It seems like that I faked the run now since the video proof won't show up.

Also, why isn't the mobile port of Sonic The Hedgehog here?

Awnser for question 2

Probibly because it is not official a random company probibly posted it

I used the official app on the playstore made by Sega

I don't know then

Sonic 1 (2013) mobile port can be found here: https://www.speedrun.com/s12013

I don't think the mobile port's allowed though, since it has patches and includes Spindash [you can turn off the Spindash though]

s1 2013 have own boards to speedrun here, install a emulator and the game rom.
