[Q] screen turning on randomly..help please !! - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

My note's screen turns on randomly in irregular intervals. I am using a rooted LA4 ROM.any suggestions will be highly appreciated!

Install better battery stats and see which app is the culprit!!
SHOT from my LOADED GT-N7000!!

This happened to me on CriskeloRom V6&7 and someone suggested flashing a new kernel.
It is very frustrating& annoying at night.
I am now using Chrack and I do not have this problem anymore.

[Q] Galaxy S GT-i9000M Wake Delay

I've had this problem on pretty much any Froyo build I've installed (tried Doc's, Darkys, etc).
When I press a button (power or home) to wake the phone up, I get a 10 second delay before the lock screen appears. The only time I don't get this delay is when the phone is charging: in that case, it wakes up instantly.
I tried using SetCPU, but it didn't make any difference for me.
I've followed the install steps to a T, and I still get this. This never happened on my Captivate (I have both), and I've flashed numerous ROMs without any problems on the Captivate.
Any thoughts?
As a side note, the ROMs are usually very fast and smooth. I'm currently on Darky's Legendary Steel ROM, v4.0 and aside from the wake up lag, the ROM is very smooth and fast, and this is without having applied any lagfix (used his SpeedMOD version). This is what makes the delay I'm experiencing all the more confusing.
Its a kernel bug, although I thought all the devs had it fixed on froyo.
Try another kernel

Thanks I'll give that a shot. Do you have a particular kernel you know for a fact doesn't have that bug?
Try one from hardcore

Tried two from Hardcore, neither of them have fixed the problem. I'll keep trying others.
Does a stock rom do this?

No, stock ROMs work just fine.

Hi Bro,
2 days ago i try to root my tabs then install battery booster, and now i'm never got this issue again, but i don't know after today, so let's monitoring.
BR
its been 2 days since i also install battery booster, the battery issue is gone. but now i am wondering is this the best solution using an apk for this issue, or maybe i should use my warranty card from samsung to get a new battery instead...

I reset my battery history using the clock work mod recovery, since then I havent had this problem.
Sent from my GT-P1000 using XDA App
this does not happen to my Euro Tab.
okay so i was planning to use my warranty card but the term and condition for warranty state that battery is not on the list

[Q]Android-system 29% of Battery JVQ

Hi,
I recently updated my phone to JVQ but now i'm having a battery drain. The cause (i think) is the high percentage of the android-system. By now its 29% and that's alot. I already deleted the programe software-updater so that can't be the trouble maker anymore. Does someone has a fix for this?
Greetings

Yeah....let your battery go completely dead, then try turning on to make sure its dead
Leave your phone off and then plug in charger until its full, then unplug and plug in again to make sure its full
Repeat these steps 2-3 times and it should be all fixed for you
Also....using titanium backup, freeze the program called "Samsung account" that's another culprit in the "battery drain crisis"

I have already done that a few times, friend of mine has completely the same setup as i have and my battery is down twice as fast. Maybe it's the battery itself?

Is your phone rooted??
Sent from my GT-I9000 using XDA Premium App
Yes, using deodexed stock jvq rom and speedmod k15-t24. Using black background screen dimmed, and everything to make my battery life the best but it doesn't make it one day. So maybe there is a bug?

Try going back to stock froyo, and flashing cfroot kernel so your phone is rooted but not deodexed or any other mods, then repeat the cycle and see if it gets better that way.

Just flash froyo and then repeat the cycle so i don't need to stay a day or so on froyo?

You'll need to be on froyo for about a week or just over, just until you've repeated the cycle 2-3 times bud

Phone does not wake up after ICS

Hey everyone,
I flashed ICS a few days ago and then a day or two later flashed rocket rom. I am not really sure if this problem happened before rocket or not.
My phone randomly "shuts off". Maybe it doesn't wake up, I don't know how to tell the difference. I have to either pull out the battery or do a hard reset sometimes.
Any suggestions as to what I should do? Go back to gingerbread? Or reinstall rocket? flash a different ROM (midnote, etc)?
Thanks everyone!

