[Q] Screen flickers when it wake up from sleep

This is stock ROM.
Every time I flash bacon bits to overclock my phone I always noticed that my screen flickers when I turn off the phone's screen or press the button to wake up.
Sometimes it just gets stuck and it stats flickering like crazy and I can't unlock my phone because of it.
This only happens when I OC my phone. When I wipe the phone it works fine but no OC which is what I want.
Any way to fix this issue?

I don't use Bacon Bits, but I have experienced the flickering you speak of. It seems that happen when you go too far with the OC process. What happens if you were to lower your clockspeed a bit? Does it continue to happen for you?

Actually I OC my phone, but it's still set on 806MHz so even at lower clockspeed it still flickers. It's bugging the hell out of me.

EDIT:
Switched over to pershoot's kernel: http://forum.xda-developers.com/showthread.php?t=847672 I can now overclock to 1.5 gHz with no problems anywhere. Aweseome.
I have this same problem and am bumping this thread.
I'm running stock rom with bacon bits v 0.3 - and my screen flickers when turning off so much that it won't turn off fully and opens the lock screen. I have to just try and try repeatedly to get it to work.
Any suggestions?

Yeah, I have flashed all the kernels even pershoot's and it still flickers. I'm using the original ROM that came with the phone not the original one posted on the forums. Maybe if I use the one posted on the forums that will work?

I have the stock rom as well - I first flashed baconbits kernel, but when that flickered, I flashed pershoots most recent kernel in recovery. No flickering anymore - sorry to say I don't know what's wrong. Try posting in the thread of the kernel you are currently running!

Well you know what I flashed an older version of pershoot mayeb I should try the newer one. I'll let you know what happens...

I had trouble flashing it with ROM Manager. Clockworkmod it. Here's the link to pershoots blog with the latest update links: http://droidbasement.com/db-blog/
Good luck!

Pershoot is always monitoring it along with a bunch of other smart devs. Maybe they'll have a better idea - don't give up hope!

what app are you guys using to manage your OC?
if it's setCPU, set your scaling to Interactive on the main screen and in any profiles you're using.
also, if you are using any screen on/off animations, disable them (just to see, for troubleshooting purposes, if that might be the culprit)

Yeah, it's set on Interactive and so are the profiles. As for the screen on and off animation I believe that's in the CM7 RC1 ROM. I'm using the stock ROM so there's no option for that.

hehe, didn't even read what rom you were using. my bad.
kernels aside, it is very possible, as you mentioned earlier, that you guys got the chips in the stash that don't take to overclocking very well. even on a device like the G2/DZ that seems to take to higher clock speeds relatively easily, there are bound to be some that aren't as happy with the increased workload.
if I think of any other bright ideas, I'll let you know. I haven't played with baconbits a lot.

[Q] Stock Phone doesn't use 192 Mhz clock speed

So I know a lot of us don't use stock here, but my gf likes her phone stock so I had recently debloated her phone. I started to notice that her phone didn't spend anytime in the 192 Mhz clock speed. I tried using setCPU to change the min/max but to no avail. So my question is, is this stock kernel behavior or did I screw up somewhere?

[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.

To prevent the lagg after unlock, I set the governor to ondemand and the minimum frequency to 312.

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.

franco kernel sluggish or phone damaged?

Hi all,
Today I installed CWM and flashed franco's kernel for JB (the newest one). At first it seemed pretty fast so I was happy. I decided to install setcpu and set it to max 1,8 ghz with set on boot enabled (I know it was stupid, but I did not realize it at the time). After rebooting the phone froze and a purple layer appeared on top of my screen. Seconds later my phone rebooted. I set setcpu on 1,2 ghz max and let it stresstest for a couple of minutes. No errors were found. But now my phone lags sometimes, like if project butter just had disappeared and the normal android sluggishness has reappeared. Is this a kernelissue or did I damage my cpu with this stupid overclock? Btw, apart from the sluggishness in the animations I can run everything just fine.

I'm on Franco and have no problems. Why don't you try another kernel and let us know how it goes?

I understand people want to ask questions first, did you try to wipe and reflash?
At most I can probably assure you, you didn't damage your CPU.. there would probably be more dire issues if it was.
Did you flash a new kernel yet?

Not yet. Should I reflash franco or try another? Can I flash a new kernel over another kernel without wiping my whole device?

Yes, I've flashed 3-4 kernels on one ROM. You can dirty flash your ROM too or completely wipe and flash.
Either way its fine. I do suggest wiping and flashing though..

And should I uninstall SetCPU in order to get stock CPU speeds? And what issues would I have if I would have fried my SoC?

Setcpu is fine. In order to get stock, either use a new kernel or dirty flash.
Assuming.. if it was I'd guess the phone probably wouldn't be running?

You need to learn about what you're doing before you do it!

I flashed the trinity 1420-537 JB stable kernel, and everything works as smooth as it has to be. The strange thing is that it was a bit sluggish until I changed my wallpaper from a live to a normal one. Now I switched back and everything is still smooth :? . Anyway, does this kernel overclock the cpu itself or are the speeds in the name just the available range?

if I have such issues I will never flash an oc kernel to look if everthing is working. Install stock rom kernel back and try. If everything is fine......you can try an oc one.
On Trinity; first number is MAX CPU clock range you can chose and second number is fix GPU clock.....or just reading FAQ, Changelog etc. will answer your questions really quick

from what I've heard, some gnexs are really picky with roms and kernels. I guess your phone is one of them. I personally had problems with Trinity Kernel, since when I reboot, it sometimes bootloops for 5minutes and such. I personally had no problems with Franco though. In fact, I use Franco as my daily driver

Franco's app let's you easily tweak the settings (overclock, change governors, etc.) which may help the sluggishness. I almost exclusively run Franco and his M5 is amazing!

A reflash might be the best option ... either the ROM or Kernel or Both lol thats my inner crack flasher talkin'

Never had problems with franco. It's trinity's kernel that made problems for me.

I run Franco's kernel myself. Just have to be careful with flashing the nightlies, it can be hit or miss. They are experimental.

i actually find the power saving feature more power consuming(aside from brightness and vibration), i think it causes all processors to start up at lower frequency rather than 1 cpu at high frequency.
