iOS 27 Beta 4 ― Bug Fixes, Changes, and Improvements

[TheByteSmasher]

You can still inspect the real-time completeness using the Console app on a Mac. Connect your iPhone to a Mac and open the Console app on your Mac. In the sidebar, select your iPhone, start the log streaming, and type fetchPipelineCompleteness in the search bar. Quit and re-open the Settings app on your iPhone. You should see the following message:

fetchPipelineCompleteness: display=... days=... percent=…

The percentage is in decimal form, i.e. percent=0.90 means 90% done.

It started showing. I don’t have a Mac yet. Thanks for the advice though

Not seeing that here in the US on T-Mobile. Could be a carrier issue?

But your upload is abysmal?!?

Oh, and one more thing, where is the public beta?

But your upload is abysmal?!?

Oh, and one more thing, where is the public beta?

Upload on ANY carrier is abysmal - it’s simply a physics issue. Your phone is not capable of providing a strong enough uplink signal to a tower when it’s more then 500ft away.

Here are the median upload speed stats for the 3 major carriers in the US:

And here is my personal highest recorded upload speed, achieved on DB 2, with a giant cell tower in sight and 0 obstructions between:

Expecting more than 20-40mbps for upload speeds is irrational, and those speeds are not the fault of iOS 27 or this beta in general.

Damn, American 5G is so fast! You're lucky to get 50mb/s here in Europe. Or maybe Vodafone is just terrible.

5g speed on the freaking highway!

public beta 2 out

 

[dk001]

New issues:

iPhone Air - when launching an app from App Manager, getting infrequent pauses for 3-4 seconds before anything actually happens. No specific app but has occurred more frequently on apps that I need to log into like banking. New to this beta. Not seeing this on my iPad.

iPad Pro 11 M4 - have had YouTube (2x) and Prime Video (1x) both crash mid playing of a video. No warning, it just died. Has not occurred on the iPhone.

Anyone else missing all icons in Spotlight Search?

CarPlay has been good for me on this beta but the Safari reloads…

For me it’s the other way around - the wired CarPlay drops the connection, but Safari seems fine. 🤷🏻‍♂️

AirPlay lag when streaming music to an Airplay receiver, not always but it starts to breaks up / stutter

On my iPhone 14 I get 500 down and 100 up. Exactly those numbers. On an iPhone 17 much higher depending on location.

Not happy with the wired CarPlay dropouts in this beta, so going to flash it with the IPSW method and test it some more tomorrow.

 

[NoGood@Usernames]

Anyone else on a Verizon MVNO seeing a “Carrier Settings Update Available” message pop up when opening the About page that doesn’t actually update the carrier settings?

It pops up every time, and each time I hit “Update,” but nothing happens. I’m at Verizon 71.5.1

If it makes you feel better I've had several wireless CarPlay dropouts with B4.

I know I am not alone 😋, but I have noticed that my CarPlay dropouts got progressively worse as betas advanced. DB3 was the worst so far, so DB4 seemed better in comparison, but still bugged in that department. I have reinstalled DB4 now with IPSW, so will see if it helps. 🤞

We’re incredibly lucky to get UW/Millimeter Wave technology here which unlocks the gigabit+ speeds!

I’m sure the EU will catch up soon - you’re already ahead of us with most of the important stuff anyway 😉

Have you removed the iPhone from your vehicle's CarPlay list and vice-versa, then started over?

 

[Miles Fu]

I don't have any issue with wireless CarPlay on both DB3 and DB4

 

[AppleTester]

Anyone else having issues starting Guided Access from Control Center? Tapping the control doesn’t do anything for me.

 

[Dust-by-Monday]

Background sounds have stopped working for me in beta 4. I know they were working on all previous beta as I use this daily. Would anyone here be kind and check in their device if it’s not working for you either?
Id appreciate it!!

Same here man.

 

[ManuCH]

Keyboard still flickers for a second whenever Control Center is dismissed with keyboard showing. Happens everywhere throughout iOS.

Yes, I've had this since 26.0 and reported. They never fixed it and it's extremely annoying. Maybe if more people have this now they will give it more attention.

 

[ManuCH]

Mobile data speeds are considerably worse on this build than the last, at least for me in spain

Works fine here in Switzerland.

It never showed me a percentage or when the last update was. The indexing message just appeared, and then it disappeared a day and a half after installing beta 4 haha

Do you know how to reinstall using an ipsw? I tried doing it but every time I do so on my M1 Pro mac running Golden Gate, it just says the OS isn’t a valid OS.

Temporary (?) Workaround (for me, 17P): in Background Settings, toggle on “Use When Media Playing”.
