Key differences between Galaxy S25 Ultra and Galaxy S24 Ultra
Recently, Samsung unveiled its latest flagship smartphone lineup – the Galaxy S25 series. Out of these, the Samsung Galaxy S25 Ultra may be the leading Android phone of 2025, but it doesn’t have as many upgrades as you would have expected compared to the existing Galaxy S24 Ultra smartphone. Here we discuss the key differences between the two devices.
Main differences between Galaxy S25 Ultra and Galaxy S24 Ultra
Design:
The Galaxy S25 Ultra comes with a flat display and gets rid of the Galaxy Note-like boxy design that the company has used for the Galaxy S Ultra models since 2022.
At the back, the Samsung Galaxy S25 Ultra has the same camera sensor design as the S24 Ultra, yet, the camera rings are thicker, and the lenses are housed in a slightly raised, metal or glass-like casing that blends seamlessly with the rear panel.
Display:
Galaxy S25 Ultra features durable titanium and new Corning Gorilla Armor 2, a first-of-its-kind material that is more durable than glass. In addition, it combines Corning’s glass-ceramic with a proprietary anti-reflective surface treatment, which helps ensure anti-reflection surface treatment and scratch resistance, as well as advanced drop protection.
Camera
The most prominent upgrade that the Galaxy S25 Ultra is getting is a 50-megapixel ultrawide snapper on the back which delivers clearer and sharpens pictures over the S24 Ultra’s 12MP Ultrawide camera. Also, the company has significantly improved nightography as well as added a new feature to capture better portraits at night with AI capabilities.
Processor
Apart from this, this year Samsung has launched only Snapdragon processor-based variants so that users in other countries do not have to compromise with low-performance chipsets. The phone has Snapdragon 8 Elite mobile platform which is specially designed for Galaxy. Plus, it comes with an improved vapor chamber for heat control.
Battery
In terms of battery, both Galaxy S Ultra series phones pack a massive 5000mAh battery with 45W fast charging. But, the latest Ultra battery efficiency is improved with the latest AP. Notable, the Galaxy S25 Ultra’s Wired charging compatible with Qi2 and AFCPD.
S Pen
The S Pen on the Samsung Galaxy S25 Ultra does not support Bluetooth. Due to this change, potential buyers will have to compromise on some important features like remote control and Air Action.
Samsung is reportedly planning major upgrades for its future Galaxy S27 series. Even though these flagship phones are still far from launch, new leaks have revealed that Samsung is working on the Galaxy S27 Pro alongside the Galaxy S27, Galaxy S27 Plus, and Galaxy S27 Ultra models.
Galaxy S27 Pro leaks
As per the GSMA database Documents, Samsung has three unannounced devices in the pipeline. The database has three model numbers: SM-S956U, SM-S957B/DS, and SM-S958U. According to this, the SM-S956U model number identifies it as the Galaxy S27+, while those for the SM-S957B/DS identify it as the Galaxy S27 Pro, and the SM-S958U lists it as the Galaxy S27 Ultra.
Additionally, the Pro variant phone is expected to resemble the Galaxy S27 Ultra in terms of specifications closely.
In terms of specifications, the Galaxy S27 Pro is expected to feature a more compact design, sporting a 6.5-inch Dynamic AMOLED 2x display. There is also talk that it will not include an S Pen.
As for the cameras, this phone could feature a 200MP primary rear camera, a 50MP ultra-wide camera with autofocus, and a 50MP telephoto camera with 3.5x optical zoom. Additionally, it includes a 12MP front camera for better selfies.
The Galaxy S27 Pro is expected to feature the Snapdragon 8 Elite Gen 6 Pro for Galaxy processor. Additionally, it may come with 12GB or more of RAM and 256GB or more of UFS 5.0 storage. The phone could house a 5,000mAh battery with 45W or faster charging.
Based on previous launch timelines, the Galaxy S27 series is expected to launch in the first quarter of 2027. Stay tuned for more facts.
Samsung has reportedly commenced Android 17-based One UI 9 testing for the Galaxy S26 series. The first-ever Android 17 build has surfaced on Samsung’s firmware server, suggesting an early debut of the next One UI version.
An alleged Android 17 firmware has been listed on CheckFirm (via TarunVats) for the Galaxy S26 Ultra. That said, Samsung kicked off its work on the One UI 9 system for the latest flagship nearly two months earlier than usual.
Based on available information, Samsung is currently testing the BZC5 build on the Galaxy S26 Ultra. Samsung will take its time to refine this new operating system for Galaxy devices and will not rush the release of the firmware.
Although testing for One UI 9 has commenced early, this does not imply that it will become available to customers any sooner. Samsung will take the necessary time to optimize this new operating system for Galaxy devices and will not rush the firmware release.
On February 25, Samsung launched the Galaxy S26 series, and these phones will be available starting March 11. A day later, the company began rolling out Beta 6 for the Galaxy S25 series, but it seems this may not be the last beta before the stable version is released. Meanwhile, the Galaxy S25 series is still receiving updates through the One UI 8.5 beta program.
Samsung One UI 8.5 beta 7
A reliable tipster, @TarunVats, spotted a new One UI 8.5 beta build for the Galaxy S25 series on testing systems. The build ending in ZZC3 indicates that Samsung is preparing the seventh beta update for the S25 phones. It’s worth noting that this build began rolling out in March, but the patch level is still February 2026.
The new build suggests that the beta program is still active even after the Galaxy S26 series launched with One UI 8.5 features and improvements. Galaxy S25 Users may have to wait a little longer for the final stable update.
The latest One UI 8.5 Beta 6 update fixed many problems and improved the phone’s performance, including Bixby, Gallery, Now Bar, Now Brief, Display settings, Modes, and Routines.
At this time, Samsung hasn’t officially confirmed how many more beta updates will arrive or when the stable One UI 8.5 version will be released for the Galaxy S25 series and older phones. However, the new beta build is a strong indication that at least one more beta update is on the way. Galaxy S25 users who are part of the beta program should keep an eye out for new updates.
