Sony has just released the Android 5.1.1 Lollipop update for the dual SIM variant of the Xperia T2 Ultra handset.
Since the device is already running on an earlier version of the Lollipop platform, the latest update only comes with minor changes but features an important security patch against the Stagefright exploit, according to the Xperia Blog.
Sony started the roll out earlier this week and is currently being conducted in stages. This means not only owners of the dual SIM device will be able to get the firmware upgrade at the same time. For others however, they will be informed regarding the update's availability through a notification.
The Sony Xperia T2 Ultra Dual came out in May of last year, two months after the release of its single-SIM counterpart. Both models came with the Android 4.3 Jelly Bean as their stock operating system.
Despite carrying the same specs except for the except for the dual SIM support, the update roll outs for the two models are irregular. The Xperia T2 Ultra received the Android 4.4.2 KitKat but the dual SIM version did not.
Although the the Xperia T2 Ultra Dual did not receive a KitKat update, it was upgraded to the Lollipop after version 5.0.2 arrived. It is not year clear if the single SIM variant will receive the same treatment but Sony will still probably upgrade the device in the near future, GSM Arena reported.
As for the Xperia T2 Ultra Dual, since it is already running on the Lollipop software, users can only expect to see minor changes in their devices after getting update 5.1.1.
But, as reported by various sources, the update features security patch designed to protect users against the Stagefright exploit. Although there haven't been reports regarding cases of users being victimized using the Stagefright tool, various companies that rely on the Android platform have released their own patches against the malware attack.
This is in response to the warnings issued by security experts a couple of months ago regarding the Stagefriight tool of Android. According to them, hackers can exploit this media playback tool by sending potential victims an infected file or malware through text messages, Digital Trends has learned. They warned that over 900 million Android users are at risk of being attacked using the Stagefright hack.
Hopefully, the recent update released by Sony, and the other patches from various companies, are enough to protect users and their personal information stored in their devices.
