Android 5.1 for S6 and S6 Edge to reportedly bring Guest Mode
Guest Mode enables you to set up separate profiles for guests, allowing you to share your device without worrying about your personal stuff, including installed apps, being seen by others. The feature was first introduced for tablets with the Jelly Bean update but arrived on phones with Android Lollipop.
It isn't yet clear when the update will roll out to the devices. Meanwhile, a Samsung Galaxy S6 edge for T-Mobile has been caught getting Android 5.1.1.Via
