Small update for my iPhone 17.

 

[AnInanimateCarbonRod]

Wi-Fi 7 on N1 chips is still broken in this release. Guess we're waiting for 26.5 for that one.

Is this a broad known bug or is it something that you experience personally?

 

[Maloney~888]

Yay 🙌🏻 downloading/installing now.

 

[James6s]

Installed and all good so far, seems to have fixed some annoying delays to load some apps content that I was experiencing on 26.4.1.

 

[jacenskylo]

My screenshot to PDF feature is still not working on my work tablets. I reached out to apple support prior to the update and they said others were having similar problems. I guess I’ll have to wait to IPados 26.5 hopefully. In the meantime I’ll just have to utilize workarounds

 

[gardiboy]

Is the swipe up and between pages animation. stutter fixed?

What do you mean? Wi-Fi 7 works on my iPhone 17 Pro Max. What are you experiencing and with what type of router?

 

[ValerieDurden]

Of course not.

 

[AnInanimateCarbonRod]

Both. Some examples from reddit, but I know there's been posts here about it as well:

https://www.reddit.com/r/Ubiquiti/comments/1s3h8xo/iphone_17_pro_max_not_connecting_to_wifi_7

https://www.reddit.com/r/iphone/comments/1s3jldz/any_iphone_17_users_with_n1_chip_able_to_connect

https://www.reddit.com/r/Ubiquiti/comments/1s393k4/pro_xg_no_wifi_7_with_ios_264

It's been fixed since 26.5 beta 1 apparently, but I was hoping Apple would backport it to these point releases as well.

 

[Newton1701]

My 17 Pro has been working fine on my Netgear Orbi WiFi 7 network on all iterations of iOS 26

 

[Katopaul05]

WiFi constantly disconnecting since 26.4. Seems to be fixed with 26.4.2. Thankfully. Unbelievably annoying. 17 Pro Max 1TB

Does anybody know if this is safe to install with Apple Devices?

 

[ValerieDurden]

Samsung devices only unfortunately.

If you change your PC, it probably will hehe

 

[rgarita]

Does anybody know if this is safe to install with Apple Devices?

yes it is, official final version

 

[Aethelwulf]

Waiting to install this evening. Please, all gods, let it fix the @#$%^#$ "call failed" bug on my iPhone 16+..

 

[s2mike]

Tried to record video at a concert tonight and zooming in/out in the Camera app froze / locked up multiple times. Another awesome update from a trillion-dollar company.

 

[Reeneman]

I think so. Samsung devices might have issues installing the updates, same goes for Oppo and others. But for Apple iPhones and IPads it should be safe to install.

Try to restart your device

 

[James6s]

All good this morning on iPhone 17, done my usual hard reset the day following a software update.

Battery seems to be draining slower with my same usage.

Hi everyone,

I think I’ve stumbled upon a weird UI glitch in the native photos app on the latest iOS 26.4.2 build. I'm seeing it on my iPhone 17 Pro Max and my iPad Pro, so it seems to be a software issue.
Basically, the video player in the photos app is totally broken. There are no timestamps (start/end times are missing) and the progress bar looks fragmented with weird blue and gray blocks instead of a clean line. Even the play button and other icons look misaligned or partially cut off.

The strange thing is that the videos themselves are perfectly fine. If I send them via WhatsApp or open them in the files app, they look and play normally.
It looks like a specific rendering bug for the standard playback view on larger displays. Has anyone else noticed this? I first saw it after importing a large library, but it also happens with freshly recorded videos.
(For those wondering: I've already tried a standard restart and a forced restart (hard reset) on both devices, but the issue persists. It didn't change anything.)

Would love to hear if others can reproduce this!

So did the update hour ago and when it came to the apple logo and progress bar it turned off and hasn’t come back on since …

I would plug into iTunes and see if you get any response. The best would be to DFU back to your last backup. But if you can't get any response from the device, you may need to reach out to Apple support for help.
