Curious to see how well this might work

I'm going to purchase it in the next day or so cause I have plans to use it on Samsung Galaxy S8 with a snap on keyboard cover case.

But maybe installing steam on Linux installed on the Anbernic RG556 and seeing how well that might work on it.

The developer of ApophisOS said it's pretty guided you can choose how much want to debloat and deGoogle.
