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
