Hello Rob.
That's comes from our developers. for you issue about the " Blade
Sleeping "
In most cases it's not a hardware limitation. It's about power
consumption. Power consumption is a very important aspect of user
experience. If you keep everything working when the phone goes to sleep,
you will definitely suffer a battery drain. I think Android has provides
you UI interfaces to control the behaviour of some hardware modules when
the phone goes to sleep (if it makes sense to have that module on during
sleeping). For example, you can have the bluetooth module working when the
phone sleeps. But surely it will incur a power consumption penalty. It's
up to you. For many other haredware modules, We don't see any reason to
have them on when the phone is suspended. For example, the light sensor.
What's the point of having light sensor working when the phone sleeps? For
these modules, users don't have any chance to control their sleep
behaviour. So technically you can do anything you like, surely at the risk
of a shorter battery life.
When USB cable is connected, the phone doesn't really sleep. Only the LCD
and some other modules are turned off. Generally the LCD(including the
backlight module) consumes most current on the phone. It's not necessary
to go to deeper sleep other than turning off LCD because after turning off
LCD, the USB cable supplies far more current than the amount that the
phone consumes. There is no need to perform a full sleep. It might take a
little bit more time to have the phone fully charged than in a full sleep.
But it's not noticable.
WIFI module is special. The chip has a limitation. It must be totally
powered off and brought up again when the phone wakes up.
Concerning the key issue you may have some misunderstanding. ZTE handsets
highly conform with Android conventions. What keys can wake up the phone
and what keys can turn on the screen? They are different things. You must
first wake up the phone and then turn on the screen. 7k_handset.kl is only
responsible for defining keys that can turn on the screen. You edit that
file but it takes no effect because these keys you add are not even
eligible to wake up the phone. Keys that can wake up the phone are defined
by the manufacturer. Users are not encouraged to change it.
Best regards.

[ztebladeopensource] wifi driver
Hi, I am still being asked the source to the wifi driver, you mentioned
that you couldn't provide it because it was given to you by a 3rd party,
can you please provide contact details for the 3rd party so that I can ask
them about it? Also, can you check the license that came with that source
just in case it is open source in which case you should be ok to release
it?
Thanks
Rob
