List of Known Bugs

Detailed Description

Users experience sudden device reboots during App Store downloads and installations. The issue occurs most frequently with large apps (500MB+) and appears to be related to memory management during the installation process.

Trigger conditions:

  • Installing apps larger than 500MB
  • Multiple app updates running simultaneously
  • Device storage below 10% free space
  • Background app refresh enabled for many apps

Workaround

  1. Free up storage space (keep at least 15% free)
  2. Install apps one at a time instead of multiple simultaneously
  3. Disable Background App Refresh temporarily
  4. Restart device before installing large apps
  5. Update apps during off-peak hours when device is idle

Note: Apple is aware of this issue and working on a fix for Beta 4.

Steps to Reproduce

  1. Open App Store on affected device
  2. Select a large app (e.g., games over 2GB)
  3. Tap Install or Update
  4. Wait for download to reach 80-90%
  5. Device reboots during installation phase

Detailed Description

Face ID becomes unresponsive after device enters deep sleep mode. The TrueDepth camera appears to initialize but fails to recognize the user's face, showing "Face ID Not Available" error.

Affected scenarios:

  • Device left idle for 30+ minutes
  • Overnight charging
  • Using Low Power Mode
  • After iOS system updates

Workaround

  1. Restart device when Face ID stops working
  2. Disable Auto-Lock temporarily (Settings > Display & Brightness)
  3. Use passcode as backup authentication
  4. Reset Face ID and set up again (may need to repeat)

Temporary fix: Keep device screen timeout at 2-3 minutes to prevent deep sleep.

Detailed Description

iMessages sent from iOS 27 Beta appear as "Delivered" but recipients on older iOS versions never receive them. The issue affects both individual and group chats.

Impact:

  • Messages don't reach iOS 16 and earlier users
  • Group chats with mixed iOS versions break
  • Photos and attachments also affected
  • No error message displayed to sender

Workaround

  1. Temporarily disable iMessage and use SMS
  2. Ask recipients to update to iOS 17 or later
  3. Use alternative messaging apps (WhatsApp, Telegram)
  4. Send test messages to verify delivery

Apple's response: Fix confirmed for Beta 4 release.

Detailed Description

Abnormal battery drain occurs when device is idle, particularly during overnight charging. Battery usage logs show system services consuming excessive power.

Main culprits:

  • Background processes not sleeping properly
  • Location services polling too frequently
  • Network scanning even in airplane mode
  • System analytics consuming CPU cycles

Workaround

  1. Enable Low Power Mode before sleep
  2. Disable Background App Refresh
  3. Turn off location services for non-essential apps
  4. Disable automatic downloads and app updates
  5. Force quit all apps before locking device
  6. Use Airplane Mode overnight

  4. Disable WiFi Assist (Settings > Cellular)
  5. Reset Network Settings as last resort
  6. Use static IP instead of DHCP
