If any Focus mode is enabled, notifications from certain apps may be delayed or suppressed, depending on your Focus settings. In some cases, you may not receive a notification until you manually open the app. Check whether a Focus mode is active and review its notification settings to ensure the app is allowed to send notifications.


Then please check the following.

  1. Check your DND status - Settings > Focus [Do Not Disturb]; Use Focus on your iPhone, iPad, or iPod touch - Apple Support
  2. Three primary factors trigger the automatic activation of the Focus modes. Users have the flexibility to deactivate each of these factors based on their individual preferences.
    1. Automatic Activation: Driving, Fitness, Gaming, Mindfulness
    2. Smart Activation: Work, Reading, DND

Not every issue an individual encounters on their device can be attributed to an iOS update. iOS 27 or later may have coincided with what you are experiencing, but that does not mean the issue was triggered by iOS. Coincidence in timing is not, by itself, evidence of causation.


If the update itself were the root cause, then every device running that same version of iOS would exhibit the identical problem. In such a scenario, the forums would be flooded with countless posts reporting the same malfunction, creating an unmistakable wave of complaints that no one could possibly overlook.


The absence of such widespread reports strongly indicates that the issue is not a general, system-wide problem with iOS 27 or later, but rather something specific to the individual device, its configuration, installed apps, settings, hardware, or another interacting factor.


In short: iOS 27 or later may be a coincidence in timing, but there is no basis to conclude that iOS itself triggered the problem simply because the issue appeared after the update.


See what each update does: About iOS 27 Updates, About iOS 26 Updates, About iOS 18 Updates, About iOS 17 Updates, About iOS 16 Updates, About iOS 15 Updates, About iOS 14 Updates, About iOS 13 Updates, About iOS 12 Updates, and so on...

If you are referring to Cellular Voice Calls then...


Hold / Pause and answer other calls" is a carrier-specific feature. This means it is not something you can enable or disable directly on an iPhone; instead, it depends on your carrier’s network settings.


Additionally, the following features are also carrier-specific and require support from your cellular provider:

  • SMS & MMS
  • Wi-Fi Calling
  • Call Forwarding
  • Call Waiting
  • Call Merge & Conference Calls
  • Personal Hotspot
  • Voicemail (Visual or Normal) (except for Live Voicemail, which also requires carrier support)


If you are experiencing issues with any of these features, contact your carrier (the agency that issued your SIM/eSIM) for assistance.
