Google devs Disabled the Translucent bars on Nexus 10 (Manta) because it "performs poorly on this device"... 2GB Ram and a powerful Quad-core Mali TS04 GPU and it performs poorly ?! May be because of the High-res display, I personally think it's a GPU issue.
I know not everyone cares about a the "Translucent bar" issue that can easily be reverted, but what I am trying to find out is a reasonable explanation from Google regarding this matter.
Manta source code includes the following code listed on [config.xml] which contains the device configurations, Screenshot below too.
<!-- Translucent status & navigation bars perform poorly on this device --> <bool name="config_enableTranslucentDecor">false</bool>
* Update [5-Nov]: I have contacted Google and currently awaiting a response, Hopefully I will get one...
* Google Reply [8-Nov]: Google's reply was a little disappointing but at least they promised to tell the users if they will "remove" any feature from the update, which is good. Here is the email:
Thank you for contacting Google, I'd be happy to help you out with your question on the KitKat update. I'll do my best to provide you with a solution.
Unfortunately, at this point in time, we can only provide information for updates that are supported by your device right now. Google will let all of their customers about what the new update includes. You will not be left in the dark on what Google added/removed from the update.
