Hello, I have a SM-T820 (galaxy tab S3) and with original software it was very slow.

I read that flashing a chinese rom was giving a much faster device, partly (maybe) because of the absence of google stuff.

I put the chinese Oreo via Odin and it is indeed much much faster.

But I'm concerned with chinese spyware that could be there. Is there any other country firmware that would also have no google stuff and less chance of having spyware?
