Is anyone having issues with iOS 15?

Clokwork

I am attempting to rollback though it is not supported and unfortunately the 14.x versions are unsigned by apple, so I will see if this works. I called support and they are only tier 1. They were unhelpful unfortunately. I would really like to find a way to open a discussion with someone higher up.

I had the same, that was the moment i stopped using the 8, which was the only usable device for me. Unfortunatly there is no way to go back to older unsigned versions without saved blobs. Forget about that…

Using a poco m3 pro which is the only phone i found that is not giving me any problems.

Another misfortunate report in Russian (original post)

Just the other day I accidentally updated my ipad 5th gen to the latest ios 15.1 or 15.2 (thanks to Appple for the small non-swipeable banners with the early morning update). Before that, it was 14.1 for a long time. Now I feel mild discomfort.

And update in few days:

Feeling discomfort, don't want to use it and can't use it now.

Mrak0020 I am trying to figure out what could have changed in the software that causes issues with some of us. I thought I was safe with my old device but apparently not.

I would love to A/B devices before and after iOS 15 with respect to PWM and FRC.

the iPhone 12 was known for low PWM frequency.

Pure speculation alert! Apple could have changed the dimming algorithms

Did anyone try "differentiate without color" as recommended in this post?

Clokwork

ryans I was on the phone with accessibility personnel at apple once and I tried everything. There's nothing baked into the current OS that can help me with what they've changed.

Clokwork Yup, exactly the same for me. My iPad Pro 12.9 was pretty good on all iPad Os’s prior to 15, but 15 causes me eyestrain/ cloudy head/ headache fairly quickly. Unexpected and unwelcome! Have tried various different setting including differentiate without colour, but no improvement for me. What ‘improvement’ did Apple make here?!

ryans

FNP7 Highly suggest calling Apple Accessibility! You speak to an actual human about this and the more noise we make, the more Apple will be inclined to do something.

Please call them!

ryans I’ve tried calling Apple on this a few years ago, without success. The support people have a script and generally seem to know far less about the specific problem here than we will, based on individual research, not helped by the facts that a) there is no accepted diagnosis for the issue and b) tens of millions of Apple users have a problem-free experience with its products and c) this isn’t an Apple-specific problem. If someone on here reports success from calling Apple, though, I’ll definitely try that again, but otherwise wouldn’t waste my time.

I was starting to wonder if it was the newer hardware causing the issue, but the way I feel looking at my iPad Pro on iOS 15 is the exact same way I feel when I look at any current I-device. It was almost instantly familiar once the update was complete.

That said, I don't believe it to be specific to newer apple hardware. I truly believe it is all software related at this point.

FNP7

Clokwork software definitely plays a key role here, evidenced by the iPad OS15 issue here, but also for me different comfort experiences using the same monitor or TV with different inputs. Not sure I know enough to conclude that any hardware could be ok given the right software though

FNP7 @bkdo seems to have been taken seriously, see here. Worth a try.

I was able to speak with an accessibility rep & have my notes (diagnosis, specific issues, which devices cause problems, etc) forwarded to the engineering team. I'd definitely suggest calling and giving as much info as you can, you never know what'll happen.

upgraded to ios15 and felt the same. switching to dark mode and moving brightness to around 40% seems better

I actually do have an 8+ on 14.6 and another 8+ on 15.0, but I haven’t been able to see any noticeable differences in slow-mo recording or anything like that. There’s absolutely a difference in eye strain between them though, I just have no idea what changed 😐️

Clokwork I thought I was safe with my old device but apparently not.

I remember back in 2014 when I upgraded iOS to 7.1 on my iPhone 4S. Before I could use it for an hour without problem, after I could use it some seconds. If I used it 30 seconds my eyes was hurting so much, and I had to rest my eyes. I found some more users on the Apples forum with same device and iOS that had same problem. Some months later when I updated iOS I could use it again, and their was some more users on the Apple forum that reported the same.

I do understand that and I would love to help, but so far that was the only complaint about upgrade among the people who discuss eyestrain problems with me, so I can't propose them to join to A/B test. There's not enough tech for that.

Theoretically all the big changes in dimming algorithms should be visible on camera.

Clokwork

mike Thanks for that. It upsets me greatly that apple makes changes that they won't state anywhere in change logs. They only tell you the new features. I can only hope this gets fixed in a future update.

I briefly had my 6s (which is fine for me) on 15 and then reverted it to 14.8 when I still could. It didn't cause me eye strain, but the screen did look dimmer at all brightness levels (if that makes any sense) and had sort of a green/grey hue to it. This went away when I went back to 14.8. I haven't tried any versions of 15 past 15.0 because I won't be able to switch back at this point. I switched back to 14 because of bugs and performance issues, not eye strain. The 6s supports 15, but it doesn't run as well as 14 in general on that hardware.

On 15, what was normally a white background seemed fuzzier, more grey, and not static.
