The amount of tech turned from idea to actually manufactured in order to reach the holy grail of "full screen cover" is impressive. Ultrasonic fingerprint reader, under the screen camera and sensors, ... I am not sure I buy into the need for it on my cellphone; while I'm not like a lot of people from HN and actually enjoy a large phone and I was one of the first Note customers, lately I switched from a S9+ to a S10+ and I actually prefered the 9's screen compared to the infinity display with its hole (or concurrent and their notch), so I guess I need to wait until they finally figure out how to not need such tricks. But despite not feeling like I need / like it, I can't stop but be impressed at the tech and the speed at wich it is made. The first Galaxy S phone was barely ten years ago.
