weird screen behavior on cm7 and miui - Fascinate General

Noticed something weird with my fassy this week, the screen was waking up itself randomly. At the time I was on the latest build of cm7. It got so bad I would hit the power button to shut off the screen and it would pop right back on to the lockscreen. So I wiped the phone and flashed the Miui rom. EXACT same behavior! So I odined back to DL09, then to Froyo, then reflashed cm7. Incredibly the phone still does this so I dove into the settings today, didn't find much but I did stumble onto a solution........its only does it when I have data turned on (I mostly keep it off during the week because my work has horrible reception and my battery will go dead in about 4 hours) .Whats weird is its completely random, sometimes I will spend 10 minutes to turn the screen off (it keeps popping back on), other times it doesn't have this problem. If i turn data off there are no problems.

I'm not sure if I'm right, but people seem to be having weird bugs appear in 3G low-signal areas, including random button presses and other weird behavior with CM7/MIUI. Maybe this is related to your problem? Does this happen in all areas or in low-signal areas only?

Might be the reason, it does seem to happen in low signal areas that's an interesting theory.

i've been on CM7 for a couple weeks and haven't noticed this problem, but interestingly i used to get it when i was using stock roms that were just debloated. i would notice my phone would randomly wake the screen to full brightness on it's own, decrease and then shut back off in a span of probably 15 seconds.

I'm thinking that might be the reason, and when you turn off data you're disabling the weak 3G signal, preventing the bug from happening. For now, I believe no fix is available.
And as far as this being related to the stock ROMs, I believe that was a completely different issue. This is related to 3G signal strength. I've haven't seen this bug yet since I live in a coverage-saturated area, but the reason I know about this is that other people have been complaining about it in the CM7/MIUI threads.

G1 Doesnt Always Wake Up

Does anyone elses G1 not wake up when Menu is pressed? Sometimes I have to press it like 6 times before the phone wakes up, does anyone know why?
Mine does this as well. I just thought it was learning from it's owner (I take more than 5-6 pokes to wake me up too).
My only guess is that something is running in the background in order to slow it down and the number of presses has little to do with it.

Yea, i was thinkin the same, i should try runnin a ton of apps and find out if [email protected] the problem
mine does the same things sometimes. gets annoying at times. usually i just open and close the keyboard
Mine recently started this, it must be something we downloaded, plus I have the following problems too, they all started at the same time:
1) When someone calls, the screen stay blank for a while so the phone rings but the screen is off so I dont see whos calling
2) The background keeps changing back to the original blue picture thing
3) The WiFi keeps turning off and drians the battery, nothing I do stops it from turning on. I have all sorts of software running, I even ask Locale to turn it off if its between 12.01am to 11pm and still WiFi keeps poping up.
4) Battery drains FAST lately.
I uninstalled a long list of software and problem is not solved.

Shop Savvy?
I also started having the wake up problem and quicker then normal battery drain. I have an ADP1 phone which I updated to 1.1 a few days before noticing issue
I think that the theory of something sucking clock cycles is a good one. I noticed my CPU Usage (when nothing was running other then System Monitor) went from 0-40% to 20-70%.
I couldn't be bothered with the finer points of troubleshooting, so I took the thermo-nuclear approach and did a factory wipe.
Just before the mystery CPU cycle and wake up issue, I hadn't installed any new apps, BUT I did update a bunch of existing apps. After the factory wipe, I left off installing the following list:
Watts
StreamFurious
DroidFTP
Telnet
e-VoiceRecorder
VoiceRecorder
Constitution
Barcode Scanner
Astro
RingDroid
SlovoEd Classic English Dictionary
Things are fine now.
both of my g1's do this, and have done this out of the box, anyone turn off there screen with the keyboard out, and then close the screen and the screen comes back on with the lock screen up and then having to turn the screen back off? annoying
try the swapper app?
or turn phone off and back on, it might becuase you are usingahome or openhome or dxtop or sweeterhome, these app may slow down the interface a bit, try downloading droid sans tweak lite and fool around with that..
goodluck i also get this sometimes

