Today Samsung officially announced the worldwide availability of both Marshmallow updates for the Galaxy S6 and Galaxy S6 edge. Users on both devices should be getting the notification very soon, if not already.
Of course, the upgrades will become available gradually, and it will depend on the market and carrier.
The Android Marshmallow update for the Galaxy S6 brings the new Android version, enhanced TouchWiz interface and all the latest security fixes. The Galaxy S6 edge will also benefit from it with new edge screen features.
If you own a Galaxy S6 or S6 edge, you should probably keep an eye for the update pop up.
