No idea... I bought my phone at the earlier earlier batch, where it is pack in bubblewrap... LOL!
Anyway, at 2.2.2, still same problem. Doesn't want to get custom rom, as after my exam, i'm going down to LG and get some servicing or shyt out from them...
The problem exist especially when you are charging. It occur also when you put your phone to sleep while running on GPS. Very fedup with it.

It is categorized in Freeze and Reboot Problem
It's the first stage of that problem, if you continue using it, you will suffer the reboot problem

solution to some bsod models. Tested, working!
Many p990 bsod models have faulty soldering of some sort. A solution which have worked for many is to simply plug in your charger. When your phone goes to sleep and doesnt wake up when you hit the power button, just leave it be for 12+ hours. Place your phone on something soft as well, like your bed. This will heat up the device and fix the faulty soldering. If it does not work, try longer period of charging. Good luck. (I will take no responsibility if this does not work as planned)
This was tried on a bsod model which went to unresponsive sleep every 5-30 minutes. After this procedure it was faultless

have u tried not to sleep your device when charge?? settings->applications->development->stay awake

I've had my LG for quite some time now and I still trying to figure it out. So, if you're patient enough, please, just bare with me for a while as I explain what I've tried so far what what were the results.
A lot of people complains about this phone... unstable, crashes, reboots, BSOD, etc...
The first problem I had, came with the stock ROM... after a while the Wi-Fi just stopped working and it would display "Error..." as a message. The only solution was to reboot. 3 or 4 days after I had bought it, this was already killing me... so I started trying other ROMs but all seemed to suffer from some sort of problem except for one (see phone info below), which I've been running since June and I find it impeccably stable I can basically keep my phone running for as long as I want, as long as the battery doesn't run out (obviously), which brings me to a second point... battery drain!!
The battery drain was the only problem I didn't manage to find a solution for... and after a certain while, even though my phone was stable, having to charge my phone every single day was becoming very annoying.
Since I live in a different country than my GSM operator, it doesn't come as a news flash that network look-up has a big impact on the battery life, specially because I live close enough to the border to be able to keep the signal but in some parts of my house the signal is lost forcing the phone to search for a new network, which sometimes it finds (roaming) and sometimes it comes back to the original network and so on... However, what I find, unarguably, to have the biggest impact on the battery is having the Wi-fi enabled when there's no available network, it's just huge, it can suck up the battery in a few hours...
So, I decided to try some of those power management apps such as Locale, Green Power and some other, in order to minimize these problems, but curiously, they all caused the same problem... BSOD within a matter of minutes. I installed the app, configured it, waited for the phone to go into sleep and puff... it was gone. The only way out of it was removing the battery. I uninstalled the app, and the phone was stable again... this happened with every single app of the kind, that I have tried.
At the moment my phone is as stable as it gets but if I don't pay it enough attention, the battery dies in a blink of an eye.
Model number: LG-P990

WIFI sleep policy on CM7

Hey guys,
ever since I used CM7 on my Galaxy it puts the WIFI in sleep mode as soon as i turn the screen off. I've set the sleep policy to never but yet it slows the datarate down first and then some seconds later it is stuck at 0 kb/s. That's very annoying especially if you download some bigger files. Is that a known bug on CM7 or is it just me?

Come on, i am the only one with that problem? :/

I don't have this problem, download continues even if the screen is locked...

When I was using CM7 a while back I had this same issue. Had to make sure screen was on all the time. This and some other small issues made me switch back to Darky's ROM which lags like crazy, but at least has good battery life and is stable.

Are you sure? Even same speed as with screen turned on? How in the blue does it work for you? I've had this issue on every nightly so far

Ever tried another modem/kernel?

I've tried several modems. Currently i'm on JVQ... As kernel I only tried Fugumod so far... but i seems like it works for others :/
@mobidzid
I've tried this and other apps who keep connection alive, but they have no effect at all for me :/

I have the opposite for MIUI rom.
The MIUI rom by default set the WIFI in sleep mode as soon as the screen is turned off. However, from the battery history, the WIFI never go to sleep. Is this a problem with MIUI rom or there are other setting required?

Nothing new on this? It really drives me crazy here

Please delete, I wrote into the wrong thread... :O

I have same problem?! If anyone solved problem?

blank screen but phone ON!!!!

Has anyone had this issue?
I have tried a few different ROM's and have had this problem on all, the phone will work but sometimes when the phone is locked and asleep you cannot get the screen back.
If you ring the phone it will ring but you can't wake the phone up (the screen is off).
If I then pull the battery and reboot all is well until the next time, which is random.
I will remove all my programs to see if there is one of them causing the issue, I don't believe it is the rom as it has happened on a few of them.

