Apple has released iOS 9.3.2 update with bug fixes. Most importantly, iOS 9.3.2 fixes a Bluetooth bug in iPhone SE where some Bluetooth accessories could experience audio quality issues.
Being mainly focused on fixing bugs, iOS 9.3.2 does not bring any new features. As always, a compatible iPhone, iPad or iPod Touch can be updated via Settings or using iOS 9.3.2 IPSW.
To update your iOS device over the air, simply head over to Settings > General > Software Update and tap Download and Install. The latest iOS update will be downloaded and your device will be upgraded to iOS 9.3.2.
You can also choose to upgrade using iOS 9.3.2 IPSW. This will completely erase your device and take longer time for the process to complete. You will need latest iTunes and iOS 9.3.2 IPSW file for your device (links below).
