dockkit anomolies -- anyone else seen these?
I have two Dockkit anomolies to report. Hoping a DTS person has seen these and/or can comment. First, my setup: I am controlling the accessory by making repeated calls to set the angular velocity. And the first thing I do is make a call dockManager.setSystemTrackingEnabled(false) because I'm doing my own tracking. I would note that I tried calling track() on my own, with a bunch of observation rectangles (or even just one) but it didn't work well, even though I was calling at the correct rate. Instead, I measure the angular deviation to where I wish my camera was pointed, and set the angular velocity proportional to the error. First issue: in normal operation, the green tracking light is on, on the hardware (the Instaflow Pro 360 motorized dock). Squeezing the trigger toggles the green light on/off; only when the light is on will the dock accept my calls to set the angular velocity. Fine. But sometimes squeezing the trigger won't reactivate the green light. In this case, the ONLY thing that seems to work is switching to the Instaflow Pro 360 app, and activating the camera. Immediately the green light turns on, and I'm good (and can return to my own app, with the green light still on). So what hidden API call does Instaflow have, that I don't that can make this happen? Sure, it's their own app, but I imagine they don't have access to calls I don't, so how does their app manage to get the green light back on? It doesn't always happen. Would love to know how to snap out of this. Second issue: While I usually use rectangle from running the vision system to guide my camera position, sometimes I left the user directly control the angular "yaw" velocity (rotation around the vertical axis) directly (by issuing commands over the network). Sometimes, when the user sets a non-zero velocity, when they set a zero velocity a short time later, the camera doesn't immedately respond and stop. (It's not a network issue. I can verify the API sends a call to set the angular velocity to zero, and the camera keeps rotating for a good fraction of a second.) Most times the camera stops immediately, but sometimes it doesn't. Oddly, I never see this issue when letting the user set the angular velocity in the "pitch up/down" axis. Just the yaw axis. Anybody else seen this? I feel like it wasn't a problem till I got to iOS18 but I won't swear to it. Any advice/assistance/discussion greatly appreciated.

Monitor flickering after MacOS Sonoma update
After update to MacOS Sonoma 14.7.1 (23H222) my external monitor immediately started to flicker (noticeable even on 100Hz refresh rate). During the update the external monitor was connected to the laptop. Flickering persist on personal Windows laptop too. Tried to connect/disconnect current cables, flickering persists. Tried to switch to another cable Display port to HDMI, flickering persists. Monitor now is basically unusable, the update damaged it.

iPhone Camera issue
I recently updated both my phones iPhone 14 Pro Max and iPhone 16 Pro Max on iOS 18.1, and after update when I open camera and go to SLO-MO the screen starts flickering, even though after recoding when I play the video. Video is playing the same with the flickering screen. is it iOS update issue or something else.

Torch Strobe not working in light (ambient light) environments on iOS 18.1
As of iOS 18.1 being released we are having issues with our users experiencing issues with our app that relies on strobing the device torch. We have narrowed this down to being caused on devices with adaptive true-tone flash and have submitted a radar: FB15787160. The issue seems to be caused by ambient light levels. If run in a dark room, the torch strobes exactly as effectively as in previous iOS versions, if run in a light room, or outdoors, or near a window, the strobe will run for ~1s and then the torch will get stuck on for half a second or so (less frequently it gets stuck off) and then it will strobe again for ~1s and this behaviour repeats indefinitely. If we go to a darker environment, and background and then foreground the app (this is required) the issue is resolved, until moving to an area with higher ambient light levels again. We have done a lot of debugging, and also discovered that turning off "Auto-Brightness" from Settings -> Accessibility -> Display & Text Size resolves the issue. We have also viewed logs from Console.app at the time of the issue occurring and it seems to be that there are quite sporadic ambient light level readings at the time at which the issue occurs. The light readings transition from ~100 Lux to ~8000 Lux at the point that the issue starts occurring (seemingly caused by the rear sensor being affected by the torch). With "Auto-Brightness" turned off, it seems these readings stay at lower levels. This is rendering the primary use case of our app essentially useless, would be great to get to the bottom of it! We can't even really detect it in-app as I believe using SensorKit is restricted to research applications and requires a review process with Apple before accessing? Edit: It's worth noting this is also affecting other apps with strobe functionality in the exact same way

