Today I had an alarm set, when the alarm went off I tapped hit the power button on the top of my phone to turn the screen off (and hopefully the alarm... but only the screen went off). The alarm continued to go, but no matter what I did, I couldn't get the screen to come back on.
I can fully interact with the phone (as if the screen was on). For example, pressing talk twice redailed my last call. Pressing power prompted to shut the phone off (could hear the "blurp"), etc.
So, after shutting the phone off (or resetting with pinhole reset), the display works fine while it is displaying the "Cingular - Raising the Bar" nonsense. As soon as that screen is done (where it would have normally showed the today screen), the screen just goes off...
Any ideas?

nevermind, when I put it under a bright light I realized the screen was on, the backlight was just off... somehow I must have hit some shortcut to turn the backlight off.

Don't sound too relieved...
Say hello to the Backlight bug.
You're backlight will keep setting itself to the lowest setting after every soft-reset, when you let it go into stand-by itself.
I'm still sufferering from it. It started when i first installed PocketZenphone.
So just want to give u a warning. Everytime you reset your phone, remember not to let it go into standby itself. Either tap the power button and turn the screen off, then turn it on agan. Otherwise, the Backlight will go to low again.

Anyone know how to stop an accidental clicks or other screen presses from taking place when I've got the phone to my face during a call?
Si.
I use a freeware app called Screen Off, download it here:
http://www.handango.com/PlatformPro...latformId=2&N=96806&productId=125781&R=125781
Basically when I make a call or answer a call I have screen off assigned to a button, so I can then press the button to turn the screen off. To turn the screen back, just press the power on button.\
Hope this helps,
Or maybe you could simply turn PDA off with a single power button press...and when you're finished simply turn it on. Remember that the radio is always running (unless you hold the power button for 5s).
My screen turns off automatically after about 20 seconds when on a call - haven't set it to do this - in fact can't even find an option - it just seems to be the default setting. The only way to turn it back on is to press the green or red buttons, or just flick the volume control either way - works for me. (O2 XDA Mini s)

Macrinus - thx that works a treat.
That's weird, your screen turning off after 20 seconds, mine turns off as configured in "Turn backlight after..." and "Turn off device...".

Yeah, it is weird - bit annoying, but sensible really to save the power - Perhaps its just the device turning off then, with the phone still running .... comes back to life with a flick of the volume though - touching the screen won't re-activate it. Will have to time it a bit more closely !

Radio on screen off
I too turn the device off when I'm on a call (although I only discovered I could without ending the call this morning). Otherwise, my ear activates the Start menu.
Doh!
if only the backlight is turned off, the screen WILL still react to face contact!
I understand that either the device (less the phone side!) via power button, or the screen must be turned off via an utility.
It may exist, but I know no proggie able to lock the touchscreen without turning it off!
(pitty, my axim X50v can lock the screen without turning it off via a Hw sliding button9
Hi all,
I upgraded to an O2 Exec a little over a week ago from a Blue Angel.
Initially I had a few concerns about it, but thankfully I found this forum, and have managed to get a number of enhancements, from increased storage and better radio (v1.09) to being able to turn on the flash light using a hardware button. My Exec is now running faster than my Blue Angel ever did, and hasn't frozen once. I've already become quite attached to it.
One thing that I think would be useful would be to have the unit turn on when the lid is opened, and off when it is closed. In the Power settings you can uncheck the box that turns off the device if it is not used for x mins, which has the effect that the screen will come on whenever the lid is opened. However, because the device is still running the battery still takes quite a hit even though the screen is turned off, and even when you lower the cpu speed.
Is it possible to turn the device on and off by opening and closing the lid?
Cheers
Rowan

Hi, I have mine set to come on and off when you open close the lid, and it's set exactly how you have said. Power settings, and stop the device going off. And Backlight settings, stop the backlight dimming, and lower the backlight when on battery mode.
There is no "off" mode like Nokia handsets, only Standby, which is what happens when the screen is closed. (I think).

