Screen issues on iPhone 13 Pro Max after iOS 26 update

Yeah man, I’ve had iPhones since the 3G, and I’ve gotta say that this update has put me off ever going forward with a new version right away. This has not exactly bricked my phone, but iOS 26 has definitely ruined it to the point of making it unusable. My cameras no longer work, my frame rate has dropped to about 10fps, and apps are constantly crashing - ones like “messages” and “settings”. This is absolutely the worst update they’ve had; not to mention my Apple TV and iPad are also now bugging out. On my phone, it now says that I don’t have Apple genuine parts installed, even though my phone has never been repaired and worked absolutely fine in iOS 18. I’m not the only person reporting errors with this update, and even after waiting for the 26.1 update my issues not only persist, but are noticeably worse. On the phone with Apple support and after escalation they let me know that it’s a problem they’re aware of with my model - 13 Pro Max - and that there’s nothing they can do but wait for another software update. So, now, I get to upgrade to a 17 Pro Max and hope for the best.
