help...backlight button did not work - JASJAR, XDA Exec, MDA Pro General

I just bought O2 xda exec few days ago. But I found the backlight button doen't working. And i go to change a new one already. But it is the same. Also don't working. Is it the OS problem or hardware problem. :shock:

What exactly is it doing? On my Jasjar the backlight button will only turn on the backlight if it's off because of the timeout. It won't turn the backlight off, nor will it turn on the backlight if you toggled it by holding down the power button. It doesn't work the way I would expect, but apparently this is the way it was designed to work.

Yes, my backlight button only turns on the light for the screen, not the keyboard, what you would expect it to do both.

Does the keypad backlight on this thing actually work? I can't turn mine on whatsoever!!!
I don't want to return this phone back to O2, when none of them will work in the end.

The backlight button does work, but it works in so few situations that it's pretty much useless and a waste of a button.

key pad only lights up after you press a key if its dark enough
if you cover the light sensitive port above the xda exec script above the lft side of keypad then it will come on whenever you strike keyboard though i think screen backlight has to be on
some people are covering port with a small piece of black tape to set keyboard backlight on pernamently though im not sure what it does to battery life

just checked and screen backlight has to be on

I have set my keyboard lights to come on whenever you press a key. Much nicer

screen brightness goes to zero

Anyone else find that some software can cause the screen brightness to slide down to zero, so you have to go through settings and slide it back up via several irritating clicks. Not sure what software is doing it

yup
use to happen onxda1, happens only sometimes on xda 2

Yup it happens sometimes. I think I figured out when that happens.
It happens when you press the Power Button not all the way e.g. when you apply only minor pressure to the button. Normally this happens accidentally when you want to Power Off the XDA. SO instead switching off the the XDA, if you do that (i.e. press power button not all the way), the brightness will go all down to zero.
I think the "half press" of the power button to dim the display is an intended feature not a bug. Was the same on my iPAQ before moving to the XDA II.
I have had ythe odd occassion (twice only) where after a soft reset the screen brightness was set to zero. You have to go to the screen settings and slide up to your desired setting again.

Backlight keeps turning off

I keep finding the backlight on my XDA II keeps turning itself off, I have to go to the backlight menu and I find the "on battery power" backlight setting is set to minimum. It does this randomly with a fully charged battery. Might have to buy a torch if it keeps this up!!! Any ideas?
I thought I had the same problem, but it turned out to be my own fault.
My XDA II would be off and I'd press the [Power] button, to turn it on ... no backlight. I discovered, quite by accident, that if you press and hold the power button, it in fact turns off the backlight.
So ... when turning it on, make sure you just press the [Power] button and DON'T linger.
HTH
ardarby is quite right. It's a great option once you know about it to save battery... I use it all the time now, when I'm outdoors if you push and hold in the power button it turns off the back light. If you want it back on just do the same.. Push and hold the power button...
Nice one!
Cheers! I was on the verge of a 20 minute wait to speak to Orange support, thinking I had a hardware fault!
I had the same thing when I had my XDAI. Strangely it seemed to happen every time my gf had been using it, and in the end I worked out she had assumed to turn it "off" it was the same as Nokia's where you have to hold the power button down.
Saved me a similar call to o2!

thanks for the hint, I had the same problem with my qtek 1010, that I got mad at my kids (poor kids) every time they used it I get it back with no back light. It is a bit different with the 1010, you press for power, and then you can toggle between back light on/off by a second long press on the power button.
Well, now I see no need to buy a new one :lol:
this forum is superb! My problem with backlight off solved again
Thanks all

Backlight Button Faulty?

