I've been using the Android OS exclusively and it takes about an hour to customize and configure and since then I've run into no issues.

Depending on your D-pad placement preferences, your favorite screen resolution, and your love or hate for Skittles (I’ll explain later), the 405m may or may not be for you. My recommended settings for Gamecube and Wii emulation on the RG405M is to set the Video Backend to Vulkan and the Shader Compilation Mode to Hybrid Ubershaders. There is always talk around the RH water cooler about “what chip is best, which one is the strongest, which one is your favorite?The same company who had a good thing going for them in devices like the RG350P, RG351MP, RG351V, RG353M, RG353P, RG405M. There are also streaming apps included within the Android 12 OS, but to be honest, due to the size of the screen, I probably wouldn’t recommend using them. I do want to mention that it’s obvious here that ANBERNIC are trying to make their device look better, in my previous reviews i mentioned that I hated the white text slapped onto the face of the device, they have since changed this, and even the small detailing around the buttons adds to the premium nature of this device, making everything look uniform and located naturally, even the internals has been cleaned up.

In terms that I can understand, it is a good enough chip to run things like GC and PS2 games so long as those games are not too hard to run. It is tried-and-true as it resides in the likes of the RP3+ and the PK X18s and at least the former of those two has been wildly successful.

ANBERNIC did install games on the SD-Card too, but this isn’t guaranteed for everyone, as they sent us a review unit and could have done it to get some brownie points from us.
