I have set 4 fingerprints on my new max pro but they are unrecognised. They have worked one day. I have tried to cancel them bit I scarcely manage to set new ones. I have also tried to switch off the mobile. What should I do?

    Hi rossi.antonietta68

    What's your phone’s firmware version (Settings > About phone> Build number)
    Go to Calculator=>type " .12345+= "You will be entered to SMMI_TEST
    Please check it in safe mode. (https://www.asus.com/support/faq/1005163)

    Sorry for any inconvenience this may cause.

    The problem with the fingerprint scanner is present in many users. It does not depend on the firmware. I had this problem both on android 8.1 (340) and it persisted on android 9 (055). It seems that the scanner goes into sleep, and ceases to respond to the print. After 5-10 seconds, it starts working again. Because of this, and the problem with entering new prints, the scanner falls asleep, and does not respond to touch several times in a row.

    This problem started with 340 firmware. At 327, everything worked well.

    On our forum they write that the problem is because of this:

    "We have two types of fingerprint scanners, goodix and cdfinger. You seem cdfinger. If yes, what is the problem Asus and their curves library. During the long sleep is accumulated in the queue scanner bunch SIGIO, scanner libraries are beginning a very long time to wake up the scanner to operate prematurely. This can be in the logs to see if, after switching off the screen in the logs of a long run cdfinger posts, cdfingerTA - this is it. Normally, the log should calm down immediately, but sometimes it happens."

    I have cdfinger. With Android 8.1 there was a long wake up. On Android 9.0 if not recognized at first touch, then the scanner no longer works at all

    Exactly the same problem, if you put the “wrong” finger for the first time, the phone will respond with vibration, but will not unlock. But if you immediately attach the correct one, then nothing happens, the scanner seems to fall asleep. And unlock the phone only after 5-10 seconds. This is very annoying!

    In the latest firmware (Android 9, version 057), the problem remains.

    When checking in the SMMI_TEST, it shows that everything is fine, there are no problems:

    I put the phone in safe mode - the problem remains. The fingerprint scanner also falls asleep, and if the finger was not recognized the first time, the fingerprint scanner falls asleep, and no longer responds to the finger.
    He wakes up after 5-10 seconds., And so it repeats constantly.

    I have a fingerprint scanner model "Goodix", firmware latest version 057.
