Failed upgrade, jailbreak or hardware problem can lead to iPhone. When upgrading to Windows 11 from Windows 10 or when installing an update to Windows 11.
Using Feedback Assistant
You can submit feedback to Apple using the native Feedback Assistant app on iPhone, iPad, and Mac, or the Feedback Assistant website. When you submit feedback, you’ll receive a Feedback ID to track the submission within the app or on the website.
Feedback Assistant App
The Feedback Assistant app for iOS and macOS includes several convenient features:
Automatic on-device diagnostics. There's no need to manually collect and attach a sysdiagnose for each bug. With your permission, Feedback Assistant can also execute area-specific diagnostics, allowing you to send information beyond the scope of a sysdiagnose.
Remote filing. With Feedback Assistant on iOS, you can file reports about your connected Apple TV, HomePod, or Apple Watch, with support for collecting device diagnostics directly on those devices.
More detailed forms. You can provide detailed information through specific, conditional questions while still enjoying a concise filing experience.
More feedback statuses. You’ll have a better understanding of the statuses of most feedback you’ve filed.
Installing the App
The app requires iOS 12.4 or later, iPadOS 13 or later, or macOS Catalina or later. On beta versions of iOS and iPadOS, the app is available by default on the home screen. On publicly released versions of iOS and iPadOS, you can enable the app by installing a beta profile. All versions of macOS include the app in /System/Library/CoreServices/Applications, and it can be launched with Spotlight or the URL scheme applefeedback://. When enrolling a macOS system in beta builds with the Beta Access Utility, the app is added to the Dock and aliased in /Utilities.
Attaching Screenshots, Profiles, and Logs
Since the Feedback Assistant app automatically attaches a sysdiagnose for each bug, we recommend submitting bug reports directly from the app on your iOS device or Mac. Alternatively, you can use the website to manually upload relevant files as well as folders as compressed file archives. To compress a folder on Mac, right-click or Control-click on the folder and choose Compress from the menu that appears.
Be sure to include any necessary profiles and logs to expedite our investigation process. A Mac System Information Report is required for crashes or kernel panics, reports against hardware, and issues with printing. After reviewing your report we may ask for additional files, which you can attach after submission.
Sharing Feedback with Your Team
You can automatically view and respond to feedback filed by your team members if you're part of an organization in the Apple Developer Program, the Apple Developer Enterprise Program, Apple School Manager, or Apple Business Manager. Simply sign in to Feedback Assistant with the same credentials. Current assignees and the roles listed below are able to re-assign and close feedback, and download attachments. These roles can also remove feedback from the team inbox.
Program Roles: Account Holder, Admin, App Manager
Apple School Manager and Apple Business Manager Roles: Site Manager, Admin
In addition to your team inbox, you'll also have a personal inbox for separate submissions. You can move feedback into your team inbox if you wish.
This feature in the Feedback Assistant app requires iOS 14, iPadOS 14, or macOS Big Sur.
Viewing Older Bug Reports
While Apple Bug Reporter is no longer available, you can still track your older bug reports in Feedback Assistant using their associated Problem IDs. Bugs are displayed in Feedback Assistant, with the original text and attached files included. The Problem ID is appended to the title and any dialogue is displayed natively in Feedback Assistant as messages from Apple and replies from you, complete with timestamps.
As part of our commitment to privacy and to address the European Union’s General Data Protection Regulation (GDPR), we’ve removed developer data from certain bug reports as of late fall of 2018.
Data was removed from inactive bugs. Bugs that have been closed for at least five years, have not been updated for 60 days, and are not a duplicate of another bug had developer data removed. Developer-originated sysdiagnoses and related attachments were deleted, and any reference to the bug originator were redacted. In addition, these bugs are no longer displayed.
Duplicate bugs will remain available for a limited time. If a bug is marked as a duplicate, developer data will be removed once the original bug has been closed for five years and has not been updated for 60 days. Until then, you can continue to follow the state of the original bug until it’s closed, and engineering can still reach out to you until the bug is resolved.
You should file a bug report if you continue to experience an issue with Apple software or services. For support-related issues, contact us.
Program Support. For help with your developer account such as changing your name, changing your address, or inviting people to your development team, contact Apple Developer Support.
