Few know it but Google has a unit of work, called Google Project Zero, dedicated exclusively to find serious errors in different operating systems and apparently found a ‘bug’ in iOS that could block your iPhone. Just by receiving a specific message through iMessage, your device was blocked, forcing you to restore it.
In previous occasions, we have seen how some messages managed to block your iPhone or iPad, but in this case, it was not solved with a simple restart and you had to resort to a restoration of the operating system. This is a serious error that fortunately was corrected in iOS 12.3, for this reason, we always advise updating to the latest version, you never know what kind of errors Apple has managed to fix.
A message that forced you to restore your iPhone
Natalie Silvanovich, from Google Project Zero, discovered the error in mid-April and explained that it only affects iOS devices, for which macOS seems to be safe.
” On a Mac, this only causes it to crash and reappear, but on an iPhone, this code is in Springboard. Upon receiving this message, the Springboard will be blocked and reappear repeatedly, which will cause the UI to not be displayed and the phone to stop responding. This condition survives a full reset and makes the phone unusable after you unlock it. The only way we could find to fix the fault is to restart in recovery mode and do a restore. This causes the data on the device to be lost. ”
The worst of all is that once you receive the message you can not really do anything, you will be lost seeing yourself forced to restore your device. Fortunately, if you have iOS 12.3, or a more modern version, such as iOS 13, this bug is fixed and you have nothing to fear.