I'm having same issue as the OP and issued #1, 3 and 4 from the above post.
Hmm, im not experiencing any of the above posted issues, it may be a particular app that u have installed. I only have the wakeup issue sometimes, most likely when the phone is running slow from the browser or another memory draining app, but no app in particular.
Hmm, when mine fails to wake up, I never waited long enough for it to come back, just reseated the battery for a reboot.
Of the other problems, I have the "screen-black-for-a-few-before-caller-picture-shows-up" issue.

what firmware do you have?
btw, dont count on Locale to turn off your stuff all the time, its not very accurate imo, at times its great, but thanks to the crappy g1 battery, they have a choice, constantly check time/location/.ect and drain the battery in a hour flat, or periodically check it and reduce battery drain, do you have any wifi programs that keep wifi on when phone sleeps (such as wifi lock and so on)? if so use the program on the market that writes up a log of its actions and see if its acting up
as for #1 (sorry im unorganized) my phone does that too, i believe its because i have 2 programs that run when the phone rings, let alone im sure locale is checking to see who is coming since thats a condition, which would make 3, and then i have a mp3 that plays when the phone rings, and i have a class 4 sd card (i know, i know), the way that programs work is that it has to go line by line of the code, if it is slowed down, or it has to execute other items before continuing that are slow to execute, than everything has a delay, but yeah from time to time i have this issue, phoneplus was a program that made me miss a few calls (1/4th of the time)
i think 3 and 4 are directly related, could be wrong
I was having the same problem right after I installed the app "Contact Owner"
No amount of reboots fixed the problem. Uninstalled and everything was back to normal.

consider upgrading to the rc33 ota update yet? i had better battery life (and my battery didnt get as hot) when i used rc33
also, if youve had your phone since it first came out (rc19 i believe) and your battery used to get very hot, you might of damaged some of the cells (especially of the battery has expanded), if this is the case simply call tmobile and tell them that your noticing even after wiping the phone that your battery life is lasting shorter and shorted, even with out any programs installed from the market, i even went as far as to say that i made sure wifi was off, only 2g was on, gps was off, screen was dimmed, timeout set at 30 secs, and im still only getting a hour of life (none of which is true but it got through all the "well how about trying this and calling back if you still have a problem" bs, with the ota rc33 and the new battery, i noticed a pretty good difference
I have a modified version of this "doesnt always wake up". The phone is less than 24 hours old, it was a refurb they sent me for the last one that went dead. I used it with the rc33 it came with and found the problem, then figured it was hosed so i rooted and installed 3 of the versions of cupcake (The Dude, JF, and Haykuro) to see if they all had the issue- they do. Here is a video, hope you can see the attempted keypresses. There will be lines that appear, like the screen is broke..then, they will go away. Sometimes it takes 5 minutes to get the phone to turn on, however if I leave it on (never goes to sleep) it works flawlessly.
http://www.youtube.com/watch?v=ecQo2Ly2WUM
I get this all the time also...
Uninstalling dxTop doesn't change anything for me...it still acts the same...
I also get the problem that when someone calls me the screen stays blank for about 5 seconds and I can't tell who calling...
wake up issue
I am experiencing the same problem, with a brand new warranty replaced G1, what happens is when the phone goes to sleep it completely locks up, when I try to wake it up via menu, it does not wake. Plugging the phone in and trying ddms or adb does not work, ddms shows the phone as offline, also the device seems to get really hot when this happens, sometimes Call + Menu + Power resets it, and sometimes I have to pull the battery.
I think this may have to do with wifi turned on. Because when the screen goes off your phone switches wifi off and goes to 3G as default setting.
I think we should try leaving wifi on all the time and see if that solves the issue, im about to try that now.
It seems this is a known issue over at tmo forums
A couple questions:
When this happens to you guys is wifi enabled and connected when the phone is shut off?
What Rom, SPL, and Radio is installed?
I noticed this didnt happen to me until I enabled wifi, maybe I didnt wait long enough because its completely random, please send back your results

