Wear OS 4: A New Operating System for Samsung Galaxy Watches

Published

on


The most recent version of Google’s smartwatch operating system, Wear OS 4, runs on Android devices. It is the successor to Wear OS 3, a groundbreaking Samsung-Google partnership that debuted in 2021 and completely changed the Wear OS platform and Wear OS 3.5, which is presently available on a few top-tier Wear OS devices. Your app must support the system behavior modifications that came into effect in Android 12 and 13 since Wear OS 4 is based on Android 13, which is many releases older than the current Wear OS version. The most recent version of Wear OS brings a number of enhancements and a few practical new capabilities.

Wear OS 4 brings several new features & improvements

The Galaxy Watch 6 series, which was unveiled on July 26, brought this Wear OS 4 operating system’s debut. On August 11, the Watch 6 series will be the first timepiece to run One UI 5 Watch based on Wear OS 4, which will come into effect. The firm brings cutting-edge capabilities to its Galaxy Watches, but other Android watches will continue to use Wear OS 3 for a while. Backup and restore features are the most notable features that are offered. Following this, other features, such as Gmail or Google Calendar, will be included.

Better integration of smart device controls and alerts, as well as other features, is another feature of Wear OS 4. A WhatsApp app was also added to the platform earlier, rolling out to Wear OS 3. Even WhatsApp calls may be accepted from the user’s mobile device using this software. Among the platform’s apps, well-known ones like Spotify and Peloton have released updates. Samsung’s One UI 5 Watch, which builds on Wear OS 4, has additional capabilities, including SOS and fall detection, customized heart rate zones, and enhanced sleep monitoring.

Older Galaxy Watches will also get these capabilities in addition to the Galaxy Watch 6; as of early August, Samsung is on the fifth One UI 5 Watch beta, which is very close to being stable. The Google Pixel Watch 2 is expected to launch in October and may debut with Wear OS 4.

Samsung Galaxy Watch 7 & Galaxy Watch FE Are Close To Take The Floor

Published

Samsung is actively looking forward to expanding its wearable smartwatch family by adding one more member to the line called the Galaxy Watch 7, which is expected to arrive with the Exynos W1000 3nm. On the other hand, the existence of the Galaxy Watch FE is also confirmed. 

The next-generation Galaxy Watch 7 is supposed to be introduced at the Galaxy Unpacked event in July, consisting of three variants, including an “Ultra” model that could be the first smartwatch with a 3nm chipset. However, another affordable model is also rumored to be in the line called the Galaxy Watch FE

Initially, the rumors teased the fan community that the forthcoming Galaxy Watch 7 series’ three model could arrive with a 3nm Exynoss W940 chipset. If the new reports are to be believed, the upcoming watches will still be the first Samsung smartwatches with a 3nm chip, but the chip might be named the Exynos W1000 by contrast. 

The predecessor series Galaxy Watch 6 lineup arrived with the 5nm Exynos W930, and according to the new reports, the latest Exynos W1000 should bring 12% more enhancement in performance as well as energy efficiency. If the reports come true, then Samsung will introduce the Galaxy Watch FE alongside the Galaxy Watch 7. 

The Galaxy Watch FE is expected to be more affordable, similar to the recently launched Fan Edition phones and tablets such as the Galaxy Tab S9 FE, Galaxy Tab S9 FE+, Galaxy S23 FE, and Galaxy Buds FE. The reports from Android Headlines are revealing the two popped-up firmware models on the Samsung servers: the SM-R866 version, which was actually already looked at previously as an LTE variant, and the SM-R861 version with the R861XXU0AXE5/R8610XM0AXE5 firmware, which is expected to be a Wi-Fi or Bluetooth variant. 

It seems that the forthcoming Galaxy Watch FE may feature a lot of similar specs as the Galaxy Watch 4; for instance, a 1.2- or 1.4-inch AMOLED display, an Exynos Wg20 SoC, and more.

Samsung Patents Method to Convert Galaxy Watch PPG Data into ECGs with GenAI

Published

Samsung is actively working on expanding the Galaxy Watch’s functionalities for users’ convenience. The company has filed a US patent for continuous atrial fibrillation detection through PPG ECG signal translation. 

Many smartwatches available on the market perform atrial fibrillation (AFib) spot checks using an ECG sensor, but unfortunately, continuous AFib data is impossible without a medical monitor. A week ago, Samsung patented a plan to convert that for the forthcoming Galaxy Watch 7 by employing a generative AI model. 

Initially spotted by Wareable, the US patent “System and method for continuous atrial fibrillation detection via PPG to ECG signal translation” would “translate PPG signals to corresponding ECG waveforms.” 

Samsung got FDA consent for the passive detection of irregular heart rhythms. Samsung, such as Fitbit, Apple, and Withings, can use their watches to monitor irregular heart rhythms. Although this is not a diagnosis tool, It is only capable of suggesting a potential issue and requires confirmation with a proper ECG reading. 

Samsung’s patented PPG-to-ECG mechanism would offer more definitive data at all times, making it more possible to catch the lead-up to serious heart conditions such as arrhythmia and heart failure. The patent describes that “conventional models” can only count on “long-term relationships” between PPG heart rhythm data and possible ECG results. Along with its GenAI models, Samsung assures that it will create a “first-order Markov relationship” between them for better accuracy. 

Samsung’s patent confesses that by using generative AI, “fake information may be introduced, which affects an AFib detection result.” The giant decided to solve this by “incorporating prior knowledge in terms of probabilistic graphical models” so that it is “robust to noise,” also known as irrelevant or misleading details. 

The generative AI plan of Samsung might make heart health data available to Google since it typically relies on Gemini AI.

Samsung Galaxy Watches Are Yet To Become More Premium As Promised

Published

By


The Korean brand ‘Samsung’ introduces smartwatches along with the software gap between promise and premium! Now, deep down, it is gearing up to expand its smart wearable family by introducing a brand new Galaxy Smartwatch lineup within the next few months. 

Galaxy smartwatch enthusiasts, the giants are cooking something new for you all, as Samsung is expected to release a new Galaxy Watch lineup or at least one in the upcoming weeks. However, a premium smartwatch model might not be the answer to each query that’s holding Galaxy Watches back. 

It’s possible that a premium smartwatch with a more polished design could be a blessing or a curse for the Korean giants. Samsung Galaxy Watches, such as non-classic ones, can look like playthings, whereas the software also doesn’t give an experience like a high-end One UI, which it should. 

One UI Watch performance appears unexciting, and the UI can sometimes falter or even lag extremely, especially after reconnecting to a mobile device. Even after spending a lot, in the end, somehow you realize that almost every UI element and widget often feels and doesn’t look ready to use or release. Most of the things appear to be in the early access phase. In many ways, it’s reminiscent of the old Android phone experience. 

Now it is expected that Samsung’s forthcoming premium Galaxy Watch could solve the external design issue and make smartwatches a bit more appealing and less playful. Also, a more premium smartwatch paired with not-so-premium software will likely accentuate the undercooked One UI/Wear OS experience. 

Somewhere, premium Samsung Galaxy smartwatches have software issues such as limited applications, watch faces, and a clumsy UI holding back Galaxy watches. A premium design would only be enough until the brand improved the software experience to feel as smooth and integrated as their smartphones. 

Apart from this, the Galaxy Watch 7series is next in line, which should debut at the Galaxy Unpacked event in July. It is also expected that Samsung will release a new rectangular-shaped smartwatch by the end of this year.
