Gruss Susanne in business could not weiterhelfen.Schönes mess when their own cell phones do not know me.
Welcome to the forum
your title was not entirely conclusive, so I have adapted this somewhat.
Please try to choose a more descriptive thread title the next time - to make sure to read this thread through.
In my S6 I have to first enter the four-digit PIN on the SIM card and the security password, which you must specify when fingerprint after a restart ...
The fingerprint is only one alternative to the device PIN, never absolutely necessary to unlock. Depending on your settings, it may be that you need to enter two different PINs and have used the wrong: If the SIM card lock is active (which is usually the case), the device asks first for the PIN of the SIM card, then for the PIN of the device (if you have this locking method enabled).
