I'll write perhaps the experience of using this firmware (which is currently for August 2021) on SHIELD Tablet 32gb
I'll start right away with what idea the tablet was created with. Games:
I will describe it in general terms, good, but not very good. Some games may require some kind of library, such as Half-Life 2, Half-Life 2 ep.1, Half-Life 2 ep.2 and Portal.
But games like Borderlands 2, Borderlands Pre-Siquel, Grand Theft Auto (VC, SA, III, LCS, CTW), World of Tanks Blitz, Super Meat Boy, Max Payne, Trine 2, Talos Principle, Contrast work great, very pleasant response, very good performance, but also very good heating and fast battery discharge) Bully, by the way, the same works, but at medium graphics settings, at high it slows down very much (
The EPSXE emulator works without question. Most likely PPSSPP and other emulators will work the same without problems, I honestly did not have time to check it yet)
But Doom 3 BFG Edition crashes with an error almost immediately, ARK Survival Evolve at startup gives a loading screen and almost immediately a black screen and it is not clear that the tablet is still working or has already turned off / restarted.
Multimedia
Usually I usually listen to music in VKontakte, I can also watch movies there sometimes, watch videos on Youtube (Vanced) and sometimes watch TV shows and movies through Chrome. There are no problems with music (although I would like to have a more powerful sound), but with video there are often problems, and specifically video artifacts, apparently OMX works, but not stable)
I don't really use the camera, I won't say the same about autonomy, I'm still waiting for normal battery.
I also installed some Google applications in GO versions (Gmail Go, Maps Go, Galerey Go, Google Go, etc.), it seems like applications are web versions of full-fledged applications, take up less space, require less power and, in principle, work well. (it would be a shame that Chrome Go would be there, otherwise this one is eating resources just unmeasuredly, it always has little RAM xD)
Visually, I accelerated the system by setting the animation to 0.5 for all three parameters in the developers menu, using Nova as a launcher.
The system as a whole works very quickly, and if you set the animations to 0.5, then it's generally a fairy tale, but the stability leaves much to be desired, the application can start the current from the 4th time, before that it crashes, with various errors, or it can start and work right the first time.
In general, in some moments the firmware is very good, and in some it is not very good.
I can't say anything about autonomy, there are no normal batteries (
