Back story: I am to give a 3 minute pitch on a task i worked on.
I would like to something like, "As a general knowledge, we know that smartphones are dominated by IOS and android. Which is why working on these operating systems are important"
Something like that... But i don't know if i have to give like a solid quote from a credible source or i can just throw the word "allegedly" in there.
Please help me with constructing this sentence!
Thanks and with Love, English newbie <3
