screen brightness goes to zero - MDA II, XDA II, 2060 General

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
Regards,
Mike

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.

Random BackLight Bug

Hi, first time posting! so hello everyone 8)
I got xda exec, i had this problem with the first rom and the latest one too. For some random reason when my phone comes out of standby sometimes my backlight is off. i struggle to see my screen and when i check my backlight settings (brightness level) "on battery" its set to off on the slider. When i set it higher my backlight works. Also my backlight button does not respond when this happens. It just randomly happens but im starting to notice it more and more. Any ideas peeps
Try:
1- pressing the button beside the volume slider.
or
2 - pressing and holding the power button.
Hope that helps

thanks but i tried both, doesnt work. the only way it comes back is by going to backlight settings. Is there a file that could be corrupt that stores the information about the backlight settings?
Is the box "turn on backlight when a buttonis pressed or the screen is tapped"?
Other than that i've not got a clue. Someone who knows a bit more? any ideas?
JAmes
yeah thats ticked. the only way i get the back light to work when this happens is pushing the slider up, the one in the battery settings
seems real odd.
If noone else has a suggestion a hard reset might help, dont know if you've tried that yet. If you do this dont forget to back up everything.
JAmes
Hi,
I think it really is the POWER button: if I press and hold it for a few seconds, the slider goes to zero and the light goes off. Press and hold again restores the old situation.
Peter
My wife's Magician did this sometimes too.
Turned out that in her case it was because when you hold down the power button to turn the phone off (for a second or two) it doesn't actually turn the phone off, just the backlight. (Of course it all goes dark, so it looks like the phone is off if you don't check too closely.)
Then when you press the power button to turn it on again (after it's timed out and turned itself off), there's obviously still no backlight...
May not be your problem, but give it a check...
In nearly three months, I've had this happen perhaps four times. My device has the "on-battery" backlight set at one notch, to save the most power, and I guess something must just move it that one notch down to off.
So far there's been no uniform circumstance, other than it's guaranteed to happen at night under low street or room lighting so that I can't see the screen to get to and re-adjust the setting.
A hard reset doesn't help. I've reset numerous times with different ROM versions and had the problem reappear - but very infrequently as I said.

Soft reset question

Hi,
I've read on here that you can do a soft reset without taking cover off and pressing the actual reset button, but I can't find it again. I've looked on hints and tips, wiki, and searched. Can anyone help please?
Cheers
You'll be needing the TouchX Reset & Wifi shortcuts then
You can get them off this post...
http://forum.xda-developers.com/showpost.php?p=4947950&postcount=1
It creates 2 shortcuts in your start menu. 1 for resetting, and 1 for toggling wifi. You can then add to your quicklinks, if you so wish.
Hope this helps
You could always switch off + switch on but johncmolyneux suggested works as well, although I used a cab so as when I push the switch off button, I get a new menu with various options, including soft reset.
Forgot which one it is though
Snerkler,
Some good suggestions here. Be aware that these will only work if the device is NOT in the grip of death, as I call it.
If it has died then there's no option but to take the back off and either press the little red button or take the battery out.

The 'out of the box' method, without resorting to additional applications is to press and hold the Power key for 3 seconds.
This opens up a context menu which includes 'Power Off'. This is a full 'power off' state with all background processes stopped. Pressing the power button again restarts the phone as in a soft reset.

So turning the phone off and on again is a soft reset???? If that's the case why are there cabs for soft reset, seems a bit strange to me. Wish I'd known that before when installing some of the cabs and taking the back cover off to press the reset button

I know what you mean about the "grip of death" lol. Been there already.
Turning the phone fully off then on again is the same as a soft reset. A simple on/off isn't.
If the device goes through the splash screens on restarting (as after the power button 'hold' switch off) that is a soft reset.
I use a stand alone program called psShutXP which is available on This Page - download the VGA version. It runs as a small Screen Off/Suspend/Power Off utility.