Have you wiped your phone when flashing the different roms? I've had it sometimes, i think it could be a ram management issue...

Yeh, I always do a factory/wipe, dalvik cache wipe.
I think it might have been TW4.5, I did some research and installed TW4 Manager I then updated TW4.5 to the latest Version. So far it hasn't happened yet but i'll give it a couple more days.
Thanks.

Yh ive been reading and TW4 generally accelerates the issue (because its a ram hog? not sure i dont use it) Im currently using Golauncher with system tweaks, but was told that nemus launcher and system tweaks was a better combination... Seems to be working, ive had less force closes or issues of that type

it's the proximity sensor. needs replaced.

I don't think so...
The proximity sensor is only used when your in a call. It should not have any effect when he tries to wake it from his pocket after a while...

Well i am on 2.3.5 and using golauncher and never had any problems. Still my best guess is the damn sensor. On samsung apps there is an app called sensors i think and that app tells u what is working inside the phone.

Sounds like a great app but seeing as the screen doesn't turn on that app might as well be useless in this case

No screen turns on, its just when it turns off it wont come back on...

I have the same issue with my SGS. Running stock version of JVT.
Wake up in the morning to phone alarm but screen is black. Pushing home button or any other button does nothing. Had this happen a few times now and only solution is to pull the battery

In order to help you we need to know what you are running currently and what you have tried to resolve the issue so far, can please make as detailed account as possible

It's seems that everybody have this same issue. I have exactly this same - phone is working - buttons are lit, but the screen is blank. I'm on 2.3.5 stock firmware.
Trying to solve this I already did wipe and even formatted the internal storage.
What's more interesting is that this same happens to my wife's Galaxy Mini (S5570) !!.
I can remember though that when my phone was on v2.2 about a year ago it was working ok.
small tip:
What you can do instead of pulling the battery out is to press the power button for about 10 seconds ( phone will turn off) release and the press it again for few seconds to start again.

You don`t need to press power again, just keep it pressed until you see the samsung bootlogo.
Mine has started to blackout too, maybe it`s related to some installed software. It worked ok still few months ago. My galaxy mini is working ok tho, has only few market apps installed.

The bug is called SOD (Sleep of Death). Apparently a Gingerbread only bug (I think deep sleep was introduced in Gingerbread).
Your phone is going into deep sleep, and can't be woken agian.
I don't know if there is a fix for it, but you could try search for SOD on these forum pages.

i had this issue on cm7 with neo kernel, but sometimes it responded after some time
i think its black magic made by apple and will kill our cats

As Herman76 said, this is the SOD, I used to get them quite frequently. I created a thread with a possible workaround. So far haven't got any new SODs.

Timer function problem after Gingerbread update!

As the title states, im having problems with the timer function after the update.
Before i could set the timer and let it run in the background while the screen is off.
But now, as soon as i press the power-button and the screen goes blank, the timer stoppes! This is really bugging me since its a function a use alot.
Anybody has any ideas as to why this happens? Can you test and report back to me if you are noticing the same?
Thx!
*Edit*
The timer actually resets when i hit the home button and the screen is turned off using the power-button. It resumes from start again when i re-enter the timer. Is this how it should be?

Sounds like a VT_ALARM signal

@mh1337
Im sorry.
I dont quite understand what you mean?

Once again my timer got reset.
I had the timer going, and i recieved a call. When i returned to check the timer, it had reset to start, but was counting down.
The button under the time said start, even though the timer was running. So this seems like a bug to me. Any thoughts?

I get the same issue on mine. I'm running GB as well. 2.2 was fine.

Thank you for reporting in. "Glad" to hear im not the only one with the problem.
This is the the third thing the GB updage has damaged for me. 1 is the battery time (lost about 10 hours) 2 is gps issu, and 3 is the timer problem..

Not that it's any help to you, but this is not happening with v20G (UK open).

Okei.
Have you had any other problems? Gps problems, battery problems after GB update?
Im trying to figure out if there is a connection between the bugs im now facing after the GB update. Cause everything worket fine before.

The battery seems slightly better if anything, but I can't be sure on that as I only updated yesterday.
Will try the GPS out and let you know, as I'm out and about a bit later on today.

GPS took around 30 seconds to get a lock while outside, which is slower than it was on 2.2, but when it did get a lock it was accurate and remained so as I walked into my local town.

I'd reinstall the kernel selecting the default freq for each setting. Going too low will cause this problem. I wouldn't use setcpu or any othe profiler as the kernel is customizable enough to select what you need when you install it. This presumes you're s-off of course.
