Apple has released the first developer beta of iOS 27 following its announcement at WWDC 2026, but reports from users indicate that a serious issue may cause certain iPhone 15 Pro and iPhone 15 Pro Max devices to become completely unresponsive.
The reports have raised concerns among users eager to test the new features, prompting recommendations to avoid installing the initial beta on primary devices.
Issue Appears After Force Restart
According to multiple user reports, the problem often occurs after performing a force restart on the device.
When the issue is triggered, the iPhone may become entirely unresponsive, displaying a black screen and failing to react to power-on attempts or charging connections.
So far, the issue appears to be primarily affecting iPhone 15 Pro and iPhone 15 Pro Max devices running the first developer beta, while it remains unclear whether other iPhone 15 models are similarly impacted.
Why Users Should Wait Before Installing the Beta
Developer beta releases are intended for testing and often contain bugs and unfinished features. However, this particular issue is considered more serious because it can render the device unusable until recovery procedures are performed.
Users who rely on their smartphones for daily activities are therefore advised to postpone installation until Apple releases updates addressing the reported problem.
Using a secondary device for beta testing is also recommended whenever possible.
Recovery Options for Affected Devices
Users experiencing the issue may be able to restore their devices using a Mac or Windows PC by entering DFU mode and reinstalling the operating system.
The process requires an internet-connected computer, a compatible data cable, and either Finder on macOS or Apple Devices/iTunes on Windows.
Once the recovery process is completed, the device can be restored to a stable version of iOS.
Importance of Backing Up Data
The incident serves as another reminder of the importance of creating a full backup before installing any beta software.
Recovery procedures may erase applications and personal data if a recent backup is unavailable.
With the official launch of iOS 27 expected later this year, Apple is anticipated to release additional beta updates that address current issues and improve overall system stability before the public rollout