I'm not sure what you mean by fully off, and simple on/off. Are you referring to power off, and sleep? In which case I was referring to power off, ie hold power button and then select power off

Sorry - could you explain that please? Is there a difference between turning the phone off, and "fully" off?? I assume you're not refering to simply switching off the display when you say a "simple on/off", as that's not off at all.
You've lost me there mate.
There are 3 or 4 suspend states- sorry, but I can't remember what all 4 are
There is 'screen off' which simply turns off the screen but keeps all currently active programs running. This is only available by using a 'Display Off' or 'Screen Off' switch such as the 'Toggle Screen' option in Media Player. WFi and GPS remain active in this state.
The next is 'Suspend' by pressing the power button. This turns off the screen and some functions such as WiFi and GPS and some media players also stop working but the phone remains responsive and timed notifications will still work.
Next is the 'full power off' I mentioned which you get by pressing and holding the power button. This turns off all functions, phone features and stops all notifications working.
That's what I was clumsily trying to say when I mentioned that a 'full power off' has the same effect as a soft reset- as opposed to a 'screen off' or 'suspend'.
[Edit: Having tried this a little more, it may be that the HD2 doesn't differentiate between states 1 and 2 ?. Due to the lack of hardware button configuration, Media Player's Screen Toggle can't be assigned to a button. psShutXP's Display Off button works, but on turning on again, the lock screen starts, which shouldn't happed with a simple display switch. ]

Touchscreen Not Functioning Correctly

The screen on the my streak has been slowly degrading, to the point where i can barely do basic functions of the phone. It doesnt register touches or swipes a large percentage of the time. If I long press on the background to bring up the add shortcut widget popup, it usually will bring the phone back to 85% function. But if I lock the screen and try again, I have to go back to longpressing until I can click apps.
Often presses will register along the top bar and bring up the notification screen or short menu when I am clicking anywhere but on the top. It has happened several times while typing this.
Has anyone had Touchscreen problems with their Streaks?

Do you have a screen protector on and maybe some debris between it on the screen?
I'd recommend aligning the screen.
User Manual said:
If necessary, you can calibrate your touch screen as follows:
1 Press and hold the power button and then touch the Power off option on the screen to turn off the device.
2 Simultaneously press and hold the volume up button and volume down button .
3 Without releasing the volume buttons, press and hold the power button , until the device turns on the configuration screen.
4 Press the volume buttons to move the highlight bar on the screen to the Screen calibration option.
5 Touch the Camera button to start the touch screen calibration. 6 Wait for the device to reboot.

Also you could enable the debuging mode by typing in *#*307#*#* in your dialer, then in your app list you should see some new apps.
Open up Dev tools the select Pointer Location
Also another one is EmList and then select "Touch_Panel" theres a handful of diagnostic tools there that are pretty fun to mess with to see if something is physically wrong with your screen
Oh and to hide/disable debugging mode, just type in *#*308#*#*
I do also have some screen issues i had 8105 went back to 8023 and was working fine until today that it was acting up, but is better than 8105 which only let me touch half the screen, now it lets me do about 80% of the screen from bottom to top. I do have a screen protector, when I was running 1.6 didn't see this issue. Also i noticed that sometimes when my fingers are a bit sweaty the touch input doesn't work that well.
No screen protector, stock 1.6. Will try debug, thanks.
It happens with sweaty hands with dry hands its just messed up.

I just used the 6 step block method and it seems to have solved my issue. Help very much appreciated!

How long did it take to reboot after you hit the camera button?
I had to do mine yesterday as the lower part of the screen wasn't registering touches properly, as if it was about 50 pixels out.
First time round it didn't boot up with the volume keys held so i popped the battery off and started again (seems to be a common issue with this device). Then it was pretty much as standard for the boot. Keep the buttons held til the menu pops up, choose calibration, leave it until it says it's done and then reboot.
Again, should reboot as normal but if it doesn't try popping the battery off. The rear cover seems to cause a fair few issues with this!!
oh and running the calibration fixed the issue for me!

