Smartphones with a QWERTY keyboard are a rare sight in 2022. Once upon a time, thanks to Nokia and BlackBerry, they were the toast of the world. That time is past. But a small, dedicated set of mobile phone users still swear by hardware QWERTY keyboards. This Unihertz Titan Slim review will appeal to this set of users.

Unihertz Titan Slim has a candy bar QWERTY form factor, like the BlackBerry Keyone and KEY2 range. That is to say, it is a touchscreen-based Android smartphone with a portrait-oriented, fixed hardware keyboard. It is a slim version of the older Unihertz Titan.

One very important question, though, is: Does anyone still want this form factor in 2022? Apparently. Unihertz ran a Kickstarter campaign to raise HK$ 392,476 for the Titan Slim and raised a whopping HK$ 4,598,276 instead from backers. It looks like quite a number of people are interested.


The Titan Slim has a 4.2-inch touchscreen display with a 768×1280 pixel resolution, below which is located the hardware QWERTY keyboard. This is a 4G LTE, dual SIM phone running Android 11. It is powered by a fairly dated entry-level Helio P70 chipset. Things get better with the 6 GB RAM and 128 GB built-in storage. There is no external memory option.

For photography and video capture, we have an 8 MP front camera and a 48 MP rear camera. The fingerprint scanner is built into a touchpad at the top of the hardware keyboard. The touchpad doubles as a Home key. Push it while anywhere, and the phone returns to the home screen.

The last major specifications include the 4100 mAh battery. The specs make it clear that this is not a power-horse. The entry-level processor paints a good picture of what to expect. It makes the Titan Slim slightly less powerful than the BlackBerry Key2 from 2018.

As soon as our review unit arrived from Unihertz, we pried it open like excited kids with a new toy. In the box, we found a screen protector and a SIM card ejector. Then the phone itself which already had a phone case and thin film screen protector on. Also in the box were a 10W charging block, a USB-C charging cable, an earphone jack adapter, and lastly, a warranty card. 


We have had the Titan Slim for over two weeks now, and if you were ever a Blackberry lover, you can’t help that nostalgic feeling when looking at the Titan Slim. The phone reels you in at the first glance, thanks to the comeback of the QWERTY physical keyboard.

The Titan Slim is narrow and tall (which is where the name “Slim” is derived). But it is also thick, and many people will find that an irony, considering the name. Everyone of us who handled it out of the box were not expecting the thickness. But some thought appears to have gone into the design, because the chunkiness does not make it feel uncomfortable in use. On the contrary, the phone provides a smooth, even, and light grip which makes it enjoyable to hold. We imagine that the thin and tall aspect ratio is where the magic is.

The back panel of the has a glossy, plastic finish. The plastic finish is quite solid. The front of the phone is glass and the sides have a plastic frame. There is also The QWERTY physical keyboard that is almost an exact replica of a Blackberry. The display is 4.2 inches in size and uses IPS LCD technology. The phone has only 60Hz refresh rate, but that doesn’t take away from how good the display is. Once we took off the pre-applied screen protector film, gosh! Beautiful.

The Titan Slim has an infrared blaster located at the top of the phone, a good location for pointing it at your TV, a/c, or other device you wish to control with it. There is a built-in remote controller app. I am familiar with using these. Setting it up to control the LG DVD player in my study wasn’t difficult.

This is a dual-SIM smartphone. Contrary to what we see mostly, there are two separate SIM card slots and trays, instead of one slot and tray that houses both SIMs. There must be a practical reason why this was done. Below the SIM slots, which are located on the left side of the phone, is a red button that serves to turn on and off the LED light at the back of the phone for use as a flashlight in the dark. On the right side of the Titan Slim are the volume and power buttons.

Unihertz have gone with Apple and Samsung, and not included a 3.5mm audio port here. You can use the adaptor in the box to connect an audio headset, though. At the top right section of the phone is an LED notification light. It has been a while we saw one last on a phone.

Now, let’s talk about the hardware QWERTY keyboard, which is the main selling point of this device. The keys are small and take some getting used to. You enter special characters by tapping a bar at the bottom of the screen, right above the keyboard, to select the character you need. The keys are backlit.

Above the keyboard is a touch navigation bar. That is where the fingerprint scanner is located too. Tap/press it to return to the home screen. Press and hold to activate Google Assistant. It is a functional feature that you will use a lot.


The TItan Slim runs stock Android OS which looks good. It came with version 11 out of the box. We checked and there was no Android 12 update waiting for it. So, we asked Unihertz whether it was in the works, and they replied that it will be updated in the future. Sorry; we have no timeline.


This is a dual SIM 4G phone. It supports the nano SIM card standard. Using mobile data on it is without issues. It holds on to a signal well. Connecting to Wifi networks have been without issues.


In-call audio is solid – one of the better ones out there. Voices are clear at both ends. Music playback over the built-in loudspeaker is just fine; It is nothing fantastic, and nothing that will have you tearing your hair out. The speaker audio is noticeably hollow. Watching video on the display is a pleasant experience. And, yes; you can watch in landscape mode, which is the better way.

Camera, photography, and video recording

The single camera on the back of the Titan Slim is a 48 MP sensor, while there is an 8 MP unit in the front. The camera is neither spectacular nor terrible. You be the judge by taking a look at some sample photographs taken with the Titan Slim.

Sometimes, the pictures are not very sharp, especially the front camera but it does a decent job. This is for both the front and back cameras. But, again this is normal behaviour for cameras at this price point, so don’t take it too personally. The video recording supports 1080p@30fps. 


We were apprehensive about the Helio P70 chipset powering the Titan Slim. Why? It is a few years old and not exactly a powerhorse. But after using the Titan Slim for days, it occurred to us that we hadn’t experienced a hiccup yet. The phone has gone on working without us getting frustrated with its performance. Interesting. Did Unihertz do some optimization work to make this happen, or is it only due to the fact that the 4.2-inch display puts little strain on the processor? Whatever it is, performance has been smooth, and we love it.


Battery life is one of the areas that the Titan Slim shines brightly. Pairing a 4.2-inch display with a Helio P70 chipset and a 4100mAh battery is the perfect recipe for long battery life. And that is exactly what we got, in our use. The included charger is a 10W piece, so you get slightly faster charging than regular.

Our Verdict

Unihertz Titan Slim review: An interesting phone for those who must have a QWERTY keyboard

The Unihertz Titan Slim is a decent smartphone that gets the job done. It offers some uncommon features, like an IR blaster, hardware flashlight key, and a versatile QWERTY keyboard. At the end of the day, that keyboard is its defining feature.

This phone is clearly targeted at those who must use a physical QWERTY keyboard – which is mostly people who are sad that BlackBerry phones are no more and still long for that keyboard experience. It is a small niche of the smartphone market, but it exists, and it is good to see a manufacturer cater to them.

If you belong in that niche, this phone will appeal to you. If you don’t, nothing we say about it will. If you want a candy bar Android smartphone with a physical QWERTY keyboard, Unihertz Titan Slim is as good as it gets today. It has everything you need and does what you need it to do.
