Android™ Ice Cream Sandwich beta ROM available for unlocked 2011 Xperia™ smartphone models

Today we release an Ice Cream Sandwich (ICS) beta ROM, as a follow up to the previously released ICS alpha ROM. In line with our goal to support the open developer community, we want to give you the chance to try out our coming upgrade to ICS (Android™ 4.0) in this beta version.

While the ICS alpha ROM was an early preview, the ICS beta ROM have passed some certifications such as Modem type approval, and important functions like FM radio and GSM are turned on. However, additional certification and approval is needed before an official upgrade can be released. As previously communicated, we will upgrade all 2011 Xperia™ smartphones running on Android to ICS. Read more to find out what’s included in the beta ROM, and what other limitations apply.

Sensor HAL for Xperia™ phones available as open source

Continuing our open innovation initiative, we are now making the sensor HAL for the 2011 Xperia™ phones available as open source. So if you’re an advanced developer, you will now be able to access and configure the sensors of a 2011 Xperia™ phone on a deeper level. For example, you will be allowed to optimise the way the compass is used in a custom ROM.

In the good feedback we received on our previous open initiatives, we have seen a lot of requests for us to open source these files. And now, we’re happy to provide that opportunity. This is not part of open source archives that we are required to publish, it simply something we want to do for the community.

Stepping up our open source activities

As part of our continuing efforts towards openness and knowledge sharing, we are now stepping up our open source activities. For a long time, we have been one of the major contributors to the Android Open Source Project. We’ve also been active in the open developer community where we most notably published an ICS alpha release a couple of months ago. And now, we’re excited to release a couple of new open source projects that are available on our GitHub. As you can see below, we have just now released two very interesting projects as open source: the analysis tool ChkBugReport, and our WebGL implementation for Android™ 4.0.

This way, we would like to continue to be transparent, share our knowledge, and get external developer contributions to make the tools even better. On our GitHub, you can also find our Web SDK  project we published a while back, and a project called DrmLicenseService, which we will tell more about soon. Stay tuned for more information about open source projects going forward!
