Review on Samsung Galaxy S21 5G Factory Unlocked Smartphone in US Version with Pro-Grade Camera, 8K Video, 64MP High Resolution, 128GB Storage, and Phantom Pink Color (SM-G991UZIAXAA) by Kenta Saito

I was one of the first to pre-order this item. Prior to that, there was a Galaxy S7 that served obediently for six years and was, in my opinion, the best phone available at the time. As a result, when it came time to actually use the device, I did not have to worry about selecting a manufacturer, especially after I saw and touched the brand-new s21 on the window display. Nevertheless, not all of the improvements worked out well when compared to the older S7, namely the absence of a headphone port, a memory card slot, a pulse oximeter sensor, and a screen that is a little less vibrant, colorful, and has a lower resolution. They gave me wireless headphones as a gift, but I decided it wasn't scary and 256GB should be enough. I also bought a galaxy watch 3 with a pulse oximeter. Initially, there are still a few drawbacks: you cannot force a connection to the 4g network (with a weak network signal, 2 out of 4x, automatically switches to 3g, at which the data transfer rate can drop to 0), the battery charge is incorrectly displayed (from 100 to 5% it discharges normally, and from 5 to 0%, it discharges abnormally), and pop-up control buttons that are called by swiping from the bottom up (when reading a book, An ate arrived in February with a ton of pointless applications (I don't eat anymore, they say later, and the battery life has gotten worse). Even worse, the phone started to heat up horribly (even while he was just scrolling through the video on the social network, and during video conversations it becomes so hot that it's actually painful to hold in your hands), and then one of the sim cards stopped working (presumably why there are two of them). After the type-c connector quit working, the microphone (there are also two of them; the second one turns on with a speakerphone; I now only speak that way) likewise stopped working (it charges on one side, the other does not, and does not connect to the computer)
