Thank goodness Google and Samsung both came to their senses and merged with wear OSes. Samsung has always made higher quality watches, but their little walled garden OS simply wasn't practical. But now I have my Android apps on my Samsung watch, and it's all good. The watch is very lightweight and sleek; the band is maybe a little on the thick sign, costing it a few fashion points. The battery life is much improved over previous smartwatches (caveat: except, multiple timers run back to back will drain the battery in a hurry). I suppose the best thing I can say about it is, I forget it's there. It's quiet, comfortable and unobtrusive, until it needs to tell me something.

Wow. So, okay, I really don't know where to start. I guess with the cons. I previously had the Activa 2. The 4 is not only visibly bigger, but feels a little bulkier and not as sleek as the 2. I hated the band on the 4 as well, and I already changed it out. It sticks out farther, and it would catch on things. I am a nurse, so it catches on equipment at times. That's it, lol. Everything else is better. Better battery life, the colors on the screen are visibly more vibrant and intense, and the app functions work better somehow. It pairs better with my S21 too. I can use it farther away, and I can use the watch phone farther away from the phone as well. The biometric functions are so much better, that there is no comparison. . I was weary about purchasing it, but, it was worth every penny. Great job Samsung!!!

This is my first smartwatch. I read MANY ratings and reviews before deciding on the Samsung Watch4. I have a Samsung Galaxy S7 phone which meets the requirements for full functionality. *The phone requirements are clearly spelled out on Samsung's webpage. If you do not have a phone meeting these requirement then all features will not be available. Set up was easy. The watch face is easy to read and navigate. It is comfortable to wear and fits nicely on my small wrist. Samsung Health App is straight-forward as are Wear App and Samsung Health Monitor App. Battery life has been about 2 days using all features. Longer life could be achieved by turning off sleep and continuous heart rate functions. Step counting seems pretty accurate when compared with two pedometer apps. It does not count steps when riding in the car as do MANY other apps and fitness bands. Activity tracking also seems on target. I can't comment on the calorie calculation, I take this information with a grain of salt- this is a bone of contention with all fitness trackers. Most devices over-estimate the calorie burn. This has to do with with the formula the devices use (basal metabolic rate vs resting metabolic rate) and that they are worn on the wrist. I had a Body Media band many years ago- worn on the upper arm, it also over-estimated but was closer than today's devices. Their company was bought out by Jawbone who sadly did not pursue the technology. I was easily able to obtain EKG, Heart rate and O2 saturation. Also able to check email and text messages without difficulty. Sleep monitoring took a bit of trial and error. The first night obtained the information. The next day I changed some settings: Heart rate changed to every 10 minutes and turned off notifications for sleep. This led to the device no longer tracking sleep despite wearing the watch in the proper location. The manual, website and app were not helpful in figuring this out. When I put the heart rate back to continuous and turned on sleep notifications (in addition to the settings as instructed in the app and manual) it has tracked accurately. Overall: Very happy with the Samsung Watch 4!

I love this watch! I have the 44mm. I also had the 40mm for awhile until I switched to the bigger model. The battery life is better on the 44mm and the screen is better but only because it's bigger. That's the only two differences between the two. The Watch 4 is fast and good looking. Speaker on it is great for a watch. I mean everything works awesome. There really is nothing I dislike about this watch. Probably the best smart watch I've ever owned. I highly recommend this watch to any Android user. Do note that the ECG and Blood pressure monitor will only work if you have a Samsung phone. The Blood pressure monitor only works in certain countries so depending on where you live if you don't have a Samsung phone the only thing you're really missing out on is the ECG feature. Calls sound great on the watch. Messages on the watch work perfect with Google Messages and GBoard installed. Still no Google Assistant at this time so only the mostly useless Bixby is available. The screen is plenty bright for use in bright sun. I'll say it again; this is THE ANDROID WATCH TO BUY! You won't be disappointed. One more thing, battery life. The battery will last you through the day no problem on both models, smaller and bigger but not much more than a day. Maybe 2 days without AOD on. And the new Wear OS is great. Also, battery life will probably seem bad the first day you use it but give it a few days and somehow some way the battery life improves quite a bit. I give this watch 5 stars and absolutely recommend it!

