Before you jump in on the next update for your Samsung Galaxy S7, Galaxy S6, Note 5, or Note 4, pay heed: there's an issue. Users with a variety of Samsung smartphone updating to the first release of Android 6.0 Marshmallow have been experiencing a unique issue. Passwords on the device - be they text based or fingerprint based - seem to be lost or distorted as the newest update is installed. But what about you? Will you see the same issue? Should you be fully freaking out at the moment, or is there something you might do to avoid this mess?
