As usual, PBKreviews videos are very detailed and highlight the key features of the smartphone unlocking phase. This is even more interesting information in this regard, as it allows us to understand what the differences are between the top and bottom variants of the S21 series, as these smartphones are not only in the technical datasheet, but also due to the build quality that characterizes them.
The plastic back of the S21, in fact, leads to a Very traditional glass panel, It turns out Slightly harder to remove. Opening the smartphone also shows why the rear camera module – covered with metal plate – was not made into a piece with an aluminum edge.

There is also a thorough examination of the photo gallery – it presents 3 cameras are confirmed in 4 (Periscopic only one, not for obvious reasons) and various solutions for heat dissipation adopted by Samsung.
Overall the S21 Ultra achieves a repair score of less than 7.5 on the S21 at 10 points, 6 Your 10. Among the most criticized features we find the most difficult to access is changing the screen (its flex is welded to the panel, not removed on the S21) and Battery – It does not yet have the classic adhesive tabs – in addition to the initial problems when removing the rear window.
