iPhone 12 Pro Max Stuttering

Guys, I think I solved it for myself, I had on my main page a third party widget called Weather Line. many times I saw that widget crashing or going crazy, so then it hit me and took the shot, deleted the widget, and reboot, now I have a full day without more stuttering/vibration/laggy swipes up.

Maybe that could help some of you. Good Luck!

I have a newspaper app (Volkskrant, the Netherlands) which makes my iPhone 12 really warm when I use that app. 

I suspect a link to the “stuttering motion when closing an app” problem. 

since 2 days, I kill that App after using it. I have not experienced the stuttering anymore since then, while before, I experienced it multiple times per day. 

so my theory is that the stuttering motion happens because another app in the background (not necessarily the one you are closing) is consuming too much resources.

No, I have those too; but giving it a thought, it would be like a "third party widget" (in my scenario) or some app would hijack your RAM, so I would give it a try deleting huge apps like TikTok, Facebook, even Spotify and reinstall to delete all cache/background processes they could have. then restart.

Hi LJFabian,

Do you have a case or screen protector on your iPhone? If so, do you have the same issue if you remove them? We ask because they can be a source of interference for your device.

Regards.

Here are the last news about my case.

I spoke with technical support by phone and we made every kind of test. I tried with creating a new account witg a new e-mail but the problem was there. I asked to my friends which bought the same phone and i had the chance to test two different devices both with 128 gb. Mine was 256. Well the two devices didn't have any kind of problem after more than half an hour of use. So i decided to go to Rimini apple store. Well they just laughed at me and treated me very bad. As a fool which wants to be too much "precise". And of course they didn' want to substitute the phone.

The only thing i could do was to write to amazon and ask for the phone to be returned. I am waiting for the refund and i will buy a new 12 pro max but 128 Gb. I am starting to think that it could be a problem with the internal storage from 256 up. i heard that many people have problems with 256 and 512. those with no problem, all have 128 gb. I will let you know.

What is your storage size?

I’m having this issue as well and the Genius Bar staff told me that it’s software and Apple should be addressing it soon and that they’re aware of the issue.

I’m on my 4th iPhone replacement and will continue to complain about it until it’s fixed. I’m gonna be a Karen about this because I have nothing else to do in COVID times.

At least the issue was observed by the Genius Bar people when I complained about it the second and third time and they were able to see the issue. So it’s well documented at least. and they observed it after a factory reset so no case, screen protector, or custom apps when the issue occurred.

Changed by sending mine , with a new one!

with 14.5.1 everything is fixed. No stuttering anymore at all!

Same exact issue here too, iPhone 12 Pro Max. The stuttering, when it occurs, seems to turn a “swipe up to go to the Home Screen” gesture into a “bring up the app switcher card view” gesture instead. Which requires me to swipe again to ultimately get to Home. Really frustrating to have to swipe twice, randomly, just to get to the Home Screen.

Hey LJFabian,

Thanks for giving that a try. At this point, we'd recommend connecting with our support team at Contact Apple Support for additional assistance regarding this matter.

Take care.

did you get anywhere with apple on this issue?? I have the exact same issue with my iPhone 12 Pro max. its so frustrating that we have paid for a premium phone and don't have a fix for this even after so many people are brining this issue forward.
