Backlight settings getting lost.

Hi,
I have run into a problem half a dozen times now when I turn on the phone and the backlight isn't working and pressing the backlight button doesn't make a difference.
When I check the settings the backlight levels have been set to Zero.
I haven't yet had a chance to track down why it is happening, but was wondering if anyone else had come across the problem.

Hello there!
Been lurking for a bit but finally decided to join in.
Not got much to add really as I am still learning about the device, however I am suffering the same problem. Happened quite a few times now and I can't discern a pattern.
Any geniuses got any ideas?
Great forum by the way. Learnt lots already.

All I can tell you is yes, it's happened to me before. Almost gave me a heart-attack, because I though the machine was failing - the light just switch off on its own accord while I was reading an e-book at night.
Still no idea why.

I have been suffering the same problem since the rom update. It seems to happen mostly if I have some program active in the background when the device powers itself down from idle or the clamshell is closed.
For me, holding the power button down for a few seconds seems to take it back to the defined level setting.
Clueless as to why it happens though.

Well, I'm not alone
This has just started happening to me, too.
I usually have to do a soft reset to be able to get the backlight back on. Once it's back up and running, I go into my settings and find nothing has changed since I set the backlight timers for both battery power and external power. I've even got it set to turn the backlight back on when pushing a button or tapping the screen -- and yet, when I do that, nothing happens. I've tried holding the power button down for a few seconds, but all that does is give me a soft reset.
I've been running the AKU2.3 ROM for about a week, and this problem started occurring yesterday on my Cingular 8125. I'd sure like to know what's causing it and how to fix it.

HTC P3600i Freezing Problem

Hi Guys,
I'm new here, but have been following and reading these forums for quite some time now. Great Stuff!
anyhow, my problem, recently purchased a HTC P3600i PRO. Put a custom ROM on it, seemed to be running great over the last few weeks, but my problem is this. Now and then my phone pda will lock up and I'm forced to reset it. What happens is, I am still unsure as to why this happens, but lately it's started freezing up, and when I click on my start button, it shows my menu, and then when I click programs, it shows as "empty" when I know there's nothing empty, it's filled with stuff, randomly this happens to my settings window as well. Basically stuff randomly dissapears from my start menu, shortly after, 5 to 10 seconds, it locks up. The next thing I do or click on after seeing things disappearing from my menu, it freezes. I then have to do a soft reset, and after doing a soft reset, it's as if it's done a hard reset and wants me to re-configure the time, click on all 4 corners, etc.. I use have to use SPB Backup to do a full restore of my phone/settings/contacts/software etc..
Can anyone help?
Also, just to update.. I restored my phone with a backup today, and it seems to be running well again for some strange reason. Is it because it's overheating? getting hot or what? I'm not sure what it's doing. Please help

Figured it out
My backlight whilst on battery was set to brightest. figured it was overheating as it felt warm too.. I turned it right down to 3 bars from lowest, and it's fine now
Guess it my screen and battery were getting quite hot and the CPU was overheating. All resolved.

I got a HTC p3600 for about 10 months. i used to have the backlight set to minimum.
now i update my rom and it got crashes so often, almost every day, and I need soft restart the device all the time when get crash.
The worse, sometime my display picture just broken + crash, and I need more than once to restart the pda. When I restart the device sometime the display just turn black color moving from top to bottom, or sometime with colourfull dots on screen, and the device does not want to be restart.
In that case i take the battery to turn off the device.
Sometimes i need to wait some minutes until i can restart normally the system.
It usually crashes when it is connected to the computer via usb (charging the battery) and i need to use it. (i check and it is very hot)
Also, when i use wifi it tends to crash (very hot too)
Since i upgrade the rom my backlight settings are set higher...i reduce the backlight, to reduce heat and test the system stability, but i really think it is crashing due to overheating.

