By the end of 2024, leading mobile phone brands had largely unveiled their flagship devices. As 2025 approaches, the smartphone market gears up for a fresh wave of upgrades. Among them, Samsung's Galaxy S25 series, hailed as the king of Android phones, naturally garners significant attention. Now, according to the latest scoop, a reliable source has further detailed the high-end model, the Samsung Galaxy S25 Ultra.

Firstly, Apple equipped its iPhone 14 Pro with a crash detection sensor capable of detecting front, side, rear-end, and rollover collisions. Upon detecting a crash, it automatically dials emergency services. Similarly, the Apple Watch S8, Apple Watch Ultra, and subsequent models feature this lifesaving technology, resulting in numerous rescue missions following car accidents.

As Apple's long-standing rival, Samsung will also integrate a crash detection sensor into the Galaxy S25 Ultra, offering emergency services and rescue assistance. Recent news hints that Samsung's upcoming Galaxy S25 series might include this feature. While Pixel phones have had this feature for some time, it remains relatively rare among other Android flagship models. Samsung has been striving to incorporate this feature into its flagship lineup but has yet to make significant progress.

According to foreign media reports, leaked documents of the Galaxy S25 Ultra reveal that the device will indeed come with a crash sensor. Notably, the same sensor was already present in the Galaxy S24 series and Galaxy Z Fold 5.

However, it's puzzling that despite several Samsung phones being equipped with sensors capable of recognizing potential car accidents, the crash detection feature doesn't seem to be officially enabled on any device in any region. Currently, neither official documents nor user reports mention this feature, nor is it visible in system settings. This suggests that Samsung may still be refining and debugging the feature.

The "crash detection wakeup" sensor in these Samsung devices is a composite sensor that processes and integrates data from underlying physical sensors. In the One UI 5.1.1 version, there was a hidden system application named "MoccaMobile" containing code to start and stop the crash sensor. However, Samsung has yet to activate any user interface related to the crash detection feature.

Whether Samsung will officially launch the crash detection feature on the Galaxy S25 series remains to be seen.

Additionally, a source has disclosed the camera specifications of the S25 Ultra:

Front Camera: Samsung S5K3LU, 12 million pixels, equipped with Dual Pixel technology, delivering clearer selfie videos and superior color contrast.

Notably, the Galaxy S25 Ultra will also support satellite communication, marking Samsung's first domestic flagship phone with this capability. However, it's unclear whether the domestic version of the Galaxy S25 Ultra will utilize the Beidou or Tiantong satellite system. We'll have to wait for the launch event for confirmation.

Regarding design, this leak didn't provide specific details. Based on previous reports, the Galaxy S25 Ultra might continue the design aesthetic of its predecessor, maintaining a square shape.

The Samsung Galaxy S25 Ultra boasts the industry's narrowest four equal-sided design, with a bezel width of less than 1.38mm, narrower than the iPhone 16 Pro Max and Xiaomi 15, ensuring an enhanced visual experience.

In terms of other hardware configurations, the Galaxy S25 Ultra is rumored to come with a 6.9-inch screen featuring 2K resolution, a 120Hz refresh rate, and a peak brightness of 3000nits. It's expected to be powered by a customized Qualcomm Snapdragon 8 Gen 3 SoC, offering up to 16GB of RAM and 1TB of storage, alongside a 5000mAh battery supporting 45W wired and 25W wireless fast charging.

Notably, the Samsung S25 Ultra will be equipped with a full-fledged Snapdragon 8 Gen 3, featuring an unprecedented CPU clock speed of 4.47GHz, surpassing the currently available 4.32GHz version.

The full-fledged Snapdragon 8 Gen 3 continues to utilize TSMC's second-generation 3nm process. The CPU comprises 2 Oryon big cores clocked at 4.47GHz and 6 Oryon big cores at 3.53GHz, delivering robust computing capabilities.

Furthermore, the S25 Ultra will be upgraded to 16GB of RAM, making it one of Samsung's flagship models with the largest RAM in its history. The phone is set for an official release in January, and based on the Ultra's positioning, the top-tier version of the S25 Ultra is anticipated to cost over 10,000 yuan.

Finally, it's reported that Samsung is expected to host an Unpacked event this month to officially unveil the new Galaxy S25 series. More details will be announced then.

According to leaks, Samsung's Galaxy S25 series launch event is scheduled for January 22nd, introducing four products: the regular iterations of the Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra, along with a Galaxy S25 Slim model emphasizing an ultra-lightweight and thin design.
