PC versions of SA-MP and MTA are possible on Android using ExaGear SU. That application is based on Wine (a thing for Linux) and it can run native *.exe files on Android but for games it needs to be configured (that may be not easy). Check YouTube for more...
( for example - MTA https://www.youtube.com/watch?v=0A17s5o6Sao Stalker LA: DC https://www.youtube.com/watch?v=u1_xLb7KHbU )
P.S. I also found unofficial port of MTA SA on android, that based on mobile samp, i downloaded it from GitLab but couldn't launch. Maybe it's fake, but one brazilian tested it on YT, idk
