I have nothing but good things to say about this device, which I have lovingly dubbed 'the bean'. The hardware feels surprisingly high quality for the device's, low price, and the colour is absolutely stunning in all different kinds of lighting. Bean runs perfectly, as expected, and to my surprise was running Android 11 out of the box, rather than the advertised Android 10. The haptic feedback when using the capacitive navigation buttons at the bottom bezel of the display is satisfying without being too much, and despite the size of its battery, I get surprisingly good life out of it. I use the combination of slide typing and voice to type so the small keyboard area doesn't act as an issue in my case, and this has actually become my preferred device for music as my wireless earbuds sound better on the bean than they do on any of my other devices. The programmable side key with its nice accent color is also a very functional and welcome addition, and the device is perfect for my job where it's smaller stature in my pocket makes it less likely to get wet when I'm making beverages and cleaning dishes. Very very glad I bought the bean, and I would recommend buying the bean if you think you would have a use for a smaller device, or even if you just want it because it's cute.

Fantastic phone, small but very usable. Love it!

I tend to only use a phone for talk and text, and prefer models that are smaller than my iPod Touch, preferably a good bit smaller. Preferably the size of my old LG enV2, if I'm being honest.

I used the Unihertz Atom for a month but found the keyboard too small even for my minimal uses. It was excellent as a way to deter excessive, or any, screen use, but even typing a word or two was frustrating. I switched to Jelly 2 about a month ago and the difference is amazing. I am absolutely in love with this little phone!

Even with my bad eyes and clumsy fingers, texting is very doable with no more errors than I make on my iPod Touch keyboard, especially with the Swiftkey keyboard app that supports swype typing. I wouldn't want to type long emails on it, but I have no problem texting or typing short emails. Discord, Facebook, Flickr and Chrome are all very functional and easy to use even on such a small screen. Despite the fact that I try to limit my phone use to talk and text, I find myself using it for other functions that I'd normally use over WIFI with my iPod Touch.

I appreciate that Jelly 2 has more RAM and storage than Atom, and that it supports a micro SD card in the second SIM slot. I'm using it with a Verizon SIM card that was activated in a Verizon phone and switched to the Jelly 2. So far, no problems with Verizon as my service provider. Although I liked the rubberized grip of Atom, I prefer the removable case that Jelly 2 has, and hope it will be available as a separate purchase and in different colors at some point.

I prefer the older Android app drawer style UI, but the Clean Launcher app decently provides that functionality. I'd also like it to have a larger battery, although I know that's a trade off with keeping the device size small. I was getting 3 days between charges with the Atom but can't seem to go more than 2 with Jelly 2, probably because I'm tempted to use it for more than just talk and text. Overnight battery drain is about 1% per hour on standby in battery saver mode. I don't like that you can't see the battery charge level in battery saver mode. The icon at the top doesn't display a visual level or percentage.

If you value a small footprint over screen or battery size, Jelly 2 can absolutely function as a main smart phone replacement. If you enjoy watching videos or playing games on your phone or need to do a lot of typing, it may not be the best choice. If you want a tiny, rugged phone to use as a temporary alternate to a larger or more fragile device, or something that will really discourage screen use, go with the Atom.

Photos below include a comparison with the Unihertz Atom, iPod Touch and LG enV2.

Unihertz Atom, a pocket gem!

The Unihertz Atom is a pocket marvel, as it manages to have the function of a capable smartphone in a tiny form factor. You get a great, pocketable device that has good performance. 4gb of ram and a helio p23 processor make this device very snappy. Because the screen is so small (about 2.4") it doesn't need a lot of processing power to render the pixels on screen.

Everything works as it should, the phone is running android oreo, so is fairly up to date. It has 64gb storage (no micro SD card support sadly, but the 64gb is nice in this price range). The phone is running virtually stock android, with a few additional apps added by Unihertz, which are ideal for outdoor working or activities (It is a rugged phone after all).

