For best results in detecting and recording snoring, place your smartphone on a stable surface near your head with the bottom of the smartphone pointed to your head. I will give Samsung another chance this Friday with purchasing Classic Gen 4 (46 mm), but I'm extremely disappointed by the nightmare experience Gen 1 has been giving me. If you experience redness, itchiness, or other irritation, remove your Galaxy Watch4 and consult a medical provider prior to continued use. Such reaction may result due to allergies, wearing for prolonged periods, usage habits such as wearing it too tight, or exposure to sweat or other irritants.

But sometimes, when you make many changes at once, there's more chances for individual changes to fall short. The battery life could be more consistent, and Wear OS is missing some key features at launch. I'm also hesitant to celebrate the benefits of wrist-based body composition analysis for the number of people the feature might be unsafe for. Device activation is only available after connecting to a smartphone that supports Google Mobile Services(GMS). Please refer to your device manufacturer to find out whether your smartphone supports Google Mobile Services(GMS). The only major gripe I’ve had with Samsung’s wearables in recent years is that there hasn’t been much progression between iterations. As with lots of tech nowadays, each model has improved on the last but not by so much that I’d recommend rushing out to buy the new one.

Another recovery tool, the Galaxy Watch 4’s stress app shows your stress levels. I stayed in the green, which means not too stressed, but the smartwatch still gave me the option to launch a breathing session. The Fitbit Sense takes a more convincing approach to stress monitoring and management, though it’s encouraging to see Samsung’s watch catching up.

The Samsung Galaxy Watch 4 Classic’s battery life is, without a shadow of a doubt, its worst feature. While the standard model lasts about two days between charges, based on our review time, in our testing we’d estimate that the Classic lasts less than a single day before running out of charge. In addition to Samsung’s core apps for weather, reminders and alarms, you’ll find a couple of standout new entries here, including Google Maps and, importantly, Google’s Play Store. The latter opens up a whole range of possibilities compared to what’s possible with any recent Samsung smartwatch, with apps such as Shazam, Couch to 5K, Nike Run Club, Calm, Komoot and Telegram all available, in addition to Google essentials such as Google Fit, Google Pay and Google Keep. Unlike on most other watches, where you can adjust the angle of the strap relative to the body, on the Watch 4 Classic, the straps can only protrude perpendicularly from the sides of the body, which results in a sizable gap between the strap and your wrist on either side of the body; you can see this issue in the image of the standard Watch 4 below – and we'd consider our wrists to be pretty average-sized. For optimal reading accuracy, your Galaxy Watch4 Classic needs to be snugly fastened to your wrist. When you are not conducting readings, you may loosen the band to provide breathing room. On balance, your watch’s band should not be fastened too tight or loose: make sure that it feels comfortable around your wrist. Otherwise, little has changed physically. The smartwatch is unmistakably the successor to the Galaxy Watch 3 and, aside from its low-profile buttons, which look more akin to those on the Galaxy Watch Active, you’d struggle to differentiate the two at a glance.

Measured blood pressure history can be reviewed within the Samsung Health Monitor app on a paired smartphone. You might assume that because the Samsung Galaxy Watch 4 Classic is bigger it also has a bigger screen, but you’d assume wrong. As noted, that extra size seems to be down to the bezel and general design, while the screen itself is actually the same size on both models. Supported watches: Galaxy Watch4 Classic, Galaxy Watch3, Galaxy Watch Active2 and later released Galaxy Watch and Active models (excluding Galaxy Fit)It’s bigger and heavier primarily because it has a rotatable bezel around the edge of the screen. This is handy for navigating the watch, and gives it a more classy design, where the standard Galaxy Watch 4 is more sporty and uses a virtual bezel for navigation.

We were sent a Bluetooth-only 46mm Watch 4 Classic for review, but whichever variant you choose, the Galaxy Watch 4 will come with the same Exynos W920 chip inside.
