    Welcome to Android Central! Open Google Play Store, swipe in from the left, tap Settings>Require Authentication for Purchases. Is it set to "For all purchases through Google Play on this device" or something else?

    Ok, try going to Settings>Apps>All, select Google Play Store, and Clear Cache/Clear Data, then Force Stop. Now open it again, make sure those above settings are as we discussed, and see if the problem persists.

    I did what you told me but it is same, the fingerprint symbol is not showing next download.

    Is it maybe reason of my accout?? Because during many test i have tried, i notice that when i deleted my google account which is gmail from the list, i can see the finger print symbol even in device setting like when i decide to add/remove my fingerprint right next to pin password. But i can not get into play store cause no google accout.

    When i add my gmail as a account, somehow the simbol is not showing, only pin password.

    So i even made up the fresh new gmail account and added as google account, it was same thing, simbol is not showing on google play store.

    What should i do... nd is my device has issue or thers is a way that i do not know yet..

    Btw, thank you for reply and helpping me.

    Please help me dont give up please

    You said that this worked before on Google Play Store, then suddenly stopped working, right?

    Try going to Settings>Security and Clear Credentials. Now try again.

    Sorry, not really sure what's going on. Try going to Settings>Apps, select Google Play Store, then Uninstall Updates. Does that change anything? If not, re-update Google Play Store. Still nothing?

    No luck... Still nothing.. Like i said eariler, when i remove my google account which is gmail account, then hidden security feature(symbol of fingerprint) is showig under specific security. I think it has something to do with account but i dont know what that is tho...

    In the Google Play Store settings, uncheck Fingerprint Authentication. Then check it again, and enter your Google password. Does that change anything?

    Sorry that nothing seems to fix it. You might want to consider bringing it back to the store and asking for an exchange.
