Black screen aka black death

Seems like a lot of people are facing problem waking up the phone resulting in getting black screen and nothing else.
I faced the same problem too that is why I decided to create a new thread specifically on this.
Let's share what caused our phone to go into coma based on our observations so that in time, the root of the problem can be traced.
Based on my observation, when my phone is left idle for some time, say 1-2hrs, it tends to become sluggish and setcpu will stuck at max or min value (Yes! sluggish even when stuck at max value!). Given long enough idle time, it will fail to wake up (e.g. every morning when i wake up after 7-8hrs of idle time).
I was using OpenDesire v4.0.10 and just changed to v4.0.15 to see if it still exist. I have setcpu set on 1075max 245min (ondemand) and 245max 245min (ondemand) when screen off. Also, using task manager.
Please share your observations and phone settings (ROM, versions, setcpu, task manager and others)

have you tried removing setcpu?

Nope, but in OpenDesire thread, people without setcpu experienced the same thing. Do you have such problem?

I noticed using setcpu does make the phone sluggish. when uninstalled problem was solved.

Perhaps, a more tailored topic title will help all readers understand what you're talking about.
However, HAVS kernels is the only common factor and SetCPU is not the cause.
And, my two cents, I don't think this issue deserves a dedicated thread since is specific to a single kernel flavor.

I created a specific thread on this topic because there are many people out there experiencing this bug and there is no dedicate thread to discuss it. I assume you are not facing this problem because otherwise you would understand the pain and frustration of encountering this problem repeatedly

Undervolt is a kernel mod that you install and it lowers the cpu drain by setting it to use lower volt values on each cpu freq. This cause it to stay cooler too.
Look for it in this forum. [Kernel] undervolt

I am suffering from this once per day on Defrost and OD so I suspect its kernal related. I am running the default HAVS kernel at the stock 998 frequency. I uninstalled SetCPU yesterday and had a lock this morning ( Defrost 4.1 ). The notification LED was flashing orange. So SetCPU is not causeing the problem. I have swapped over to SVS so I will report back on how that goes.

I use OpenDesire 4.0.10, then 4.0.15, then 4.0.16, each release for at least 3 days, and not for once have I encountered such "black death"....no setCPU of course.
Care to elaborate what apps you have there ?

That issue is relative to OpenDesire and DeFroST ROMs only, and when they use a particular kernel version (HAVS) on selected CPUs, so I continue to think that it'll be eventually sorted out by the respective developers and/or Kali- and the kernel team; those guys do monitor the ROMs threads so they're already aware of the issue.
And yes, I suffered the issue twice, as I wrote more times in the DeFroST thread. "Pain" (panic?) and "frustration" sound a bit strange to me, when dealing with overclocked, custom, highly tweaked cooked ROMs. If a reboot scares you, head for a stock HTC ROM and you'll be fine.

I was worried I was the only one who had this. Thread title isn't that helpful for people seeking advice on it though. Get this after every reboot for about a minute until everything is back to normal.
Had the sluggish issue when using YouTube after about 20/30 mins, other than that I've had no lags.

Double post

I got this on a svs kernal, so its not just restricted to havs. I had 1300 svs installed. With setcpu. Done the same with 1267 svs.

I've also had this issue on SVS kernels, was also having a series of hard resets last night - have rolled back to an earlier version of my favourite ROM flavour for now.

Never experienced anything like that...Although there are times that my Desire's performance would remind me of the bad old Diamond days,where patience was a virtue(well,not a virtue,but a money saving method!throwing your phone to the wall with your full strength after it frustrates you with being slow is known to be a costly process! ).Seems to be some apps running in the background...Maybe if your phone recovers after it without a reboot you can check if any apps use a larger than normal amount of ram.Other than that...Well,god is almighty and people experiencing epiphanies are known to work wonders through the ages!
And something completely off-topic(sorry about that).When using an undervolted rom/kernel you are not able to overclock to values as high as when using a normal-volted(is the word right?I dunno...) rom/kernel,right?I mean,what would happen if someone tried to overclock to 1382MHz(I know,I like the limits) using an undervolted kernel?And finally,how does this all apply to the hardware?Does UV affect the CPU's health like overclocking or something like that?
Thanks a lot!

