Firefox OS Update Adds New Features including Dual-SIM Support and Enhancements for Music Lovers and Gamers

The next update to Firefox OS is now available to Mozilla partners to implement in smartphones. The update includes several new features including Dual-SIM dual-standby (DSDS) support offering the flexibility of having two separate SIMs, additional camera features, simplified access to the music player and the ability to create unique smart collections of apps.

App developers will be pleased to see the arrival of new platform technologies such as WebGL, asm.js and WebAudio for creating immersive games with great audio effects.

Here are some more highlights from this release:

For Firefox OS users

Dual-SIM dual-standby (DSDS) offers the flexibility of two lines with compatible phones: A highly demanded feature, DSDS now allows people with dual-SIM devices to individually manage two different SIMs for calling, texting or data through the simple “SIM Manager” UI. For example, you might wish to swap between a business and home SIM or if traveling may want to use a local SIM to eliminate roaming charges. It’s also possible to import contacts from each SIM into the device.

Capture sharper images and videos and locate them faster: Continuous autofocus (dependent on device compatibility) and flash are now supported, empowering you to take better photos and videos. The Gallery app also has several feature and performance improvements including content arrangement by month and file-information display, showing useful data such as date taken, file type and file size.

Direct access to your music: Several improvements for media apps are in this release including access to music controls in the notifications tray or from the lock screen. The FM Radio app can now also be played through the phone’s loudspeaker.

Adaptive App Search enhancement: With adaptive app search, you can now also search for apps from the Firefox Marketplace, in addition to the Web, making it easier to find your favorite content.

Smart Collections: Firefox OS groups your apps into smart collections on your homescreen relating to specific app categories, for example: Social, Games, Music, Showbiz etc. By clicking on one of these categories, let’s say gaming, you will see a list of all your installed games and clearly delineated below; a list of suggested new gaming apps you might like to try out. You can also save specific searches that interest you on the homescreen as new smart collections (examples: recipes, sports, news) by tapping the star icon under the search bar.

More options for messaging:

  • MMS/SMS: You can now send MMS messages to email addresses and add a subject line. Firefox OS will automatically switch an SMS to an MMS if you decide to add an image or video. You can also save message drafts and can opt to receive delivery notifications when a message is read by the recipient.
  • Email: Now supports email notifications and POP3, one of the most popular ways to connect to email accounts.

Advanced Bluetooth makes sharing easier: Multiple Bluetooth file transfers are now supported, allowing you to share multiple photos or MP3s with other devices simultaneously.

Performance improvements: Enhanced scrolling performance and faster app startup times throughout the various system apps (e.g. calendar, address book, camera etc.), means you can get to what you’re looking for quicker.

Languages supported: Bengali, Bulgarian, Catalan, Chinese (Traditional), Croatian, Czech, Dutch, English, German, Greek, Hungarian, Italian, Polish, Portuguese (Brazil), Romanian, Russian, Serbian (Cyrillic and Latin), Slovak, Spanish, Turkish.

For Developers

Improved support for Graphics and Gaming: This update will ship with some great optimizations for games. With WebGL, asm.js and WebAudio support now included, developers will be able to bring superior, immersive gaming experiences to Firefox OS phones.

Experiment with NFC: This update includes NFC enablers, starting with the availability of the WebNFC API. Developers will be able to begin experimenting with NFC pairing and tag reading in their apps, with additional NFC functionality coming in future updates.

Improved Gecko Platform Capabilities with new WebAPIs: This release is based on Gecko 28 and includes several new WebAPIs. Shared workers enable more powerful data processing and resource sharing, so developers can write faster applications. Among the new APIs, SpeakerManager gives developers access to the phone’s speaker, allowing applications such as the FM Radio to be listened to without headphones. The WebIccManager API, which allows support for multiple SIM cards, has also been updated. These new APIs continue to build more functionality and features into the Web for app development.

Audio Streaming with RTSP: We have now built the RTSP streaming framework and have completed support for audio streaming allowing developers to leverage their existing music technologies to target Firefox OS users.

This Firefox OS update is now available for handset manufacturers to deploy to their existing in-market phones and for developer phones.
