Android Marshmallow update causes problems to multiple Galaxy devices
Android Marshmallow has been around for a while, but the latest problems apparently caused by it seem to be the most serious so far. While such problems usually occur for a limited number or handsets and models, this time the issues plague multiple devices, according to the user reports recently posted on Reddit.
So far, the list of affected devices includes the Samsung Galaxy S6 and Galaxy S7 smartphones, as well as the Galaxy Note 4 and Galaxy Note 5 phablets. The users who updated these devices to Android Marshmallow for the first time ended up with a locked device, as both their old fingerprints and passwords are no longer accepted once the new firmware loads.
To make this even worse, it looks like Android-powered devices from other brands are affected as well. To avoid such a problem, the easiest thing to do is to remove both password and fingerprint logins before installing Marshmallow. Those who are already in trouble should go to findmymobile.samsung.com, lock and then unlock their device. If someone who is facing this problem does not have a Samsung account associated with the affected device, then the only thing left to do is to contact Samsung support.
Samsung has not made any public statement concerning this issue for now, but we will keep you posted, so stay tuned.
