It has become the main mobile phone of Xiaobian. These are the three biggest advantages and three biggest disadvantages found by Xiaobian after using Galaxy S20 ultra for a week. < / P > < p > in the years after the launch of Galaxy S and Galaxy note phones, many experts and users have noticed that the screen of mobile phones is almost the most important place to enhance the beauty of mobile phones. Although each new generation seems to be a little better than the previous generation in terms of online data, in fact, any leap in quality is invisible to the naked eye. < / P > < p > based on this, the galaxy S20 ultra screen is a revolution. This is an important step forward. AMOLED technology + 120 Hz refresh rate + 1440 x 3200 resolution = absolutely excellent image quality. There is nothing to complain about. < / P > < p > first of all, Xiaobian of course noticed the frequency of 120 Hz, and then it was difficult to return the standard frequency to the screen. The smoothness of the picture gives the illusion that the mobile phone works twice as fast. It’s like the veil has subsided, the vision is clear. From another world, from another galaxy, the screen doesn’t even look real. It’s hard to explain this in words, you just need to experience it yourself. < / P > < p > although there is a small problem – currently, the 120 Hz mode can only be used if the resolution is limited to FHD +. But even at lower resolutions, the screen looks incredibly clear. < / P > < p > in addition, the most impressive thing is that Samsung has better optimized the “natural color” mode in its color settings. In this mode, the screen appears to be over saturated. Now I really like it. < / P > < p > by the way, the editor must also praise the stereo speakers. Because of the size of smartphones, they are magnified, which may also help them. Stereo is clear and rich. < / P > < p > the large screen is ideal for multimedia and applications because it can display more content. Unfortunately, not everyone will like the size of a mobile phone. Do not use with one hand. It’s impossible. < / P > < p > the fact is, because the aspect ratio of the screen is 20:9, it is not realistic to reach the top notification bar. The screen is not too wide, but it’s very long. Thus, it will often be touched by mistake. < / P > < p > in addition, the phone’s body is quite large. The galaxy S20 ultra is very heavy. Its thickness is almost 9 mm and its mass is just 222 G. Compared with the previous Galaxy S10 model, the weight of the phone is really large. The first impression of the lens is very, very good. The lens works well in bad conditions. This is largely due to the highly efficient automatic HDR algorithm. < / P > < p > ultra wide angle lens is a great choice for a group of mobile photographers. During the day, it produces results at the main module level, but it’s worth noting that it works much worse at night. < / P > < p > the telephoto lens should have additional digital zoom. Samsung has greatly increased the focal length – up to 103mm. Compared with the basic lens, it can provide 4x zoom, although in the application, after switching to the telephoto lens, the lens will use 5x zoom, so it can carry out slight digital zoom. The photos taken during the day with this lens are great! No < / P > < p > the quality of the photos is really praiseworthy. The 108 megapixel module can complete its work. The details of the objects in the photos are amazing. You can see it for yourself. < / P > < p > of course, it’s worth remembering the possibility of recording 8K resolution video. Are these videos an advantage of mobile phones? Xiaobian doesn’t think so. Of course, 8K TVs are now available, but they are less common. < p > < p > Xiaobian doesn’t think that 8K recording is defective, but Xiaobian thinks that shooting video at 4K @ 60fps will be suitable for most of the current users. The image quality is very similar to 8K mode, and the smoothness is much better. What about the famous 100x zoom? Samsung likes to mention it in marketing. In addition – information about recording zoom can be found in the camera block next to the telephoto lens. < / P > < p > when a mobile phone has a huge display screen with frequencies up to 120 Hz, very high performance and many different functions, people have to doubt the service life of their mobile phones. But the Samsung Galaxy S20 ultra is really good. A battery with a capacity of 5000 MAH can last a whole day. < / P > < p > no matter how Xiaobian uses it, the power of this mobile phone can last until the evening, which makes Xiaobian feel surprised. For such a powerful flagship, this is a good result. < / P > < p > the fingerprint scanner is located at a very convenient height on the screen and covers a considerable area of the front panel. It’s rarely missed, but the accuracy of touch is not a problem here. Ultrasonic scanners work only when there is strong pressure on the screen. In order for all operations to work quickly and reliably, you need to press your fingers very hard on the glass. So uncomfortable, unusual and a little unnatural. < / P > < p > in terms of performance, this phone is really great. Everything was running smoothly, quickly and without any slowing down. This is not surprising, because of the modern and efficient high-tech Xiaolong 865 processor + 12 GB lpddr5 ram + fast UFS 3.0 storage + microSD slot + AMOLED HDR 120 Hz display + optimized Android 10 system. < / P > < p > in addition, Samsung flagship has the latest design and high-quality body materials. The Korean company uses a flat screen with 2.5D curved glass. Surprisingly, although it looks more modern, the phone has not lost its features and is very similar to the galaxy S10 series. This mobile phone is still very good in summary= https://twhosting.com/american-companies-begin-to-give-up-r-d-who-should-pay-for-corporate-research/ target=_ blank>American companies begin to give up R & D: who should pay for corporate research?