Hello Apple Support Team
Hello Apple Support Team, I'm experiencing an issue with my iPhone 15 Pro. Although the battery health shows 100%, the phone shuts down unexpectedly at various charge levels, sometimes as high as 70% or even 40%. My iPhone is currently on iOS 18.2 beta 2, but this issue began with iOS 18.2 beta 1. I’ve tried multiple troubleshooting steps: Formatted the iPhone Performed a force reboot Upgraded and then downgraded the software Unfortunately, none of these solutions resolved the problem. The panic report doesn’t appear to show anything conclusive. I'm attaching the panic report for further analysis, as I’m unsure if this is a software bug related to the beta or a hardware issue. Thank you for your assistance.

iPhone 14 Plus Rear Camera Issues After iOS 18 Update - Green Tint and Limited Functionality
Hi everyone, I’m experiencing a frustrating issue with my iPhone 14 Plus after updating to iOS 18. Ever since the update, the rear camera has become almost completely unusable, while the front camera still works fine. Here’s a breakdown of the problems: Camera app shows a black screen - When I open the Camera app and switch to the rear camera, the screen is just black with no visibility of any objects or scenes. Limited photo capability - I can only take photos using the 0.5x zoom, and even then, the results are abnormal. Every photo taken with the rear camera has a strange green light at the lower bottom, just like the one in the attached photo. Unavailable features - All rear camera features, like video, panorama, portrait, and cinematic mode, don’t work at all. It’s like the camera is only partially functional. “Clips” app works normally - Interestingly, the “Clips” app is still able to take videos with the rear camera, so it seems like the camera hardware itself is fine. This issue seems specific to the Camera app and any functions within it. I waited for two updates—iOS 18.0.1 and 18.1—hoping Apple would resolve this, but unfortunately, these updates haven’t fixed the issue. I even went to the Apple Service Centre, but since my device is out of warranty, they told me that if I want it fixed, I’d have to pay MYR905 (around USD$200+) to replace the rear camera. They diagnosed it as a hardware issue, but I can’t help but feel it’s related to the iOS 18 update, as the problem started right after updating. I’ve always taken good care of my device, so this doesn’t seem to be due to any physical damage or misuse on my part. Is anyone else experiencing something similar? Could this be a software bug in iOS 18? Any help or insights would be greatly appreciated. Thanks!

iPad external display inconsistency
iPadOS behavior with secondary displays is inconsistent. Firstly, Apple has not published what is the lower limit for supporting the extended display in non-mirrored mode. In iPadOS 16.1 beta even lower resolutions were supported, but it looks like the monitor must now support at least Full HD (1920x1080). Otherwise there will only be the possibility for mirroring the iPad screen and the Arrangement menu will not be visible in iPadOS Settings. This is the case with all iPadOS versions from 16.1 to 18.2 (beta). Secondly, even on monitors that do support Full HD or better resolution, iPadOS may still choose to only support mirroring with a strange resolution such as 1280x1024 even though 1920x1080 would be available. I have tested with various iPad Pro 11" models from gen 1 to gen 4, various USB-C adapters, and cables. Extended display does work properly with certain monitors, but the above issues still exist on others. I have filed feedbacks FB13576000 (Feb '24) and FB11467189 (Sep '22) on this bug. On the Support Community Forums there are a lot of users mentioning the same issues.

iOS: Can third party app see USB descriptors?
We have a USB dongle that would like to connect to the iPhone for power (using USB-C). Since it is not MFi, we will then use bluetooth for communication between the dongle and an app. When doing bluetooth pairing between the dongle and iPhone, it would be ideal to only see the dongle that is plugged into the iPhone listed in the app. This is to avoid connecting to other dongles that may be in the area. We think this could be possible using USB descriptors. We assume the iPhone can read the USB descriptors for non-MFi dongles. Our question is, can our app see the USB-descriptors of the dongle? Is iOS able to pass that info to the app? Then, we could have a unique USB descriptor for each dongle and the app could only list bluetooth devices with that descriptor (effectively filtering out any other dongles in the area). Any help and/or feedback is greatly appreciated :)