Issues since updating my Bravo

I would like to start this out by saying that I have had my Bravo since January 16, and have loved every minute of it. This has been my first Android (Came over from my iPhone 3G). I was extremely excited to finally get the upgrade to 2.2, even though I decided to wait to officially download it OTA.
Since I got my phone, I had no more than three to five apps force close on my using the stock launcher. I rarely noticed much of any lag while working with my phone, and I never once had any issues with the phone rebooting itself on me.
Since I updated my phone on Saturday I've been plagued with all of these issues. Immediately after updating, I noticed my phone was running very hot, and my battery drained to 50% within an hour or two without me even running anything stressful on it. I restarted it twice and since then I haven't noticed any significant issues with my battery, or the phone seeming to run it's processor excessively.
But, I have constant lag, making tasks that were extremely quick and easy before the weekend be significantly more difficult and frustrating. Today I've even noticed that the lag is so bad that I am not even able to use Swype because the phone takes so long to register any touch's it doesn't register anything other than the first and last letter I swyped across. In addition, my phone has rebooted itself 3 times within the last three days I've been using it, an issue that has not happened once in the three months before this weekend.
I will regularly be trying to do things on my phone and it will lag, causing the phone to freeze for 20-30 seconds at a time, and then trying to perform every touch it received in those 20-30 seconds in a scant second after it recovers.
I have noticed some issues not regarding lag, but sometimes it has been difficult for my phone to initiate calls. I have tried to call my wife, and it took 5 times before the call would finally go through, it was immediately ending the call right after I pressed the call button.
I love my phone and the capabilities of the Android system. Until now I haven't had any problems at all with it. Can you help me try to figure out what's happening, and if there are any ways to fix my phone? I haven't gotten around to rooting my phone since I've gotten it, but have been planning on it.

Something probably is messed up in the upgrade process.
Simple solution, flash the 2.2 sbf and you should be good.
roadkizzle, Something doesn't sound right at all with your update. I would try to remove the battery for a minute and reboot. If you still have issues I would try a factory data reset. If that doesn't cure your ills then flashing the 2.2sbf as bandroidx suggested may be in order.
Alright, I flashed the SBF file to the phone through RSDLite, and from what I can see it went through correctly. My only question now is do you think I'll need to try to re-install the full update? Or is that similar to what I did?

flashing the sbf already updated your phone to 2.2. You don't need to do anything else
I hope reflashing did the trick for you. That experience sounds nasty...

Well, after a couple of hours of playing with my phone it's seeming better. I have been playing a few games of Worms, and my normal surfing the internet and so far I haven't noticed any real lag. The test will be my day through tomorrow.
I was just really confused because I was following the instructions from the Flashing SPRecovery SBF to a Motorola Droid youtube video, and his SBF file really seemed to only change the recovery screen. It looked like he still had to go through the actual update.zip process to make the actual updates to his phone.
Alright it's official, flashing the sbf did not fix the lag issues. My phone hasn't had a critical malfunction and reboot itself yet today, but the lag is unbearable.
roadkizzle, It sounds like you are still having issues. If you look at the system version in "about phone" in settings menu does it say version 37.4.0.MB520??
Yes, it says Version.37.4.0.MB520.ATT.en.US