Hi,
Since i bought my Universal as the xda exec ive had two problems.
1. The touch screen stopped working keyboard worked fine. This was solved after a rom upgrade.
2. The backlight button does nothing
Isbnt the backlight button suppose to turn backlight of? if so why doesnt mine?
dunno about q1 but as for q2, the backlight key only turns on the backlight whe n the screen times out. Astonishly useless by design! You can remap it to use it like any other hardware button tho (with a bit of registry tinkering). Search this forum for how to.
There are 2 type of backlight:
(1) the screen
(2) the keyboard
the backlight of the screen you can turn on and of via the on/off button at the left side with which you turn on/off the device. For turning on and off the backlight without turning on/off the device you must press and hold the button.
the backlight button at the front is only for the keyboard. But this only works, when you set in the settings, that it should not use the light sensor to regulate the light.
thanks guys, your help is very much appreciated.
I found this a bit strange.
On my Qtek 9000, the backlight button (on device side) does nothing (even if light sensor not used).
The one which does this, is the 'SYM' key on keyboard... :?:
Ok, now I try it out. I was wrong: the light button at the side does absolutely nothing :shock:
so for what is that? how can I put a function on it?
lol, this is totaly true, on my o2 exec i thought i try it by disabling the sensor and it didnt do nothing. Whats it for?
Maybe it will have a function in a newer rom?
Hi,
You can change the function of this useless backlight key. You can make it to launch any application you want. Just follow the instructions on the first post of this thread: http://forum.xda-developers.com/viewtopic.php?t=34377&highlight=backlight
Enjoy!

simple display on/off question

Hi!
- Does the Universal turn on automatically when the display flip is opened or does the user have to press the Power button first?
- What exactly does the Backlight button do?
I need to know this because I'm investigating a possible wiring damage ...
Thanks!
.ox
Depends...
The Universal knows two different states. When you close the display while the device is on, and then open the diplay again the screen will come on.
If however you first press the power button to send the device into standby, and then close and open the display, the screen will not come on, the device will remain in standby.
The backlight button is useless, use the hack to re-assign it to a function of your choice.
Thanks!
That helped a lot!! 8)

[Q] Omnia 7 Home Button responsiveness

Hello all,
I have a question regarding the Samsung Omnia 7's home button and its responsiveness. I've heard some say that it's not very responsive, and that it takes a few presses for for the device to respond. Is this true? How responsive is the home button?
I've been using it for 2 weeks now and have no problems with the home button
Sometimes I have this issue. Thinking about sending it back for repair if the problem persists/gets worse. Curious fact: If you press hard at the bottom of the device, while pushing the windows-button - it won't react at all.
Make sure that you are not covering the light and proximity sensor..
You can experiment it by placing your hand on top of the phone and press the home button.. You will notice that the screen doesn't turn on!
That was it. Covering the light sensors at the top right disables the home-button. Very understandable given that you don't want it to turn on in your pocket.

But isn't that the point of having a lockscreen? what are the chances of pushing the home button, and sliding up the lockscreen in your pocket?
The power button wakes it up even if the sensors are covered, so it seems having this feature on the home button is an unnecessary annoyance.
For what it's worth...I don't want to have an empty battery just because something in my pocket pressed the home button and the screen lit up.
This feature is good -why should I press the home button when the proximity sensor is being covered?
Sometimes the home button is not responding at all. Only a reboot helps. Anyone with similar problems and a solution? Or is this a wp7-bug.

Read the posts above.
It's not a bug. The home button will not react if the LIGHT SENSOR is covered. It's designed that way, so if the button is pressed in your pocket your phone won't turn on and waste battery.
Try in a well lit area and do not cover the sensor at the top of the phone. The home button will work exactly the same as the lock button then.
If the sensor is covered, the home button won't react. If it's not, then the home button will.
End of story, moving on...

So in theory, if you are in a pitch black room, your home button will not turn on the screen? Don't think so.
........It's not the light sensor, it's the proximity sensor.

Sorry but that is simply not true (so not end of story....) I actually just tried to lay down my phone on a table and then cover the whole top of the phone with my hand (also tried with a piece of thick paper) so the sensor is covered. Then I tried to press the Home button, well it still works on my Omnia 7. I always return to the homescreen or my turned off screen will turn on - even with the sensor in the top covered completely - but what I cant is to scroll in the tiles or anything on the screen (sometimes), seems the sensor disables all my touch on the screen, but not the hardwarebutton Home in the middle - if you dont believe it, I could create a video of it.....
EDIT HERES A VIDEO:

I've had such a problem ... the home button not responding ...
also in conversation I could not hang up call, just a black screen would remain. Only remove the battery worked. when I got the jig, I put the new software and have no further problems