Home Screen Scrolls by Itself

The title says it all....
The Boss Lady's phone started "self-scrolling" the home screen today.
Whenever she wakes the phone, within 30 seconds (her display timeout) the home screen will scroll left or right until it reaches the end.
You don't have to touch the screen. Just holding the phone in your hand seems to trigger it. Rebooting didn't help.
Since I noticed the scroll seems to start sooner if the phone is moved, I tried the G Sensor calibration function. No joy.
I also tried setting her display timeout to 30 minutes and putting the phone on the desk. After about 15 minutes and no scrolling, I set the timeout back to 30 seconds.
Has anyone else's DINC done this?
Incredible, Android 2.1, rooted and s-off. Otherwise bone stock.
Same as mine and mine doesn't self-scroll.

Mine does this when the optical trackball gets dirty. I think the light and dirt tricks it into thinking it's being used..
Sent from my ADR6300 using XDA App

My daughter's did the same thing after a day or so. I removed the screen protector and reapplied it all of one millimeter to the left. I have no idea how or why, but it stopped scrolling to the left after that.
Same thing as you though, mate. I have the same screen protector on the same fone and mine hasn't given me a lick of trouble.

just clean the screen/optical sensor. mine has done the same thing a couple of times. It even scrolls through random buttons when im on the web sometimes.

Thanks for the tips!
Her phone hasn't self-scrolled all morning. I may have wiped off the trackball while looking at it last night.
Thanks again.

Screen wont come on after Sleep

Hey guys. Phone's been good for a long time. Ran cm6 and CM7 nightlys for a long time.. Tonight is real first big issue
WTH.. I already tried Wiping, and nandroiding.
Now booting with old builds, and new build #33 when the screen goes to sleep after initial boot. I can't get it back on no matter what. Needs a battery pull first. Odd.. I'm hoping something isn't wrong with my nexus one. It's really acting up now.. Basically the phone turns on and runs, but the minute it falls asleep it's done for. I can wake it with my Power button, but only the soft capacitive key's light up. No screen. but I can turn the screen/key's off and on with no problems with the button. Just the screen never comes on. but I can watch those softkey's do it. So the power button is working, but it could be going out. but seems to work every time.
I've officially wiped tonight. I tried a nandroid to a past build, I'm thinking I might have a hardware issue.
Any idea's. Screen wont come on after falling asleep. At all, requires a battery pull. (saw this in CM forum) guy said fix permissions fixed it. any idea's?

This might be happening because of the WiFi/BT connectivity bug. If you watch the logcat (or maybe it was in kmesg), you'll probably see lots of errors regarding mmc0.
On the other hand, anything that would get the CPU stuck at 100% throughtput, might do the same, and it might be some other bug.
Try to turn off WiFi and BT and do the same, see if it helps any.

Neither are enabled.. Now it is doing this For sure, completely everytime. I can pull battery and boot phone. Seems to run ok, can open apps. go to market. whatever. but when I go into settings I get Activity FC and it freaks out. I just tried to power off my phone. It's been at the Shutting Down spinning circle part for over 15 minutes. Is it possible the build it 512mb went bad and thats why it can't resume from standby, and stuff?
I'm still testing things. but I've completely wiped and had no luck. and also nandroided to a good working version also. Basically if my phone goes to sleep at all. I can't turn it back on. I have to pull battery.

Same thing here..
Screen will not wakeup from sleep unless I do a battery pull... Any updates?

Its been 1 year since nobody posted, anybody came up with an explanation/solution?
This Issue just appeared in my phone after two years of use.
-When the screen goes to sleep it won't be possible to switch it on again. Either via the power button, time up or proximity sensor.
-The phone and the touchscreen work as always, haptic feedback reveals my unlock slider is still active and the phone can recieve calls and notifications.
-Plugging in the phone or using another button won't revive the screen either.
-The backlight of the screen turns on, but the screen remains black.
-Only removing the battery and waiting at least 10 seconds before putting it in again will let the screen to come back.
-Shouldn't be a software problem as i have wiped several times everything that could be wiped and instaled diffrent Roms, even tested ICS.
-In my case, removing the microSD doesn't change anything.
-Swapping batteries also doesn't help.
Anybody out there with the same problem?

