Review by Jon Donnis
The smartphone market has spent years moving in one direction. Bigger screens, more apps, more notifications, and more demands on our attention. At the same time, traditional feature phones have remained available for those who want a simpler experience, but often at the cost of losing access to many of the services people now rely on every day.
The TTFone TT990 attempts to sit somewhere between those two worlds.
After spending the past week using the device as both a smartphone and a traditional flip phone, it quickly became clear that the TT990 is not trying to compete with flagship handsets. Instead, it is trying to solve a different problem entirely. It is aimed at people who want to remain connected without carrying around a device that constantly encourages endless scrolling, social media browsing and digital distraction.
As somebody who remembers the early days of mobile phones, the flip phone era, and the eventual shift to smartphones, I found the TT990 to be a genuinely interesting proposition. It takes a familiar form factor and combines it with just enough modern functionality to remain practical in everyday life.
The first thing that stands out is the build quality. The phone feels solid in the hand and well put together. The hinge feels sturdy, the casing feels durable, and the physical buttons are satisfying to use. There is a reassuring sense that this is a device built for everyday use rather than something fragile that needs constant protection.
The dual-screen arrangement works surprisingly well. The 3.5-inch internal touchscreen is naturally lower resolution than a modern smartphone display, but it is perfectly adequate for the type of tasks this phone is designed to handle. Reading messages, checking contacts, making calls and using essential applications all feel comfortable enough. It is important to remember that the TT990 is not intended to be a media consumption device. Nobody is buying this phone to spend hours watching YouTube or binge-watching Netflix.
Performance throughout testing was also better than expected. The touchscreen responds well, navigation feels smooth, and the phone generally feels quick and responsive. With 4GB of RAM and 64GB of internal storage, there is plenty of room for everyday use, and the addition of MicroSD support up to 256GB provides further flexibility for those who need extra space.
One of the biggest questions surrounding a device like this is app support. The TT990 runs a de-Googled version of Android 14 and uses the Aurora Store for applications. Essential communication apps are available, including WhatsApp and Viber, allowing users to send messages, make voice calls and conduct video calls without issue. I was pleasantly surprised to find Telegram available as well, which will likely appeal to users who place a greater emphasis on privacy-focused communication.
Another pleasant surprise came when testing banking software. I expected compatibility issues, particularly given the absence of Google's services, but my banking app worked without any problems. That alone may remove a major concern for potential buyers considering a move away from a conventional smartphone. (I only tested with Nationwide)
Call quality was excellent throughout testing. Connections were reliable, voices sounded clear, and network performance presented no obvious issues. At its core, the TT990 succeeds at the most fundamental task any phone should perform. Making and receiving calls is straightforward and dependable.

The camera is perhaps best described as functional. The 8-megapixel rear camera produces acceptable results for quick photographs and everyday snapshots, but those expecting smartphone-level photography will naturally be disappointed. Given the intended purpose of the device this is understandable, although I would still have preferred a higher resolution sensor.
Battery life is another area where the TT990 performs well. The advertised standby figures proved realistic during testing. With light use I was able to leave the phone running for three days while still having battery life remaining. Naturally, heavier use of apps and communication features will reduce those figures, but overall endurance is impressive compared with many modern smartphones.
A feature I particularly appreciated was the included charging cradle. It is a simple addition, yet one that adds convenience and reinforces the phone's user-friendly design philosophy. Rather than fumbling with cables every time the battery needs charging, you simply place the phone into the dock. It is a small touch, but a welcome one.
Unfortunately, the TT990 is not without its shortcomings.
My biggest criticism concerns the absence of T9 predictive text. The phone relies on the traditional multi-tap ABC input method when using the physical keypad. That means pressing the same key multiple times to cycle through letters. For some users this may not seem significant, but for those of us who grew up using T9, its omission feels like a major oversight.
T9 remains one of the fastest text entry systems ever created for physical keypads. In many situations it can even outperform touchscreen typing. Given the target audience for the TT990, the lack of predictive text support is difficult to understand and will undoubtedly frustrate some users. I found myself naturally using the onscreen keyboard, which works as it would on a regular smartphone, but because you are working on a 3.5" screen, it can be a bit tricky when typing if you have bigger fingers.
