[Q] My screen sometimes doesn't turn on? - Epic 4G Q&A, Help & Troubleshooting

Sometimes my screen just doesn't turn on. It still works (I can unlock it and press the reboot button) and all the lights light up but the screen just stays black. When I pull out the keyboard it still stays back. Does anyone have a solution for this?

I have only ever noticed this when my battery gets really really low and then i plug it in to charge. Is this when it happens to you? Also, this may not matter but what ROM are you on?

I'm using midnight rom 4.0 but it has seemed to do it for as long as I've remembered. The battery level doesn't matter it just does it whenever.

Are you using setCPU or Overclock Widget to change the over/under clock?

I am using setcpu.

Do you have the screen off speed set at 100mhz? That can cause problems.

Nope I don't even have profiles set.

What is your minimum speed set at then?
Sane problem if your minimum speed is at 100mhz.

I'm not completely sure if it was or wasn't. I'll make sure that everythings 200+. Thanks for your help.

No problem, keep a lookout with kernels, a fix to allow better scaling so you can set your minimum at 100mhz should be coming soon.

[Q] CM6.1 wake issue

So i just swiched from virtouos ROM (sense) to CM6.1 and i am having a problem.
when i first flashed virtouos, sometimes my phone screen wouldnt turn on with
first attempt but after setting profiles on setCPU it was fixed and didnt happen anymore now with CM6.1 i am having a slightly different problem the screen doesnt turn on when i am receiving a call (it rings though) and i have to press the power button couple of times to get the screen on. i have already set some profiles on setCPU ,i am just wondering if there is any fix for it ?
Thanks
Only thing anyone can probably suggest is turning up your min clock speed. What are your profiles set to?
My screen off is 245/368 just to give it that bit extra to guarantee no wakeup issues, not that I had any to begin with, better safe than wanting to throw her up the wall (I get annoyed easy).

Doesn't sound normal... did you make ANY customizations at all? Or did you install CM straight up and just use it like that? Any adjustment to "performance settings" or CPU clocking? What SPL and radio do you have installed?

no i didnt make any customization its just CM6.1 although my max clock speed is at 1497 mhz
setCPU
Screen off max 368
min 245
and profiles for temp and battery as well
the wierd thing is it doesnt happen at all when im just waking the phone up it only happens when its ringing i am thinking its my CPU issue ,i dont think it handles overclocking well ,i couldnt go over 1.1ghz (it would freeze instantly) with virouos that was the main reason i switched im gonna play with with cpu profiles for a while and see if i can get it fixed.
btw i have never flashed any radio so im guessing its the stock one
wow this is very intreasting its actually fine without any setCPU profiles
i had something totally different in my mind.

With my experience I've noticed the phone runs better, and lasts longer on a single charge WITHOUT setCPU profiles. Just my opinion

Battery usage monitor?

Hi Guys!
I am facing a very extreme battery draining situation...
Something is keep waking up my phone while my screen is turned off.
Is there any good app out there I could monitor / Find out what is constantly waking up my phone? I can not find any good app for that.
Thanks for your help in advance.

Settings->About Phone->Battery->Battery Use
Get yourself rooted and grab SetCPU. I have a profile set on that which underclocks my CPU when the screen is off. Doing this GREATLY increased my battery life.
I also use Tom Hubalek's Battery Gauge Widget to help me monitor my battery. But, after using the RCMix S v2.0 ROM and calibrating my battery (and the mentioned CetCPU settings) I get a good day out of my phone with a lot of wifi and 3g usage.
Never had any issue so far with my battery... I am checking battery usage in the settings menu but it is not enough. Need to see what exactly using my battery 'cause its unacceptable to drain 60% in 5 hours... The only thing I can see that something is using (waking up) the phone even when the screen is turned off...
I am using SetCPU as well with Smartass governor... can not be the problem...
Also set a profile for screen off - i have it set to 245min-245max smartass. It seems to save battery more than just set on the main screen.

Have you tried changing the Wi-Fi sleep policy? Also, pocket mode and fastboot, if you have those options.
My SetCPU is set to OnDemand. I thought Smartass was unstable and gobbled more power than it should? I dunno, though, I use whatever the ROM developer uses for the ROM; I don't change anything.
But you're right, my phone has lost 61% in 14 hours. 60 in 5 is wrong.
I think JuiceDefender has some of the features you're looking for, though:

Ach, I have mine to 245-600MHz when the screen is off. Any less and my rom is lacky when the screen wakes. Had the same settings as you for other none Sense 3.0 ROM's though. MAJOR power saving. If you leave your phone downloading, though, the screen off profile kills the download rate.
Check it out, upload a file to your phone via wifi, turn the screen off and watch the speed plummet to about 100kbs!

