Apple just uncovered a new text bug that uses the Unicode writing system to overload the memory of its text messaging app, causing it to regularly crash. While the developers are still working to fix the issue, there are things you can do to avoid locking up your device.
What is going on?
A bug, known as “Black Dot,” is locking the messaging app on Apple devices running iOS 11.3 and 11.4 beta with Apple TVs and Apple Watches also at risk.
Black Dot is activated when an iOS user sends another user an iMessage (this is not an SMS) with an emoji of a black dot with a finger pointing at it. Loaded with plenty of invisible Unicode characters, this emoji will overwhelm the CPU and memory, forcing the messaging app to stop functioning and possibly lock up the device.
The affected user may be lucky enough to close the app, but the bug will remain when the program is opened again, causing everything to crash.
How do I squash this bug?
Apple’s development team is still working on a patch to address the issue, but you can apply a temporary remedy to keep your device going.
