When compared to S9 and S10, the length of the device has become significantly longer. The S-series was well received by customers precisely because of its compact and user-friendly size. Those individuals, for whom it was not important what the dimensions were, purchased the "plus" version. Samsung, I ask that you please get some experience pulling screens on different models.
The fingerprint scanner that was located on the back of the device has been removed. Because it functioned so precisely on the S9, and because placing a finger on it was such a natural motion, there was no need for a separate unlocking procedure. The S20 sub-screen scanner is functional approximately 50% of the time. To get it to function the very first time, you need to go through a full process, including taking aim, calculating the amount of power needed to push, and finding the optimal angle at which to press. Rave! despite the fact that there is not a layer of protective coating on the screen. I have no doubt that Samsung made this decision in order to save money because the under-screen scanner on the P40 functions normally (albeit it is not quite as good as the scanner on the S9). To Samsung's credit, after one of the tests, the scanner's performance grew noticeably worse, despite the fact that it had previously been subpar.
Eliminated the need for a retinal scan. It was possible to unlock the device even when wearing a mask and without having to make contact with the screen. A tremendously helpful function has been rendered useless due to an excessively large screen that is not located in the appropriate location.
The camera block started protruding more and further out of the gadget. And this is not the price to pay for a considerable boost in photo quality, as is the case with the Nokia 808 and other phones that have a large camera matrix and/or a flash. The photos are only somewhat better than those on the Galaxy S9. Also, the camera (or cameras) performs poorly in a number of different criteria, such as focussing when the subject is up close.
The additional button on the side of the phone was eliminated as a result of the efforts of people who dislike Bixby. Only Sony, one of the flagship manufacturers, has an additional side button (for taking images), but in my perspective, it is impossible to remap it without having root access. Here S8, S9, S10 were unique. On my S9, pressing the button simultaneously brought up the "home" and "back" menus. Imagine that you have forgotten how you normally handle the most fundamental of orders. It is difficult for me to adjust to this new routine. It does not appear that anyone has a problem with Samsung in this area; it is quite improbable that many individuals have utilized this key. However since this is my evaluation, I will focus on how the event impacted me personally.
