Good news! From now on, our mammoth battery device Ulefone Power will have Android 6.0 pre-installed out of factory. So if you will buy it now, you’ll be able to taste the Marshmallow at the very moment when you open the package.
The Android 6.0 pre-installed on the new power will be a stable version. This version of firmware will be released OTA soon to old devices which have been upgraded to Android 6.0 by USB flash. For those who have not upgraded their Power from Android 5.1 to 6.0 we are still working on the OTA upgrade and will release it as soon as we can. Please, be more patient.