what apps do you have installed?
look in task master and get rid of any auto-ends and reboot and see if that makes a difference
Well, immediately after removing the AT&T apps from the auto-end list and rebooting, I thought I noticed some lag initially, but I've let it run for a few days now doing everything I was before and I've not been having any of those issues recently.
I'm not sure what it was. I wasn't very aggressive adding apps to my auto-end list, really just Maps and the AT&T apps. I added maps after a while because when I would use it once it would stay open and I'd notice later on that it would have been a major consumer of my battery, and I couldn't figure out how to close it fully.
Glad to hear things are going better. I had some issues totally unrelated to the apps I had in auto-end but pulling all of them off of auto-end got rid of the issues. Froyo is supposed to minimise the need for having to add apps to auto-end in task manager. Regards
(SIA for the long post)
roadkizzle - my situation sounds very similar to yours and I wanted see if you are also seeing a couple of other symptoms I've seen beyond what you have indicated. This has been an issue from early on for me. At first it seemed to be associated to when the battery was low, but it is now ever increasingly interrupting my use of the phone. I was hoping 2.2 might resolve some of this, but it hasn't.
Background: Purchased/activated phone early Jan 2011; recently upgraded to the 2.2 sys and used the official channels; all apps I've added are lightweight stuff (ex: notepad-type stuff, weather widget) and I have pushed most unused stuff to the auto-end list.
Similar symptoms: I see the same power drain and high CPU usage when using maps/navigator (really evident on a recent trip). Still monitoring if some of that can be attributed to use of the GPS.
I'm getting a similar lag though I wish it was only for the short period you are seeing. I've only rarely been able to just put the phone down and have it responsive when I get back to it. Maps/Navigator were especially susceptible to this problem, and it seemed consistent with the 90%+ CPU usage often seen when they are running.
I don't use swipe, but the keypad is most often what is being used when the lag kicks in... the entire phone just goes completely unresponsive, including any and all other input such as the hardware home/back keys, etc.
In addition: Better than half the time that the qwerty touchpad becomes unresponsive, I see sporadically entered random keystrokes to my messages... everything from initiating the voice input to entering several dozen spaces or just simple random characters. This happens at a random, often changing rate and I see the keys lighting up and the haptic responses happen as if I were touching the keys, but they are not from any delay in the input. Once ruling out an exorcism, this has started me thinking I might have a hardware issue with the touchpad. The phone has not been dropped or roughed up in any way, so if it is HDWR, it's a manuf issue.
Luckily.... in 99% of the cases where this happens, using the HDWR power button to cycle the screen through a sleep and back resolves the issue. Not a big deal unless you have to do it 3 times to send one text/mail. This has me constantly thinking about items on the auto-end list but I have not unearthed anything to support that.
The other 1% of the time I have had to reboot the phone, but in those cases I can't rule out 'user issues' due to just pure frustration. Task Manager has become my most freq used app, but often I see everything at 0% CPU and/or not running.
I'm wondering if any of these additional symptoms sound familiar...
thx.

Try taking things off of the auto-end list. You shouldn't need the task killer because android manages apps on its own (it's supposed to manage apps better in froyo than in 2.1)
I've also had lag, especially when opening maps (the first time I open maps it often force closes).
Can anyone get the "lock pattern" screen without the slide to unlock? It seems like a common "Motorola 2.2" issue, but I can't figure out if it gets resolved through an update or not

[Q] Nexus 7 screen turning itself on?

Hi all,
I'm experiencing an issue on my stock 4.1.1 Nexus 7. The screen seems to be turning itself on randomly. It normally turns off again but may toggle on/off quite a few times. Then it seems to go for a while whitout turning on. Bit odd.
Anyone else experienced this or have any thoughts on a reason for it?
Thanks
Same problem here, except with a Samsung Galaxy Nexus.
I just updated to 4.1.1 today and this is the first time I've seen it happen. Was previously on 4.02 without issues.
I have had the same problem. It seems to happen in the evening and I wondered whether the case was causing it to overheat. Seems to be OK when I take it out of the case. I phoned Google and was told that it hadn't happened before. I will contact them again if it doesn't get any better.
Sorry. Misread the post. Mine goes to sleep, not turns on

