Review on 💪 Experience Advanced Health and Fitness Tracking with Samsung Galaxy Watch 4 Classic 42mm Smartwatch - GPS, ECG Monitor, Sleep Cycles, Fall Detection, and Bluetooth - Black US Version by Anand Lal ᠌

1. A disgusting complete strap, sticks into your hand, even if it is not tightened, for example, when you sleep in your watch. His hand sweats underneath. By the way, under the clock, too, the hand sweats, it's unpleasant. 2. No e-sim, it would be very handy, especially when it comes to remote connection to a smartphone. 3. Wear os - yes, the system is smart, the interface is responsive, and so on, but Tizen worked more stable, was run in, and autonomy was much better, work from a single charge . this is a separate issue. And there are lags and glitches, it especially infuriates when the interface stops responding to the bezel, but as soon as you turn off and on the screen, everything starts working. 4. Autonomy, battery, call it what you want. In my use case, after the last ate (10/28/21) it got better, but still not enough. The operating time from one and a half days, up to 2 days and 5 hours, still falls short of the previous records on Tizen, this is a fail. 5. There is a question about the accuracy of the pulse oximeter. Saturation often does not exceed 98%, although I do not smoke, do not get sick, etc. And medical devices at the doctor's appointment consistently show 99-100%. And drawdowns up to 85%, well, this is ridiculous, I should be suffocating with such indicators. Conclusion one, the sensor is inaccurate. 6. Long charge. The watch takes about 2 hours to charge, when charging, they sometimes turn on the screen (GLUCK), and the charging time increases, although it should be 1 hour 40 minutes. 7. Strong heating, the temperature was very unpleasant when ating, I also observe a high temperature when charging, I don’t think it’s good, it seems to me that they should be charged in the off state. 8. The bezel in my case turned out to be unreliable and became loose after a month of use, after 2 months of use there were questions about positioning, I will carry it in for repair. 9. There are no logs of any of the sHealth indicators on the watch, for some reason you have to look at everything on the phone, it's disgustingly inconvenient. 10. There is not enough more flexible button customization, I do not use payments and it would be more convenient for me to reassign a long button hold.
