Mass problems with the pressure sensor and Samsung's complete indifference to this situation, the problem is really massive, and you can read a lot about it here.
The operating system itself is extremely raw and meager, "smart watches with an operating system" ! will not be able to show you the number of steps for yesterday ! , you can see the approximate value on the chart for the week, and if today is 00.05 and Monday, then sorry, the chart for the week has already been ated and is completely empty, and see the values in your phone.
There are widgets in the clock, among the widgets there is a pulse measurement, as soon as you scroll to the widget, the measurement starts, but if the clock did not have time to measure, and the screen timeout is over, then they simply turn off, and when turned on, they start measuring the pulse again, and you need not give an hour to sleep while they measure - a fierce game.
Samsung Pay takes a long time to start, if after you hold down the start button you lower your hand, the clock will turn off and the launch will not occur, you need to wait a second before lowering your hand, after which they will no longer "turn off". In general, paying by the clock is not as convenient as it seems, the application starts up for a long time, you have to press the screen to start the payment, and the terminals are installed disgustingly in places and you, like a fool, try to put the clock there and nothing works. (hello McDonald's).
Working with notifications is also poorly implemented, if you receive messages in a telegram chat in a row, opening one, you go to the "dialogue", where there is the last and previous messages, but if another one came at the time of reading them, then you will not see it.
Watches only recently learned to notify about calls to WhatsApp and telegrams, as well as to show sent pictures, that is, the owners of watches at the start of sales did not have such features, and let me remind you, according to the assurances of corrupt bloggers, "this is a smart watch, with an operating system, and not a fitness bracelet."