Same here but mine is not exactly stock.
I have installed Apex Launcher plus numerous apps. I thought maybe it was the launcher doing it. But at this point... I have no idea. Just noticed it tonight coming on and then going off within 1 sec. but its random. it may do it once within an hour, or it may do it up to 5 times within a min... then go several minutes completely black screen. Crazy stuff. I thought maybe it was getting a message at first but then realized I had the WiFi off on my phone so it was dead to any incoming messages/wifi. I am really curious as to what is causing it and will be following this post as well as others quite frequent. Also.... the latest app that I have downloaded was OSMOS HD. it wasn't waking then sleeping before that app... just my 2 cents.
Hi Qbensis,
By stock, I just mean not rooted and not running any custom firmware. I had various apps and the like installed.
I have actually since rooted my N7 and installed a few custom ROMs and since then have not seen the issue at all. If you want to stay stock, I assume the issue will be fixed in the next update
I have seen this a few times. Middle of the night I look over and the screen is on then off. I check the power usage overnight and I see little blips of screen on when looking at the graph. Not sure whats causing it (I figure a app).
Same Problem over here, any solutions???
I'm on stock 4.1.2 and having the same problem, not rooted. Creeped me out in the middle of the night when it goes on and off.
N7 Random Turn On
Same here on 4.2.1. I carry in front pocket all the time with screen facing leg and feel heat when it happens. Has even done it when in Power Off mode and still does it. I thought that would prevent it for sure. Very irritating and drains battery. We Winter in 55+ community and drive around in golf carts. I am starting to wonder if WiFi spots trigger it. Will continue to track behavior and search other forums. Curious that there have not been any solid suggestions or solutions.
Happens to my rooted but stock 4.2.1. It happens randomly when I recharge using a battery pack (4AA) as opposed to charging using regular AC. It's annoying as heck! I don't know how to get this fixed!
I've been getting this on both SmoothROM and raspbeanjelly, and it's very irritating.
It has to be an app that is causing this. I initially thought perhaps it was GPS Status, because I caught it in the notification bar a few times when the screen turned on.
My device definitely isn't hot when it happens.
I'm suspecting the Email app, Maps, or Facebook.
EDIT - not any of them either. I'll test Beautiful Widgets next.
Okay guys, try this.
http://forum.xda-developers.com/showpost.php?p=29420959&postcount=7059
I'd been suffering from this for weeks, factory reset, reinstalled and changed out ROMs, installed apps one by one over the course of several days to keep an eye on what might be triggering it etc. Nothing worked for more than 2-3 days at most, and the issue always came back in one way or another.
It was causing me to have to turn the Nexus off when not in use because it would be draining battery (15-20% overnight compared to 2-3% when the issue wasn't present).
Then I stumbled upon that guide and using Gemini I disabled Maps from auto-running, turned off Latitude, and so far so good.
If it works for you too, be sure to hit thanks on Karpfenhai's post!
I was having this same problem on my Nexus 7 running stock 4.2.2 rooted with SuperSU. Finally tracked it down to having installed BetterBatteryStats and for some reason, I had not granted it perpetual root. It was causing the device to wake and turn the display on for random times (up to 13 hours, which killed the battery), not always showing the SU request dialogue. I granted perpetual SU privilege to BetterBatteryStats and problem went away.
Try taking out the battery and clean out the USB port with a toothpick. This worked for me. All the dust that accumulates in the post can cause the phone to think it's charging.

[Q] Nexus 7 Crash/Reboot

Hi, I've seen this around a bit and just wanted a little bit more information, if any one has it.
Basically, a few weeks ago, I had a random shutdown, and had to do the 30 sec+ powerhold to boot it back up (NOT NORMAL FOR MY DEVICE USUALLY AROUND 3/5 Seconds ! )
I only knew to do that because of XDA so +1 there people !
Then, a couple of nights ago, was browsing around Chrome etc, and BOOM first CRASH EVER ! with my nexus devices, and to be honest, I thought crashes were a thing of the past/desktop laptop specific, as my HOX has never crashed. I WAS GUTTED
So I did the power thing, and it booted.
Again last night, another crash and shutdown, then 30 sec + power hold to boot again.
Basically, I want to know is this a sign of a deteriating device? Is there a known cause? Should I be worried?
Is there anything specific I could have on my tablet causing it?
I have over 10GB space still left on my 16GB device, as I'm rather a ****** when it comes to filling devices (i tend not to download much, other than REALLY useful apps TO ME ! like XDA, Flipboard and a few random games.
Any information would deeply be appreciated.
Anyone?
I had this for a while, and discovered the cause was that I'd disconnected the ground pin on my Wifi antenna in order to stop low screen brightness flicker. Removing the bit of tape stopped the reboots.
If you haven't done this mod, then I'd suggest it may be to do with weak wifi signal? Maybe the spring pins aren't making solid contact with the antenna?

