Yes, you read it right, recently we shared something about the ‘Black dot’ crashing issue which was forcing WhatsApp on Android to hang and become unresponsive. Did you face it, if so, then it’s time for you to laugh in the face of your iPhone and iPad-owning friends and colleagues, as the same emoji character has now been shown to cause devices running iOS 11.3.1 and iOS 11.4 to crash and hang.
Android users in particular have been experiencing the error over the last few days with WhatsApp installed and running. This manifested when a specific emoji character is received on the device through WhatsApp Messenger.
Rather than being a single emoji dot, it was discovered that it otherwise comprised of thousands of individual characters which were invisible to the human eye. But again, it causes huge problems to the Android text rendering engine, causing it to literally abort and hang the device.
Now, the same issue has been discovered on Apple’s iPhone and iPad hardware running the latest firmware versions.
In the similar fashion behavior on Android, iOS seems also has issues processing the thousands of invisible characters, causing the device to run through an untold amount of CPU lag trying to process the data without permission. This ultimately eats up all of the memory of the device and causes the native Messages app to continually crash and leave the user unable to restore anything within that app. Given the nature of the bug and the fact that it’s apparent on Android and iOS, logic dictates that Apple’s watchOS and macOS platforms would also behave in the same manner.
Well! This particular bug isn’t malicious in nature, and believe that it isn’t capable of doing any lasting damage to the device or able to extract any data for unknown parties. However, it is extremely annoying and frustrating when you are left unable to use the native Messages app on Mac, iPhone, or iPad, meaning that the only way to protect or rectify the error is to somehow exit out of the Messages app and get to a point where you can delete the offending conversation in the list.
Like Google, Apple will deem this a critical bug considering it affects pretty much every device and there is no known way to combat it. So, with that in mind, we can only hope to expect a minor point release of iOS to fix it in the near future designed to eradicate the problem.
