I fingerprint sensors on the screen have become common in the Samsung mobile catalog. What started out as an exclusive feature of the brand's more expensive smartphones has now become a feature that some of its cheaper terminals already incorporate as well.
Obviously, not everyone seems to be happy with the on-screen fingerprint sensors of their Samsung terminals. Since Samsung first introduced an ultrasonic fingerprint reader in the Galaxy S10 series, several tests, by both professionals and users, have shown - including ours - that this technology is still far from reaching the level. than that of the sensors for life. And the results aren't much different in optical sensors using the brand's more affordable models.
Ma there may be a solution in able to slightly reduce the error rate e increase speed fingerprint sensors on the screen.
If the fingerprint reader on your Samsung mobile phone screen is not working well, try this trick
First of all it is necessary to keep in mind that although in the XDA-Developers forum there are several users who have assured how this trick has allowed to speed up the response of the fingerprint reader to the unlocking their devices, it has not been possible to prove, and this alleged speed boost is probably nothing more than some kind of placebo effect.
Be that as it may, since the process is straightforward and doesn't seem to affect the operation of the device in any way, it might be worth doing and seeing if it can actually improve sensor operation in some way. The steps to follow for - presumably - speed up the fingerprint reader of any Samsung mobile with an on-screen sensor are the following:
- Open the app System settings and go to the section Applications.
- From the menu at the top right, tap on the option Show all applications.
- In the list of apps, find the app named com.samsung.android.biometrics.app.setting and touch it.
- In the app menu, select the option Battery and then Optimize battery usage.
- In the list, make sure you have the option Tutto selected above and search again for the application you selected in the third step. Finally, uncheck the battery optimization for that app.
As I said, at the time there is no evidence to support this of this trick, although the theory is that disabling battery optimization for the software responsible for keeping the fingerprint reader “active”, the screen of the device is not disabled when the device is turned off and therefore its response is faster since it is not necessary to reactivate the sensor when the screen is turned on again. In our case we carried out this process on a Samsung Galaxy S20 Ultra and a Samsung Galaxy Note10 + and we did not find any appreciable changes in the functioning of the sensor - in both cases they are phones with ultrasonic sensors, so the result could be different in the terminals. with optical reader–.
