Galaxy S25 Ultra Meets Note 20 Ultra: The Next Chapter of Note’s Legacy

Published

on

Samsung Galaxy S25 Ultra and Note 20 Ultra

The Galaxy S25 Ultra comes with a new look and powerful performance, which resembles years of evolution in Samsung’s flagship devices initiated by the Note 20 Ultra.

Samsung released the Note 20 series in 2020 and then discontinued the Note brand to only focus on the S-series flagships. The S21 series set a different identity for the S-series in the absence of a Note device.

In 2022, the South Korean phone maker shocked consumers with the S22 Ultra, an identical device to the Note 20 Ultra. The similarities between the two devices stands at the appearance. S22 Ultra had those sharp corners, curved screen and the same shiny frame as well as an S-Pen.

The S23 Ultra carried the same aesthetics with a high-resolution camera, new Snapdragon chip and better software support. The S24 Ultra removed the curved screen and adapted to a flat panel, ousting the curved screen from Samsung’s flagship for the first time.

The S25 Ultra has been revamped with a round corners, flat screen, low bezels for a brand-new Samsung experience. Yeah, Samsung’s flagship lineup has come so far ahead in the past four years, and it’s time that we give you a side by side comparison of these two devices.

Display

Both phones sport a 6.9-inch QHD+ Dynamic AMOLED 2X screens with punch hole. Note is fully rectangular with curved edges, and S25 Ultra brings rounded corners.

A side by side comparison shows, the Note 20 Ultra is larger due to its shape and frame, which is way more optimized in S25 Ultra. The new phone has adaptive refresh rate for efficient screen time.

The viewing experience is different in these two phones, the S25 Ultra shows better black and white pixels, while the non-reflective display coating makes improves the visibility compared to the glossy Note 20 Ultra.

Galaxy S25 Ultra vs Note 20 Ultra Display Comparison

Design

Here are the dimensions and weight details

  • Note 20 Ultra – 164.8mm height, 77.2mm width, 8.1mm thickness, and 208 grams weight
  • S25 Ultra – 162.8mm height, 77.6mm width, 8.2mm thickness, and 218 grams weight

Undoubtedly, the Note 20 Ultra has been one of the best devices with light weight. Even without a cover, this phone sits well in a hand and its adequate weight allows longer use.

S25 Ultra, on the other hand, sits on top of all the previously released Samsung flagships with its comfortable grip. Those round corners make it easy to operate with one hand, which is a bit tricky in an angular frame.

Among a few notable changes, the Note 20 Ultra has a sim card tray on the top side, including an SD card slot. Expandable storage was removed from new devices.

Battery

The Note 20 Ultra has 4,500mAh and the S25 Ultra packs a 5,000mAh battery, and it’s disappointing to see Samsung increased the capacity only slightly throughout these years. It’s one aspect of the new device which I criticized the most, and it should have been least 5,500mAh in the new model.

That said, the battery life was pretty good in the Note 20 Ultra when it was unboxed. As of today, the phone boasts a full-day battery life if you are not doing much of the internet of things, but the battery performance has declined.

The S25 Ultra looks very promising, and the new chipset has enabled more power efficiency, taking this device for more than a day of usage. To be mentioned, the new device supports 45W and the old device has 25W max charging.

Performance

The Galaxy Note 20 Ultra was launched with two chipsets – Exynos 990 (global) and Snapdragon 865+ (North America). My Note has Exynos processor, and It still performs pretty well with all the latest apps and games.

But, S25 Ultra has a whole new level of performance featuring Snapdragon 8 Elite chipset for all customers. Here’s Geekbench comparison.

Note 20 Ultra

  • Single-Core = 791 points
  • Multi-Core  = 2460 points

The new device is ahead on single-core score with 2205 additional points (278.89%) and 7071 (287.44%) points in multi-core.

We’ve also compared the S25 Ultra, S24 Ultra and S23 Ultra, check their performance difference here.

Based on my hands-on experience, the difference between the touch and responsiveness noticeable in the new model.

Software

The Note 20 Ultra unpacked with Android 10-based One UI 2.x and currently running One UI 5 (Android 13), released in 2023. The phone is still operational without any problem and receives occasional security patches.

Galaxy S25 Ultra comes with One UI 7, Samsung’s latest software with fluid animations, better UI, and many new AI features. Each touch interaction on this phone counts, and the responsiveness is on the next level. It has seven years of software support.

Camera

Note 20 Ultra was my first high-quality camera device with a 108 megapixel lens, which outputs amazing photographs and videos. The selfies on this device still look better in the majority of scenarios, including the portrait shots.

Taking this legacy forward, the S25 Ultra has the new 200MP camera and its default camera resolution captures brighter images and videos compared to the S24 Ultra. Features such as AI filters and Log video give you more control over the pictures and video properties for post-production.

S-Pen

The Note Legacy is all about its S-Pen and Samsung has taken a good care of this accessory by keeping it same and making it more energy efficient by removing its air gestures in the latest phone. However, you can still use them in the old device.

Conclusion

Samsung’s Note 20 Ultra was a great device, with years of development, Samsung has polished all smartphone technologies and feed them into the Galaxy S25 Ultra.

