Less than 1GB of memory usage, fast to start, good performance, extremely fluid interface, simple, minimalist and clean, less than 8GB of required space, CPU usage seemed to be a little high, I do not know why, but this does not make much difference, detected all the hardware. Update on games : Kings Bounty Legions don't work, so I tested a racing game, Pocket Rally, worked, but looks like from 1998, and Mupen64 emulator, tested Top Gear Rally, it worked too. I did not create an account on Google, I skipped the steps, I used ApkPure to download the apps, this don't require an account to download the apps, all apps are very small in size. If you remove GooglePlay Services it will probably use even less ram, but maybe some or many apps will not work anymore. So, I was impressed with the performance and simplicity of Android version 9, but Windows 10 is the opposite of this, bloated, memory devourer, big space requirements, etc. I used the Android 9 x86 64 bits, via an USB pen drive as Live test, created in Windows via Rufus USB, so I don't installed it, if I install it will have better performance. I have an Intel i5 8250u, 8GB ram, 512GB SSD.