The phone has a 2000mah battery. This battery while not amazing, should get you through a day and possibly two or more days if you are a frugal user. The most I managed was 4 days, but that requires you to switch off a lot of background apps and put the phone in battery saver mode and airplane mode overnight. Over two days with moderate to heavy usage I was able to get about 6 hours screen on time. The battery was down to about 8% at that point. The problem is the phone loses a fair bit of charge in standby. You can mitigate this by turning WiFi and/or mobile data off when you're not using it and turning on the battery saver. Overall I think the battery life is decent especially considering the battery capacity. It also charges quite quickly. At just over an hour for me from 15%-100% using the supplied charger. (I didn't get a three pin adapter with the phone, but bought a 3 pin travel adapter that works fine.)

The camera is probably the phone's weakest point, although I use it all the time. You can get quite decent pictures from the camera in good light. It's also quite fast at taking the picture. HDR mode really helps with landscape shots, making the colours pop. Or you can use your favourite image editing app to adjust the colours later. I use Snapseed for this. The camera sometimes has a focusing issue where the picture or video looks blurry. When this happens it best to re-adjust the angle until the image in the camera viewer looks clearer. Low light images are not great so avoid taking pictures in these conditions if you can. You also need to try and keep your hands steady as it will blur the picture otherwise.

Video can also can good as long as the lighting is sufficient and you check for any blurry focusing issues. The biggest problem with capturing video is the lack of image stabilization, so you will need steady hands to avoid a jerky video. If the video isn't too shaky, you can improve it by using the stabilise feature in the Google Photos app.

Despite the camera's faults, because of the phone's small size, it is convenient to take out of your pocket and take a quick photo or video at a moment's notice. I don't think the camera is terrible, because you can get some really nice pictures. It's just getting used to the quirks. (See some of my pictures attached)

The rear mounted speaker on this phone is actually quite loud. I was surprised how loud it goes! It can sound a bit tinny at high volumes, but you should have no problem hearing it in noisy environments. The phone also has a headphone jack which is very useful if you only have wired headphones or require an aux connection to a speaker or car sound system.

Phone calls sounded clear enough to me and WiFi is generally reliable. The phone is 4g capable and works well for me using an ee SIM. I did notice the phone heats up quite a bit when using mobile data for a while, so you might want to be careful leaving mobile data enabled for long periods.

Gaming is certainly possible on this phone, but the tiny screen makes it very hard to play games effectively. I stick to the ones requiring few onscreen controls. Crashy Cats is one I play a lot and while it is a bit harder to see what's going on, you do get used to it.

The keyboard is also tiny, so expect to make a few typos when using it. You do get used to it with time, or you can use swipe gesture keyboard controls or even voice controls using the Google assistant. It might also help you to put the phone in landscape mode while typing, as the keys will be spaced wider apart.

Fingerprint and face unlock are the two main security methods. I have set up both. The fingerprint scanner is great when it works, but often doesn't, I think because it just too small for your finger. I use my thumbs to unlock and the successe rate is about 6/10. Face unlock is quite reliable, but the default use requires you to first press the power button and then look at the screen to unlock. You can't unlock the phone when the display is off using this method, whereas you can with the fingerprint sensor.

I like the fact that the phone has notification LEDs. You can change these in the settings and have a red, blue or green light for different notifications. I found that reall...

Do not mistake this for a kids' phone or a toy or a joke. This is a happy little phone.

I love the feel of this in my hand. I love the color. I love the memory stats. The battery hangs in there for phone setup and turning off and on and changing all the settings. Lowest it's been has been 49% after a day of playing with it and setting it up. It doesn't run hot. The cover they sent with it is just as cute as this phone. The screen resolution is so good you will do a double take and say Wow. You are thanking whomever created this for doing so. The keyboard is small but perfectly doable. You just type and with few errors. It comes with different sounds than the usual. What a nice surprise that was. I have been using i.Atype keyboard for years so that was the first install. It is a keyboard that allows you to adjust the height of the keyboard. So that works really well to make the keys a little larger without having to turn the phone a landscape view.