Nah I havent even touched my Nexus 7 in that way.
Its not been opened or tampered with
And if your being serious about a dodgey wifi antenna spring within the Nexus 7 im gonna end up killing someone, as my HOX has the Wifi antenna fault to.!!!
Can I just ask, how would a weak wifi signal cause the unit to crash and reboot?
THANKS!
It was just a thought based on my experience of effectively semi disabling the antenna, I've no specific knowledge to tie a crash to wifi signal strength, so pure conjecture.
Perhaps an intermittent connection confuses the logic and crashes the device?

Hi, dya know mate I've just thought of something and you could be on to something, not necessarily a weak signal, but Im sure its network based, as the second time round (cant remember what I was doing first time) I was switching between browsers, Incognito etc.(Opera/Google)
This started happening to my N7 starting a few days ago. I wasn't necessarily using Chrome but was on the Play Store updating apps or on Bacon Reader and it would crash and reboot.
I haven't opened up my N7 but have rooted.
I see this all the time
I'm seeing this on both my Nexus 7, and my Galaxy Nexus. A friend of mine is seeing it on her phone as well (I forget the model, but different than mine and also running Jellybean).
It seems to happen when I have poor wifi (e.g. the wifi meter on the N7 switches from blue to grey). The typical behavior is that some app mostly locks up. At first, the soft menu buttons still give feedback that they've been pushed, but don't do anything. The device can usually be turned off with a tap of the power button, but won't come back on again with a second tap.
After a delay, the device will display the multicolored "X" that indicates it's rebooting.
This happens 2 - 6 times per day on each of my devices right now. It's *very* frustrating.
I've been thinking of doing a factor reset to see if that helps, but haven't yet.
Any other suggestions?

First Freeze Issue after JB 4.12 update on GN 8013

I just had a scare. I updated my GN 8013 to JB 4.12 several days ago and haven't had any real issues. I let my Note go into hibernate to take a break and do some chores in between trying to finish an ebook checked out from my local library. The battery was at 68 per cent and I planned to be back to reading within 10 minutes. When I did get back to read and picked up my Note it wouldn't turn on. This is the first time this has happened. Jumping onto Google, it appears this has happened to other Samsung tablets in the past, usually after a software update. Here's a link I used and following the steps outlined in I then was able to reboot (keep finger on screen while holding down power button then reboot once battery icon appears on screen). http://mojocode.com/content/samsung-galaxy-tablet-101s-wont-boot My battery is still at 68 percent, but I'm leaving it plugged in while I do some other chores. I hope this isn't a new problem brought about by the update. If anyone else has this issue, I'd suggest we keep track so we can report to Samsung.
Yeah I think they call it the sleep of death. Happened to my recently updated wifi (8013)note also.
IF it is happening then only 8013 devices as none from other devices have reported so far. If two devices then it is a cause of worry

I started the thread so we can see if it's happening to multiple units and what models and firmare seem to be affected. If more report the same issue, maybe this thread can be stickied. From what I read when looking for solutions, it seems to occur after firmware updates and has occurred on many of Samsung's tablets.
I have a N8000 and it's happened to mine three or four times since August; once on ICS. It would infrequently happen to my GT-P7500 on HC also. You can be in the middle of something and the screen goes black. No warnings or pop-ups, it just goes black. Nothing happens when you hit the power button normally like you would to wake it up. You have to hold the power button down for a looong time (maybe more than once) and the tablet boots. The first time it happens it's stroke inducing because you think your tablet's dead. After that it's just an annoyance. I have no idea what causes it but it does no harm (other than potentially losing unsaved work) when it happens. Between my OG G-Tab and the Note it's probably happened half a dozen times in eighteen months.

