Backlight resetting to minimum when device switched on

For some reason my device has suddenly started switching to the minimum backlight setting whenever it's switched on. If I go to the backlight settings and then adjust the slider it will stay at the selected brightness until it switches off. When it switches back on again it's at minimum brightness and I can hardly see the screen!
This started happening after I installed and then removed PocketZenPhone.
I don't really want to hard-reset the device unless I absolutely have to - does anyone know what registry key sets the default switch-on brightness?
Thanks,

I dont have the solution but I have had the same problem intermittently. Can be really aggravating in the dark because it can be hard to get to the proper screen to increase the backlight. Hasnt happened in a while. Have not been able to figure out what triggers it. Have not installed PocketZenPHone. Curious if anyone has an explanation.

yah, i've noticed this to, sometimes i'll hit the power button to take it off standby and the backlight would be off. first couple of times it scared the hell out of me cuz i thought the screen had broke or burnt out.
also i noticed the version of spb pocket plus i'm using (3.04 build 4195) doesnt adjust the backlight brightness.

Now that you mention it. the SPB Pocket plus backlight does not work for me either. Strange...

Well I think I've managed to "fix" this by setting the following;
Backlight Settings:
On battery power, turn off backlight if device is not used for [5 min]
Turn on backlight when a button is pressed or the screen is tapped
Power Settings
On battery power: Turn off device if not used for [3 minutes]
I think the key thing here is to have the device auto-switch-off BEFORE the backlight timer kicks in. Since setting the above three settings I have not had the same problem again.

Ill give it a try as well.

Hmm...maybe someone can help me. One day, my backlight timer settings when the PDA's not plugged in reset to 10 seconds (in the registry it has it as 7 seconds). I'll go in and change it to 2 minutes (the original setting I had it at), but the minute I turn it off, it resets back again to the 10 seconds setting. I even tried going into the registry and changing it, and it resets it back to 10 seconds. I suspect it may have something to do with an entry in the "scheduled tasks" but it looks like a complete mess. Is there some kind of scheduled tasks cleanup utility?
Thanks,

hello i have the same problem using phothet with WM6
Thanks
Nicolas

I had the same problem often about 15 months ago - it happened often each day.
I posted herw but had no joy with a solution - but then found one on Modoco (i was looking about March/April 2006).
Even with that - it has still done if perhaps five or six times since - and basically makes the phone unusuable if it happens somewhere or time with poor light.

My KJam backlight keeps changing by itself to dark
Suddenly my KJam backlight always turns to low without me doing so, then I have to change it to high, barely can see what I’m doing as it is almost black. This is kept happening especially after I installed Pocketweather. I reinstalled the Rom, it worked fine then suddenly it is back again when I switch the screen off, or automatically it is switched off, the backlight slider I find it at the lowest end.
Why thus is happening, it’s driving me crazy, please help me

Screen timeout problem

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.

Backlight dims, power button doesn't work properly...

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.

lock screen is gone

very strange, i have just noticed that my phone lock screen is now gone.
when i hit the hang up/power off button instead of locking the screen it goes black but when i hit another button it comes right back to the main today screen but no lock screen. bit of a problem when it does in the pocket.
any help??

hi
start - settings - menu -all settings - lock -(untick prompt if phone unused for) ----follow instructions -- reboot
regards
op

hold down your power button and lock the screen using that, then when you put the phone back into sleep it will wake up locked.
You may have to do this everytime after a reboot. Eventually mine sorted itself out and I no longer have to do it

This happened to me after I installed the HTC SMS patch. It also makes it so you can only preview your emails and not go into it by selecting. Installed and hard reset twice thinking it was a fluke. Nope.

i got the lock screen back by going to Settings / Change background of lock screen, then softreset. don't know why it went missing and why i got it back doing this... but it worked.

Lock Screen won't turn off

Hi there. I'm currently having an issue with my S7 edge where the lock screen won't turn off after some time. The screen does turn off when I'm using the phone normally from the main screen after some time passes but it's just the lock screen I have issues with.
Whenever I charge my phone or just hit the power button once to see notifications on the lock screen, it'll just stay like that until the same time the main screen timeout configured time passes (5 minutes) and this is getting annoying and somewhat draining a little bit more of my battery. Previously it was working fine and the lock screen would turn off after around 10 seconds or so.
Has anyone faced any similar issues with their phones? I haven't tried a factory reset yet but I'd want that to be a last resort.

Clear Background apps.
It happens when you left some games or apps by pressing home button but it keeps running. Hope they will fix this soon.

Have you tried pressing that little button on the right side of the phone? That usually helps.

Yeah...I already tried that with no luck. Even tried uninstalling some recent apps in case one of them was cause but it didn't work either. Any other suggestions?
The issue isn't with turning the phone screen off by pressing the power button, it's the lock screen itself not turning off after a few seconds when it usually does.

I'm having the same problem, had good lock installed thought that may have been the problem but after uninstalling that I'm still having the same problem with samsungs oem lock screen. I too would like an answer or fix for this. also to note, in developer options the stay awake is off and no apps running in the background.

I am having this problem now also. The screen will lock, but the display stays on but dimmed. I can tap the screen and it will get bright. Now I must click the side button every time I set my phone down or the screen will drain the battery.

I'm facing exactly the same issue. When the screen is locked, it stays on for the same time confirmed to when its unlocked. For example, 1 minute, instead of 10-15 seconds.
Any workaround discovered for this?

Did anyone find a solution to this problem?

I thought that I might've been the only one! This problem only appeared on my phone after the Nougat update, and it's extremely annoying as I rely on notifications waking the screen for my main messaging app.
