Apple recently said it was aware of an issue that several iPhone users have been experiencing with iMessage since upgrading to iOS 7, noting that a fix is being worked on. The Cupertino California company told The Wall Street Journal in a statement that it is aware of an apparentiMessage glitch in which some users’ messages go unsent, unreceived or sent as a text on various iPhone models running iOS 7.
Apple released the following statement regarding the matter:
“We are aware of an issue that affects a fraction of a percent of our iMessage users, and we will have a fix available in an upcoming software update. In the meantime, we encourage any users having problems to reference our troubleshooting documents or contact AppleCare to help resolve their issue. We apologize for any inconvenience this causes impacted users.”
That being said, there have been reports of a temporary fix to the issue. Many users claimed the following steps helped for a few hours before the failure messages began reappearing:
- Disable iMessage in Settings > Messages,
- Reset the iPhone’s Network Settings under Settings > General > Reset
- Reenable iMessage.
It should be noted that Apple didn’t make the patch rollout timeframe clear, though reports are claiming a third iOS 7 update, dubbed iOS 7.0.3, is set to release next week and may patch the issue.
