There is more and more information on the Galaxy S10 coming out early next year. It is believed that this time Samsung will offer not two, but three models. They will feature under-screen fingerprint scanners for the first time.
Previously, it was assumed that this refers to the two more expensive smartphones. Now information has come from South Korea that the scanner will be on all three smartphones.
In addition to the device at a lower price, Samsung will release smartphones to replace the Galaxy S9 and S9 +. They will have 6.2 and 6.44 inch Infinity Displays with curved sides.
In July, there was news that the fingerprint scanner on the cheap model will be located on the frame of the case. Now the scanner is in the back. Now last month's news is being refuted. However, while all three models will get an in-screen scanner, they won't be the same. The two more expensive smartphones should get an ultrasound scanner, while the budget version is content with an optical scanner.
What is an ultrasound scanner anyway?
No, this is not a military development that will rip your finger off. An ultrasound scanner transmits a pulse that marks the pores and edges of the finger that are unique to each person. These sensors are more accurate than optical sensors due to the 3D fingerprint map.
The optical sensor works like a digital camera. It creates a two-dimensional image of the print. Accuracy is reduced if the finger is wet, dirty or too dry. External light sources can also damage recognition.
This is not to say that optical scanners are completely useless. Chinese manufacturers are already releasing smartphones with this technology. It is three times more expensive than ultrasound scanners.
By the way, Samsung has not yet confirmed work on three S10s, let alone details of their specifications.
