When first turned on, the watch was synchronized with the smartphone; Samsung Pay has imported all cards; so that they only had to be activated for this watch. The firmware ate has arrived. After the ate, the cards of the payment service did not fly off (well, this moment is already pleasing; with Gear 3, I relinked the cards from scratch every time for the first 3 ates β more fun!). The customization of the dials is much richer than that of Tizen (but here, apparently, the matter is in the developers). First of all, having finished with synchronization, I armed myself with a "clothespin" to determine the pulse and oxygen in the blood. Compared the figures with the clock. The difference is about 1-3 units. Measured several times; testimonials are true! As for Blood Pressure and ECG, these 2 functions only work with Samsung smartphones. I have a Samsung smartphone; there are no problems here. But, frankly, in vain the company did not leave the opportunity for owners of third-party smartphones to use the full functionality; sales would be higher; competitors do not have BP! Apple's bad example is contagious. He adjusted the watch together with the tonometer β strictly according to the manual. I compared readings with a tonometer several times during the day; the difference is +/- 5 - 10 units. Quite worthy. I am hypertensive, and knowing about the increase in blood pressure is vital for me. BP and ECG measurement are the 2 features that prompted me to replace Gear3 with Watch4. About the ECG: you still get the full picture only when using a full-fledged device; but the watch will be able to indicate the presence of an arrhythmia, β and this is very important. About autonomy. I have been wearing it for a day since the last charge; slept in them. At the time of sleep, switched to the "Do Not Disturb" mode; so that the screen does not light up at night unnecessarily. Turned off WiFi and GPS. I do not always use WiFi, in GPS β there is no special need either; Watches without GPS cope with counting steps. A day later, 70% of the charge remained. I canβt say what will happen next, but so far the watchβs appetites do not seem supernatural to me (I will add a review on this topic later).