On my GN 8013, I had to keep a finger on my screen while holding down the power button; that brought up the battery icon screen and from there I could reboot. Holding down the power button alone did not reboot and triggered my panic that drove me to a Google search and a solution to enable rebooting. This seems to be a long standing issue across versions of Android and manufacturers and seems to be a result of manufacturer code tweaking having unexpected consequences.

I kind of look at it as the equivalent of the "blue screen of death" in Windows. My desktop PC throws a shoe every once in a while and it's usually tied to either graphics or memory conflicts based on the dump message. I'm guessing what we're experiencing is the Android version. As a pure guess I'd say it's something to do with memory reads/writes/buffers caused by either a management issue with the OS or an app (or combination of apps) doing something it shouldn't at an inappropriate time. And after playing with the power button I've gotten what you did (the giant battery icon showing up) and other times the Samsung boot logo. And I've had it happen twice in a week and other times once in six months; all without changing anything with the OS or apps. It's just one of life's little mysteries.
P.S. - My N2's done it but it behaves differently. It shows up a spontaneous reboot.
I had same issue frequently since last upgrade to 4.1.2 . I thought the problem is from Mobile VOIP. So I un installed it.
But today, another freeze happened. Ok, today just once. But, what's the problem?
N.b I recover it just by holding power button for 8 seconds.

If it's happening frequently it may be something other than the random event some of us are talking about. A lot of you that upgraded from ICS to JB with all your apps intact could be having compatibility issues as not all apps have been updated/optimized yet. Older apps that are a little less mainstream and/or popular would be a good place to start to troubleshoot. Unless there's something specific to U.S. JB a lot of us have been on it since October and there haven't been any reports of frequent freezes or reboots. That is outside the random one discussed above that's not specific to JB.

Pretty much exact same thing happened to me last night, for the first time ever. Took me about 30 seconds to get any response, by holding down the power button for a LONG time. Rebooted, saw the battery was below 20%, which was also odd since I had charged it overnight and had consistently been getting 2-3 days on a charge.
If it happens again, I'll go with Barry's suggestion and try a clean install, then adding apps one by one. Little disappointing though, as I've had no real problems at all with the GNote until this JB update.
Thanks,
JC
Sleep of Death...
I have the 16gb wifi GT8013 model and I am having the sleep issue too. Mine isn't "deathly" that requires the finger on the screen while powering up, or standing on your head and spinning three times while chanting "sleep of death" or any craziness like that, but every once and a while, for no rhyme or reason, I have to start it from a cold boot when I attempt to wake it with the power button. I press and hold the power button for 3-4 seconds and here comes the Samsung boot logo. Once it gets booted and connects to the wifi, I am good to go.
This happens so intermittently, with it not doing it for a couple days, or it might be within the next hour. I think I have narrowed it down to the wifi radio. Reason being...I have done a factory reset and tried running it naked and it still happened. But I have noticed the issue seems to happen when I have left the house and it drops the home wifi and then negotiates a new connection with my SIII hotspot, which I turn on before leaving the house for work, or anything that I will need connectivity for the tablet while away from the house. I don't know if it is due to roaming outside the home wife and dropping the connection, or if it is the combination of dropping the home wifi and then locking into the phone hotspot. I am so busy that I haven't been able to get that far in my troubleshooting. However, I am leaning to just the fact of it leaving a wifi signal and, I guess, it doesn't want to and gets jumbled and kills itself all together. I say that because it has happened when I have forgotten to turn on the hotspot until I got to work and then I open the tablet and its dead.
This has been happening from day one, when I bought the tablet towards the end of January. Unfortunately the Samsung warranty absolutely sucks, due to them wanting me to ship it in and do without it for 3wks and then to boil my blood even more, they want to give me a refurb unit if they can't fix this one. To make matters worse, its been almost a week now and they can't even get the shipping arrangements made yet! Needless to say, with this thing only being barely two months old, I am a little on edge with Samsung and I would love to figure it out and fix it myself. If it were something I knew, without a doubt, would be fixed with rooting and dropping CM on there, then I would. But I see there are still stability issues with most custom ROMs and I really would like to keep the functionality of the S-pen.
I have attempted to pull a log file with aLogCat and they are blank. It appears that the log files disappear when rebooted, which does me no good in figuring out what shut it down, if I can't recall the log from pre-shutdown. I have also tried aLogrec in hopes of accomplishing this, however, something isn't right because I left it recording for hours and days and the log file was only 1kb. Although, it doesn't much matter since the log recorder running in the background keeps it from sleeping to the point of shutdown, so I am assuming it is a sleep issue, due to that discovery.
If anyone has any thoughts that might help me, I am definitely all ears! This tablet is for work and school so it is next to impossible for me to do without it for 3wks...provided Samsung can get their crap in gear enough to even arrange the shipping for the service request. And I sure as hell don't want a refurb!!
Later,

