Two Hidden iOS 6 Features: Late Night EQ, Message Alerts From “Contacts Only”

iOS 6

Apple released iOS 6 – the latest mobile operating system for the iPhone, iPad and iPod touch with over 200 new features almost three weeks back.

In this article, we take a look at two new features in iOS 6 that are not so well known.

Late Night Equalizer: 

Apple has added a new equalizer settings in iOS 6, which compresses the dynamic range of the audio output, reducing the volume of loud passages. You can use this setting while going to bed or when you’re listening to music on an airplane or in some other noisy environment.

You can enable the Late Night Equalizer setting by following these steps:

  • Launch the Settings app
  • Scroll down and tap on the Music option
  • Then tap on EQ
  • Scroll down and tap on Late Night to select it

The Late Night setting applies to all audio output—video as well as music and affects all sound output, including the headphone jack and AirPlay, just like any other EQ settings.


The feature is not available for iPhone 3GS, iPhone 4 and iPod touch 4G users.

Message Alerts From Contacts Only:

While notifications and alerts ensure we don’t miss new information and events, it can be really annoying when you get one for a spam text message. Thankfully in iOS 6, you can now silence the alerts from unknown phone numbers by limiting alerts only from your people in your contact list by following these steps.

  • Launch the Settings app
  • Tap on Notifications
  • Then scroll down and tap on Messages under In Notification Center

  • Scroll down and tap on Contacts Only option.

That’s it, you’ll no longer be disturbed by an alert for a text message from an unknown contact.

    They need to make it that you can make it a specific list of contacts as well. Its a old feature I use to love on my SonyEricsson phones.

    Another cool feature I haven’t seen anyone mention is customized vibrations, both for calls and texts on a universal and per contact basis, also per email account. Better yet, you can create your OWN custom vibration sequences. I’ve seen it on my iPhone 5 and my wife’s 3GS.

      I don’t know why anyone would down vote my comment. Factual and informative and related to the topic, at least slightly.
