Geek answer
So the file will is about 3,000 pixels across when square and your printing 24 inches wide so that is 125 dpi which isn’t alot. I’ve just had a couple of prints done from a 12MP dslr. They are 16 by 24 inches. That’s 166 dpi and its till quite good close up
But what actually matters is whether the resolution matches the content. If its a dreamy sunset no problem. If its 100 of your best mates your stuffed. Also being from a phone its the quality of those pixels that will really make or break it
Any chance of showing us the file? I think I could give some feed back. Or crop a bit out and get it printed at the same magnification for under a quid and see how you feel about it
