Screen not shuting off - Nexus One Q&A, Help & Troubleshooting

I had this problem before with OS 2.1 and now it's back with Froyo,I set my screen to shut off after 30sec but if I don't do it manually the screen will keep lighted up (though with 20% brigthness).
What's the damn problem????
Is it an app,the intersect kernel or a hardware bug??

[Q] Phone app does not work properly +delay when bringing the phone up from sleeping

Hi everyone,
some days ago, I've got a new display into my phone. It is working fine and everything is running good except two things:
- The phone app does hang during an outgoing call. I cannot hang up the call, because there is a black screen, or the phone does not accept input either. When the screen keeps black, I can go back to the home screen pressing the middle button. But in the "system tray" there is no phone symbol. The behavior is changing from call to call. Sometimes the process crashes.
- When the phone is not used for some seconds or minutes it takes up to ten seconds to see someting after pressing the middle button. An interesting aspect is that when the mp3 player is running, there is no delay. Whenn I press the middle button the screen comes back immedialtely.
I have the Firmware 2.2.1 running and executed a hardware reset two times.
Has someone an idea what I can do to bring the phone app to work properly and to decrease the delay when I want to get the from out of the "sleeping mode".
Please excuse my bad english, I hope you got me right
What do you mean by a new Display...I assume you mean a new ROM or kernel and not actually replacing the screen.
Are you using any sort of app that controls or underclocks the CPU such as SetCPU? I used that app for a while to underclock the CPU while the screen was off and it caused the sort of hanging when answering calls that you described.
Also if this is a new kernel confirm that is is not underclocking or using UV to lower the voltage.
Thank you for your reply.
I replaced the display for hardware damage reason. No new kernel or something like that.
I've done 2 hardware resets. So I just have some standard apps on my phone.
Is there some app wich dispays the voltage and frequency of the cpu?
Ok guys, the problem is "solved".
I thought, that I would have to live with my delay und phone problems forever
But this weekend, my phone decided to workl properly as before. There is no delay when bringing back the screen from sleep and no process hanging up anymore. I did not invest more energy to solve that problem.
I dont know what happened internally, but I am extremly happy now

I update my phone ICS and now from past few days there is a issue with my Note
When I turn it on from sleep screen starts flickring its like it broken down or sometings just like a TV Channel flickers due to low signal.
And then it become alright in about 15 sec automatically.
And also the in ICS the brightness of the screen through slide on the top of the screen is not working, I checked its not on auto brightness.

Thats called pixel salad, its normal in ics. This happens also to me while im in franco r4 kernel. The ics has no brightness control at the top.

[q][i9001] Low opacity screen

When my phone times out (screen turns out) i turn the screen on by pressing home button (or any other button) but sometimes the screen turns on in a very low opacity brightness, and i cant use anything, touchscreen doesnt work. I see my home desktop but in a very low opacity. Normally it goes normally bright in a minute. But it's very annoying when i want to use my phone quickly. When this happens my battery is usually under 30%.
specs: s plus
ics cyanogenmod 9
castagnait kernel
"automatic brightness" is disabled
How do i fix this? please help

Problem - sometimes screen turns on, but is dim

I've been noticing this problem intermittently and wonder if anyone else has it or if I should be concerned. Sometimes when I turn the phone on it will be dim, as if I slid the brightness bar down. If I wait it doesn't go back to normal, but if I turn off the screen and turn it back on it's suddenly normal. I'm hoping it's not a defect and doesn't become worse. It only happens 1-2x/week right now.