My N1 developed this issue just a few days ago- I'm looking for a solution as well. I have all of the symptoms you've described, apart from the backlight turning on as I have an AMOLED display. It's interesting to know that the backlight turns on, as it and the video signal are controlled separately (and impossible to distinguish on an AMOLED display).
I've reverted mine back to an official shipping ROM, something really ancient, and it still occurs.
Mine is also right around the 2 year mark. There are a handful of other threads on various forums which describe the same issue with the only resolution being sent in for servicing. I don't know whether it was the screen or the motherboard that was replaced, which would be very helpful to root causing the issue.
I'm not sure whether it's an issue with initializing the screen itself as it is is functional and can turn on after a battery pull/sitting for a few hours. I would guess it's something to do with a capacitor or similar, since the way to get the screen to work is a battery pull +time or to wait a long time before turning the screen back on.
It's a shame, too, because everything else is working just fine in my N1 and I think it is the perfect combination of a phone.

Format your SD-Card. It's known to fix it.

Thanks for your suggestion, but unfortunately it does not fix my issue.
I've tried different SD cards, repartitioned & formatted the card (previously had a sd-ext partition), and even running it without an SD card- all either won't turn the screen on during boot (starting with the battery out) or will fail to wake the screen.
My logs don't show the mmc0 errors which would indicate an issue with the card; it seems to be pretty normal for the screen turning on and off, just that the screen doesn't actually initialize and display anything.
About a week before the screen wake issue developed, I had a problem with the camera and gallery thinking that the SD card was not present. I eventually wiped and reloaded an older ROM and the problem went away.

I replaced the AMOLED screen and it now properly works. Since the screen was able to turn on by itself after an hour or so, I suspect it might be a capacitor or something that's gone bad on the flex cable itself. I'm not sure how much effort I'll spend tracing it down, but I might at least give it a shot.

Change the Screen
Had same issue with a Nexus 5. I changed the screen and it worked great.

Did you install any applications from the market? Is your phone freezing while a certain application is open or does it freeze even on the homescreen? If you have a lot of applications installed try to deinstall and look if it becomes better. If not try a factory reset. If it still freezes than return it for a new one.

Would you mind saying what you were doing when it locks up?
If it's during Music, it doesn't actually lock up, it just shows a black screen for about half a minute. Everything still functions, it just doesn't show.

Two times trying to answer a call the screen would not unlock nothing would work I had to take the battery out and just todayit was sitting on my desk and it would not turn on when I tried to use it
The green message light was on very dim and I had to take the battery out

I have a feeling there is a bad batch of units out there.
Try factory reset and see if it continues to lock up, if it does, return it for another.

Sounds like a broken phone. Try a factory reset (if you return it they anyway ask if you did that) and if that won't help get a new one....

Same thing happened to me yesterday, the light was very dim green and the phone did not respond until I pulled the battery. It hasn't happened again.
I've already had to replace my Atrix for another issue. Right now my confidence in this phone is not very high, but it is brand new. Lots of issues will probably pop up and be fixed via software updates- at least I hope thats the case.

