Is anyone having issues with YouTube player in Safari?
Buttons often disappear, commands lag, it freezes. I only noticed it in the past few days and don't use any other media sites to know if it's YT exclusive.

All albums are appearing gradually, one after the other. It takes time to load.
The same goes for recents in the phone app, sometimes it takes a while for the people I've called to show up.

Ah ok, now I see it.
Tried it on my 14 testdevice and 16 and 16 pro, but can't reproduce it. The 14 is a very clean testdevice so not really representative of how a regular user would use their phone.

Is your phone storage filled to the brim? I know that (and many other things) can affect performance.

50gb free storage, also 2 of my fridends with 17pro have the same bug
 
Have you guys been experiencing constant app reloading since iOS 26.0? I still notice it every day, even on iOS 26.3. I'm using an iPhone 16 Pro Max.

For example, I open Instagram or WhatsApp when I wake up, then I use other apps. Suddenly, for no apparent reason, when I reopen WhatsApp, it reloads as if it’s the first time I’m opening it. After that, other apps show the same behavior.

Sorry if this has already been posted many times and I couldn’t find the answer, but it’s really annoying. I never had this issue before iOS 26, and I’m not willing to do a full restore on my iPhone just to try to fix it.

Not that I have noticed. Using Whatsapp but not that much so might have missed the reloading bit. Don't use insta tho. so can't really tell.
Will have a lookout for it and report back if I notice it. 16 Pro

I turned off autocorrect a looong time ago, it wasn't worth it. Have yall tried resetting your keyboards?

Yep. Even reset device and set up manually from scratch - no backup - couple betas back. Nothing has helped. The level of screwy spelling/grammar varies per beta but it has never been good.
 
New one….
I do not backup Messages to the iCloud.
However, starting this morning, I am getting messages popping up (4 so far) that are old. I get the “DING” and there is a message, unread. These were all previously deleted. Latest was my Mint Mobile renewal dated Jan 17. The others are from Dec 2025.
btw - these new previously deleted messages that were resurrected also post in my Notifications. That’s how I found them.
 
Honestly, I’ve never really had any issues after software updates before.
But this time, it feels like I’m dealing with every single bug possible. 🤣

Does this happen when you already have the app open and are going into it or do I have to "kill" the app and then are open it to see it?
I can see a tiny lag on one of my phones if I kill the app, but its not as bad as yours.
 
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?

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.
