Thanks for your reply.Please restart the iPhone first. How long do you have it in use, is it the first day? Which iOS version are you running it on?
NOHave you tried a fresh reinstall of the OS?
That's your best guess, OP - update to the newest iOS version first and see if that behaviour persists. If not, go on as described by 1rottenapple.That weird my phone xs max doesn’t hang at all. Everything launches quickly. Really the only solution is reset the phone to factory and start adding apps slowly to see how the phone behaves.