Technical Support. If you are an Apple Developer Program member, you can request code-level support. Submit a Technical Support Incident (TSI) after filing the bug report. Your incident will be assigned to a developer technical support engineer who can provide a workaround if one is available. For up-and-running support, contact AppleCare.
Submitting General Feedback
If you’re not a developer and would like to provide feedback on public beta versions of Apple software, you can use Feedback Assistant as a member of the Apple Beta Software Program.
A new iPhone bug has come to light that breaks your iPhone's wireless functionality by merely connecting to a specific WiFi hotspot.
Once triggered, the bug would render your iPhone unable to establish a WiFi connection, even if it is rebooted or the WiFi hotspot is renamed.
A bug like this could be exploited by malicious actors planting rogue WiFi hotspots in popular areas to bork iPhone devices connecting to them.
This WiFi hotspot will bork your iPhone
'link' List Of Known Iphone Bugs 2020
This week, reverse engineer Carl Schou ran into an issue when connecting to his personal WiFi hotspot named:
On connecting to the hotspot, his iPhone's WiFi would be disabled, and every time he tried to enable it again, it would quickly turn off, even if he restarted the device or the hotspot name was changed:
'After joining my personal WiFi with the SSID '%p%s%s%s%s%n', my iPhone permanently disabled it’s WiFi functionality. Neither rebooting nor changing SSID fixes it :~),' tweeted Schou.
Schou told BleepingComputer that his experiment worked successfully on an iPhone XS, running iOS version 14.4.2.
Tests conducted by BleepingComputer on an iPhone running iOS 14.6 confirm an iPhone's wireless functionality would break after connecting to the strangely named wireless network.
In multiple tests attempting to connect to this strange SSID, our Wi-Fi settings would begin to function erratically, but all led to the same behavior - the breaking of our iPhone's wireless connectivity.
In some tests, connecting to the SSID would fail, but we could no longer access our regular wireless network.
Other tests led to the behavior described by Schou, where the iPhones Wi-Fi setting would be disabled, and we could no longer enable it again, as shown below.
The only way to fix our iPhone's broken Wi-Fi feature was to reset the device's iPhone network settings, which we describe how to do at the end of the article.
A bug like this is serious, considering malicious actors could plant rogue WiFi hotspots (needing no password) in popular areas to bork iPhone devices that connect to them.
According to users, the issue is unique to iPhones and does not appear to be reproducible on Android devices:
So I haven't done any homework on this bug / wouldn't even really know where to look but i'm guessing this is just an ios bug??

Likely a string formatting vulnerability
Other security researchers who saw Schou's tweet and analyzed the crash report believe that an input parsing issue likely causes this bug.
When a string with '%' signs exists in WiFi hotspot names, iOS may be mistakenly interpreting the letters following '%' as string-format specifiers when they are not.
In C and C-style languages, string format specifiers have a special meaning and are processed by the language compiler as a variable name or a command rather than just text.
For example, the following printf command does not actually print the '%n' character but stores the number of characters (10) preceding %n into the variable 'c.'
The '%n' is merely a format specifier and not an actual text string. As such, the output of the following line will simply be 'geeks for geeks,' with no mention of '%n.'

Some users have claimed previously inserting the relatively innocuous '%x' format specifiers in their WiFi SSID to avoid causing major issues for unsuspecting WiFi users.
When asked what was his motivation to name his WiFi hotspot with the funky string specifiers, the reverse engineer said:
'All my devices are named after format strings to f*** with poorly developed devices,' Schou told BleepingComputer.
How to rescue your iPhone from this WiFi bug?
Although restarting your iPhone won't fix the issue, this bug is not permanent and can be fixed without resetting your entire device.
Instead, you can follow these simple steps to reset your iOS network settings to resolve the issue:
- Go to Settings on your iPhone, select General.
- Under General select Reset.
- You will now be at the Reset screen, where you can reset various features of iOS or the device itself.
At this screen, select the 'Reset Network Settings' option and confirm you would like to continue when asked.
- The device will now restart and reset all of your network settings back to factory default. Once it has restarted, enter your passcode, and you can reconfigure your Wi-Fi settings again.
