A great phone just a little bit better than 2025s
[This review was collected as part of a promotion.] I am blown away by how good Samsungs are. They are by far the best android phone. If you’re wondering why you should sell a kidney for this device, here’s the breakdown: 1) Privacy display - I no longer need a screen protector to block prying eyes on my train commute. 2)the best phone camera I have ever owned, I no longer use an SLR 3)An AI assistant at your fingertips 4) Battery to last a day and a bit more I am in love with this phone and have even had to buy the wife one because she loves how great mine is. I bought black but im envious of her violet colour!

So glad I upgraded- my S26 Ultra
[This review was collected as part of a promotion.] I’ve been using the Samsung Galaxy - S26 Ultra for a little while now - honestly, it’s lived up to the hype. The first thing I noticed was how much better it feels in my hand - it’s big, but it’s still comfortable to hold all day. The camera is my one of my favorite part - I took it out for some night shots recently and the detail is amazing. It picks up colors in the dark that my old phone would have missed - it's really impressive compared to my s24. The new privacy screen is also great for when I'm out - knowing people can't see my screen from the side makes a big difference. Everything about it is fast, there's no lag even when I’m using a lot of apps. The battery lasts a long time even when I'm busy with video streaming or games, it's nice not needing a charger by lunch. The S Pen is also great for writing quick notes on the go - it's just a really good, high-quality phone that feels worth it.

Like always - great phone
[This review was collected as part of a promotion.] Just got my hands on the Samsung Galaxy S26 and honestly, I love it. The phone feels super fast — apps open instantly, scrolling is smooth, and even games run without a hitch. The screen is bright, clear, and perfect for watching videos or just browsing. I also like the little software features Samsung added; they make life easier without being annoying. Battery life is solid — I can go all day without stressing about charging. Plus, the phone is really comfortable to hold and feels premium, but not fragile. The camera? Amazing. Photos are sharp, colors pop, and low-light shots actually look good. Honestly, for me, this phone just works, looks good, and makes daily life easier. If you want a reliable, smooth, and nice-looking phone, the S26 is a really good pick.

The best device I have used thus far.
[This review was collected as part of a promotion.] Samsung Galaxy S26 Ultra in the Cobalt Violet colour is probably the most powerful and versatile phone I have used so far. The build quality is excellent with softened corners making it comfortable to hold even with a large footprint, and the 214g weight helps to reduced fatigue. The display is the strongest point in my view with a 6.9-inch Dynamic AMOLED screen that provides 2600 Nits in bright sunlight.. the world‑first built‑in Privacy Display is great for commuting or public spaces and the anti‑reflective coating further improves outdoor visibility and durability. My notable favourite is the 200 MP wide (f/1.4) lens, the 50 MP ultrawide and the 50 MP zoom telephoto lens (5× optical), I am really enjoying using the camera, and my expensive rangefinder camera is now taking a back seat. The Nightography Video delivers brighter, clearer low‑light footage with a wider aperture. The AI‑powered Photo Assist allows natural‑language edits — a standout convenience feature. I have used this phone a lot now and it charges quickly with the 60W fast charger. The Snapdragon Elite 8 should be an awesome processor, but I have not run any advanced AI features on it yet. Will post further experiences soon. Overall, this is a superior performer than any other phone i have used thus far. The ergonomics are outstanding, the display is gorgeous and performant in bright sunlight and the 120Hz screen refresh makes it divine for streaming content and playing games. The camera features, the quality of lenses and the AI features provide sublime images and 8K video.

The Privacy Display is a genuine game changer
[This review was collected as part of a promotion.] I’ve been using the S26 Ultra in blue for a few weeks now, and while the hardware is a nice refinement, the new Flex Magic Pixel (the privacy screen) is what actually won me over. I was sceptical at first, but it’s been incredibly helpful for my daily commute. On the train, I can tilt the phone slightly and the screen looks completely black to the person sitting next to me. I love that I can set it to turn on automatically only for specific apps. I have mine set for my banking apps and my work email. It's so much better than those plastic screen protectors that make the display look grainy all the time. The design feels a bit more refined this year; it’s noticeably lighter and the slightly more rounded edges make it much more comfortable to hold during long sessions compared to previous Ultras. The new 60W charging is also a massive step up; I can get a significant charge in about 20 minutes while I’m getting ready in the morning. If you value your privacy in public spaces or just want a flagship that’s a bit more ergonomic, this is a fantastic choice.