I've had it on OpenDesire 4.0.10 and 4.0.15 a few times. Stopped happening when I stopped using profiles and defaulted back to to 998/ondemand.
Will try running it on 998/interactive for a while and see what happens.

No lockups after SetCPU to ondemand. OD 4.0.15.

Separate thread IS useful, otherwise replies get lost in ROM threads where the focus is not specifically on this problem.
I too had this issue three times. DeFroST on all occasions, versions 3.x iirc. Never tried the HAVS kernels, just plain default what is shipped with the ROM (SVS @ 12xx Mhz?). Also SetCPU'd it, have not yet bothered to try and turn that off yet. SetCPU keeps it at 995 Mhz max, interactive governor, while switching to powersave while asleep.
Issue happened twice while browsing (possibly with Flash ads on the page by accident) and the power state switching (i.e. turn the device off quickly while running for train, afterwards reading for 2 minutes again, etc). Third time it happened while tethering my internet connection to my laptop.
Hth

I had this problem few times a day when I upgraded OD to .10 and the new ADW on the same day.
Then I restore back the old OD with old ADW, then no problem.

Peoples rom v 2.2

I am running a clean install of peoples rom v 2.2 on mtd. At around 15% battery life, the phone shuts down as if its completely dead. I restart the phone and it shows around 15% battery. Any ideas on what's causing this? I have had this happen on a few roms now, also happened after about 2 months of running the clean gb rom. Another issue I am having is on certain apps, like facebook or gmail, when I open the app, my screen flickers as if I am having a loose connection inside my phone. Doesn't happen on every rom, but its happening on this rom. And last question, my wifes epic 4g keys do not light up anymore on her physical keyboard. Tried different roms and even stock. Still no lights. Any help? Sorry for the lot of questions. Thanks for the help in advance!

#1: Search for threads on battery calibration, or look in the People's thread for Kenny's method. Some say it works, others say no, but YMMV.
#2: Settings in Voodoo color too low. Use Voodoo control to adjust until no more flicker.
#3: Hardware issue. Take it to Sprint.
EDIT: Here's the settings I use on TPR. No flicker and looks awesome.

I have tested these settings on a personal kernel with mdnie disabled.
These should look fine on cm9 on most if not all kernels.

[Q] Does anyone else's A100 slow down

Does any one else's a100 become super laggy after a few minutes of being on.. I am running the latest flex reaper I even overclock it all the way but I get this huge lag after the first few minutes of being on.. anyone else experience this or have a fix for this?

I do not experience this issue. When you flashed the rom, did you do a clean install? Have you formatting the device?

Yup.. I format everything.. I use the touch recovery and just use every option that it provides and wipe everything.. It even does it when there is nothing installed. I usually delete almost all the useless system apps that I don't use like the google music app and all of the ones civato provides... I even change the animation settings to .5 in the developer section.. should I turn them off all together?

The animations should not have anything to do with it. Does this only occur on that rom? Have you tried other roms and experienced that issue?

not many other roms out there.. I have used stock and his.. had the same issue on both.. Also happens on my brother's a500.. it usually happens when unlocking and going into any app.. it sits there for a few seconds and then opens whatever it is i opened

This is starting to sound like a hardware issue. Before that is concluded, you could:
- Make sure the governor is not set to "conservative"
- Try a clean install of CM9
If the problem still arises, its most likely a hardware issue.

I'm using the OC kernel and have it to 1500.. I also always leave it on performance.. I figure it would kill my battery life but I don't use it much.. and i tried cm9 also.. too many issues as of right now

It doesn't seem it can be anything else but a hardware issue in that case.
NB. Overclocking to a high frequency can cause instability and bring about that issue (but since you experienced it on the stock rom, its quite likely not to be that).

the overclocking helps to speed it up a tad bit.. for the most part it just lags.. i did a clean install just now

Thought I would jump in. Stock ics would slow down and lag on me, jittery transitions poor performance in games or movies, but it took an hour not a few minutes. However testing the T20 kernel before the release kernel had that exact issue, bogging and lagging within minutes.
His release kernel doesnt do it, and flex extreme as well as my cm9 builds don't, even with T20 kernel. Consider flashing that kernel to see what happens.
Side note...what issues did you have with cm9? And what release? My build 1 has been running for 3 days no reboots stable as can be undervolted and OC when needed. Something to maybe think to try to see if it persists. T20 kernel works fine with it too.

