As I mentioned the other day, there have been several issues reported with Apple’s latest iOS 7 releases, particularly with battery life and iMessage.
Fortunately, Apple have now acknowledged the iMessage issues and are now working on a futher update, presumably 7.0.3, slated for next week, that will resolve this problem
The most frequent complaint is that messages appear to be sent, but later appear with a big red exclamation point indicating they did not go through.
The simplest and most often-suggested work-around by users is to restart the device. Another option to fix iOS 7 iMessage issues to to disable iMessage, reset the Network Settings, and then turn iMessage back on. (To reset the settings, go to Settings → General Reset → Reset Network Settings.) The later work around is more annoying, though, and seems to require frequent repetition.
“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,” Apple said in a statement. “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.”
Since then, some users have complained about excessive battery use, typed letters that don’t appear on the screen, and Apple’s Siri voice-recognition service not recognizing requests. Apple released an iOS fix last week to tackle some security problems with iOS 7.0.2.
