blank screen but phone ON!!!! - Galaxy S I9000 Q&A, Help & Troubleshooting

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.

If I recall correctly yeah I had this issue once on JVR and once on JVS and now on JVT I got it a few hours ago

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.

FRF91 freezes 5 times daily?

What is going on here? It either freezes when:
1) slide-to-unlocking
2) switching between programs
3) google sync icon shows up in notification bar
4) in apps
Need to pull battery all the time! What's going on?
I've had this ever since the FRF50! I'm so annoyed and want to go back to 2.1, but I do love the battery life I'm getting with FRF91.
Any help please?
Sorry, realized I posted this in the wrong forum. Can MODS transfer the thread to Q&A?
I'm getting freezes on the same situations you have posted. However not with the same frequency as you. Mine is 1-2 daily.
Sent from my Nexus One using XDA App
strange, my phone is stock and ive had none of these issues, i actually thought my battery life had worsened since 91. It seems like the green meter doesnt drain as quick but the actual percentage drains faster than ever for me, at least i think so
This should unusual and should not be happening. Wipe everything and reflash.
That's Strange... I haven't had any freezes since installing the FRF91 OTA.

Yepp, same here! Never had a single freeze/lock-up since I manually updated to FRF91 from EPF21.
Hardware Issue
Seem to me you either have a defective apps or widget, a defective SD or a hardware issue like defective video ram or something like that, you could try to use a benchmark app like quadrant this may help pinpoint the exact subsystem that cause crash (video, cpu, ram) and try running stock OS with almost nothing loaded ...
This is assuming you are running from a clean install, When you have issue it's always a good idea to clean install (full wipe etc...)
Try to go to bootloader (press and hold trackball when power on), then go to recovery and clear out cache.
Mine is stock and sometimes it freeze when I tried to unlock. I had to turn the screen off and on 1-2 times to make it work again
Following your advice and let me monitor for a day or so. If doesn't work I will wipe everything and reflash.
Thanks!

wipe everything and flash both FRF91 and the latest gapps.
1. How many app you have and 2 are they on your SD? If you have alot of apps ittaking up your internal space causing you to freeze.

I actually installed spare parts the same day i installed stock frf91, so i am not sure who is the culprit. It didnt happen today, but froze yesterday and the day before.
turned off all the animations (transition/window) to get maximum speed out of my n1 using spare-parts maybe thats causing the craziness no?
Same here, 2 or 3 times per days.
I have found that cpu is burned by com.android.email ! This apps eat all cpu power when there is no wifi/data connections available and it try to sync mail...
The phone become unresponsive or very slow until connection return or I kill the app.

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

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.

any idea ?

Did you install any 3rd party app recently? What app?
How about your battery temperature? Is it hot each time after its turn off? If yes, there is probabily your facing some hardware problem (main motherboard).

after tryng several rom and check symptom collection, i had pre-analysis that maybe this is related to battery problem (or another chipset related).
dead gtab after going to sleep mode is always appear if battery < 50%.
if i try to power on again, gtab still ok and can operate until it's going to "sleep" again.
i'm going to service centre then.

[Q] Galaxy Note not waking up?

I can't put my finger on this issue I've been having with my Note.
Don't get me wrong, this device is a godsend!
The problem I've been having is that sometimes when I take my Note out of my pocket and try to press the unlock or menu button it doesn't show anything on the screen. I've read about people having issues with delay before it pops up, but it doesn't pop up even after 10 seconds or a minute, it feels like the device 'hangs' or doesn't want to wake up. The only way I can turn the phone on again is by pressing the unlock button for like 10 seconds and the phone reboots.
I thought it was a problem with Green Power, I thought it maybe had issues turning off the wifi or data when the screen was locked and that the service would cause the OS to crash or 'hang'. When I look at my battery history after the reboot it shows that I lost a significant amount of battery (5-15%, depending on how long it took for me to 'discover' the crash) and there's a 'jump' in the graph.
Things I've tried:
Stock rom - problem persists
Different kernels - tried all the kernels available in the market including stock, problem persists
Add a bit of paper between back-cover and battery (to make sure it doesn't lose contact)
Checked if there was dust between battery connections
Tried different sim card
Tried disabling wifi and data all day (mysteriously persists)
DIfferent governors (ondemand and interactive) (the phone reverts to default governor after the forced reboot, normal? i have my phone set to interactive on boot, but somehow it skips that after the forced reboot)
I've attached a picture of the battery graph. According to the stats there's a 25 minute gap where the phone was 'stuck' and you can see that the screen was on and active for that duration.
There are NO funny apps running in the background, this is is a clean install with some standard Samsung apps frozen.
tl;dr version: phone randomly won't wake up; battery loss after forced reboot;
I might have found the issue myself. Now when I come to think of it, I think it always occurs after I've been in my car for like a 30 min drive... Maybe the phone is having trouble switching networks? Anyone know what might be causing this?
Or better yet, how can I research this issue? Can I enable some logging somewhere to track this?
I had the note for about 10 days and today, about 1 hour ago it happened to me for the first time. I tried the home button to wake the screen but nothing, tried the power , nothing and holding the power but nothing happened. I had to pull the battery.
I had this problem in the beginning, but no more.
It's one of two things, in my case. Restoring apps (with data) from Titaium backup, or SetCPU or both. Do a factory reset, reinstall apps without data. If using setCPU, disable it for a while to see if it happens again. It's been over a week and the problem is gone.