If you have any questions about any of these two devices, please share them via X or Facebook.

Galaxy AI features unavailable for Global users – Social Composer, Ask AI, Touch Assistant, and Samsung Assistant

Published

on

By

Samsung Galaxy AI

Galaxy AI is the richest mobile AI feature among premium phones. However, Samsung has some China-exclusive Galaxy AI features that are not available for Global users, including Social Composer, Ask AI, Touch Assistant, and Samsung Assistant.

While these tools enhance user experience, not all seem suited for global markets, especially Social Composer. Galaxy AI is packed with innovative tools, but their availability varies by region, as these are exclusive to China, via FragmentedChicken.

Social Composer (Writing Assist)

Social Composer uses AI to create social media posts from images.

Exclusive to China, it aims to simplify content creation. However, it might produce bland or awkward posts, similar to other AI-generated content. Many believe global users are better off without it.

Samsung Assistant

Samsung Assistant offers practical tools like a “clipboard assistant” that suggests actions for copied text, such as translating or searching. Its “app return assistant” and “feature suggestion assistant” also boost efficiency.

Ask AI (Gemini)

Samsung’s Ask AI is a chatbot that answers questions using web data. Since Google Gemini powers similar features globally, Ask AI fills the gap in China, where Google services are limited, so this makes its exclusivity understandable.

Touch Assistant (Circle to Search)

Touch Assistant processes on-screen text to improve reading efficiency, similar to the global Circle to Search feature. Exclusive to China, it’s likely duplicative elsewhere, explaining why Samsung hasn’t rolled it out globally.

Samsung One UI 7’s Audio Eraser is the Object Eraser of sound

Published

on

By

One UI Audio Eraser

Samsung Audio Eraser, introduced in the Galaxy S25 series, solves the problem of unwanted noise from videos by reducing background noise and enhancing desired sounds. This feature mirrors the Object Eraser feature, launched with the Galaxy S21.

One UI 7’s Audio Eraser allows users to adjust video audio by removing unwanted sounds and highlighting what matters. It scans videos to detect and separate sounds, working on both user-recorded clips and shared videos.

Samsung’s AI Solution Team at Samsung Research built Audio Eraser by collecting diverse audio data. They simulated real-world scenarios and recorded sounds like wind in the field.

“Wind was tough,” said Hejung Yang. “We even recorded outdoors on windy weekends.”

The team reviewed thousands of audio samples weekly to perfect the sound separation model. “Each developer analyzed over 1,000 samples under different conditions,” said Jiwon Kim.

Audio Eraser runs on-device, enabling real-time editing and better privacy. “We focused on fast, low-power AI models,” said Hosang Sung. Samsung’s expertise in on-device AI helped optimize Audio Eraser for smooth performance.

Samsung Research and the MX Business collaborated to ensure smooth playback during video and audio editing. Staff from both departments have also optimized processing for videos longer than an hour.

Audio Eraser identifies six sound types: voices, music, wind, nature sounds, crowd noise, and ambient noise. Here’s how it works:

  • Using sound source detection, it pinpoints where sounds occur in a video.
  • Sound source separation then isolates and categorizes each sound for precise editing.

“We’re committed to next-generation solutions,” said Hoonyoung Cho, Vice President at Samsung Research. Galaxy AI will continue to evolve with intuitive features.

Reminder: Samsung Galaxy S21 series will get One UI 7 (Android 15) update

Published

Samsung Galaxy S21 Ultra One UI 7

If you own a Samsung Galaxy S21, S21+, S21 Ultra, or even the S21 FE, here’s some good news: your device is eligible for the Android 15-based One UI 7 update. This article covers what you need to know about the major OS upgrade for your device.

Samsung has officially confirmed that the Galaxy S21 series will receive the Android 15-based One UI 7 update. Launched in 2021 with Android 11, these devices are promised four major OS updates, making One UI 7 the final one.

Unlike the Galaxy S24 and S23 series, the Galaxy S22 and S21 lineups aren’t part of the One UI 7 Beta Program. Therefore, the Galaxy S21 and S22 smartphone users will get the stable version directly, ensuring a reliable user experience.

Notably, One UI 7 marks the final major OS update for the S21 series. After Android 15, the South Korean tech giant will only provide new security patch updates until 2026, based on its five-year security update policy for these devices.

Samsung Galaxy S21 Ultra One UI 7

Compared to the Galaxy S24 or S23 owners, Galaxy S21 users seem less active in discussing One UI 7. Since it’s their last major update and there’s no Beta Program access, users are patiently waiting for the stable update release.

The stable One UI 7 rollout is beginning in April for newer devices like the Galaxy S24 series, the Z Flip 6, and the Z Fold 6. For the S21 series, the update is scheduled for May 2025, though timelines may vary by region and carrier.

One UI 7 update brings revamped visuals, smoother animations, and enhanced multitasking. Some Galaxy AI features, like improved photo editing, may be included, but older hardware might limit advanced functionalities.

