If it is on the Qubino side, then it probably won't get fixed. First you would need to make sure that Qubino has fixed that bug and then you would need to send the device to them for them to update the firmware.

Our Flush devices don’t support over-the-air (OTA) software updates (SW). Updates can be done through a custom tool and a software. We can do the updates for free; you only need to cover the shipping costs. In some cases, our official distributors offer the option to do it.
