So who is going to be the first to ask?

 

[Cobold]

So who is going to be the first to ask?

Is Safari more intelligent? 🤔

 

[Banglazed]

IPSW is up

 

[Reeneman]

Doing a short internet best of here:

How’s battery life? Safari performance?
How are the temps? Overheating?
Is Liquid Glass finally removed??
Another trainwreck of release?
Still the buggiest iOS release ever?

 

[jpsmith76]

As long as Siri stops repeatedly reading my texts, that’s all I’m hoping for with Beta2

 

[TheBeverage]

Tim Cook personally informed me they removed Liquid Glass for this update.

 

[HouseLannister]

So who is going to be the first to ask?

Battery life is awful.
Safari seems snappier.
Siri is still dumb.

Does that cover it?

 

[LutzRFrank]

shall I really risk to face a fifth restore cycle within a week?

Ok, getting used to it - the last (including iCloud backup) took 3.5 hours to complete ...

 

[adrianlondon]

Quick! Update before the release notes are available!

It makes it all more exciting.

they are out now, but as expected a 1 to 1 copy of the previous one

 

[Simacca]

Just installed on my 16 pro and it froze on the lock screen. Just had to hard restart to get it going again.

My home screen stutters have been fixed, thankfully.

I too had the data bug issue and yesterday was my fourth restore prior to this update I was already ballooning back up to 70gb data. Post update I’m at 13 gb and it hasn’t changed. So.. maybe?

 

[GetBehindMyBarrier]

Apple to Android RCS E2EE is enabled in Beta 2.

 

[Hamsterhjulet]

Search bar is still placed at the top in App Store but not in any other app. If it’s intentional why is it only for App Store?

Do you mean this?

I think is some kind of regression from the new profile distribution (with the Updates tab). Maybe they had some weird bug and had to disable the liquid search textfield.

on my 14 PM, which didn't explode so fast, but hat already>40GB it is down to 1GB after update

 

[Knowlege Bomb]

Lots of CarPlay issues in beta 1 so hoping that has been addressed.

Also a fix for scrolling in Mail would be greatly appreciated.

 

[FILIPSN007]

Let me know after three days.

 

[eastpointvet]

seems cool so far I still hate the extra steps to update apps though as I would normally do this several times a day and know its an extra step that I hate

 

[LutzRFrank]

Are Home Screen widgets suddenly centered?

 

[thelion7]

26.3 RC screwed my m3 iPad Air up and 26.4 beta 1 made no difference.

It says it’s charging when it’s been unplugged for hours and the battery is diabolical.

Can’t even DFU restore on my Mac mini.

Basically waiting for 26.4 beta 2 public beta so I can switch to that from Dev beta.

Of If I can’t restore after that, then its a trip to the Apple Store.

 

[nortonandreev]

Didn’t expect it this week.

This bug is back…
