install
- A 3-inch screen that makes scrolling and maps a chore
- NFC, dual SIM, headphone jack, and a 48 MP rear camera
- Sold unlocked with no plan attached
- Replacement parts, including a battery, sold by Unihertz
Cons
- App limits are off until you set them
- One day of battery and 4G only
- AT&T unconfirmed, and Verizon needs a SIM activated elsewhere
- Android 16 began rolling out months after Unihertz's plan, with no support end date
- No returns over carrier problems
Alternatives
Pick the Jelly Max if 3 inches is too small, since it is a 5-inch 5G phone. If you would rather keep the phone you own, a minimalist launcher is the lighter step.
Choose the Bigme HiBreak Pro if you want the Play Store on an E Ink screen that slows scrolling but blocks no app, as our Bigme HiBreak Pro review explains. Bigme gives no US carrier list, so check its bands first.
Pick a phone with no app store if you want apps to be impossible. Our Light Phone III review covers a minimalist phone with no store.
Common questions
Does the Unihertz Jelly Star run WhatsApp, Spotify, and Google Maps?
Yes, as Play Store downloads, since the phone is Google-certified with Google Play. WhatsApp needs Android 6.0 or newer and Spotify needs Android 7.0, while the Jelly Star runs Android 13 or newer. The 3-inch screen is the main limit.
How big is the Unihertz Jelly Star?
It is 95.1 by 49.6 by 18.7 mm and weighs 116 g. The screen is a 3-inch LCD, and Unihertz compares the phone to a credit card, though it is far thicker than one.
Does the Jelly Star have NFC and Bluetooth?
Yes to both: NFC for payments and data transfers, plus Bluetooth 5.3. Tap to pay in Google Wallet also needs a screen lock and a phone that meets Google’s security requirements, and the Jelly Star is Google-certified.
How long does the Jelly Star battery last?
Unihertz claims a full day on a single charge. The battery is non-removable and charges at 10 W, so plan on a nightly charge rather than several days.
Can you buy the Unihertz Jelly Star in Norway?
Not as a Norwegian version from Unihertz’s own store. Its product page sends buyers in Norway, Switzerland, and some other countries to AliExpress instead. In Norway, Telenor, Telia, and ice work with Unihertz phones, based on user reports and without a guarantee.
Does the Jelly Star get Android 16?
Yes, in phases since August 31, 2026. Open Settings, About phone, System update to look for it, and back up first.
A smartphone, only smaller
The Jelly Star is a smartphone made small, and that is both its pitch and its limit. It gives you Google Play and a 3-inch reason to open fewer apps.
Buy it if you want a few real apps and a launcher to hold the line. If you know a feed will win, skip it and start with a phone that has no app store.