You're not really going into standby mode by closing the case, try switching on wifi or bluetooth and look at the flashing indicator LED, it will still be going whien the case is closed. Nowtap the power button to put the device into standby, no more flashing LED. The phone LED still flashes which is a good thing otherwise you wouldn't be able to recieve calls in standby.

From what I know, the Universal has no real OFF mode, only standby, EVEN WHEN YOU PRESS THE POWER BUTTON. On mine, BT and WiFi still flashes even when I press the power button or just close the screen.
Pressing and holding the power button turns the backlight off, a quick press (or tap as I said before) makes it go to standby and should turn off everything but the phone part.
Okay well weve taken a really fun detour discussing the technicalities of standby and 'power off' but lets digress for a moment back to the original topic...
Rabangus, seems the best option you have is what you were doing. The hit to battery shouldnt be that large. I gave it a try not too long ago the way you and the other member had it set up again, and yes youll definitely have to charge it every night but it was doable. But I wasnt using wifi or bluetooth either. I am surprised that using Xscaler it still takes way to much battery. I assume thats what you are using to lower the CPU.
Oh well unfortuntely thats the way it is chief.
I have a HTC Magic from Orange (PL), unmodified, without root access, Android 1.5 out-of-box. Recently, I've noticed annoying issue on my phone. If I don't press "end call" red button to turn screen off, it will be on forever - the phone is on the desk for 15 minutes, I'm not touching it, and the backlight is still on, with my Android desktop (not lock-screen) on the screen. It's look like there is no timeout to turning backlight and screen off, although this was working some time ago. I've tried to change settings like timeout value in minutes, WiFi sleep mode etc. but without success. It is so annoying that I have to remember now to press red button after using a phone. Anyone can help me?
P.S.: I don't have aFile or Dark Keys installed.
I have had the Touch 3G for nearly a year now and for the last 3 months I have had this recurring problem which is fixed with a hard reset but will recur again after about 6 weeks. The symptoms are:
1. When turning on, the backlight dims just before the HTC flash screen and startup sound (when it says "Smart Mobility")
2. Touching the screen doesn't bring the backlight back on.
3. Pressing the power button doesn't turn the screen off from this dimmed state, but after pressing touching the screen will turn the backlight back on.
4. Pressing the power button again will now turn off the screen, but pressing it again won't turn the screen back on! If I call it from another phone, the vibrator goes on but it doesn't ring, the screen stays off and you can't answer the call. If you hang up on the other phone it keeps vibrating and you need to do a soft reset to stop it.
If I do a hard reset the symptoms are gone and reinstalling the exact same software doesn't cause the problems immediately but withing a month or so it happens again. All I did just prior to these problems was use TomTom a bit more than usual, but otherwise nothing different. I have used TaskManager to see if there is anything weird running in the background but it all looks fine. I have had a cursory look through the registry but also can't find anything?
Any advice would be appreciated.

Sounds like it's going all haywire. If you've had it less than a year, I'd send it in real quick. Sounds more like a hardware problem.
I don't think it is hardware as a hard reset fixes it...it just recurs down the track. I have done a hardrest and reinstalled all my apps and it is working great again but I was wondering if I should be checking somewhere in the registry for an aberrant setting. I am u using a backup image program so at least when it happen again I an restore my system more simply.
But then again, all the symptoms you mentioned point to a hardware defect. You could try to find a tweak, but like all electronic devices, it's the luck of the draw. Try emailing HTC and see what they say.
Hi,
I experienced today a strange behavior:
I used my nook, turn off wifi, let it in my bag for 1 or 2 hours and when i tried to wake it the screen didn't turn on.
At first i though it was SOD but when i looked closer to the screen there was something on it, it was the CM7 boot logo (the tony hawks droid
The logo was not very visible, most like old "ghost image" on CRT screen when he same image is displayed for long periods of time.
I should have taken a photo, i will if it reproduce.
Kinda sounds like it was rebooting without turning on the backlight. Could you see the arrow circling? I've had "n" turn on the backlight with no image, but tapping power turns off the backlight, then tapping it again turns the screen on properly.
Sounds like somebody's state machine has a leak...
i will never know (i pressed power 8s, if it was booting, i just stopped it)