iPhone/iPad lose Data connection when using USB-C to USB-C cables after reboot on ARM Macs
I've noticed an issue when using an iPhone or iPad that uses a USB-C port (such as the iPhone 15 Pro or iPad Pro 12.9" 6th generation) and a USB-C to USB-C cable on ARM Macs (such as the M2 Mini). After rebooting the Mac, the iOS device is no longer recognized despite the iOS device continuing to charge. I can temporarily resolve the issue by reseating the USB-C cable, which allows the device to be recognized again by applications like Finder. However, this isn't a practical solution due to the number of M2 Minis we have (each with an attached iPhone for testing) and the Mini's frequent automatic reboots throughout the day. Using a USB-A to USB-C cable (with USB-A connected to the Mac Mini) seems to avoid this problem altogether, as the iOS device remains consistently recognized after a reboot. As the title suggests, this issue appears to be specific to ARM-based Macs. We've encountered it on both the M2 Mini and a 2021 Macbook Pro with the M1 Max chip. Interestingly, we haven't been able to reproduce this behavior on Intel-based Macs (tested on an 8,1 Mac Mini and a 2019 16" Macbook), where the iOS devices remain connected after a reboot when using a USB-C to USB-C cable. Here are some additional details: iOS Devices & Versions: iPhone 15 Pro: Issue persists on both iOS 17.1 and iOS 18.0.1 iPad Pro 12.9" (6th generation): Issue persists on both iPadOS 17.6.1 and iPadOS 18.0.1 Cables: Apple's 60W USB-C Charge Cable (USB 2.0): Issue occurs Generic/Third-party USB-C cable (USB 3): Issue occurs

AVCaptureControl
I added some AVCaptureControl, then removed all of it. The phenomenon is that AVCaptureSession controls are 0 in number, but the keys can still display the previous AvcaptureControls guard(_session.supportsControls) else return; for (AVCaptureControl *control in _session.controls) { [_session removeControl:control]; } @weakify(self); if (self.captureControl.zoom) { if (self.zoomScaleControl) { self.zoomScaleControl.enabled = false; [_session removeControl:self.zoomScaleControl]; } AVCaptureSlider *zoomSlider = [self.captureControl.zoom fetchCaptureSlider]; [zoomSlider setActionQueue:dispatch_get_main_queue() action:^(float zoomFactor) { @strongify(self); if ([self.dataOutputDelegate respondsToSelector:@selector(videoCaptureSession:tryChangeZoomScale:)]) { [self.dataOutputDelegate videoCaptureSession:self tryChangeZoomScale:zoomFactor]; } }]; self.zoomScaleControl = zoomSlider; } else { self.zoomScaleControl = nil; } if (self.captureControl.exposure) { if (self.exposureBiasControl) { self.exposureBiasControl.enabled = false; [_session removeControl:self.exposureBiasControl]; } AVCaptureSlider *exposureSlider = [self.captureControl.exposure fetchCaptureSlider]; [exposureSlider setActionQueue:dispatch_get_main_queue() action:^(float bias) { @strongify(self); if ([self.dataOutputDelegate respondsToSelector:@selector(videoCaptureSession:tryChangeExposureBias:)]) { [self.dataOutputDelegate videoCaptureSession:self tryChangeExposureBias:bias]; } }]; self.exposureBiasControl = exposureSlider; } else { self.exposureBiasControl = nil; } if (self.captureControl.len) { if (self.lenControl) { self.lenControl.enabled = false; [_session removeControl:self.lenControl]; } ORLenCaptureControlCustomModel *len = self.captureControl.len; AVCaptureIndexPicker *picker = [len fetchCaptureSlider]; [picker setActionQueue:dispatch_get_main_queue() action:^(NSInteger selectedIndex) { @strongify(self); if ([self.dataOutputDelegate respondsToSelector:@selector(videoCaptureSession:didChangeLenIndex:datas:)]) { [self.dataOutputDelegate videoCaptureSession:self didChangeLenIndex:selectedIndex datas:self.captureControl.len.indexDatas]; } }]; self.lenControl = picker; } else { self.lenControl = nil; } if ([_session canAddControl:self.zoomScaleControl]) { [_session addControl:self.zoomScaleControl]; } else { self.zoomScaleControl = nil; } if ([_session canAddControl:self.lenControl]) { [_session addControl:self.lenControl]; } else { self.lenControl = nil; } if ([_session canAddControl:self.exposureBiasControl]) { [_session addControl:self.exposureBiasControl]; } else { self.exposureBiasControl = nil; } [_session setControlsDelegate:self queue:GetCaptureControlQueue()];

Commissioning Matter Thread Device without Hub
I have been looking at the new feature in iOS 18 where it is possible to pair Matter accessories without a hub. Using the Home app I can successfully commission and control a Matter Thread Light Bulb directly (without a home hub in the network). I have an iPhone 15 Pro which includes the thread hardware. I then tried to commission the same device in my own app using the MatterSupport framework. In this case the same user interface is displayed as when using the Home App but an error is displayed - "Thread Border Router Required." Is it also possible to connect directly to a thread Matter device when using MatterSupport or does this only work when using the Home app?
