I would like to know if is it possible to upgrade the Android 4.2.2 to 4.3 on the ulefone U9592? Or install the Android 4.3? And how can I do it?
It is impossibile to do that at this moment. There are some rumours about Android 4.4 for mtk6592 processors but we will se when will that come true.
Thanks a lot. I'm waiting for that. Because I want to use de Bluetooth 4.0.