The only smartwatch I've ever had was a fitbit charge 2 so I don't really have anything to compare it to, so keep that in mind. I'm a pretty sedentary and anxious human being so I got this to keep myself accountable for going on walks, meditating, and generally getting my act together. So far it's doing what I want it to. I'm going to say the SpO2 sensor is super janky, and can't decide whether I'm perfectly healthy or on the verge of brain damage from hypoxia half the time. I have no symptoms, and my readings on a regular pulse oximeter and at the doctor are consistently normal so I'm not concerned about this. I love that it auto detects my walks after a while because I always seem to forget to tell it I'm going. It tells me how long it took me to go a mile and how many steps I took and the breakdown after the walk is over is nice. The ECG feature is reassuring as well, as I can share that information with my doctor easily with the interface given. I don't understand the body composition feature so I'll maybe update this review when I talk to my doctor about it in a couple months. I wouldn't use it if you have body dysmorphia though. You can take that tab off both the phone and the watch in the settings so you don't have to think about it if you're concerned. You will need a samsung device to use ECG , SpO2, and a couple other things I can't recall at the moment, so that's a bit frustrating for those who don't have samsung everything. Every feature is very enjoyable, snappy, and pretty much everything I wanted in a smartwatch. I'm pleased with it, am moving more, and when used in conjunction with my other stress control and fitness apps I'm starting to be able to see quantifiable results from all the effort I've been putting in. I can control my music with it, send texts, make calls. My life is easier, my exercise is more fun, and I'm getting to be a lot happier with its help. The battery life sucks, but it's probably good to take it off for an hour or so a day anyway as the band is comfortable but can start to rub wrong. All in all, I'm very satisfied with it. It suits my needs better than I expected. It no longer feels like a frivolous purchase. I didn't absolutely need it, but I'm very glad to have it.

So, to be honest I read every single review about this smart watch. The biggest con that I was hung up on was the battery life. Instead of listening to everyone else I decided to take the plunge. I am glad I did! Listen, every day was charge our phones so what's the big deal that the watch only lasts a day as well? Unless you got a dud then that's an issue. I recommend this watch 100%. It does everything I want and more

I ordered the Galaxy Watch 4 directly from Samsung. I took advantage of the trade-in program on my Active 2. The Watch 4 is sleeker and more premium than the Active 2. The limited number of current watch faces being it's only drawback. The main reason for my review is to counter the review stating the touch bezel isn't touch sensitive. Nonsense! In fact, it is more touch sensitive and smoother operating than my Active 2.

Ive had many smartwatches. Moto 360, the bulky LG Sport, Fossil Gen 4 and Fossil Gen 5 (that I lost). I loved the Fossil watches because they are high quality watches using WearOS. Never liked Samsung because of Tizen. So when I lost my Fossil Gen 5, I naturally was going to upgrade to the Fossil Gen 6. I did do some other research too and the more I researched, the more I started to like the Samsung Galaxy Watch 4. I don't like bulky watches and the Watch 4 was more slender than the Classic. Reading these Amazon reviews, I was almost scared away. Anything from Google Pay not supported to the touch bezel doesn't work at all. Let me just say, not sure if these reviews were early updates or what but Google Pay works just fine and the touch bezel works just fine (although I scroll with my finger anyways). The touch bezel is good for turning volumes up and down and it works perfectly whenever I use it. Another contributing factor to choosing Galaxy Watch 4 over Fossil Gen 6 is the Fossil wasn't releasing with WearOS 3.0. I believe at the time of me typing this review, the Galaxy Watch 4 is the only released device with WearOS 3.0 and it is a major improvement on previous WearOS versions. I'm not a health nut but the integration with Samsung Health is amazing. I do like to track my steps and sleep and this watch is awesome for that. For sleep, all I do is turn bedtime mode on and go to sleep. The watch does the rest. Monitors blood oxygen and how well you slept. Not sure how accurate it truly is but I do like knowing about how long I've slept. As far as battery life, it lasts at least all day long. Usually longer. I use it moderately at work checking notifications, replying to messages and controlling my music and when I get home from working a 8-10 hour day, my watch is around 40%-30% typically. I put it on the charger before bed, put it on at 100% at bedtime and wake up to about 85% battery for the day. DO NOT LET OTHER REVIEWS DISCOURAGE YOU! I challenge you to do your own research. Watch YouTube videos or even go to a local phone store and look/feel the watch. It's definitely the best watch I've owned to date. If I had to give downsides, it would have to do with Samsungs integration into WearOS 3.0. The Bixby button is NOT reprogrammable to Google Assistant but can be disabled (not remapped). However, from videos I've watched, the Bixby assistant is useful on the watch as it can turn on and off settings by asking it. The other complaint is not being able to reprogram the Samsung Pay button. If you press and hold the bottom button, it opens Samsung Pay by default. Which is annoying if you want to use Google Pay. However, once you properly install and set up Google Pay (and make it default payment method), you don't need to open Google Pay to pay anywhere. Just tap your watch. But if you want to use a different card, you'd have to go into your apps and open Google Pay or assign it to open with a double tap of the top button (that action can be programmed to anything.). With the Galaxy Watch 4 still fairly new, I'm hoping Samsung continues to provide updates from community feedback. And by this time, I've hope you read my entire review and are placing your order now. Stop second guessing yourself, this watch in my opinion is the best out there right now.