I had periodic issues with the sleep-of-death once I updated to JB. It turned out that a VOIP program that worked fine on ICS (Sipdroid) crashed JB. I installed a different VOIP program that users said worked with JB (C-SipSimple) and my tablet stabilized. If you have non-stock apps that you use a lot, I would begin doing Google searches on them, starting with those that you use most frequently to see if anyone is reporting issues with JB (I wouldn't only rely on comments in playstore since users are more likely to engage in a discussin in a forum like this one). Good luck.

Unfortunately, I have come to the conclusion it isn't an app issue. I have never used any VOIP service, of any kind, and I have done a factory reset and it happened before I installed any apps. Unless, of course, it is an app or service that is included in the Touchwiz junk and/or bloatware that comes with it. It happened on ICS, which is what came on it, and it happens after being update to JB. However, I only had it on ICS for a couple days and I would like to go back to it for further troubleshooting, but since it has been updated to JB, that isn't possible without rooting and I haven't decided if I want to do that yet.

After further observation, it appears my sleep-of-death issues arise when I leave the comforts of my home Wifi. When doing so, apparently losing the Wifi signal causes the tablet to shut down completely... When asleep. If I have LogCatRec running, that keeps the tablet from falling into hibernate and the issue never happens, thus resulting in nothing interesting being logged, aside from the typical tablet activity.
Now the question arises, is it my home Wifi, or just leaving a Wifi range in general? I cannot get it to recreate the issue by simply turning off the Wifi signal it is currently connected to. However, I am now on a new Netgear router, due to the Belkin shooting craps on me, and it happened then, on the Belkin, and it happens now, on the Netgear. So, my presumption is that it has to drop a Wifi connection due to signal degredation, versus simply cutting a decent signal off at the source.
Has anyone else gotten this far with their sleep of death issue? Or is there another thread, that I've missed that I am just repeating? I am curious to see what's out there, before I send this thing off and its gone for three weeks!

I have no issues any longer after finding the offending app on my note and uninstalling it. I don't think there's one cause for this issue. Most often, Android OS updates seem to create program instability in some apps that then trigger the sleep of death. It gets hard to track down issues for individuals experiencing the sleep of death on their devices because we all have different apps installed. You might look at apps on your note that require WIFI to sync and are allowed to sync periodically since one of those may be the culprit. Check comments on Google Play to see if any are known to be buggy under JB. Good luck.
Mke1973, with all due respect, I dont think you are reading my post thoroughly.
As I have already said, this is not an app issue. I have done a reset and the issue still happens when I run it without any apps downloaded and installed. Unless it is an issue with a Samsung app that is preloaded, in which case the fix is still out of my hands, since the owner of the tablet can't uninstall crapware at their will, without rooting it.

Actually, I wasn't ignoring your facts it's just that there are 3rd party apps installed by default that, if you decide to use them, require sync. Specifically I'm thinking of Evernote. Once device makers began pushing out upgrades to JB, some Android users began reporting incidents of the sleep of death when using or after closing Evernote in various Android forums. It wasn't a majority of people, but more than a smattering, but that is standard with the sleep of death. Again good luck on your hunt.
