Samsung Galaxy S26 Ultra teardown reveals the clever camera tech Unpacked skipped

Samsung Galaxy S26 Ultra Teardown Reveals Subtle but Significant Hardware Upgrades

Samsung’s latest flagship, the Galaxy S26 Ultra, might not look drastically different from its predecessor, but a detailed teardown by tech YouTuber Zack Nelson reveals that the company has quietly made several meaningful hardware changes. While Samsung spent much of its Unpacked event hyping up AI features, the real story lies beneath the surface—especially in the camera, cooling system, and internal engineering.

Camera Gets a Major Boost with New Light-Capture Design

One of the standout upgrades is in the camera system. The S26 Ultra retains the 50MP 5x periscope telephoto lens from last year, but Samsung has completely reworked its internal layout using a new design called ALOP (All Lenses On Prism). In traditional periscope cameras, a prism blocks some incoming light before it reaches the sensor. Samsung’s new approach places the lenses directly on the prism, allowing significantly more light to pass through.

Combined with a brighter f/2.9 aperture (up from f/3.4), this change increases light intake by approximately 37%. The camera module is also about 22% shorter, allowing for better optics in a slimmer frame. This should translate to noticeably improved low-light performance and sharper zoom shots, especially in challenging lighting conditions.

Cooling System Gets a 15% Boost for Better Performance

Another critical upgrade is the cooling system. Samsung has increased the size of the vapor chamber by roughly 15%, giving the phone more surface area to dissipate heat. This is a big deal for power users who game, edit videos, or run AI-heavy tasks, as modern flagship chips can get extremely hot under sustained load.

The larger vapor chamber helps maintain performance during long gaming sessions or while recording high-resolution video, preventing thermal throttling and keeping the phone running smoothly. It’s a subtle but crucial improvement that enhances the overall user experience.

S Pen Slot Gets Smarter Protection

Samsung has also made a clever change to the S Pen housing. The company has separated the stylus slot from the phone’s internal components with a sealed design. This means if liquid gets into the S Pen slot, it’s less likely to reach and damage the phone’s internals. However, the slot’s dimensions have been slightly altered, so styluses from previous models won’t fit properly in the new S26 Ultra.

Hidden Engineering Tweaks and a Missing Feature

The teardown also uncovered some unique engineering choices. Inside the speaker modules, Samsung added tiny balls to reduce the “tinny” sound often associated with small smartphone speakers, improving audio quality.

Interestingly, the anti-glare coating that was a highlight of the S25 Ultra appears to be missing on the S26 Ultra. Nelson speculates this may be due to the new Privacy Display feature, which narrows viewing angles to keep content private. Samsung hasn’t confirmed this, but it’s a trade-off some users might notice.

Repairability Remains Strong

For those who like to tinker or repair their own devices, the S26 Ultra is still relatively user-friendly. The back panel can be removed with heat, and the battery is fairly easy to replace. This is good news for repair shops and DIY enthusiasts.

Android Central’s Take: Small Upgrades, Big Impact

Samsung didn’t make any dramatic design changes this year, which might disappoint those hoping for a fresh look. However, the upgrades—like a brighter periscope camera, better cooling, and smarter protection—make the phone more reliable and capable for everyday use. The teardown shows that flagship phones are now about incremental but meaningful improvements rather than flashy overhauls. Whether that’s exciting or underwhelming depends on your perspective, but if these changes mean better photos and less overheating, most users will be happy with the trade-off.