Turn screen on with a touch

In the display setting we can adjust the screem timeout. Mine is on 10 minutes for example.
Is there any application which can turn on the screen just with a touch on the screen (instead of pressing the power button) ?
Would be very nice together with the application "Unlock with WiFi"
I mean is there any application which enables the functionality to get the screen back (phone is not locked) only by touching the screen (instead of pressing the power switch on the top).
I know, folks, it is not a big deal to press the power switch, it is just a little bit more comfort to touch the screen only
I don't, believe so, but you can use the volume keys:

Hi scoob800. Thanks, but the volume keys would be pritty "the same" as to press the power button.
Generally spoken. Is it possible (and in case it is) and is there any application which can detect a touch on the screen, even if the screen is off ?
Well, the only thing I can think of is to set your screen to never autolocking and have a screensaver app that leaves the screen black. If you do that your battery will probably drain a good bit seeing as your screen will always be on.

You can achieve this with NoLED, but that is not its intended purpose. I will explain how: When you get a notification that would normally trigger your LED, NoLED displays a customizable icon on a black screen. With SGS, which it was developed for, has samoled screen and black uses little to no bat/cpu. This is NOT the case with the Atrix, your battery WILL suffer. So battery aside.. Set NoLED to display the time (that way its always on even when you dont have a new notification). Now play with the settings, tell it to "wake up" with the home key. TaDa!
the short answer is feasibly NO. having the touchscreen on at all times will DESTROY your battery life. your only option is to enable the volume buttons.
I use the volume buttons with no lock screen ..... waaaayyy better then powerbutton

OK. But to be honest, what is the difference to use the volume buttons instead the power button ? I would like to avoid this mechanical stress of these buttons. As I used my last phone ( a Samsung) for 8 years, I am afraid, my ATRIX will not make it such a long time
But I got an other idea. What about one of the four "softkey" buttons ? For example the home button.

The problem is they're still softkeys and not actual hardware buttons. Using the volume is just easier to press depending how your holding the phone. That and your spreading out that wear of the power button across 3 different buttons.

Soft keys will waste a lot of battery, it isn't a good way to turn on your screen by either soft keys or touchscreen

[Q] Touchscreen not working on lock and reset screens

In the last couple of weeks, when the pattern lock screen is displayed, it intermittently doesn't accept touch input. If I power off and on the screen quickly, it then accepts touch input fine.
Similarly, if I press and hold the power button (with the phone on), it brings up a "Phone Options" screen, with options for Silent, Airplane, Profile, Reboot and Power Off. Touch input does not work at all on this screen. I'm working around this by using the Quick Boot app.
Otherwise, touch input works fine, so I don't think it's a hardware problem.
I've seen something similar when Google Nav gets in front of the lock screen. Touch doesn't work until I power off and on the screen, and enter the lock pattern. Could something invisible be getting in front of the lock and power screens?
Using Pongster's HyperDroid-GBX-v12 (2.3.3).
Hey there,
Maybe the ROM h doesnt function properly on your device. Try shifting to another rom. All are equally amazing. If you do not want to shift, try running task29 and start the process all over again

Have you read the thread about the unresponsive touchscreen, where pressing hard on the end call button fixes the screen touch? I assume your problem is in essence the same; once you press it hard enough to actually unlock the screen the touch works fine.

That probably is what the problem is. Btw to everyone, I haven't noticed a difference in pressing it really hard, I noticed that pressing it a lot of times does the trick

Thanks for the feedback. I don't think it's the ROM, been using GBX-v12 since it was released, and previous versions before that.
The symptoms do seem similar to the other thread, but others report it on many screens. I only get it on the lock and reset/power screen. Otherwise, it works fine. However, those screen are brought up after pressing the power key ...
I suppose if it is hardware, then it's likely that cable issue. If it's software, then a reset should clear it, so I might try an ICS ROM from scratch first.

Thanks for the tip. You're right about the symptoms getting worse, it now occasionally stops working on other screen
I'm using any button but power to turn on the phone. To turn it off I've added "Go to sleep" to the notification widget bar, which I assume is the same as pressing power??
Not quite as user friendly and sometimes I forget not to use power off, but it'll do for now!

Yes that will work! I used it cause I got lazy and didn't feel like changing the key file but it's much easier to use the green call key instead of the notification power widget

Try this:
Lock the screen normally, screen turns off.
To turn it on again by pressing any other screen buttons other than the power button.
I found that if I do it this way, the screen runs normal.