Amazing Upgrade
[This review was collected as part of a promotion.] I upgraded from the Samsung Galaxy Z Flip 7 to the Samsung Galaxy S26 Ultra in blue, and I honestly didn’t expect the difference to be as big as it is but I’ve absolutely loved it so far. The first thing I noticed is how premium and solid the phone feels compared to the Flip. It’s sleek, well-balanced, and still comfortable to use despite being a larger device. The blue colour looks incredible in person really clean and slightly understated, but still stands out. The display is a big upgrade for me. It’s bright, sharp, and just feels smoother overall. Everything from scrolling to watching videos feels effortless, and the size makes it much more practical for everyday use without feeling bulky. The camera is easily one of the best parts of this phone. It’s simple to use but produces really high-quality photos, whether that’s in normal lighting or low light with the Nightography features. The ultra-wide shots are great, and video is super steady which is ideal for capturing moments on the go. The AI editing tools are a great addition too, especially being able to remove or adjust things in photos without needing extra apps. Performance wise, the phone feels fast and responsive with everything I’ve thrown at it so far. It just works without any lag, and everything feels smooth and refined. Battery life has also been solid easily lasting through the day without any issues. What I really like are the smaller details things like the photo editing, overall usability, and how intuitive everything feels. Samsung has clearly put a lot of thought into the AI features, and it makes the phone feel more future-proof rather than just a standard upgrade. Overall, moving from the Flip to the S26 Ultra feels like a massive step up. It’s a powerful, polished phone that’s easy to use, packed with useful features, and genuinely enjoyable day to day. I’m really happy with the upgrade.

Captured on the Move: My First Week with S26 Ultra
[This review was collected as part of a promotion.] I’ve been using the Samsung Galaxy S26 Ultra for just under a week now, and it’s been seriously impressive from the start. It feels quick, smooth and well refined, whether I’m navigating, switching between apps or using it throughout the day on the move. It also sits nicely in the hand, and even with a Spigen case it doesn’t feel overly heavy compared to my previous S20 FE. Getting set up was straightforward too — transferring my data and apps using Smart Switch was quick and easy. The camera is a real standout. It’s consistently sharp and reliable, even in busy scenes and mixed lighting. I’ve been using it while in Paris and it’s handled everything well, from zooming in for detailed shots to using the wider aperture for more depth and low-light scenes. You can just point and shoot and trust the result. What really sets it apart though are the AI features. I’ve been experimenting with editing some of my Paris photos, including removing tourists around the Arc de Triomphe and along the Champs-Élysées, and the results have been surprisingly strong. It’s intuitive, quick to use, and enhances images in a natural way without overdoing it. Also worth noting the stylus make sure it’s fully seated, as I once hadn’t pushed it all the way in and it didn’t click back in straight away. Battery life has also been solid, comfortably lasting through a full day of regular use including camera, apps and browsing. I’m looking forward to exploring more of the advanced features as I continue using it, but first impressions are very strong. Overall, the S26 Ultra feels like a properly refined device — powerful, reliable, and with AI features that genuinely improve the experience.

Ultra in every sense of the word
[This review was collected as part of a promotion.] Received my new Samsung Ultra S26 on the official release date as promised when preordering and was surprised how minimalistic the packaging is the phone comes in. Phone screen was bigger than I expected and setting up was a breeze, I used the included usb-c cable and uses the transfer wizard on the S26 Ultra to copy my data from my old pixel phone to the Ultra which took less than 30 minutes with over 110gb of data being moved to new phone. Once setup I got to start playing around with some of the new features including the privacy display which comes in very hand when you want to keep prying eyes away when typing in sensitive information such as passwords and surprisingly works very well. The camera is pretty stand out offering decent quality pictures even when using the higher zoom options up to 100x! I also love that the built in ai features offering powerful editing functions in photos that have been taken including erasing people or backgrounds from photos or making small corrections. Battery life has been great easily lasting a whole day with a lot of usage. overall I am very impressed with this latest Samsung model and wouldn't hesitate to recommend to others.

Good product, works as intended.
[This review was collected as part of a promotion.] Good phone. Does exactly what is expected. Noticeable increase in speed compared to my previous phone (note 10+) and built in AI features have been good to use (remove object from photo is a great feature and makes even the worst photo bomber irrelevant). battery life is good. I watch a lot of you tube/prime content and have not had any issues with the battery life. Superfast charging is great as well. Display is good for videos.
