Samsung GALAXY S10 was launched with a new type of ultrasonic fingerprint reader, integrated into the phone screen, allowing the fingerprint to be scanned through the screen, just like in the case of other mobile phone models. Unlike optical fingerprint readers, the one used in the Samsung GALAXY S10 can be recognized much easier, but also much faster, but of course it is not perfect, so in the video clip below we can see its problems.
Samsung GALAXY S10 it is tested together with the OnePlus 6T to show the difference in terms of unlocking when the fingers are wet, the ultrasonic reader being clearly superior to the optical one, as we already knew. There are no problems with unlocking the Samsung GALAXY S10 if the finger is wet, but it would have been interesting to see if scanning would have been possible in the situation where there would have been water on the screen, and if the fingerprint reader would still have worked. .
The Samsung GALAXY S10 has an imperfect fingerprint reader
Samsung GALAXY S10 it has no problems with the plastic films applied over the screen, as suggested by some manufacturers of accessories for mobile phones, unlocking can be done very easily under these conditions. Unfortunately, it seems that using a glass protective film for the Samsung GALAXY S10 screen is not such a good idea, because unlocking is impossible, so either avoid them completely, or buy the ones that have a hole in the area the fingerprint reader.
Samsung GALAXY S10 was presented by Samsung without providing information about the problems that may arise if glass films are used, but some kind of protection was still offered. The sale of the Samsung GALAXY S10 by Samsung partners is not done with glass protective films either, the sellers being instructed to recommend only the plastic ones, at least at mobile phone operators, or other types of partner stores.
Samsung GALAXY S10 it suffers from a problem that some expected for these devices, and that's because ultrasonic fingerprint readers aren't perfect yet.
