Many Android phones and tablets can do Tidal MQA using USB Audio Player Pro (UAPP) with an MQA-capable DAC such as the Meridian Explorer2. There are other ways too, with a phone alone. In fact, the latest LG V30 can do MQA right in UAPP--UAPP is touting this as an integration of UAPP and the LG V30 as part of their new UAPP 4.xx Android software.
As far as I know, for now, the regular Tidal Android app doesn't do MQA in Android but I don't know what the LG V30 can do visa-vis the Tidal app alone; I think even it would need UAPP to give a full Tidal MQA decode. I think a lot of people wish Tidal would enable MQA in their Android app but they haven't done it yet. I'm sure that makes the folks at UAPP happy, then again they're paying for the MQA license I would assume.
In my case I have a Tegra tablet hooked up to a Meridian Explorer2 DAC via OTG cable. In UAPP I get a full decode of Tidal MQA files (blue or green lights light up when streaming MQA). The UAPP 4.xx iteration even shows in their software player under the album art the bitrate and the fact that you are streaming an MQA file. The key thing in the UAPP settings is that you have to enable bit perfect to the DAC. There is at least one you tube video where a guy demonstrates with his regular Android smart phone hooked up to his ME2 that he's decoding an MQA file and it's outputting out of the headphone out in his ME2. That's where I discovered it.
