Apple's iPhone, iPad and iPod touch are now receiving the fifth iOS 10.3 beta. The software update introduced changes and improvements, but when exactly is the official launch date of iOS 10.3?

Perhaps the most notable feature of the latest beta is its new Apple File System, or APFS, that can free up more space on the iOS device. According to Ars Technica, APFS can also improve the device's data integrity and support for solid-state storage and encryption.

Updating an iOS device to iOS 10.3 will also update its file system to APFS but the existing data in the storage will be retained. However, Apple still advises users to backup their device's data just in case the software update deletes it.

Another notable feature introduced by iOS 10.3 beta 5 is the addition of the Find My AirPods functionality. According to 9to5Mac, Find My AirPods will be handy in locating the lost, cord-free earbuds, which rely on Bluetooth connectivity. To use it, your other Apple device must be within the range of the place where you may have lost the AirPods (five to 10 meters).

The software update also added Safari support for Reduced Motion preference and Siri backing for cricket scores from Indian Premier League and International Cricket Council.

Improvements in the CarPlay system were introduced, too. It's now capable of quickly pulling up albums and songs from the Music tab, and upcoming music is displayed on the Up Next screen. In addition, CarPlay users can now access and switch between media, communication and travel apps without going to the home screen.

The Podcasts app now has a widget, while the Settings app now displays an apparent user security section. Maps' Weather data, meanwhile, now displays 3D Touch forecast.

The official release date of iOS 10.3 is still unknown at the moment, but its full launch is expected to happen this month. The software comes with an upgraded version of WiFi Calling, which allows iPhone users to make or receive calls and texts on their other Apple devices as long as it's connected to the iCloud.

The feature is similar to Verizon's WiFi Calling, but iOS 10.3's is better because it still functions even though your iPhone has been switched off or connected to a different WiFi network. This will be handy when, for instance, your iPhone's battery is dropping and you really need to call your boss. In this case, you reroute the call to your iPad or Mac computer. WiFi Calling also works even if your phone has no signal.