This phone is a real phone. You just use it like your regular phone only you are not lugging around a big bulky, or too tall and skinny phone. This fits the hand like a glove. One-handed stuffs works well. Icons look gorgeous on the screen.

It's a cool little happy phone and I'm very happy with it. I'm older so the SOS button is good. There is a red button on the side for setting that up, but right now the red button turns on this really bright LED light. It updated to from 10 to 11 without hiccup. I am using a 256 gb SD card.

Only things I wish were different. I have to try to figure out how not to share my sd card with the phone, and I wish that the screen saver that is on the phone was a better quality.

I'm still exploring but just wanted to come on and say don't worry with it. It works. Oh, it has reminder feature. You tell it to remind you to get up and take a walk, etc. I use Tello as my phone service. Calls are clear and crisp. No dropped calls so if you using Tello not to worry. Great service provider for a great phone. They use T-Mobile towers.

If you turn on the sound enhancement feature, the volume of this phone, and the clarity of the sound will leave you sockless. Makes a great little music player. And the equalizer works. I'm not a geek so can't get into all the endless little mechanical details. All I know is I am getting rid of great phone, and I bought this phone and have no regrets.

Tiny, powerful, minimalist phone w/hidden features!

This tiny phone packs a big punch! I purchased the Jelly 2 to try and reduce screen time and practice a more minimalist approach to smartphones. It has served that purpose very well so far! The phone is much quicker than my old LGV20, and the battery life is superb for such a small device. The extra thickness is noticeable but worth it for me personally for the extra battery life. This phone does everything a normal-sized smartphone would do, including running all my apps (music streaming, navigation, email, messages, banking, stock trading, calender, radar, etc.) in a much smaller package that is just more fun to use. I also love that in includes a headphone jack, IR blaster/remote, and even a fingerprint sensor. Can't ask for much more than that in a tiny 4G smartphone.

The Good:

Speed; snappy processing/navigation speeds, probably due to such a small screen and fewer pixels. But I'll take it! Absolutely blasts past my old LGV20, which was a flagship in 2016 and has a Snapdragon 820 chipset.

Camera; I'm going to include this as a pro for this device since I wasn't expecting much from a phone this size/price point. I was pleasantly surprised however, and most photos have turned out pretty decent. Good lighting helps. Whether close up or taking nature shots, the camera isn't "great", but it is certainly acceptable. (See pics for reference)

Fingerprint Reader; after registering the same finger twice, I get nearly 100% success using the fingerprint reader. That's a good thing, because it's my preferred method of unlocking the phone. I also like that it was kept on the back of the phone, rather than an in-screen reader.

Calling; I was worried about the mic being so far from my mouth while talking on the Jelly 2, but so far I haven't had to repeat myself. I am able to hear the other person, and they are able to hear me just fine. The earpiece speaker may be a bit quiet if you are in a noisy environment. I did notice "HD" on the screen during my last conversation, so apparently the phone is capable of HD voice calling as well. Has not dropped any calls yet.

Battery life; I put this phone to the test my first few days, purposely charging the phone to 100% and using it until it literally died in my hand. I can stream music, search the web, use navigation, send texts, and even make short phone calls for hours before the battery fully dies. I do wish the battery was removable so that it could be easily replaced once it begins to deteriorate. Hopefully Unihertz will offer a battery replacement at a decent price when this does inevitably happen. I would estimate I'm getting about 4-5 hours of screen-on time, with an overall battery life of about 12-14 hours with moderate to heavy use. Not bad for such a tiny phone!

The Bad:
Non-removable Battery; it pains me to see that the battery is non-removable. This means that when the battery eventually loses its ability to hold a charge, you will have to either send the phone back to Unihertz for a battery replacement, or just replace the phone entirely. Since the phone is not a uni-body design, and is at a lower price point, I can't understand why we are not given the option to remove the back and pop in a new battery ourselves. To me, this is a major downfall of the Jelly 2 over the long term.