I also encountered an issue after installing Viber. The application took control of the green call button on the physical keypad. Instead of opening the standard phone dialler, pressing the button launched Viber. More frustratingly, there appears to be no simple way to restore the original behaviour without performing a factory reset. This will not affect users who do not install Viber, but it is still an issue that needs addressing. I reported the problem to TTFone and hopefully a future software update will resolve it.
Users attempting to treat the TT990 as a conventional smartphone may encounter other limitations. Typing using the on-screen keyboard can feel cramped, and the compact display makes longer sessions of smartphone-style use less comfortable. In truth, however, that is somewhat missing the point of the device.
App compatibility can also be inconsistent due to the de-Googled nature of the operating system. Applications that depend heavily on Google services may not function correctly. YouTube is one notable example. While alternative clients have previously offered workarounds (NewPipe), upcoming changes to Google's systems have created additional complications moving forward.
The reality is that the TT990 works best when approached as a modern flip phone rather than a miniature smartphone. It excels when used for calls, messages, video calls and essential communication. It struggles when asked to become a full replacement for a modern Android handset.
That distinction is important because many criticisms disappear once you understand what the phone is trying to achieve. The TT990 is not designed to keep you glued to a screen. It is not built for endless social media browsing, video streaming or constant online engagement. Instead, it focuses on delivering the essentials while still providing access to the modern services many people genuinely need.
For many users, WhatsApp has effectively replaced SMS messaging. Being able to access that alongside traditional calling features makes the TT990 far more practical than many older feature phones.
What impressed me most is that TTFone appears to understand its audience. The company has consistently listened to customer feedback and refined its devices over time. The TT990 feels like another step in that process, an attempt to find the sweet spot between simplicity and modern functionality.
Is it perfect? Certainly not. The absence of T9 predictive text alone will be enough to irritate some users. There are also inevitable compromises that come with choosing a device designed around digital minimalism.
I also gave the TT990 to my 76-year-old father to try. The main problem he encountered was that he had never used a phone with a physical keypad before, for texting. He only started using a smartphone around five years ago, so he is completely accustomed to touchscreen keyboards. As a result, learning the multi-tap system on the physical keypad proved more hassle than it was worth for him, while the on-screen keyboard was simply too small to use comfortably.
That said, he mainly used the phone for video calls with family abroad, as well as regular voice calls. However, he accessed all of these functions through the touchscreen rather than the physical keypad. Another issue arose during video calls. My father does not like holding a phone for long periods and usually props it up against a cup or whatever happens to be nearby. This is where the included charging cradle should have been particularly useful. Unfortunately, when the phone is placed in the cradle and opened, the selfie camera points slightly downwards. I can imagine that a revised cradle design, or a hinge that allowed the phone to open completely flat, would make video calling much more comfortable for users like my father.
Regardless there is something refreshing about a phone that actively encourages you to spend less time staring at it.
Personally, the TT990 will not replace my primary smartphone. My work requires the full capabilities of a modern device every day. However, I can easily see myself reaching for the TT990 when meeting friends, taking a break from work, or simply wanting to disconnect from the constant noise that comes with carrying a fully featured smartphone.
In many ways, that is where the TT990 makes its strongest case. It offers a practical alternative for people who want greater control over their relationship with technology without abandoning modern communication entirely.
The TTFone TT990 is a thoughtful and well-executed hybrid device that successfully bridges the gap between traditional flip phones and modern smartphones. It gets the fundamentals right, delivers excellent battery life, offers access to key communication apps, and wraps everything in a durable and familiar design.
There is room for improvement, particularly regarding predictive text support and a handful of software quirks, but there is also a great deal to like.
For anyone looking to reduce digital distractions while remaining connected to the people who matter most, the TT990 deserves serious consideration.
Score: 8 out of 10
The TTfone TT990 4G is out now at
Also worth mentioning, is that the phone does have a programmable SOS button, so one press will call a designated number. And it is also compatible with most hearing aids too, so if you are an older user, these are some features that may appeal to you.
Thanks to TTFone for providing the phone for review.
