Since the bug surfaced late last week, some have been inserting the offending character into their Twitter names and encouraging others to spread it in tweets. It has also released updates for watchOS, tvOS, and macOS to prevent the bug from affecting those platforms as well.
Since iOS 11.2.6 is a minor release which has received little testing, no new features have been introduced into the operating system. Users have noted that it somehow also applies to the macOS versions of Safari and Messages.
Unfortunately it wasn't the first time Apple's software has proved to be susceptible to an odd message. The problematic Telugu character quickly became every Android users' favorite character, with people adding it in their social media profile names, just to crash their friends' iPhones.
The glitch that was detected last week seemed fairly simple but powerful enough to crash an iPhone or iPad. According to Apple's release notes, the roughly 42 MB download "fixes an issue where using certain character sequences could cause apps to crash". To make things worse, it could even reportedly crash the entire iOS Springboard software that runs the home screen on devices. Tap "Download and install" next to the iOS 11.2.6 listing and you'll be good to go.
The bug affects iPhone owners who are sent a specific character from the south Indian language Telugu, which blocks access to popular apps such as Messages and WhatsApp, The Verge reports.