That reminds me...setting a screen off profile with the same min/Max speed can cause issues with that, give Max a notch or two higher. And don't have it change the governor leave it the same. So like interactive screen on Myst nit be conservative screen off, doesn't work that way.

I had the same issue on stock. I noticed there are 2 weather applications installed (version 1 and version 2) immediately after I disabled the old weather application (version 1) this stopped happening. I used the ICS GUI to do the disable.
This might not be the case in custom rom, but is true for stock. Post reply and let me know if this fixed it for you also.

Do you have a micro SD card plugged in? Try reformatting the card with a computer. Worked for me.

I felt the need to add my two cents in this....this has been happening to me for the longest with the flex reaper rom ONLY. I've used stock and ZN's rom and those did not lag after unlock...only flex reaper. I'm currently using flex reaper and still experience it from time to time but doesn't destroy my day at all...

Give the CM9 nightly ROM's a go. No Bluetooth n no HDMI audio, but everything else is fine n damn smooth. Those issues will be fixed though

I installed Flex 100 Reaper with stock and it it seemed to run smooth enough. Then I installed the OC kernal, and started to get lag. I was looking around to find the OC settings, but can't see it anywhere in settings..
Can anyone direct me to where can I adjust the governor/max/min CPU settings?
Sorry for the noob question.

The definitive unresponsive touchscreen topic [Black screen of death]

As apparently many of you have witnessed before, there are situations where the Galaxy Nexus becomes unresponsive to touch input.
For me, this most of the time is noticeable when trying to unlock the phone. The phone just doesn't respond to me trying to unlock the Screen Lock (Setting: Slide).
The only way to get out of the situation is pulling the battery and reboot. One thing I notice after this routine, is that the phone has lost a lot of battery juice.
I've read a lot about this problem on multiple forums (XDA of course, but also Google support etc) and none of them have been able to pinpoint the exact cause.
There are, however, a couple of applications and settings that are more likely to cause the problem, but feel free to mention your own "suspicious" apps.
* [App] Light Flow
* [App] PGM Nexus
* [Setting] Auto Brightness
Please let me know if you've ever encountered above problem, on what version of Android you are, and if you're using on or more of the above apps/settings.

Had it on CM10 stable, disabling pgm did the trick. (I use auto-brightness but no lightflow)

I had this on rascarlo 4.2.1 /w Trinity & Franco kernels.
All I had from your list was;
* [Setting] Auto Brightness
I was also reading the developer options animation set to below .5x could increase the SOD.

[Q] Core and frequency control according to temperature

My N2 makes me crazy when it gets warm.
When it reaches about 36 celsius degrees it starts with frequency limit of 800MHz.
The second step is making 2 cores offline and at last my gadget becomes limited to 2 cores at a max. of 500MHz.
It becomes almost unusable for me when in car. I use two navis in multiwindow (Waze and Sygic) and AutoGuard recording in background with FullHD and in about 5 minutes it's restricted hardly.
I know it's for safety reasons but I think it's too strict.
Is there a possibility to raise the thresholds of these by a few degrees?
What kernels support this?
There is a nice app called Android Tuner which is able to set these tresholds but it is for Qualcomm CPU-s only...
Thanks for any answers in advance!

Not exactly understand...
There must be a safe setting for it as with Perseus kernel the thresholds are higher, but not too much. I forgot to edit my question according my experiences with Perseus.
At least with Perseus I get a max of 1000MHz at most cases but it is not enough for me cause I use apps needing high resources.
Would You be so kind to write about the value to be changed in order to get higher thresholds?

If I understand you correctly. Then you could try trickster mod.
Or try saber kernel. I use this baked into the Jedi rom.

