    • Solid android-compatible smart watch
Color: Pink Gold Size: 40mm Style: Bluetooth
I decided to upgrade from a fitness band/watch garmin device to this smart watch. I know there are about 3 subsequent versions of this, but mine still works very well after over 2 years. Positives: - I like being able to see at least part of incoming text messages so I can decide if I need to pull out my phone to read them on a larger screen. - The do-not-disturb feature is very helpful in muting text messages when I can't afford interruptions - I do like the variety of fitness tracking options, as well as health and sleep - The battery life is still pretty good even after several years Negatives/downsides: - I still find it hard to cancel notifications rather than just snooze them (the swipe to clear feature doesn't always work--could be the screen protector I use) - It took me a while to realize that having the watch on DND means that calls won't go through on my phone even if the volume is on for that device - Battery does have to be charged each night, which limits the usability for sleep tracking (unless I charge it earlier and then can't track activity/steps) Overall still a quality device and I haven't been compelled to upgrade yet. ... show more

    • Best Smartwatch Available?
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. ... show more

I've only had this watch for about a day now. In some cases it meets my expectations and in others it succeeds. There are other things about it that I have mixed feelings about, but I'm sure that as I continue to use it and figure it out those areas of concern will iron themselves out. I've owned several smartwatches in the past including a Ticwatch 2 and a Samsung Fit2. Both I liked well enough, but I found they lacked many health features. I have a Samsung phone and since my Fit2 worked more seamlessly with it than my Ticwatch 2, I decided to keep with the Samsung brand. I'd recently updated my phone from a S8+ to an Ultra S22 Plus. While my Fit2 still worked very well with the new phone, I still had to manually enter sleep and there was no way to measure my blood oxygen. During Amazon's Prime Day, they had a great deal on the Galaxy Watch 4, so I decided to take the plunge. I'll get the issues I have mixed feelings about out of the way first. When I got the watch yesterday, I got it fully charged and paired it with my phone easily enough. Later on while I was playing around with selecting watch faces and figuring out the AR emoji watch face, the watch somehow disconnected from my phone. I was able to get it to reconnect by turning the Bluetooth off and on through the watch. It did the same thing later on in the day while I was just sitting and watching TV and not even touching the watch. Both times the issue occurred, my phone was less than a couple of feet away from me. So I know it wasn't because my phone was too far away. Hopefully this won't be a reoccurring problem. Another issue I seem to be having is notifications that I want to show up on the watch aren't showing up. I've already gone through the notifications settings on both my phone and the watch and set things up the way I want them, but the notifications are still not showing up on the watch. I'll have to play around with it some more. Now, on to the good stuff! It seems to do a great job of reading heart rate, sleep, steps, basic stuff for a smartwatch. I really didn't know what the body composition or the ECG was all about when I ordered it, but I thought, "Hey! This could be cool. Why not?" And it is interesting and gives some valuable insight. However, in order for it to take many measurements accurately I have to move the watch about a finger width above my wrist bone on my arm. I'm fine with that. A lot of other smartwatches that take the same kind of readings work the same way. It would be nice if the smartwatch industry could find a way to take those measurements without the wearer having to move the watch around, but until then those who want to keep a close eye on their health will have to choose watch bands for their smartwatches that can be easily adjusted. Another thing that I didn't really know anything about was the stress measurement feature. I have absolutely no idea if it measures stress accurately, and, frankly, I really don't care. However, I do like that after it takes the reading it offers a built in breathing exercise. I may not know anything at all about how the watch measures stress, but I do know that breathing exercises have been known to help relieve stress and anxiety. They also help people focus and even get to sleep faster. So, having something like that built into the watch is pretty cool! Another thing that I found really cool are all the different music features. Not only can you control music apps on your phone through the watch, but it has a built in mic and a small speaker. So, if you're away from your phone or don't want to take it out and wanted to have a voice recorder handy to make notes or something later, you have access to one right on your wrist. You can also directly download music from your phone to the Galaxy Watch 4 and can listen to music through either Bluetooth connected earbuds or directly through the little built in speaker. As with all new gadgets, it takes some time to get used to them and figure out which apps you really need and which ones you don't, and exactly how you're going to use it. I imagine, over time, the watch and I will get used to each other. ... show more