Hidden features:

Speaker Boost - Go to Settings > Sound > Advanced > Sound Enhancement; now toggle on "BesLoudness" to get a noticeable increase in speaker volume.

Face Unlock - Go to Settings > Security > Face Unlock (enter your pin) > Enroll Face; now let the camera familiarize itself with your face, and you now have the Face Unlock feature on your tiny smartphone!

Increase Keyboard Size - Go to settings > System > Languages & Input > Virtual Keyboard > Gboard > Preferences > Under "Layout", Select "Keyboard Height" > Choose "Extra Tall"; you have now maximized the size of the on-screen keyboard to allow for easier typing.

Overall, the Jelly 2 is a great little phone. It's powerful/speedy, has a decent camera, good call quality, great battery life and an adequate display for its size. It will do everything your larger smartphone will do in a smaller package. I do worry about the build quality with the aforementioned jiggly plastic buttons on the side. I also wish it had removable battery. But these are small gripes compared to the overall device. I'm glad I purchased the Jelly 2, and it has even become my daily driver for now! I look forward to seeing what Unihertz puts out next. Would highly recommend the Jelly 2!

best phone ever

I have this phone now over 2 year and I use it daily. This is how a proper, functional phone should be and look like. Battery life still is 2 days with normal use. The only sign of ware is the alu backstrip is a little loose, but that's really nothing to be bothered with
I honestly don't understand why there are only 10 reviews. I'm about to buy another one, just in case they stop producing it in the near future because there is no equal one available that is rugged, waterproof, small ( I had also the atom 2.4inch, but it's just to small for daily use)and ok performance. Keep it going uniherz!

Titan Slim perfect phone

Titan Slim - my perfect phone, being a big fan of the qwerty keyboard, I just love it. minuses - I didn't find anything, in fact the software update would be a minus, otherwise everything is ok.

Back to the future!

I tried Titan, Titan Pocket and finally SLIM version arrived. We are back to the future. Right dimension, perfect keyboard, fast and modern. The first real bb's heir. Well done!

The essential little kit

The nec Nothing to say it's perfect I already have the little Atom and the Titan this one is me ideal compromise.

5.0 out of 5 stars I love this phone

I've only had the Unihertz Atom L for a few days, but so far I'm LOVING it.

I love how small it is. I'm so sick of giant 6"+ slab phones that everyone makes these days. I wouldn't go any smaller than a 4 inch screen though. It doesn't give me any trouble that any other larger touchscreen wouldn't also give me, but any smaller, and I imagine it would.

This phone lasted over 60 hours before needing charged.

It's not the latest, greatest, fastest phone on the market by a long shot, but it is the smallest one with the best specs that won't cost as much as a used car, and for that, I'm grateful.

I can't possibly recommend this thing enough(unless you have large hands, then you'll probably hate how small it is). I hope this thing continues to work as it has, and I hope the company sticks around making small budget phones like this one for a LONG time.

I haven't tried playing any games on it, and I haven't had any issues requiring customer service, so I can't really comment on those things, but I have seen review videos with people playing games with this and the Jelly 2, which has essentially the same hardware, so it can definitely be done.

Update: it's now May 2022, and the only "issue" I have to report is for whatever reason it won't do the wireless update it keeps reminding me about once a week, but everything works perfectly. I really hope this company keeps making small rugged phones like this one because it's my favorite phone I've ever owned.

A good and practical phone that is rugged -Be careful on compatibility with cell twr updates

This UPDATES MY REVIEW. MARCH 2022, I used mine with Consumer Cellular. With a drop of 3G my phone worked on Data, but not did not process calling. CC and local reps at Target could not fix what they said to be a SIM card incompatibility. And that forced me to buy a sleazy new phone. I like my Atom L much better. Be wary of this problem and if anyone has better advice please provide info.

