First off, the Galaxy S7 is gone. Returned to AT&T yesterday and I have my Note 7 replacement back. Thank goodness. However I am thinking the lock-out must be some kind of setting I should be able to turn off, because the Note 7 that was returned under the recall did the same to me at least once. Generally my fingerprints register and are read very well by Samsung phones. But occasionally if I've been doing a lot of chores and had to wash my hands a lot, the sensor will not read my prints. Even on a good day it can take me a couple of tries to get my finger set on the reader properly. Anyway, after a certain number of attempts the phone will send up a message of try again in 30 seconds. If I try again, and my print fails even after one try, the message tacks on time to wait a full minute. Now I'm no dummy, of course by that point I would try to enter my PIN number, but the problem is when I touched the home button to enter it, that touch registered as an attempt to use my fingerprint and the message pops up adding minutes. I got it to go up to an hour. If you will notice the time on the clock, I actually was locked out longer than an hour. The phone logged each touch on the fingerprint sensor and added a greater lockout penalty each time. Of course I realize now I could have used the power button instead of the home button to bring up the prompt to enter my pin, but coming from IPhone muscle memory was so ingrained to use the home button. I rarely use the power button except to turn off the display. I did reboot the phone to no avail. At any rate I was just wondering why the Samsung phones do this. Is this an Android feature or is it specific to the Galaxy range? If it's some sort of security feature I have to say I can't see the point of it. How do I turn it off if it is some sort of setting? iPhones don't care how many times I try to use my prints, they will always make available the option to log in using a pin if I had set one up.
