Help: a few hours after updating an iPhone 8 Over The Air to 12.2, the screen flashed to solid rows of color bars, which wouldn't go away. Seconds later, the screen turned off. The phone was still on, though, as the capacitive home button was responding and the charge tone was sounding when I plugged the phone in a charger. Rebooting it didn't turn the screen on, nor did plugging into iTunes with Recovery Mode with a full 12.2 Update nor a Restore. The phone is a year old and I was never rough with it. I've scheduled a Genius Bar appointment today, but I'm willing to hear your input.

never install an iOS update on day one. Never. Wait a month for the dust to settle and potential bugs to be worked out. This recommendation is taught in iOS User Guidelines 101.

A month? While doing it on day 1 might not be something for everyone, usually any actual widespread issues already get surfaced the day of the release if not within a few days at most.

Given what happened in this particular thread, who really knows what's behind it all and if it would have happened even without installing a new update or if it would have happened even if the update was installed after waiting for a month.

I always update on day one for the most part and never had issues. Always buy new iPhones day one and never any issues.

Silly myth.

Conclusion: The tests the Apple Store ran were essentially inconclusive, in that it was probably a faulty screen but not a faulty logic board. They tried to change the screen, failed, tried with another one, failed, because they "failed to seat", and I'm guessing they didn't turn on either. Anyway, they gave me a new 8, free under warranty. I updated it to 12.2 via iTunes, partly just to see if the same failure happens again soon after. I find it interesting that there was a recall for logic boards for many 8's. Mine supposedly a few months newer than the flawed batch. FIN

I'm glad you got a new phone, but were you given the option to upgrade to an XS or did this happen before the XS' official release?
