How to Fix the iOS Black Dot Bug That Crashes iMessage
In 2025, users of Apple devices—including iPhones, iPads, and Macs—are still encountering a peculiar bug tied to a seemingly harmless emoji. Known as the iOS Black Dot bug, this glitch can completely crash iMessage and freeze your device, leaving users scrambling for a fix. Whether you’re using iOS 11.3, 11.4 beta, or other versions, here’s a complete guide to understanding the issue, why it happens, and how you can resolve it—without losing your data or device functionality.
What Is the iOS Black Dot Bug?
The “Black Dot” refers to an iMessage that includes a specific emoji (⚫) combined with hidden Unicode characters. These characters are invisible, but when processed, they overwhelm the Apple device’s processor, freezing the messaging app and even affecting system performance.
The message typically appears with a finger-pointing emoji followed by a black circle emoji. However, the real issue lies in the thousands of hidden Unicode symbols embedded between them. These characters exploit a memory processing loophole in iOS, overloading the device’s message rendering system.
Devices Affected by the Black Dot Bug
- iPhones and iPads running iOS 11.3 and iOS 11.4 Beta
- Mac devices synced via iMessage
- Apple Watches and Apple TVs connected to the same iCloud account
Even though the bug primarily affects mobile devices, synced Apple ecosystems can spread the issue if the message is opened across multiple devices.
What Happens When You Receive the Black Dot Message?
When the iMessage app receives a message containing the Black Dot, your device might:
- Freeze or lag significantly
- Crash the iMessage app upon opening
- Become unresponsive to touch
- Reboot spontaneously or drain battery faster
Even force-closing the app won’t help unless the message is removed. This is why users need a clear recovery method to regain access.
Step-by-Step Fixes for the Black Dot Bug
Option 1: Using Siri
This fix works best on devices with Siri enabled.
- Force close the Messages app completely.
- Activate Siri by holding the Home button or saying “Hey Siri.”
- Ask Siri to “Reply to [sender’s name].”
- Send multiple replies to push the Black Dot message off the visible screen.
- Reopen Messages, tap “Back” to the conversation list, and delete the thread.
Option 2: Using 3D Touch (on supported devices)
For iPhones with 3D Touch, this method is quick and effective:
- Force quit the Messages app.
- Use 3D Touch on the Messages icon and select “New Message.”
- Tap “Cancel” to return to the conversation list.
- Swipe left and delete the conversation containing the bug.
Option 3: Using Another iCloud Device
This works if you have another Apple device logged into the same iCloud account.
- Open Messages on the secondary device (Mac, iPad, or another iPhone).
- Do not open the infected conversation.
- Delete the conversation directly from the conversation list.
Warning: Do not tap the message to open it on the secondary device. This can cause the same issue.
Will Apple Release a Permanent Fix?
Apple has acknowledged the Black Dot bug and has since released stable patches through iOS 11.4 and beyond. However, issues like this serve as reminders of how Unicode characters can be manipulated for unintended consequences.
Users are encouraged to regularly update their devices to the latest iOS version. You can check for updates by going to Settings > General > Software Update. For enhanced security, enable automatic updates.
Real-World Experiences with the Black Dot Bug
We spoke with tech repair experts at an Apple-authorized service center in Chicago who handled over a dozen Black Dot-related service requests in 2024. Most users were unaware of the issue until their device began freezing repeatedly. One client, an iPhone 7 Plus user, said:
“I thought my phone had a virus. I couldn’t even scroll past the message to delete it. Siri was the only thing that saved me.”
Protecting Your Device: Best Practices
- Don’t open suspicious messages, even from known contacts.
- Disable message previews on your lock screen to avoid auto-processing buggy content.
- Regularly backup your iPhone using iCloud or iTunes in case of crash recovery.
- Turn on automatic software updates for iOS and watchOS.
