Sony Mobile Releases New Xperia Concept Build (MOB31E.Z1.3657) With Battery Fix

For those taking taking part in the Xperia Concept program, Sony has released a new build (MOB31E.Z1.3657). If you’re unfamiliar with the program, it’s basically

a beta initiative enabling Xperia users to trial concept software builds for Xperia devices.

As for what the new build brings with it, Xperia Blog writes:

The update fixes a long-standing issue that many Concept owners have had in the past, where the phone would wake unintentionally if double tap to wake was enabled. An example of this is if the phone was in your pocket, constantly waking the display and draining the battery. Now, the proximity sensor will be checked before tap to wake is enabled, which should avoid any unintentional activation.

Unfortunately, not a lot of Xperia phones are eligible for the program as it stands but for those who are, this is how you check to see if you’ve received the new build.

All users on the Concept programme should already have the update by now, which mainly constitutes the Xperia Z3 (D6603)and Xperia Z3 Compact (D5803). If you have not received it, check out Settings > About phone > Software update to download the latest version.

The official changelog for the build includes:
