A few things to tweak before it's usable but otherwise a great product
Overall, this is a watch that gets a thumbs-up from me. I'm not overly interested in all of the fitness tracking features. I'm unfit, I already know it and I have a job that keeps me busy 8 days a week leaving me no time whatsoever for working out. What I do use is the sleep monitoring function with blood oxygen level monitoring. This works a lot better than other smartwatches I've owned. The back of the Galaxy Watch 4 is smooth, so it fits snugly against the wrist without leaving an imprint and is able to able to take accurate blood oxygen level readings. Plenty of people have left bad reviews of this watch because of its poor battery life. On the whole I'm getting 3 days out of a full charge with moderate use, "always on" switched off and "Bedtime" mode scheduled to kick in automatically at night. Can't complain about that. The display is crisp with great contrast. The brightness adjustment depending on ambient lighting levels is effective and much appreciated. The touch screen is mostly responsive, only a few cases of lag or missed touches. Google Pay works after a bit of tweaking. The default payment app will always be Samsung Pay, but at least it is now possible to install and use GPay here in the UK. There are some localities where this is not possible and where you're stuck with Samsung Pay. For the things that need tweaking... Firstly, I put an after market strap on the watch. I don't get on with resin straps at all. They always make me come out in a rash and then crack and break on me, and I don't want to lose the watch because of that. A leather strap went on straight away. Secondly, the watch face. Maybe it's just me being a luddite but I do like a watch face that looks like a watch, not like something out of an animé cartoon that I grew out of about 50 years ago. The out-of-the-box setup is not what I would want to use, but it is not hard to set the watch up to work how you want it.

Best Rival to the Apple watch
I have never used an Apple Watch but have seen a lot of videos on YouTube. Enough to know that the Watch4 is just as good. I have had Fitbit fitness trackers as well as Samsung's Active and Active 2 44mm. I had originally purchased directly from Samsung the smaller 40mm Watch4 and found the battery to be pants. I returned it to get a replacement in the hope that the next one was going to be better but they were out of stock and gave me my money back. Purchased the bigger 44mm one direct from Amazon and it came with prime 2 days later. Well done Amazon for a speedy delivery. WOW just WOW. Firstly the battery is so much better. I can get a day out of it now and that includes sleep tracking. As for steps this does not count as many as a Fitbit and makes some adjustments for the fact that you wear this on your wrist. Wrist-based step counters need to adjust so that it doesn't count every single wrist movement as a step even when you don't step. I love that the screen and sensors have been improved/upgraded. There is now a BIA (bioelectrical impedance analysis sensor) that measures body compositions from body water to body fat to skeletal muscle. I don't get too serious with the numbers as long as I can move from the red into the green is fine with me. I love that I can now use more apps with this device such as shazam. This is claimed to be operated as wear OS powered by Samsung. This means most things such as step, sleep and exercise tracking is done through Samsung. If you want it to be more like wear OS you can install the relevant Google apps such as Google fit. Personally coming from and Active 2 I love that this is a hybrid of the best of Tizen OS with the best of wear OS. Best smartwatch ever. Best Apple Watch rival yet. DO NOT GET IF YOU HAVE A iPHONE AS THIS WILL NOT WORK WITH AN iPHONE. Overall WOW.

Great watch but battery life poor
Overall this is a nice watch with some great features. I haven't been a fan of watches in general as I often find them uncomfortable and just annoying to have on my wrist. This however is extremely comfortable and I don't really notice it on my wrist. I also love the design. Nice good quality screen which I find just the right size. The watch is also fairly easy to navigate and simple to use. It also has some great features. I love that you can take and receive phone calls with it which is handy for me as I live in a 3 story house meaning that sometimes my phone is on the top floor and Im say in the kitchen cooking. I can leave my phone upstairs but can still take or receive a call or message using the watch. Its also handy that I can use it to make or receive a call when Im driving using the bixby feature. I can just press and hold the top right button and ask it to call a contact and it will call them. The pay app (I use Samsung pay) is also excellent and convenient. Spotify is also a useful app to use when im in the gym. It saves me having to keep getting my phone out if I want to switch songs etc. The only problem is that firstly the app is at times a little unreliable as it sometimes seems to lose connection with my bluetooth ear phones. I've also noticed exessive battery drain when using the app. This brings me on to the main negative of this watch which is the battery life. Even when employing all the battery saving techniques such as wifi and location off, AOD off, heart rate measuring off and a dull low power consuming watch face mongst others, I'm still only just about getting 2 days battery life with minimal use which seems very poor. It does however fully charge from 0% to 100% in about 1hr and 40 mins using my samsung fast charger which s reasonably fast charging. I have also noticed issues with the sleep measuring. It was working ok for a few days but then for no apparent reason it has stopped giving me a sleep score. I dont know if this is an issue with the watch or the health app. I have a Samsung galaxy s21 ultra which is one of the reasons I wanted a Samsung watch over other brands as I believe some features work better with a Samsung phone and others possibly dont work at all. Overall it's a nice watch and I'm happy with it. It's just a shame about the battery life. I would that this could be improved with updates.
