Oukitel are currently developing Android 6.0 Marshmallow for the K10000.
After the launch of Android 6.0 Marshmallow, big brands started working on the development immediately. And some small Chinese smartphone brands kept announcing that they will release the update. However, just a few brands kept their words. It's glad to see that Oukitel keeps the promise and devote the sources to deliver better user experience. They released a short video shows that the K10000 is running Marshmallow. Customers will get the Android 6.0 update via OTA soon as the engineers are optimizing the ROM.
