iPhone Not Ringing After iOS 27 Update? How to Fix It

iOS 27 includes several smaller but important usability upgrades. One of them is the ability to set separate volume levels for ringtone and system alerts. However, if your iPhone is not ringing after iOS 27 update, it can quickly become a frustrating—and even serious—problem. You might miss important calls from family, work, or your doctor without even realizing it. Fortunately, there are several simple steps you can take to fix the issue. Whether your iPhone is completely silent, too quiet, or only sometimes rings, this guide will walk you through what to check and how to get your ringer working again.

Let’s start with the basics and work our way through the more advanced fixes.

1. Start with the Obvious: Mute Switch and Volume

It might sound too simple, but it’s worth checking:

Mute switch: Make sure the physical switch above the volume buttons isn’t flipped toward silent mode. If you see an orange line, your phone is muted.
iPhone Models with an Action button: These models replaced the mute switch with the Action Button, which can be customized. Make sure it’s not set to silent mode by going to Settings > Sounds & Haptics > Silent mode. These iphone models include: iPhone 17e, iPhone 17, iPhone 16e and iPhone 15 Pro and iPhone 15 Pro Max.
Volume: While on the Home Screen, use the volume buttons to turn up the ringer. (The volume buttons only control the ringer volume when you’re on the Home Screen—not while inside apps.)

2. It Rings—But It’s Too Quiet?

If your iPhone rings but you can barely hear it:

Increase the ringer volume: Go to Settings, tap Sounds & Haptics, then drag the volume slider.
Test your speaker: Go to Settings > Sounds & Haptics > Ringtone > Classic, then tap Old Phone to play a loud sample. If it works fine, choose a ringtone that’s easier to hear.
Attention Aware Features: Your iPhone may lower the volume if it notices you’re looking at the screen. Check this by going to Settings > Face ID & Passcode, enter your passcode, and turn off Attention Aware Features if needed.

3. Lock the ringer and alert volumes in Settings

Go to Settings , then tap Sounds & Haptics.
Turn off Change with Buttons.

4. No Ring at All? Check for Missed Calls First

Open the Phone app > Calls. Do you see missed calls?

If there are no missed calls, the calls may not be reaching your phone at all. This likely means a carrier or network issue. In that case:
- Contact your carrier like Verizon or T Mobile to check for local outages.
- Ask them to verify that Call Forwarding or instant voicemail forwarding isn’t active on your line.
- Some carriers enable features like No Answer Transfer, which forwards missed calls to another number. If you don’t want this, ask your carrier to disable it.

5. If Calls Are Reaching You (But Still No Ring)

If missed calls do show up in the Phone app, that means your phone is receiving them—but something else is preventing it from ringing. Try the following:

Disable Screen Incoming Calls setting

Go to Settings > Apps > Phone. If Ask Reason For Calling is selected, any caller who is not in the list of your contacts will be required to provide their name and reason for calling before iPhone rings.
Selecting Never can help avoid missing important calls.

Disable Unknown Callers setting

Go to Settings > Apps > Phone. If Unknown Callers is on, any call from a number not in your contacts will be silenced and moved to Unknown Callers list.
Turning off Unknown Callers setting can fix iPhone that’s not ringing after iOS 27 update.

Disable Call Forwarding setting

Still in Settings > Apps > Phone, check if Call Forwarding is on.
Even if it appears to be off, some carriers can override this setting—so it’s worth double-checking with your carrier.

Turn off Focus Modes

Swipe into Control Center and turn off the Focus mode if it’s active.

Check your Ringtone Settings

Go to Settings > Sounds & Haptics and make sure a ringtone is selected. If no sound is assigned, your iPhone won’t ring.

Check Auto-Answer setting

Check Settings > Accessibility > Touch > Call Audio Routing, and make sure Auto-Answer Calls is turned off.

Check Communication Limits (Screen Time)

Go to Settings > Screen Time > Communication Limits.
Tap each section and confirm that both are set to Everyone, so your iPhone can ring for all contacts.

6. Final Step: Restart Your iPhone

If everything looks right and your iPhone still won’t ring, try restarting your device. A simple reboot often clears up temporary glitches.

Hold the side button and either volume button until the power slider appears.
Slide to power off, wait a few seconds, then press and hold the side button again to turn it back on.

Still not ringing? If none of the above solutions work, you can try Reset All Settings by going to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This won’t delete your data but will restore system settings to default. If that doesn’t solve the problem, wait for the next iOS 27 update to see if it will resolve your issue.
