Tech Times is reporting that many Samsung users who have upgraded to Marshmallow are finding themselves unable to unlock their phones. While obviously not affecting all users, enough users of the Samsung Galaxy S6, Galaxy S7, Galaxy Note 4 and Galaxy Note 5 to warrant a warning for users of these devices to not upgrade to Marshmallow.
Users that are being affected by this glitch find that they are unable to unlock their phones. Those using the fingerprint sensors to unlock their phones are finding the sensor no longer recognizes their fingerprints, and seemingly stops trying to read them altogether.
Suggested fixes for users;
1: Don’t upgrade
2: Turn off password and fingerprint authentication
3: Use the Samsung Find My Mobile Website to unlock the phone, provided the user has a Samsung account and the device is connected to it.
Finally, if none of these work, the user needs to contact Samsung customer service. Good luck!
Apparently encryption is at the heart of the problem. Some glitch with the OS update is causing the phone to “mess up” the encrypted fingerprints stored within the phones. There are also reports of other manufacturers devices being affected by the issue.
As we watch phone after phone being disabled by OS updates, I for one am glad that BlackBerry takes the required time to test and ensure that our updates work, and work well.
