Starting today the eager fans can download the beta version of the Android 6.0 Marshmallow build for the Ulefone Vienna from the official blog site of the manufacturer. The final build is going to be released soon via OTA so this one is only for the impatient or curious ones.
Keep in mind the whole OTA process is not enabled in this beta build so you would need to flash the final anyway once again when it’s released. But to scout the new features like multitask windows, new graphics in the Settings or manual mode in camera app it’s the perfect opportunity.
Ulefone formerly promised the final Marshmallow build to be released by the end of June and then corrected themselves with an issued apology and announced delay. But now with beta already out it seems the delay is not going to be that significant hopefully. For now you can check the following video showing the beta Marshmallow running on the Vienna.
