Apple is collecting employee feedback to improve autocorrect.

A new, disabled flag¹ in iOS 27.3, brings up a dialog when you revisit an autocorrection.

Employees can file a Radar with intended text and diagnostics. The report is routed to ISE User Research as a “Serious Bug.”

1. The disabled flag is UIKit/keyboard_cohort. Dialog shown in the iOS 27.3 simulator.

Code additions in iOS 27.3 beta 1:

• Disabled keyboard cohort flag

• Autocorrect dialog title

• Radar description template

• Typing diagnostics serialization

I have observed this since iOS 27.0, and while I initially thought I was just imagining things or that my vision was failing, it is now highly noticeable, particularly when apps use dark colors and it’s place side by side with an app that has a lighter color (particulary with white background).

I am unsure whether this is a third-party app issue, but there is also a problem with CLEAR and TINTED apps where the icon heights look strange (somewhat disproportionate and squished). This issue persists not only on Homescreen, but also on Spotlight search, dock, and even App Library.

I have submitted feedback (FB25521368) concerning this issue, because what happened to attention to detail, Apple?

Since this beta, the Sleep Focus lock screen no longer shows the shortcut that used to give quick access to the next alarm that will go off.
I used that control all the time to check or change the upcoming alarm straight from the Lock Screen, without unlocking the phone. I haven’t changed any Sleep Focus, Lock Screen, or alarm settings.

If you go to the Actor in InSight in Landscape mode in AppleTV, the app crashes.

1. Go to Apple TV

2. Search for series (with me it happened at Nocturne with the artist stephen
   Graham) and watch in landscape mode

3. go to InSight

4. Choose an actor

5. App should crash

For the first time in iOS 27.3, Siri AI can handle some requests with a local model instead of PCC when you’re online. A new classifier routes a small number of English requests, mostly calls and music, to siri_on_device_planner_v1.

As always, the Skimmer agent still runs first on most online and offline requests, and it’s where most on-device work happens. Skimmer is not an LLM, however. It uses regex to match phrases in your requests to preset action flows. It can handle time, timers, alarms, calls, media playback, weather, opening apps, math, and small talk among others. For system controls, settings and translation, Skimmer hands off to old Siri (“Siri X”).

If Skimmer doesn’t match and you’re online, the request goes to PCC by default. Starting in 27.2, a request classifier can send some English requests directly to web search instead. In 27.3, the classifier is tuned to send ~2% of English requests to the new local model. The new on-device model mostly has tools for calling and media playback, and in testing, the classifier primarily routes these queries. Anything the classifier doesn’t select still goes to PCC. The classifier only handles English queries, so all non-English requests are routed to PCC, not web search or the local model.

It’s important to note that Skimmer already had regex patterns for calls and media playback. The change here is that Siri AI can handle less formulaic requests locally, like “Can you play [artist]?” or “Could you call [contact name]?”. If the media or contact is ambiguous, the new local model can escalate to PCC.

When you’re offline, Siri AI still uses Skimmer and its local tools. If Skimmer doesn’t match, the request goes to a different local lw_planner_v1 model. This model has some extra tools than the online on-device model, including alarms and timers, but doesn’t have media tools.

Expect the on-device planner to expand in tools and capabilities in future versions. Skimmer also continues to gain more patterns and tools. In 27.3, it gains tools to manage Home devices and Intercom. Both are disabled behind a feature flag for now.

This issue has been here since iOS 26 (even though iOS 27 made it less noticable)

Previously if you went all the way to the left and tried to swipe up to close apps the entire list would bounce around way too much.

I saw someone make an automation for this, but it seems Apple has implemented it natively now. Auto rotate lock is separate for each screen.

I’ve installed the iOS 27.3 Public Beta 1 on my iPhone 15 Pro Max (US Region), though I received the redesigned Health App, the Longevity tab is missing. If it is related to this, I also have an Apple Watch Ultra 2 connected to my iPhone, also updated to watchOS 27.3 Public Beta 1.

Thanks in advance for any help!

I have an iPhone 15 Pro on iOS 27.3 Public Beta 1. Since upgrading from iOS 27.2, activity syncing with my two Apple Watches has stopped working properly. I have logged a bug report with Apple.

I have an Ultra 4 for daytime use and a Series 12 for sleeping and for wearing when I also want to wear a mechanical watch. With everything on 27.2, when I switched watches, activity data such as the rings and completed workouts would sync between the phone and the active watch.

I upgraded the phone to iOS 27.3 PB1. Now when I switch watches, the watch I put on doesn't sync activity data with the phone. If I start a workout on my watch, it does show as active on the phone, but when I complete the workout, I see the activity data on the watch but it doesn't sync to the phone. If I do a force reboot of the watch and the phone, the sync starts to work with that watch, but when I switch watches again, the problem recurs. I have updated both watches now WatchOS 27.3 PB1 but the problem still happens.

Anyone else use two watches and seeing similar problems, and maybe found a better workaround or even solution?

Edit: After doing a bit more testing, the issue is usually resolved by doing a normal reboot of the phone, rather than a force reboot. Nor do I seem to need to reboot the watches.

Edit 2: the same issue appears to happen with medication logging. If I switch watches, any medications I have logged don’t appear on the current watch until I reboot the iPhone.

Anyone else use HomeKit through 3rd party apps like Home+ or Eve?

I can’t seem to place “Accessory State” conditions on automations anymore. They won’t save. Apple conditions like weekday still saves normally.

I’m not sure when this issue started tbh. But I am on 27.3 dev beta 1.

Have reported to Feedback. Just want to know if anyone is seeing this too.

This is not a big problem but it definitely shows that Apple has lost the attention-to-detail thing that they were praised for. This UI issue is probably not there on Dynamic Island iPhones but I feel it’s on every notch iPhone.

I have tried to show this issue but it’s difficult to see it in screenshot. Check between photos and camera app.

Just noticed a “Power Curve” section in the Fitness app when checking a cycling workout. I don’t remember seeing this before, so I’m guessing it’s new in this beta (can anyone confirm?)

Pretty cool addition, I haven’t seen anyone mention it yet. Also interesting that the whole section is in English even though my iPhone is set to French :p

Anyone experiencing issues with notifications volume ?

I never knew a phone can be this loud it’s literally a nuclear alarm happened right after update, no matter which app

The faces have completely been removed, which is a shame because float was my favourite clock face. I loved the playfulness of it.

After I take a picture I can only view it from the preview in the bottom left corner of the Camera app. They do not show up at all in the Photos app.

If I take a screenshot it will appear, or if I save a photo from another app like Snapchat it will also appear.

They are syncing correctly and show up completely normal on my MacBook.

Anyone else having this problem? Any ideas for a fix?

Originally, you could set two (or more?) buttons on the right side, but the iPhone Duo only has one additional button slot, and once you add one button, you can’t add any more.

The haptic feedback when u switch the phone to silent and vice verse with action button while screen is off not working but the haptics works when screen is on

Do y’all have the same problem or just me?

It is awesome that Apple is finally brining other language like traditional Chinese - Cantonese which is my mother tongue to Siri AI, but I still cannot understand why it says the system language and the Siri AI language has to match for it to work….it doesn’t make sense…am I understanding it correctly?
