Samsung Galaxy S8 was launched on the market without one of the most expected functions by customers from all over the world, namely, a fingerprint reader integrated into the screen. Many people expected the Samsung Galaxy S8 to have a fingerprint reader integrated in the screen to facilitate biometric security, but in the end Samsung integrated it in the case, next to the camera.
The decision was highly criticized by many customers, but those from Samsung chose to take it because they had no other solution for the Samsung Galaxy S8. According to a person with knowledge of the project to implement the fingerprint reader in the Samsung Galaxy S8 screen, Samsung failed to solve a major problem for this technology.
More precisely, the integration of the fingerprint reader in the Samsung Galaxy S8 screen had the effect of displaying a higher brightness in the portion of the screen where it was placed. We don't have any image to show us how big the difference was in the Samsung Galaxy S8 screen between regions with or without a fingerprint reader, but the differences were probably big.
Samsung Galaxy S8 - lack of much desired function
Considering the very big problems of the Samsung Galaxy Note 7, it is very easy to understand why the Samsung company decided not to use this imperfect technology in the Samsung Galaxy S8. If it had been chosen to implement the optical fingerprint reader in the Samsung Galaxy S8 screen and the brightness would have been different by region, the scandal that would have engulfed Samsung would have been huge.
By abandoning the implementation in the Samsung Galaxy S8, those from Samsung could also abandon the use in the Samsung Galaxy Note 8, because the technology would not be ready yet. It is speculated that this technology, which did not reach the Samsung Galaxy S8, could reach the Samsung Galaxy S9, but of course everything depends on how it could be completed so far.
These rumors regarding the Samsung Galaxy S8 problems question the integration of a fingerprint reader in the iPhone 8 screen, Apple seems to have found a solution for this. If there were differences in brightness for the screen on the Samsung Galaxy S8, it will be interesting to see if Apple's implementation for the iPhone 8, which seems to be 100% safe, will be free of problems.
