A new Apple iOS 9 feature can update your phone's software overnight, however the tool is receiving some backlash.
According to a story on BuzzFeed, the automatic update takes you to the "Hello" screen that iPhone users typically see when they receive a new phone.
This means it shuts off all alarms and some users have been oversleeping. iPhone users are talking about the issue on Twitter, voicing their displeasure.
There's no word from Apple yet about this issue.