---------- Orig review -----------My first smart phone was a petite Atom which I liked. This continued to work following ocean immersion. As I became a heavier user I needed a larger phone with higher capacity battery. The Atom L met that requirement. Although a larger size it is still not too big and the larger screen, especially keyboard, is nice. It seems very rugged and has other added capabilities (over the Atom) such as SD card compatibility. The camera is very good. I use Consumer Cellular and some system settings had to be changed to download data with easy tech support of CU, I found a nice rotating clip case by Turtleback (for iPhone 5/5S/SE) that is a perfect fit (itemA-PMPVerSMExtHDL2). Other on-line reviews cover the phone in more detail. Overall a good practical phone that is not fragile. The owner manual is a bit too minimal. That should be improved.

An update a year later - still working fine with good battery life. Yesterday after dark dropped it off the end of a pier in sea water. Using a crab net I recovered it this AM and after a period it seemed to recover fine and tests our OK and seems to be fully functional again. I would buy this again. I think a good choice for heavy duty use where a basic, non-glitz, smart phone is the requirement.

small screen phone

it might be difficult to read the lcd for some people, I'm fine with the pixel size. I don't know how long this battery is gonna last, you can't replace the battery. I'm currently with mint mobile as the carrier. this camera has a 48 megapixel 8000x6000 jpg output. sometimes I can see screen burns, if I leave the color screen saver on it usually massage's it away.

It perfectly satisfy my demand!

Not the perfect phone but with every new phone being the size of a large stone tablet, this phone is a blessing. Camera is a little bad but I don’t use my phone camera often so meh. The back and open apps buttons at the bottom are light sensors not touch sensors so they don’t or barely function in the dark. Other than that the performance is awesome and the battery life is great. First smartphone I’ve owned that is actually comfortable in one hand.

Updated Review based on unit replaced by Unihertz themselves.

This phone is amazing. In all reality, the only con is the screen brightness in the sun, but I can deal. I've been using it for a month or so now alongside Tasker and Lightning Launcher Extreme and couldn't be happier.

-This phone is possibly the best phone I've ever had. The fact that it's unlocked gives it much more prestige.
-It is an incredibly snappy phone.
-It fits in my pocket and I can use it comfortably with one hand!
-The android update (Android 10) gives it great support with apps.
-Using it with the AT&T Bring Your Own Phone sim kit with Straight Talk and the service is awesome.
-The smaller screen may seem like a bad thing but you can binge Twitch, YouTube, playing games...anything for hours because the phone has less pixels to push AND it has a decent size battery (4300mAh).
-Speaker is nice and loud if you need it to be (usually I don't and have it at 50-75% even for alarms and such).
-The stock alarms are a great collection of birds chirping, water sounds and noticeable chimes.
-The device handles heat very well. Spent 3 hours driving with it mounted to the windshield while it was hot out and had no AC and the device didn't even slow down or drain extra battery while using the GPS.
-I've dropped the phone by accident a few times now and the phone hasn't seemed to be affected by it.
-The quick charge is another awesome thing with this phone AND it uses USB 3(I know a lot of phones have this, but still a great plus).
-I've already gotten used to the red "intelligent button" on the side and have switched around the actions a little to make using it easier for myself.
-The NFC chip is very quick as well.
-The Intelligent Assistant has a bunch of great things that give the phone greater quality of life changes such as the app blocker, which has 4 options for EVERY app (Boot Locker, Start Blocker, Background Blocker, and Background Cleanup). Definitely look into this part of the assistant if you want to maximize your battery life. (I can use my phone regularly for 3 days without having to charge.)
-I don't have any bluetooth or wifi issues.
-I haven't used the headphone jack or radio yet.

I really can't think of any notable cons. I absolutely love this phone. If this changes in the future, be sure I'll update my review once again.


perfect size fits pocket -Had no problems everyday use

Very good!

Really impressed with the device overall, the "on board" UHF analogue and DMR radio works really well - particularly for amateur radio and PMR. Only disappointment is the camera, which despite a phenomenal 48mp sensor is let down by poor software.