Anyway, I had a massive power saving when I used this ROM:

Dialer
If you're using a gingerbread based ROM, it could also be the dialer. At least it is for me. Sometimes he just goes crazy and I have to reboot the phone. Apparently the dialer checks the phones proximity using the sensors again and again.
For further reference and solutions see: http://forum.xda-developers.com/showthread.php?t=1069251
Juice defender and Setcpu are in the same basket as task killers.
If you are using Smartass you don't need any profiles. Check your widgets, probably you have one which updates every second and kills your battery.

Wake problems.

My phone sometimes doesn't wake when I try and turn it back on after a while when the screen goes off.
I am running CM7 7.1.
I am using default oc settings. (ONDEMAND, 300-ish min, 1110-ish max, no undervolting as far as I know)
I tried to press the button combo to get fastboot but it doesn't work either. I have to take the batteries out for the phone to restart and then it works again.
What gives?

368 is the lowest you should go and, even then, you might run into wake issues. Additionally, if you have anything like SetCPU installed, be sure you don't have a screen off profile set with too low a speed.
Sent from my HTC Vision using XDA App
It seems to be mostly a cpu clocking issue. Raise your minimal clock for screen off profile if you have one and it should work.

I don't think that is the reason.
Back during CM6 6.0 RC1, I had set CPU with 256mhz off screen, and it was perfectly fine back then...

Are you using SetCPU?
If you are (and it's really not needed anymore) make sure your max on the screen off isn't set low as well. You can sometimes get away with a low min but, if you have a 256min/256max, you're basically telling your device to stay at 256 whenever the screen is off and no amount of pushing the power button to wake it will change that.

Not. I uninstalled SetCPU. Using the built in govenor now...
The problem you seem to be having is a bsod or black screen of death.
If you search that term in the forum you will find a few posts about it.
The only thing that i am aware of about the issue is that it is related to the use of your gps.
I have had trouble replicating the issue, it happens very randomly. I sent my phone to bell and they didn't fix it...

In my case it was a battery issue.
To be sure I tried the experience 3 times: OEM battery for a day, ebay one for an other.
At the end I had a black screen ( sleep of death) every time I turn off the screen on the ebay battery (galilio).
The voltage was alright, it was something else.
running virtuous unity 2.37
I've had problems with the screen-on and screen-off animations causing a black-screen-of-death.

My Nexus not waking up?

basically just recently i have noticed my Nexus not waking up.
will simply go sleep perfectly fine but sometimes will not wake and sort of reboots in away.
tried all sort of ROMS, kernels, radios with no effect. even switched back to ICS but still get the same results.

Did you try wiping everything on the phone and starting fresh. Go in the Android Revolution thread and run the superwipe script and wipe again then reinstall everything see if that helps.
I didn't look at the logcats, too tedious.

Does this happen on stock. This logcat is using franco's kernel, are you UV'ing? OC'ing? Smartreflex? I don't know if actually Francisco is using official stock voltages today, or is already uv'ing a little from source.
And I just finished going through your log, there's nothing useful there; you should be getting it while it happens, or better yet would be /proc/last_kmsg immediately after the reboot; Grab it like this, for example:
Code:
adb shell cat /proc/last_kmsg > last_kmsg_on_my_pc
Also, what you're experiencing is called Sleep of Death.

Are you using any app to control your min CPU voltage? the problem might be that your phone doesn't have enough power to come back from sleep or just takes really long if the CPU voltage is too low...

Why? It's more likely that it's the voltages that are causing it, they're probably too low for his chip. What you're saying is that "it doesnt have enough power", so you're kind of contradicting yourself. And CPU ramps you know? So, if it meets a intensive task (if you call waking up the screen and bringing up UI an intensive task), it will ramp UP to the next step, until it reaches the defined workload percentage for max cpu speed defined in the governor.

It seems you didn't understand where you're contradicting yourself.
min cpu frequency is not equal to min cpu frequency voltage. If you set min cpu freq to 700mhz step, but lower the voltage to a value where that same cpu step it's not stable, it will still have issues.
Another thing I recalled: OP, are you limiting your MAX cpu freq, WHEN screen is off? Like with cpu profilers and such apps?

[Q] Trinity Kernel settings

I reflashed stock JB kernel the other day and found my phone to be running very smoothly. But I can't stand the colours on my purply screen, so back to Trinity (latest stable release).
The problem is, I'm getting a lot of lag and jerkiness on Trinity. Google Now takes forever to load, responsiveness takes a hit, and it generally feels like that whole "Project Butter" has turned into cold chunks of margarine.
I did buy the Trinity app to change settings. Is there anything I should be doing with Trinity that would give me stock-like smoothness and performance? I have a feeling there is some default setting in Trinity that is supposed to be helpful for some users but for me it's just killing the experience.
Or alternately, would I get better results with Franco?
I had similar issues. Not flowing very well , reboots and crashes. Also even though I bought the trinity app changing the clock speeds made the phone very very unresponsive. Tried many times to install it but no luck. Swapped back to Franco / glados (tried air kernel which was nice for battery but a bit laggy)
Franco also has trinity settings you can play with

