what are the major beta bugs in ios27 beta 2

Apple’s beta 2 notes and early tester reports point to a few major bugs/issues rather than one single blocker: Safari’s tab bar can disappear, some Safari Intelligence features may show as available before they actually work, and testers are still reporting rough edges around battery life, app compatibility, and general stability.

Quick Scoop

The biggest complaints showing up so far are:

  • Safari UI glitches, especially the tab bar vanishing.
  • Beta-level performance and battery drain, which is expected but still a top pain point for early adopters.
  • App compatibility and random rough edges that developers and testers are still surfacing.
  • Reports from community posts about lingering Bluetooth, keyboard, AirPods battery status, lag, and iPhone Mirroring problems.

What seems most serious

From the release notes, the clearest documented issue is the Safari tab bar bug, because it affects core navigation in the browser.

The other official note worth watching is the mismatch where Safari Intelligence features may appear enabled even when they are not fully available, which can be confusing during testing.

What testers are saying

Forum and social chatter suggests beta 2 is still not fully smooth for everyday use. People are mentioning sluggishness, keyboard glitches, Bluetooth trouble, AirPods battery status oddities, and some unresolved Messages and iPhone Mirroring issues.

That said, some testers also say beta 2 improves Wi-Fi, screenshot behavior, Siri speed, and overall stability compared with beta 1.

Practical read

If you are deciding whether to install it, the safest summary is: beta 2 looks more polished than beta 1, but it still has the usual early-beta instability and a few specific bugs that can get in the way.

For a primary phone, the main risk is not one catastrophic bug — it is the mix of UI glitches, battery drain, and unpredictable app behavior.

TL;DR

The major beta bugs in iOS 27 beta 2 are the Safari tab bar disappearing, Safari Intelligence availability glitches, and broader beta instability such as battery drain, app issues, Bluetooth/keyboard problems, and some iPhone Mirroring complaints.
