I have just bought the ASUS max pro m2 2 days ago and the fingerprint sensor is not working.

I have checked for firmware updates and it says its the latest. The internet is full of fingerprint sensor issues with the max pro m1 but I havent found anything regarding max pro m2.

is this an expected issue that will be solved via fota or should I go to asus service?

I enabled developer options and generated a bug report.
I see the following error multiple times in the bug report text:
12-20 11:27:51.616  1000  1384  1868 W FingerprintService: fingerprint HIDL not available

This is the truth of Asus phones.
All of their phones are full of bugs.
It's been 8-9 months when ASUS max pro m1 launched and still this device has lots of bugs .

 Every new update creates new bugs.

All max pro m2 users get ready for endless bugs.
@rajatagrawal.web It must be hardware fault. You should get replacement of the phone on flipkart.

Hi Rajatagrawal.web,

Most of the time fingerprint sensor issue occurred due to dusty surface of the sensor.
Please make sure the surface area of fingerprint sensor should be clean

However, We need your help to explain exact issue you are facing with the fingerprint.
1. Fingerprint completely not working? or
2. Intermittent working issue with fingerprint sensor.

You can check the hardware by run the SMMI test.
Open calculator -->input ".12345+="-->run the test for fingerprint.

Also please update the unit with latest firmware version i.e. "OPM1.ww_phone-15.2016.1812.179-20181227"

Manual FOTA Update steps-->
You can also go to ASUS official website to download newer firmware and instruction manual.

    Please make sure the firmware SKU you download is conformed to what on your phone, eg., WW -> WW, CN -> CN, TW -> TW. Incorrect SKU will lead to update failure.
    You can not change the SKU from one to another, eg., WW -> TW, and also can not downgrade your firmware, eg., V2.20.40.13 -> V2.19.40.18.
    During update process, please charge your phone with AC adaptor or make sure the phone has at least 15% battery life.

Steps for update:
1. Go to "Need Help?" page of ASUS official website to download ZIP file of firmware.
    Note: Double click the ZIP file after downloading is completed. If the content is another intact ZIP file (as shown in red on picture below),
              please upzip the file again.
             If the content is not an intact ZIP file (as shown in yellow), you do not have to do anything.
             Close the ZIP file after check.

2. Connect your phone with PC via micro USB cable, and copy the ZIP file to the root directory of internal storage of phone.

3. Detach micro USB cable from the phone to make the notification for firmware update poped up on status bar.

4. Tap "System Update File Detected..." and follow steps to update firmware.

Note: Steps or photos shown above may have variation by different models.

For some upgraded versions that have great difference, e.g., from Jelly Bean (Android 4.3) to KitKat (Android 4.4),
you may need to upgrade to a "bridge version" in advance to proceed.
Please see picture below for example.