Me personally had a better experience than Franco. But all the phone are different and some might like trinity and some might like Franco. Seems like yours like Franco more
Swyped on my Galaxy Nexus running AOKP with Trinity Kernel, overclocked to 1.4GHz
Personally I've had ridiculously good results with Trinity - with 384 GPU, not 512 (1536-384-Stable35). Absolute butter even when I have very resource heavy, multiple, tasks running - and havn't had a forced reboot, freeze or anything of the sort even once. Interactive/SIO, min 307, max 1190. Everything else on default (except screen colours/gamma which I changed to my liking).
That said, if the 384 GPU is also not working for you I suppose you can give Franco or the other kernels a try, every phone set probably responds a little differently to each kernel.

try using supersu instead of superuser. also, update your busybox. a lot of people have issues with root apps obtaining su slowly with superuser on jelly bean, which leads to lag.
I have good flow with trinity kernels. No lag or unresponsivness

Already doing both, thanks for the input.
I'm using 1344/307 and I also previously tried 1536/384. My phone seems to have some overheating issues so I don't want to crank it too hard... Just want to get close to stock performance.
I'll try interactive / sio. Are those essentially what the stock kernel uses?

i like ondemand/deadline. overheating.. whats your cpu temperature? most think that their devices are overheating when it falls in the normal range. tkt comes with widgets(in the app drawer widget menu), put the no background cpu temp widget on your homescreen and youll also get a cpu temperature reading in your status bar. at 100C the thermal throttle will kick in to lower your cpu speed and cool down your device. the safety shutdown temperature is 110C, your cpu will automatically shut down at that point. 110C is only reachable if you turn off the thermal throttle in the tkt app and you are benching your phone at a high oc. otherwise, i wouldnt worry about overheating.
The other thing is I get lockups every day or three. Today I rebooted the phone and plugged in the charger while it was rebooting. The moment the screen went off the phone was locked up. Power button would not respond. Unplugging/plugging the charger did not light up the screen. Had to do a battery pull.
In fact this happened again a second time in a row. Is there a reason the phone is locking up immediately after boot if I have the charger in? I'm trying it again a third time with the charger out, letting the screen auto-sleep before I touch the phone. Okay apparently it has nothing to do with the charger.
EVERY time I start the phone up now, if I don't unlock the screen myself before it auto-sleeps, the phone locks up and auto-reboots again. WTF??

are you undervolting at all? which yrinity kernel are you using? did you happen to use franco kernel before using trinity? try using a different charger too, ive had similar issues with a certain charger before too, until i started using a different charger.
Despite the fact that I disabled "Set On Boot" in Trinity Kernel Toolbox, it does seem I'm still set to interactive/sio on boot. And check out the logcat I captured over USB when I was doing a reboot and it locked up:
http://pastebin.com/sSe9eFXT
In particular to trim out just the TKT lines and the last few lines before lockup:
Code:

So it would seem that right after TKT says "let's restore settings" it locks up, if the screen is off, when set to interactive/sio. Huh?

See my post immediately after yours.
No undervolting at least that I know of. I tried cranking max screen off frequency up in case that was the cause, and tried going back to default CPU settings. Still does the same upon reboot.
But I can confirm that if I uninstall TKT completely and boot with Trinity Kernel, there is no screen-off lockup. Whatever settings were being restored by TKT were causing the phone to freeze if the screen was off. I'll leave it at that for now and give it another go when it's not so lovely and sunny outside.

delete the data for the tkt app(main phone settings, apps). dont use set on boot, its usually not a good idea. my screen off is set to 307. if you are overclocking, you have to disable smart reflex mpu or you will freeze and reboot if not other issues. turning off smart reflex is very important if raising the cpu speed. otherwise the device will try to automatically set the voltage too low for the cpu speed and itll cause freezes/reboots.

I didn't overclock and I didn't undervolt. What is smart reflex?
Set on boot was DISABLED, let me emphasize. Yet the logcat shows TKT restoring settings, followed up very soon with a lockup.

does your rom have its own cpu settings? maybe theres something enabled in there?

smart reflex is a built into stock, it controls your voltages. the thing about it is that it doesnt know overclock or undervolting, so if you overclock or undervolt, it restores voltages for stock cpu speeds. which causes freezes if youre trying to overclock by setting the voltages too low.

Stock yakju Jellybean flashed straight from Google image files, with the exception of Trinity.

did you try clearing the tkt data, or uninstalling it and reinstalling it? honestly, this is the first time ive seen this behavior. do you have any other cpu control apps installed?

Yes, set on boot is for critical settings only, like frequency policy and voltages.
All trivial settings are always restored as they were set.
What ROM are you on? I jumped into the middle of this page and missed it.
Side note, if it's settings being restored, clear the app data using the option in the menu.

No I do not. I will try reinstalling now since I uninstalled it completely.

Again, pure stock flashed straight from Google, except for Trinity.
