Apple on Monday issued a minor update to iOS 10.3, which released on March 27, 2017. The new iOS 10.3.1 software update comes with a build number of 14E304 and is recommended for all users. According to release notes accompanying the download, iOS 10.3.1 includes bug fixes and improves the security of your iPhone, iPad or iPod touch. The software update can be downloaded over-the-air via Settings → General → Software Update on your iOS device.

Aside from bug fixes, iOS 10.3.1 brings back support for 32-bit devices like iPhone 5 and iPhone 5c. Apple’s security document sheds more light on bug fixes, acknowledging that iOS 10.3.1 patches a bug that could let an attacker within range to execute arbitrary code on your device’s Wi-Fi chip.

To fix the Wi-Fi vulnerability, a stack buffer overflow was addressed through improved input validation. This particular vulnerability was discovered by Gal Beniamini of Google’s Project Zero.

    Please fix the Bluetooth to car audio skipping for the iPhone 7 for goodness sake!!

    • BooBee

      That happens on my Bose wireless headset but not in the car. I thought my iPhone 7 just wasn’t paying nice with Bose.

      • Blip dude

        Happens on my iPhone 6S Plus but only with my Beats Studios. Powerbeats and Car stereo are no issues either. Beats Studios do not desync on iPad or other iPhones, only on my 6S Plus.

      • Jay

        Seriously? How long was the problem present for you?

      • omakad

        I got the problem since the iPhone 6s or whatever iOS launched with it. I have it on two different cars, with beats and especially with Apple’s own air pods. I can’t wait for it to be fixed.

      • Jay

        I noticed that it happens less on 10.3, much less but still present..

  • Rahimo

  • Eddie Flores

    Please fix the delay on Bluetooth in car audio please!!!! It’s a 3 sec delay

    • James G

      I find that issue to be dependent on the car manufacturer. For example, Acura cars up until 2015 models do that. It’s incredibly annoying.

        I have a 2017 Nissan Pathfinder