Thank You for the advice!
Now I had some time so I'm on Saber kernel and just testing.
The testing is awesome till now: the phone is working more powerful with this kernel and doesn't get hot so soon. :good:
Oh, now there is something strange, the programs get FC-s...
The phone is on charger, I ran AutoGuard in the background in FullHD, Sygic and Waze in MultiWindow, VideoPlayer in popup with a FullHD video and SuperPlayer in popup with another FullHD video. It was extremely fine but after a few minutes the players collapsed and AutoGuard had an error. The system is stable anyway. It seems I have to restart phone now...
Edit: After restart I got an old problem back: Dropbox is unable to run again... I loved Perseus because of this, on Perseus this problem was away... I hope that I won't get the other issue back with my WiFi... And it seems, AutoGuard became stupid too... :crying:
I don't give up and keep on trying to make them ok.
But I can't find the thermal control feature in Trickster Mod Donation altough I have just a minute for it.
I am reading Trickster webpage to get ahead...
Question: Are You using Jedi ROM and have no thermal problems?
In that case I'm going to try that ROM, cause I'm on hunting for a ROM that works with no problems for me.
I tried some lately and till now Omega v18 was the best amongst them. I tried MIUI, ProBam, Hawkish in the last days and I get problems with all of them or had non-working applications and/or features which ones are essentials for me...
Edit: mmmmmmmm, as see there is no Jedi ROM for international N7100...

hey bro,
wow you seem to be a bit more advanced than me so maybe ive reached the limit of the advice i can give you.
However, if you inform me how to check for thermal problems i will surely do that and then report back.
the saber kernel to the best of my knowledge is underclocked so if you try to o/c it maybe that will prevent your fc's. I have read in the various threads, of which the community is very helpful, of some issues for heavy users due to the u/c.
Regarding the jedi rom i am a uk 7105 user and to the best of my knowledge i thought it would also work for international 7100 users?!?!
Here is the thread i use.

Thank You for Your effort!
I'll keep on investigating for a solution.
Unfortunately the real test was horrible with Saber kernel, when I tested it in car the temperature got high soon and the thersholds were low again.
But it's a good idea to try o/c thank You very much!
I'll try it tomorrow, now I have to go to play Cod4... :laugh:
And I found that TWRP is recommended for Saber and a few minutes untouching after the restart so I'll try again.
Have a nice day!

Thank You again!
I got some experiences with the newest Saber kernel and I like it 'cause the first kernel I can use 100MHz step with and using 300MHz step too.
It seemes to be good at battery consumption too. My only problem that this kernel doesn't support STweaks so I can't regulate charging voltages like I used to. Perhaps only Perseus kernel makes it possible as I can't get any other programs for it till now. Or NEAK kernel and the new versions of AGNi pureSTOCK kernel as I read their pages. I'll try them some day. But Perseus is my favourite.
I think it's important to say that the kernel isn't UC/OC by default so this doesn't make any problems and it's not UV-ed too.
I set min. to 100MHz and max. to 1920MHz to test and it's stable till now. I tried to Overvolt slightly and had no change on media programs behavior they don't like each other as I see.
Trickster Mod is nice 'cause it shows the CPU temperature which was helpful to understand this regulations of thermal control are needed.
When I tested it turned out that CPU is below 70 degrees while the battery temparuture is 'only' about 40 degrees.
So thanks for Your kind advises!

wow. Ok i think i understood most of your post. probably a little bit over my head but i need to learn.
I really like the new kernel im getting 1% battery drain an hour with the screen off which truly is unheard of for me,
The kernel runs real smooth apart from when i play asphalt 8. Or i should say it runs smooth playing the game until the phone tries to do something else. For example if it attempts to update a programme or if a message/email comes through. then the game just lags and i have to wait for the phone to stop multi tasking before the car starts to move normally again.
So im surprised to read you say the kernel isn't uc/uv by default??? I was pretty positive it was. But i dont know for sure and im probably not clever enough to figure it out lol.
I wonder what settings i would need to increase to aid the phone in its multi tasking? Also there must be some kind of programme we could use that would test our specific phone/cpu and tell us which settings it would prefer. As i believe each phone will run slightly different?
You are right i remember reading the kernel does not work with stweaks.
I wish i could work with you and figure out how to optimise our settings but i simply dont have the skill set.
I presume you used trickster to overvolt slightly?

No, I didn't overvolt at last. But once I tried and didn't helped on my problems.
Unfortunately now I'm back on Perseus kernel again 'cause some issues with Saber. It became crazy every time and locked my CPU on 160MHz only and only reboot helped.
The other issue was the stuck system server process what was active all night and didn't stop hard work.
Now I'm on reading the kernel's page till I get cleverer on it... then I perhaps try it again 'cause I liked it.