The ATOM XL I find that it is everything I like about it , not to big its rugged, to me its the perfect phone and does what I need and more.

Small, robust and good battery life....a great phone.

I wanted a smaller, robust phone and this ticks all the boxes. Mainstream phones have all increased significantly in size as people use them as a one stop media device. I needed to get away from the bulk of current phone offerings but still retain smartphone functionality. This coupled with a high quality, solid build and excellent battery life makes for a perfect day to day phone.

Make a name for yourself

As a single man, I am obviously always on the lookout for a woman. Well fellas, this is the mobile phone equivalent of owning a Chihuahua.

When I use it to pay, or scan a loyalty card, ladies coo over my tiny phone. I'm actually now recognised even in large supermarkets as the guy with the cute phone.

On a side note, it's a great phone, but who cares about performance eh?

Atom - Small & Rugged 4G Smartphone
Chris Bell (The Willman)
How nice to be able to have a small phone!

I love small stuff and to have a small phone that does nearly everything my large screen Pixel can do is fantastic. It's my main carry and with a PTT I also use it with ZELLO.

Screen is nice and clear albeit small, the feel in your hand is great and it seems quick too (down to the small screen?). I use mine mainly for calls and a pager with filtered SMS and emails directed to it (cheaper and way more useful than a proper pager and just as SMALL).

Overall I really like it but we'll see how it goes after reading some reviews where the rubber perishes.

It is expensive for what it is, but if you want small, other than the Unihertz Jelly there isn't anything else in its league.


Just what I was looking for

Perfect phone for me, the screen is small but fine if using swipe text, The size of the display stops my constant casual web browsing like on my old smartphone and limits me to looking at what I need to know. You can watch video no problem though. the NFC feature is really useful.
Battery life is good, I charged it overnight 13 hours ago, used it for 2.5 hours streaming music and texting and still have 50% left.
I love the size, so easy to fit in my pocket, I can stream my music while running and in the car etc no problem. at all, The usual Apps work fine so its reduced my smartphone use but kept me connected.
the IP68 rating is great for the beach life in Cornwall.
I did try the Nokia 800 tough before this but sent it back due to being so slow and glitchy, this phone is twice the price but worth every penny.

Awesome for arthritis sufferers

I LOVE my tiny smartphone

Fantastic fully featured phone but better as a second device IMHO as just too small for everything.

Superb little phone. One of my favourite phones ever and I've had a lot.
Not ideal if it's your only phone as you need perfect eyesight and typing is good so overall it's an amazing gadget.
Works very well as a bike navigation instead of a Garmin :)

It's fine

First off, never had a phone with an actual hardware keyboard until this one.

It's not mushy. It's more than fast enough for everything I want it for (even the occasional bit of graphically intensive gaming). The battery just keeps going - I use it heavily and it'll last at least a day and a half on a single charge. It's a surprisingly clean build of Android: there are minimal apps installed aside from the usual Google suite, a keyboard app that provides access to special characters and the like on screen, a "toolbox" app that's like a junk drawer of little utilities, and a notepad app. It's not the usual 75 pre-installed pieces of shovelware and carrier garbage.

The biggest issue is that a lot of Android apps assume a rectangular screen, this is very nearly square, and it screws with lots of stuff.

Next up is its size. It's earned the name Titan. It's big, it's thick, it's heavy. On the other hand, it also feels nearly indestructible, so...

All put, though, its downsides seem small.

It's big!

This is a very big phone. I should have looked into a Titan Pocket. I used to own a Blackberry classic. Therefore, I must have a physical keyboard on my phone. With the demise of Blackberry, this was the only alternative available. On the bright side, because it is driven by Android the App stores do not reject me, the way they used to when I owned the Blackberry. With the giant physical size comes a big screen as well. This is a great boon - makes browsing very easy. The Battery is large and as a result, lasts almost forever.
