Android 5.0 LollipopOfficial Google Blog

Early this week, Sony completed the task of releasing the latest Android 5.1.1 Lollipop to all its Xperia Z series devices, and now the company is getting ready to roll-out the same update to a couple of more smartphones.

Android 5.1.1 Lollipop (build number: 18.6.A.0.175) bound for Sony Xperia M2 (D2303, D2305& D2306), M2 Dual (D2302) and M2 Aqua (D2403, D2406) has received the necessary certifications from PTCRB, reported Xperia Blog.

For the uninitiated, PTCRB is a cellular operators forum, which authorises certification program for devices operating telecommunication bands in North America. After receiving certifications from any of these regulatory agencies, it takes a week or two for companies (in this case: Sony) to release the OS update to devices en masse.

The Android 5.1.1 Lollipop update is said to bring enhanced overall stability and an improved ART (Android Run Time) making apps open faster than before. Issues with "Okay Google" will also been fixed.

The new update will bring Wi-Fi toggle directly to Quick Settings alongside Bluetooth. It also brings a fix for the memory leak issue that was reported in Android 5.0 Lollipop causing apps to crash abruptly without any warning and rectifies random app crashes of dialer and messaging apps as well.

Sony's update is also expected to come with Stagefright bug-fix, which if left unchecked might let hackers take control of smartphones with just MMS video riddled with malicious code.

To top it off, Sony will introduce selfie taking option via SmartWear. This means users can use Sony's SmartWatch 3 as a remote shutter button.

Once the Xperia M2 and M2 Aqua get Android 5.1.1 Lollipop update, Sony will complete the formality of releasing updates to all the devices, the company promised in June.
