iPhone AI Summary Won’t Show More? How to Fix It

Quick answer for iPhone AI summary show more not working: tap once, directly on the italic summary text of the notification stack. Apple designs summaries so that a tap expands them to show each original notification, and “Show Less” collapses them again. When tapping does nothing or the full text stays hidden, the cause is usually a notification setting (Show Previews set to When Unlocked, or the Count display style), a stuck Apple Intelligence model that a restart fixes, or a summary setting that needs to be turned off and on again.

This guide walks through every fix for a summary that will not expand, starting with the quickest and ending with resets you should only try last. It applies to iPhones that support Apple Intelligence (iPhone 15 Pro and newer, including the iPhone 16 and 17 families) running iOS 18 or iOS 26. Menu names below follow Apple’s support documentation for current iOS versions.

How iPhone Notification Summaries Are Supposed to Work

With Apple Intelligence turned on, the iPhone can condense a stack of notifications from one app, such as a busy group chat or several emails, into a one- or two-line summary. Apple marks summaries with italic text and a small summary icon. According to Apple’s iPhone User Guide:

• Tapping a summarized notification or stack expands it so you can see the original notifications.
• Tapping an individual notification after expanding opens the app.
• Tapping Show Less above the stack collapses it again.
• Touching and holding a notification shows quick actions, if the app offers them.

So there is no dedicated “Show More” button on most summaries; the summary itself is the button. Many people who report the problem are actually long-pressing, or tapping the app icon area, which behaves differently.

Quick Diagnosis: iPhone AI Summary Show More Not Working

Fix 1: Tap the Right Spot

1. Swipe down from the top-left of the screen (or up from the middle of the Lock Screen) to open Notification Center.
2. Find the stack with the italic summary.
3. Tap once on the summary text in the middle of the notification. Do not touch and hold.
4. The stack should fan out into individual notifications, with Show Less and a clear (x) button above it.
5. Tap an individual notification to open it in its app.

Why this works: iOS reserves touch-and-hold for quick actions and previews, and a tap on an already-expanded single notification opens the app. A single tap on a collapsed summary is the only gesture that expands it.

Fix 2: Change Show Previews So Text Isn’t Hidden

If Show Previews is set to When Unlocked, the Lock Screen hides notification content until Face ID recognizes you. Expanding a summary while the phone is still locked can show “Notification” with no message text, which looks like “show more” failing.

1. Open Settings > Notifications.
2. Tap Show Previews.
3. Choose Always if you want full text on the Lock Screen, or keep When Unlocked and simply look at the phone so Face ID unlocks it before you tap.
4. Check individual apps too: Settings > Notifications > [App] > Show Previews.

Privacy note: Always shows message content to anyone who picks up your phone. When Unlocked is the safer setting if others can see your Lock Screen.

Fix 3: Switch From Count to Stack or List

iOS can show Lock Screen notifications as a Count (a number at the bottom), a Stack, or a List. In Count mode, summaries are hidden behind the number until you tap or swipe up.

1. Go to Settings > Notifications > Display As.
2. Choose Stack or List.
3. Alternatively, pinch the notifications on the Lock Screen to switch layouts on the fly.

Fix 4: Restart and Update iOS

Apple Intelligence runs models on the device. After an iOS update, or if storage was tight, those models may re-download in the background, and summaries can stop updating or expanding until the process finishes. Apple Community threads describe summaries freezing until a restart.

1. Restart the iPhone: press and hold the side button and either volume button, then slide to power off. Wait 30 seconds and turn it back on.
2. Go to Settings > General > Software Update and install any available update.
3. Open Settings > Apple Intelligence & Siri and check that Apple Intelligence is on and not showing a “downloading” or “preparing” message.
4. Make sure you have free storage. Apple says Apple Intelligence needs several gigabytes of free space; check Settings > General > iPhone Storage.
5. Keep the iPhone on Wi-Fi and charging for 15-30 minutes so any model downloads can finish.

Fix 5: Turn Summaries Off and On Again

1. Go to Settings > Notifications > Summarize Notifications.
2. Turn Summarize Notifications off.
3. Clear existing notifications in Notification Center; older notifications keep their summaries even after you change the setting.
4. Restart the iPhone, then return and turn the setting back on.
5. In iOS 26, review Choose Notifications to Summarize and enable the categories you want. News and entertainment summaries carry a warning that they may change the meaning of headlines.

Fix 6: Check Per-App Grouping and Focus

• Notification Grouping: Settings > Notifications > [App] > Notification Grouping. Set it to Automatic or By App. If grouping is Off, notifications are not stacked, so there is nothing to expand.
• Reduce Interruptions Focus: this Apple Intelligence Focus mode hides notifications it considers unimportant. If expected notifications seem missing from an expanded stack, check Control Center for an active Focus.
• Low Power Mode: MacObserver’s iOS 26 troubleshooting guide suggests turning off Low Power Mode or Adaptive Power while diagnosing notification problems, since background activity is limited.

Fix 7: Language, Region and Last-Resort Resets

1. Confirm that your iPhone language and Siri language are both set to a language Apple Intelligence supports, in Settings > General > Language & Region and Settings > Apple Intelligence & Siri > Language. A mismatch can disable features.
2. Delete and reinstall the specific app whose summaries will not expand, then allow notifications again.
3. As a last resort, use Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This keeps your data but resets settings such as Wi-Fi passwords and wallpaper.
4. If nothing works, contact Apple Support, especially if the problem started right after an iOS update, since Apple often fixes notification bugs in point releases.

How to Turn Off AI Summaries on iPhone

If you would rather see the original notification text every time, you can switch the feature off entirely or per app.

Mail and Messages: When “Show More” Means Something Else

In the Mail app, Apple Intelligence can replace the first lines of an email in the inbox with a summary, and an open email has a Summarize button at the top. A summary preview in the inbox is not expandable; open the message to read the full text. If the Summarize button does nothing, check your connection and Apple Intelligence status, since long emails can take a few seconds. In Messages, summarized previews appear in the conversation list; opening the conversation always shows the full messages.

Frequently Asked Questions

Why does tapping my iPhone notification summary open the app instead of expanding it?

If the stack contains a single notification, or it is already expanded, a tap opens the app. Collapsed stacks with several notifications expand on the first tap.

How do I see the full notification instead of the AI summary?

Tap the italic summary to expand the stack, then read the original notifications. To always see full text, turn off Summarize Notifications for that app.

Why are my iPhone notification summaries not showing at all?

Apple Intelligence may be off, still downloading, or unsupported for your language. Summaries also appear more often for groups of notifications than for single ones. Restart, update iOS and check Settings > Apple Intelligence & Siri.

Can I turn off Apple Intelligence summaries for news apps only?

Yes. In iOS 26, open Settings > Notifications > Summarize Notifications > Choose Notifications to Summarize and turn off the news category, or switch off individual apps.

Do notification summaries work on all iPhones?

No. They require an iPhone that supports Apple Intelligence, starting with the iPhone 15 Pro and iPhone 15 Pro Max and including newer models.

Are notification summaries always accurate?

No. Apple labels them as summaries because they can misread context, sarcasm or headlines. Expand the stack to read the original text before acting on anything important.