One UI 8 is Samsung’s next big software update, built on Google’s Android 16. It’s set to bring some slick tweaks to your phone’s look and feel, though don’t expect a total overhaul. From what’s been floating around, Samsung’s focusing on refining the experience—think smoother animations, small app design updates (like a fresher Gallery and My Files), and whatever Android 16 features Google’s cooking up. I’m personally hoping for some noticeable performance boosts because who doesn’t want their phone to feel like it’s new?

When’s Android 16 and One UI 8 Coming?

Here’s where things get exciting but also a bit speculative. Google’s reportedly speeding up Android 16’s release, possibly dropping it as early as June or July 2025. That’s way ahead of the usual October timeline. Samsung, not wanting to be left in the dust, might launch One UI 8 around the same time, especially with their next foldables—the Galaxy Z Fold 7 and Z Flip 7—expected to debut in July or August 2025.

For other devices, like the Galaxy S25 or S24 series, the rollout could start a bit later, maybe in August or September, with beta testing possibly kicking off in June for the S25 users. This is all based on rumors and reports, though, so take it with a grain of salt. Samsung hasn’t dropped an official date yet, but the idea of getting Android 16 this early has me pumped.

Why Was One UI 7 Delayed?

Now, let’s talk about One UI 7’s messy rollout. If you’ve been waiting for Android 15 on your Galaxy, you probably felt the frustration. Samsung kicked off the One UI 7 beta in December 2024, but the stable version didn’t start rolling out until April 7, 2025—six months after Google finalized Android 15.

Things got worse when Samsung had to pause the rollout just days later due to a nasty bug that locked some Exynos-powered Galaxy S24 phones. They fixed it and resumed on April 15, but the damage was done—fans were not happy. I’ve been through enough buggy updates to know how annoying that is. Imagine updating your phone only to get stuck at the lock screen. No thanks

Samsung has learned from this, though, and reports suggest the company is working to make One UI 8’s launch smoother. Samsung has already started internal testing, which is a good sign that the company is trying to avoid another fiasco.

Why Should You Care?

One UI 8 could be a game-changer, especially if Samsung nails the timing. Getting Android 16 on your phone just a month or two after Google’s release would be a first for Samsung, which usually trails behind Pixel phones. Plus, with the Galaxy Z Fold 7 and Z Flip 7 potentially launching with One UI 8, it’s a big moment for foldable fans. I’ve always been curious about foldables, but I’m waiting for the software to feel as polished as my daily driver Galaxy S device.

If you’re wondering whether your device is eligible or when you’ll see One UI 8, keep an eye on Samsung’s official channels or the Samsung Members app for updates. For now, check your phone’s software update section to make sure you’re on One UI 7—devices stuck on older versions might have a tougher time jumping to One UI 8.

Samsung should be more transparent about its software updates

Published

on

Transparent Samsung

Samsung is the largest Android device ecosystem partner and the biggest smartphone seller around the globe, but its software updates and rollout needs to be more transparent than the current version.

The situation around One UI 7 is the perfect example and how this low-transparency is making a massive impact on the company’s brand value despite improving a lot.

Samsung has been conducting beta testing for years, but the One UI 7.0 is an unusual move to its past practices. The One UI 7 beta began in December, this is quite late compared to One UI 6 beta in August 2023.

The new One UI comes with interesting changes and UI upgrades and features. The animations are smoothened for a better user experience, and these changes becomes more obvious with hands-on experience.

The hype around this software has led to a mass speculation on its final release because Samsung hasn’t shared an official One UI 7 rollout date. The wait extended through January, February, and then March, in which, it announced the schedule for different countries.

This might look like a regular rollout practice, but you need to understand its mysteriousness. It’s not about the wait for a rollout, it’s about the wait for the rollout date announcement when the testing is overstretched.

Samsung users have been waiting for a major OS upgrade through 2024, but the update delayed to 2025. In this case, the company should’ve come up with a clear statement on this matter to clear users’ doubts. Instead, it went full silent after launching a beta program in December.

At Unpacked 2025, Samsung unveiled the S25 series with One UI 7, but there wasn’t a mention of older devices. It did leave some clues about One UI 7 for previous devices via press-releases footnotes, which might have been left unchecked by readers.

Why transparency is important

Samsung devices are getting more software focused. For example, the Galaxy AI project is deeply based on the One UI software and the new S25 series is labeled as AI rich phones.

Most of the device ecosystems are made of their existing users and Samsung is no different. For example, the S24 series, the company has sold millions of smartphones around the world, and it’s also the first to receive beta software.

This hype around the software has kept the majority of the users waiting for the official release, and the lack of information about a rollout date has made the situation worse. Only if Samsung could have been more transparent about the delay or an amended software updates schedule, it would make a big difference rather than being completely blank on the surface.

Solutions

Samsung has a large online community, including its dedicated forums. It should appoint some moderators that keep the community posted about the rollout progress, and it must not be exclusive to only one country.

The Korean tech company should leverage the power of social media to share rollouts and new updates information. This is a great way to stay connected with users who follow its social media accounts and raise awareness about the company’s latest move.

That includes critical bugs and software issues for a device (or devices) that could disturb the user experience and guidance to users. Users can provide an instant feedback on various issues that isn’t possible on forum.
