Yes you heard that right. Although the latest S series flagship from Samsung – the Galaxy S6 and S6 Edge has yet to receive official Android 6.0 Marshmallow upgrade, one of the luckiest Samsung Galaxy S5 user has received the official firmware upgrade and even demonstrated it in a video.
The firmware of the Samsung Galaxy S5 of this video uploader belongs to official upgrade. However this firmware belongs in development period, and it shouldn’t be available to public consumer of the Galaxy S5 right now. Samsung has yet to provide feedback on this matter but we could assume that this video uploader could be part of the Samsung firmware development team.
Based on the date listed on the screenshots of the firmware above, the Android Marshmallow upgrade for the Samsung Galaxy S5 has yet to be released publicly.
If you are also one of the lucky one that receive the official Android 6.0 upgrade in your Galaxy S5, do not panic as the worst thing that can happen is bug and the official Android Marshmallow will be online during next year.
