S4 forgets pin

[choirmama]

Sometimes when I try to open up my phone, and enter the PIN, it tells me it's incorrect multiple times. I have to restart the phone, and then it recognizes the PIN. It is happening more often- twice today. Does anyone else have this issue, or know how to fix it?

Thanks.
