Samsung Galaxy Watch7

Falsely advertised, badly designed, fails at basic reading. The website advertising said it could monitor sleep apnia. I spent quite some time reading a range of incomplete documentation to get this working. The function simply does NOT exist on the watch. I eventually discovered some small print on the website which says. "Not all features available in all regions". This function seemed simply falsely advertised in Australia.

I assumed the same applied to it's "VO2Max" measuring, which also did not exist on my watch. But after months I discovered that when I configured the watch for the best available GPS positioning, the menu option magically appeared. After a few days it started producing numbers.

Even though the above options do not exist initially on the watch, many options do exist but cannot be used. When you click on them it says these features only work on the Watch 8. Why add them to the menu at all?!??! Options that can never work are always in the menu system, and options that should work are not in the system at all. Silly design.

But worse, virtually every night when the watch measures my sleep, there are periods in which it measures nothing. These last from between 30 minutes to 4 hours. At first I assumed that the watch was saying that I was awake in the period, but later realised that it was simply not measuring at all - according the the watch - I had no heartbeat or breathing at all then (there are separate periods when it does measure me as awake). The results then are significantly influenced by this failure. I am wearing the watch exactly as per recommendations.

The algorithm also values the proportion of time in good sleep over the absolute time in good sleep. This means that I have slept for an hour total and gotten a sleep score of 47, and yet have slept for 6 hours and have gotten a sleep score of 32 - even though my total of deep/REM sleep was much larger in the 6 hour sleep night. This is a patently simplistic algorithm which delivers little value.

The watch's configuration and options are split between the watch and the TWO apps you need to manage the watch. Much time is wasted finding options. The documentation is poor - including that it actually mislabels the names of the required App Store apps.

This watch is badly designed, badly documented, has simplistic and poor algorithms and fails to deliver most nights that I use it.

It is astonishing that a company the size of Samsung could deliver something so poor.

continual problems trying to get the advertised features of this watch to work. Only records a BP 1 in 10 tries. Fails to record sleep accuratley if at all, and fails to record sleep apnea unless you manually turn the feature on every day. Sens annoying "notifications" continuously and you can't stop them unless you turn ALL notifications off, which defeats the purpose of having the watch. battery goes flat quickly if you look at it. Customer service is useless, They tried to tell a health professional ow to take an accurate BP instead of understanding that the problem was no accuracy of the reading but not getting a reading at all. They insist on you sending "logs" from your phone every time you contact them about a problem without telling you what personal information they are accessing or what they are doing with it. Watch was just an expensive way to see the time.

Ordered products through JB online. Paid extra for it to be delivered to my home. They ignored instructions and sent goods to an out of the way parcel locker 25 km away. So in these days of soaring petrol prices have to travel to an unfamiliar place. Only thing JB are good at is bullying and incompetence.

I brought this watch for the ECG app and after purchasing found out it doesn't work with non Samsung phone's so now I'm stuck with a $280 watch that I don't need, Samsung should have to put in the ad that this watch's ECG app will not work on non Samsung mobile phones.
