Apple has officially stopped signing iOS 26.2 as of February 3, 2026. This means that once users upgrade their devices to iOS 26.2.1, there is no way to downgrade to the previous version through conventional methods. For users experiencing bugs or performance issues after the update, this makes the decision to update particularly critical, as reverting to a more stable version is no longer an option.
Conclusion
Although iOS 26.2.1 brings important security and feature updates, it is not fully stable for all iPhone 17 users. Commonly reported issues include app crashes, battery drain, Face ID delays, and connectivity problems. Users should carefully consider whether to update immediately or wait for future patches
