iPhone Pro Windows iTunes backup no longer works and iMac doesn’t recognize the device to backup.

But I do get to charge the device. How thoughtful.

Can’t do manual backups. Great.

New feature or bug?

I'm running iOS 26.3 Public release on an iPhone 12 Pro. This morning I plugged my iPhone into my Windows 11 computer and ran an iTunes backup. The backup worked fine without any issue. i also was able to charge the device as normal.

Hi guys, one question.
Currently got iOS 18.7.3 on my iPhone 15 Pro Max (86% battery), works flawlessly as of now.

Would you suggest upgrading to iOS 26.3?
My main concern are security fixes and the zero day vulnerabilities fixed with iOS 26.3.

As far as I understood, as of now, the main issues with iOS 26 have been fixed.
Seems to be still an awful user experience for many people due to some UI bugs, but apart from that, the most annoying blocker bugs (such as the camera one), should be gone by now.
Battery would be worse the first 2-3 days after the update due to indexing, but after that time frame and a few restarts, battery consumption should get back to normal.

Basically the tradeoff would be a getting all the "critical security patches", but a worse user experience and a few UI bugs.
Did I understand everything?
Or am I missing something?

P.S.
Obviously if there was a way to update my iPhone 15 Pro Max to iOS 18.7.5, I would jump onboard, but unfortunately it doesn't seem doable.

NO! Don‘t upgrade to 26.3!
I never had so many bugs (iPhone 17 PM)!

Yeah no luck here so far.

Doesn’t recognize no matter what I do.

Argh.

Anyone has this bug too?? (One of many bugs I have)

Oh, but at least the battery has improved again and lasts about 1 hour longer than under IOS 26.2.1 🤢

Starts to dim around 17 secs and locks at 26 secs for me on my 13 & 17 Pro.
I believe it has something to do with the attention aware feature and from what I can recall has been this way for a while now.

If the device is not being looked at actively, it locks a few seconds sooner to save battery. But then again, if the user is actively looking at it, it shouldn’t lock so the only scenario that setting works as expected is when the attention aware features are turned off.

Install MobileDeviceOnDemand.pkg & CoreTypes.pkg and reboot
forums.macrumors.com

iTunes software updates?

Thanks so much, so just open those two and that's it. So iTunes recognised the phone after the mobile device installer, what do I need the the CoreTypes one for, what does that one do? 17 went quick! Big big shame, hope they sort this on next .1

Did you hard reboot after? Sometimes the setting change doesn’t reflect until after.

EDIT: It’s working fine for me after disabling attention aware and a reboot. Dims around 20 secs and locks at 30 secs as expected.

Works not for me. 😥
 
It still looks like a dog's breakfast, especially the home page clock and the phone dialer which are surely bug afflicted on graphics, but otherwise seems not to be buggy.

Overall iOS 26.3 is running very well on the iPhone 17, and better than 26.2.1. No small annoying visual glitches here and there & performance is superb.
Battery life has also improved.

The only issue I’ve seen is the photos app closed itself while editing some photos. This hasn’t happened again after a hard reset.
 
On my 17 pro this update made me loose my last bit of hope. Are they only vibe coding everything now without proper reviews?
The jitter and stutter while scrolling across all apps and different parts of the system got way worse with 26.3 on my device. The worst is the list of control center elements that can be added. That one I tried on other devices with 26.3 and all have the exact same extreme stutter while scrolling there. So that‘s definitely just ****** software.
I‘m not that positive that they will be able to get their **** together in the future. They completely lost what made them excel, the work philosophy, organizational structures, the talents, the lead on many levels… just another big company with slow and ineffective processes now it seems…

Just wondering if anyone else is still getting the mail notification on their phone when wearing an Apple Watch?

I have them disabled on my watch (which works) but I get them on my phone now.

After a hard reboot, the iPhone no longer asks for a PIN here. Wow. 😂
(Good to know for thieves. Just check before whether 26.3 is played. 😎)

No way your iPhone didn’t ask for a passcode if it actually rebooted. It disables Face ID and asks for passcode even if you cancel the reboot after pressing the side button.

It don‘t ask me for my SIM PIN. 🤷‍♂️ Tested it 3 times. (After a normal restart, everything is ok.)

I haven’t had a SIM PIN set in years so don’t know anything about that. But if it used to ask but not doing now, be sure to file a feedback. Or file it anyway since it’s a security issue.
