Apple cares about the privacy and security of its users. It takes this matter very seriously. That is why it provides us all the time with many protection features that prevent intruders, thieves and even agencies. Law enforcement From accessing user data on IPhoneThe latest feature to enhance privacy and security is a passcode that Apple recently launched, which prevents anyone from accessing what is inside your iPhone, even if they were able to unlock the device previously.
Secret code to restart iPhone
With the iOS 18.1 update, Apple has introduced a secret feature to its users known as “Inactivity Reboot” or “Reboot in Inactivity” which works in certain situations. Including, if the screen has not been unlocked for some time or the device has not been connected to the cellular network for a whole day. Once this code is activated, the iPhone will automatically restart. After that, the device becomes more secure and it is almost impossible for a hacker to unlock your phone again.
Data encryption mechanism in iOS
Before we get into the secret code, let’s first understand how data encryption works on the iPhone. Your iPhone can be said to be in one of two states, either before first unlock “BFU” or after first unlock “AFU”.
Everything inside the iPhone remains securely encrypted until the moment the user enters the screen lock passcode and unlocks the device for the first time, at which point the iPhone is in a “Before First Unlock” (BFU) state.
When the passcode is entered and the device is unlocked, the operating system starts generating a set of keys required to decrypt files on the iPhone. This way, everything inside your device is fully encrypted and cannot be accessed until you enter the passcode.
When the device is restarted and the correct passcode is entered, iOS goes from BFU to AFU (After First Unlock) state, which decrypts the data on the device and activates features like Touch ID or Face ID. That’s why individuals who are being questioned by law enforcement agencies are advised to restart their devices and then keep them locked. The system temporarily turns off biometric authentication and keeps the data encrypted, making it nearly impossible to try to unlock the iPhone or even extract files inside it.
The story of discovering the code!
A 404 Media report claims that forensic officers and experts have discovered that iPhones that have been stored for forensic examination due to their connection to certain cases are somehow rebooting themselves, returning the devices to a state that makes them very difficult to unlock. The report notes that iPhones that are rebooted in a BFU state send wireless signals to other nearby iPhones that are in an AFU state, telling them to automatically reboot themselves. But the strangest thing in the report is that one of the iPhones was inside Faraday cage (A box used to isolate its interior from any electrical or electromagnetic influences) and therefore it was supposed to be unaffected by Apple's new code. But the exact opposite happened. The device automatically rebooted.
Finally, Apple has not officially spoken about the matter. However, we must take into account the possibilities that may lead to the device restarting for no reason. It can be said that there are two possibilities and no third. The first is a glitch, as some devices running iOS 18 suffered from a bug that caused them to restart randomly throughout the day. The problem was fixed in the iOS 18.1 update. As for the second possibility, Apple introduced a hidden feature in the new update to secure the privacy of its users.

شكرا ميمي للايضاح 😘🌹
يشكر الاخ عبدالله محمد احمد طرح هذا السؤال وهو ماكان بخاطري واود طرحه ووجدته منه مشكوراً ويشكر على الاجابة من الفريق الفني والدعم الجميل المهندس محسن ابو النور 🫶🏼
How to activate this feature, the article is a bit vague
Hi Abdulrahman 🙋♂️, I apologize if the article was not clear to you. The “Restart in Inactivity” feature is automatically enabled with the iOS 18.1 update, so you do not need to take any steps to activate it 📱. Once the update is installed, your iPhone will restart itself in certain situations, such as not unlocking the screen for a while or not connecting to the cellular network for a whole day. This feature is added to a range of other features that Apple always seeks to ensure user privacy and security. I hope this is clear! 🍏🔐
I think this is a problem.
Apple will release a quick update 18 points one point one
To solve this problem quickly
The update will not take long, it will come quickly to solve this problem
But I have a question, does this problem apply to all iPhone models?
I have an iPhone and I don't have the problem

Hello world of iOS and technology! 🙌🏼
Actually, there is no official confirmation from Apple about whether the issue affects all iPhones or just some models. But usually, such issues may vary from one device to another depending on the usage and installed software. So, we always recommend keeping the system updates up to date to ensure optimal performance. 📱💡
I submitted the same answer last time and when I sent it, it was different.
May Allah guide everyone
Ok, I have a problem - and I'm afraid that it causes the apps not to update. When I open the App Store, I turn on personalized ads or turn off personalized ads.
Moatam tells me I want to solve this problem and I want the color manager to ask this question or anyone else because the artificial intelligence may not give me accurately
Hi Habet El Baraka 🍀, I'm glad you reached out! It seems that you're having some issues with personalized ads in the App Store. To solve this issue, make sure that your privacy settings are set up correctly in your iPhone settings. Go to "Settings" then choose "Privacy" then "Ads". Here the "Update Personalized Ads" option should be open. If this method doesn't solve the problem, it might be a good idea to check with Apple Support. Don't worry, AI is just a tool to help us, and it can't change the accuracy of the information we provide 😄📱👍
In short, it's useful 😂 The iPhone needs a patch 😂
May Allah reward you. By Allah, the money we pay for Apple is only because it protects users and encryption, nothing more and nothing less.
This feature is enabled automatically. You don't need to do anything other than update to 18.1.
Thank you Mohsen for the clarification, very valuable information! 😄👍🏻 It will definitely be useful for readers using the 18.1 update. This information really highlights how Apple always strives to make our lives easier and more secure. 🍎🔒
Thank you very much for this article.
As mentioned in your article about the secret code that Apple recently launched in the iOS 18.1 update, which works to prevent anyone from accessing what is inside the users’ iPhone.
Does the user have to run it for the first time or does the code run automatically?
What to do? How to see BFU for the first time or AFU
Please advise me, thank you.
Where is the secret code?
