So, I never reply to these threads.... I usually just read and then self diagnosing is my thing—calls to Apple are a last resort. Anyway, I noticed this issue two days ago, and just realized today what was actually taking place. I noticed that when I was watching YouTube and would rotate the the phone for landscape mode, that the stereo channel separation would occur, but only one channel was outputting sound!! I read of the issue tonight on a website which includes a YouTube video—that is mentioned above, and that shows a guy having the same issues with his XS Max. I restarted my phone and it has subsided for now. This definitely seems like a software issue, but for $1,249 US DOLLARS PLUS 7% TAX, I expect not to be having these issues, and also I will not accept a repair, or a refurbished—“new device”. Not with all money JUST spent! This is crazy. Get it together Apple! Charging issues, display color temp issues, and now sound/speaker issues?! I am LIVID! I have had every iPhone since the 4S, multiple devices, don’t make me regret my choices to support this company all of these years! Guaranteed to have spent 25k+ on iPhones in six years. A repair to a brand new, top tier, expensive device, is unacceptable. A smack in the face to your customers—an insult.