I was using System Tuner instead of SetCPU to freeze apps and change governor, maybe I've just been using the wrong app? I deleted it just in case. Will see if the problem persists, thanks!
The nasty thing about it is that it seems to happen randomly (but it most likely doesn't) and is pretty rare (happens once every 3 days).
Still, I don't like the fact of not being available for X amount of time, even if it's 30 minutes.
I'm on stock room and unrooted. Like I said first time it's happened.
i've had the GNote since 4 days now , and yesterday same thing happened as the device was in my pocket and i couldnt wake it up at all , battery pull solved it.
im on stock , non rooted
I can't believe that we are the only ones with this issue. Anyone else? OR better yet, how did you resolve it?
Dont know if this is the same issue as the streak had, but with the streak if you kept it your pocket with the screen facing your body this would sometimes happen. Flipping it so that it that the screen doesnt face your body in your pocket solved this issue.

Thanks for your reply. I did some research, and apparently it had to do with static being built up in the screen from wearing it towards your body in your pocket.
This issue was that you couldn't swipe the lockscreen cause the touch screen wouldn't respond. The problem we are having is that the screen won't even turn on and that the system locks up.
Same issue here with my 2 days old Galaxy Note, that's how I found this forum. In my case it went from not waking up occasionally to every time WIFI was ON (I did some experimenting with settings to see which one could be the one causing the problem). But then...occasionally it would not wake up even with WIFI OFF: very annoying. And this is my first Android, so I didn't have any custom anything, pretty much same as out of the box when I got it The only solution was to reset the handset. And definitely has nothing to do with having it in my pocket as I don't carry it in my pocket. Rang Samsung, they told me it was faulty, I returned it. Now I'm concern the next one is going to have screen issues? As so many people complain in this forum? we'll see.
My issues have been resolved after flashing AbyssNote 1.4 and when I stopped using System Tuner. I've started using Voltage Control instead and now I'm not even having problem @ 100Mhz undervolted 50mV from stock.
Same problem with my wife's Gnote, totally stock, just a small handful of apps installed. Happened twice, about a week apart.
She does a lot of travelling, maybe you're right about that. But it happens after she gets home when it's still OK.
Had the same same issue twice in two days and had to do a battery pull, just did a master reset and re -installed the applications manually, so far so go.
YOu guys think its a hardware or a software issue?
Hmm.. Happened to me too about three times in the last two weeks. I am on stock rom but rooted, and running Green Power. Hopefully samsung will fix it in the next updates. Seems like a software bug to me. Maybe not enough juice when in deep sleep?

It's very well possible that the stock kernel has faulty settings for the CPU. Haven't had the problem again with AbyssNote 1.4 and Voltage Control (even with custom cpu frequencies)

I have this problem too. Not rooted. Probably, while charging this problem not appears.
Wrong section. This belongs in Q&A.
And for your problem, few users with.XT and XTX also reported similar problems. They are known as SoD (Sleep of Death).
There is no known fix yet. One users took it back to the store and the the Sony tech guru told him it's an isolated problem and he got a new one. So I suggest you go back to the store.
For anyone using adw launcher, one user reported that that caused his SoD. When he uninstalled that it was gone. Can be an app.
Try factory reset, and start first day without installing apps. And day by day add a new app, this way you can rule out if apps cause the problem.
Also format internal and external sdcard. Don't just empty them by wiping, you should really format, so no traces of possible app malfunction can be found back by the system.

after several days of testing, it doesnt hang on mine for 3 days already.
i guess its because there is a additional line in build prop "dalvik.vm.heapsize=36m" that cause this? this also cause my Need For Speed Most Wanted to force close too.
i also increase min clock freq to 594MHz.
also run TempMonitor(paid) on my notification bar.
not sure the above method works for most of u.. but try if it works.
I've got this problem since the first day. Got the phone, booted it up without even installing a sim card/downloading anything, plugged it into the charger, and it froze.
Since then it would go a few days without freezing, or it would freeze 3 times a day. The freezing always happen in standby mode.
Since it froze on a fresh system with no apps installed, it can't be app-related. There are users who have never experienced this problem, so I suppose the only way is to return the phone or take it to your local sony service center.
Normally it would just hang there and you'd have to pull the battery out. There was once where it hung and the phone got incredibly hot, and battery would be drained really fast.
Currently I am experimenting with keeping WiFi OFF, and surprisingly the phone has been fine for 4 days straight without freezing now. Its just something I'm trying and by no means this is a fix, but returning the phone to a sony store isn't an option for you, you might want to see if this works for you.
for those still having SOD, maybe u can try this. not sure it helps or not. because before i install jellybean, i review the code in build.prop first. so that is why it didnt happen on me for 2 weeks. well, i test it out yesterday.
use either ES file explorer or Root explorer, go to system -> build.prop.
find this line dalvik.vm.heapsize=36m, put a # in front of it to disable this code.
it could be because there is another similar code, thus conflict. u can find another similar line at the bottom of build.prop.
hope it helps!
Have you had anymore sod since disabling that?