There is an app called Wake Lock or Keep Awake or something that won't let your phone get into deep sleep so it doesn't happen.
Had the same problem, I remembered from the HTC HD2 forums something about avoiding it by turning off auto-brightness.
After having 4 sleep of deaths in 3 hours, I had it once in 24 hours. Dunno if that's what affected it, but much better. Try it.
Kernel related. Flash a different one. Wipe cache and dalvik after kernel flash.
Some kernels are plagued by this problem because of kernel base used. Minor hardware changes in newer batches do not like the old kernel base.

Help i have irritating problems with my note

This problem started since i was in kdv7.4 and my kernel was glnote core forgot what version it was the last version before hydracore.. using oc version and my voltage group is B
Here is the bug
Some times when i use the phone something appears in my screen its like a black and white wave going down.. after that black and white wave i will soon lose my signal.. at the same time i notice that the gnote is very hot.
I upgraded my kernel to hydracore still the same issue happening( tried to report my prob in the hydracore forum if someone can help me there apparently none)
The above bug was not that irritating yet because the bug will only last for about 5-8seconds..
Now i change my rom to asylum aokp rom v2.0 the problem got worst
The phome usualy goes very hot radomly even without playing games.. then black and white wave going to occur and will shut my mobile signal this will last in a minute.. to solve the prob i need to plug in a charger... tried to ask in asylum forum if they had the same bug they said that their rom is fully stable. And also sometimes when this problem occurs my phone just automatically turn off.. (battery around 50-70 percent) when i try to turn it on again battery now 1 percent dont know why??? Can some one help me with this??? I always do a clean install of roms and kernels.. help please..
Here is the video showing that bug http://www.youtube.com/watch?v=5OMqXzJKeqo&feature=youtu.behttp://http://www.youtube.com/watch?v=5OMqXzJKeqo&feature=youtu.be

Try to format your internal sd.
Try speedmod kernel with kd v7.4
Sent from my GT-N7000 using xda premium
Knock on wood, but I am currently using as well the latest KD v7.4 with the latest version of the speedmod kernel, and I don't have that kind of odd issue you have.
always use speedmod kernel this kernel is way better then hydracore kernel

+1 :good:
Once I had a real nasty battery drain, about 1%/min. Solved it with battery calibration. But never experienced such drain as you describe and don't know how to solve that yet. Does this happen even directly after clean rom installation, or could it be any app or tweaking settings you do afterwards? Do you have the time to check CPU+GPU speed when you notice your note suddenly start becoming hot, and also apps CPU usage, before it crash? Maybe you can get a hint there. Does the same thing happen if you start phone in Safe Mode? It's a good idea to backup rom before you boot into Safe Mode.

Not sure what u mean by 'Better', every kernel has its good and bad side.
Also try moving to Standard version instead of Overclocked. Some Note can not handle OC.
Really needs help. I post a video on youtube above to show the prob... i have erased my whole internal sd change my rom to pa rom. Standard version of hydra core and i still get the bug...

Hi Pierre.. I saw your video and I too am puzzled on what's causing your phone to just suddenly turn off.
just out of curiosity, you did not install some overclocking apps on your phone right? no tegrak mumbo jumbo stuffs to change or speed up your phone before right?
Now if your not using any overclocking apps... you can try using a different brand new battery on your phone and see if the issue still persist after.
Replace your battery.
I believe this is caused by your battery because i get that wave when i use a non original battery ( some cheap ****ty battery ) and that wave starts when im at low battery.
you can borrow from your friends to see whether im right or not

Thanks dude thats what im thinking about also. The funny part is that im using the original battery. But i'll try it. Is battery covered by samsungs warranty?

Don't forget to clean out the battery contacts at the back of your phone as well bud...

I mean, cleaning (not clearing..my apology :silly.. wipe clean the battery contacts at the back of your phone before you put in the replacement one.
go back to stock gb, clean install nothing custom, no root.
Test again, reproducible?
Yes, then Samsung service centre
No, incompatibility with what you had installed Dont go back, unless you install newest versions everything
Send it to samsung service .. they said that my battery port(at the back) was grounded that was the cause of it that also made my battery bloated.. they will change the whole motherboard for warranty.. Back to Scratch..