It really feels like all the issues people are having with this phone are software related. Maybe motorolla will just cave and give us gingerbread with no blur

I've had the same problem while playing music...over the past 3 days after about 30 minutes of tunes it'll lock up and after another 5 reset itself...i've done the reset after the second and it still does it...i'm bout to take it back and exchange it...i expect glitches but damn.
Motorola Atrix (stock)
AT&T Fuze (Energy.RAPHAEL.21916.Sense2.5.Cookie.2.0.sencity)

I have had the issue happen 2 me twice in 3 days, the last time was when adding the note widget to screen. It was not completely locked up just the touch screen, i could press the power off button but the touch screen would not let me shutdown

something you might want to try if a factory reset doesn't work would be a reinstall from the recovery menu.
power your phone off
hold the down volume key and the power button
release the power button once the phone begins to boot
keep holding the down volume button until you see "fastboot" at the top of the screen
now be careful, the down volume button navigates through the boot options and the up volume selects one
so press the down volume button until you come across "android recovery"
once you see it press the up volume button to select it
once you get to the screen with the exclamation mark tap the bottom right of the touchscreen, this should pop up the recovery menu
select wipe data/factory reset
let the phone do it's thing
good luck
I've seen this resolve some audio codec issues that were causing the phone's mic to not work, dunno if it'll work for your issue but it can't hurt to try.
best of luck

I have found a fix for my lockup issue. If the screen is on and lockup (no touch screen) press the power button 2, turns off the display and turns it back on and everything continues to work fine.

I have the same problem (screen randomly locks up once or twice a day, buttons dead) and have found the above "solution" to work perfectly, also. The problem however is that pressing the power button twice and unlocking the phone is not exactly elegant especially if the screen locks while you are trying to answer an incoming call.
I changed my battery settings to "performance mode" as I read somewhere that that might help. I will let you know if that seems to resolve the issue.

Changing battery setting doesn't seem to do anything. I still get my share of frozen/locked up screens a few times a day. Still have not figured out how to replicate the behavior. It really does seem random.

I've been suffering from this as well, I'm going to try to exchange my phone and see if that helps.

Exchanged my phone today. So far I haven't seen any locked/frozen screen issues. I am relieved. Maybe there are just a few bad units out there.
Also for what it is worth ... the lady at AT&T told me that taking out the battery while the phone is on would fix it. Since I never figured out how to replicate the behavior I couldn't verify that her suggestion would indeed actually fix the problem and demanded an exchange anyways.

atrix does lock up and have glitches
lock up glitch:
While in standby (screen black), it locks up. You obviously don't know when exactly it happens as it's lying around in standby. When you press the powerbutton to wake it up, nothing happens. You can try what you want, long press, several presses, just dead phone. As if the battery losts juice, but 2 times it happened and the battery was above 50%.
Tired to connect the charger while in that lock-up state. Nothing happens The notification light remains black as well.
The 2nd time this happened to me, I had the idea to call myself and see if just the powerbutton has a glitch and the phone is actually running just remaining in standby with a black screen. But nope, the phone didn't ring or wake up.
Only way to recover is to take the battery out.
I didn't mess with my phone and was very careful in which apps I installed. The only ones I have are very populoar 4+star apps:
extended controls
easy profiles
the other apps are most of the time not even running:
photoaf, vignette, imdb, nytimes, fb, skype, pandora, screen filter, droid light, prozoom5x camera
No games at all installed...
The 2nd glitch that happened to me a couple of times is that the finger print sensor is not working: It doesn't display any message as in " did not verify, too short, ..." it's just dead, the only way to get in is to punch in the number code.
This is typically fixed after switching the phone off fully.
Of course skype also doesn't work on my atrix (well known mic issue)

It happened to me as well. I had installed some apps but when it froze it had been off (the screen that is) so it was sitting then when I tried to open it by pressing the power button the green light came on but it would not wake. I removed the battery, replaced it then it did the same thing again (including the green light). I removed and installed the battery once more then it was fine. It must have been something in the backround but not sure as to what that was. Hasnt happened again though.

strange, skype worked for me... oh well.
did you ever find a solution for the lockup issue, have the same thing, very frustrating but not as frequent as you thankfully.

My Atrix started to freeze up when I undervolted the CPU using SetCPU and I would have to pull the battery out and restart it. I increased the voltage settings and it hasn't locked up since, so if you have undervolted your CPU and your phone is locking up, you should increase the voltages.
