How to change to r15/r6 on mobile in ROBLOX 2020

#roblox if doesnt work, it has to do with the game you are playing. if game creator disabled r6 or r15 in-game then you will be in r6 if they disabled r15 or you will be in r15 if r6 was disabled i made this video 1 year ago and I believe this still works on phone. i might make a ipad version if you guys cant figure it out so just comment if you want me to do It on ipad if you still cant quite get it. music used: i forgot but it was from kinemaster
