New Xperia Concept release adds improved tap-to-wake and battery fixes (MOB31E.Z1.3657)

by XB on 18th October 2016

in Firmware, Xperia Z3 series

xperia-updateSony Mobile released a new firmware update for Xperia Concept users last week, moving the build number to MOB31E.Z1.3657. 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.

Other changes centre on fixing some of the battery info issues. So, now you are able to turn off the battery percent value displayed through the System UI Tuner. You can find the System UI Tuner in your Settings menu, but it needs to be activated first. To do this, swipe down on the status bar and long-press the settings cog until it starts spinning. You will then be able to toggle “Show embedded battery percentage”.

Other updates include the use of the latest Xperia Home launcher (10.2.A.1.12) with Google Now integration, the latest Google Security patches for October 2016 as well as a new version of the InTouch feedback app (1.8.1). The full changelog can be found below.

The team also added an Easter Egg within the latest release, which took a few days for the community to find. We’ve got details below if you really want to try and find it yourself (don’t scroll any further!)

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.

    Hello guys, what is the name of the app used in the pics here which is showing the internet-speed in the status-bar? Is it a Xperia-only tool?

  • Utham
  • Bashar Shehab

    Nope. Who said that?

  • Don_Alduck

    “– Tap to wake now checks the proximity sensor” – Should’ve been added ages ago!! I hope we, Z5 users will receive some of these features in the near future.

    Any idea when this gets to a Canadian Z3 owner? I have the last update but Bell I guess hasn’t received it yet.

  • Derek Wright

    Good news about the double tap to wake as that has affected my Z3 from the beginning. I still have the October build but welcome this update thank you all for this new build!

  • Olsun

    So noticed this cogwheel turns to on my Xperia X performance. Just hold it

  • razorg

    Oh it was the Beta program, not the Concept program that they stopped. My bad, sorry :)

  • razorg

    Oh thank God!!! You’re absolutely right man. Double-tap-to-wake is such a useful feature for me but I kept it off since the first day I got my Z5C as it kept opening up in my pocket and sent texts/made calls on its own. And I seriously don’t understand why Sony had been so reluctant to fix this feature up until now…

    How to update Xperia Z2 to this new update?? When we will receives this update?

  • Frode P. Bergsager

    The hardware of the proximity sensor was not designed to be for checked for status in sleep mode, and the Concept Team had to use creative ways to implement this. Due to this it took a long time for them to get official approval for this little tweak.

    I updated my Z3+ and then activated tap to wake up. At first I thought it was working fine only I thought so. Later during the day I noticed my battery was draining like crazy and my phone was heating up. Then I realized that it’s started all over again with all kind of apps open and crazy stuff going on. Swtiched off the tap to wake up feature again.

    I don’t know so far what has happened but I’ve noticed that battery has draining much faster than using official release MM on Z3C. Course I like using Concept on my phone than the official one but if it continues acting like mentioned I’ll tend to go to official. Anyway I respect the work of the team that has worked on this simple and effective Concept. Best so far, indeed.
