Display malfunction - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Hi guys,
Maybe some of you have experienced this before, when I put my note away the screen of it gets lit up as if there was an app keeping it from sleep mode. But this happens even right after I have terminated all apps and processes. So technically barely anything runs. I think it might be a software issue? Any ideas please?

Install the CPU spy.apk (Play Market). This app will tell you if your phone is in deep sleep.

can u post the battery stats

open your battery, wait 10 seconds, reassemble and turn it back on... if you're still facing the problem, install and run CPU Spy from Play Store and see which app/service is keeping you phone from sleeping and uninstall that.
It's probably a kernel wakelock

Will try the CPU spy application now. Will post my findings.

How exactly is this app going to tell me which app is keeping my phone awake? Don't see such a list of them just frequencies.

Should I be looking at these processes that are possibly waking my phone up? So far I don't see how this app is solving my problem.
Thanks so much

this l2_hsic wkelock is mainly caused by unplugging the charger without unlocking the lock screen. or unplugging when the screen is black.
Its a known bug
shutdown ur phone., pull out battery, wait for 10 secs., reinsert and reboot. The wkelock should be gone. test again with betterbatterystats
# message swifted from Note, travelled in the air to gateway and wi-maxed to [email protected] #

Thanks. Will try that!

There are several processes that are there, unfortunately not only one that I could just spot.

Screen shifting issue

Sometimes while using my tablet, the screen suddenly "shifts" out of place: http://imgur.com/a/94hr8 Sometimes it also gets "corrupted": http://imgur.com/yErJp.jpg The tablet works normally when this happens, and it responds to touch at the correct position(i.e. touch doesn't change). It doesn't show up on screenshots. I haven't noticed it being "linked" to anything specific, and it's always done it. Turning the screen off and on again returns it to normal. Why does this happen? Is it solveable? I've tried googling around but nothing.
Thank you.

maybe you can post more details on your device
which rom? which cwm.....
It is completely stock 3.2, only rooted with a zip I flashed from stock recovery. I'm pretty sure it did that before rooting, though.

It sounds hardware related and nothing you'll be able to resolve. Are you still under warranty? If you are I'd take it in.

Heating issues and random shutdowns

Hello,OK so my gtp1000 has been rooted and flashed to cm9.1, performance is fantastic but my tab heats up pretty quick and sometimes the tab shuts down without any warning. Any fix for this?
Sent from my GT-P1000 using xda app-developers app
Install CPU spy and see if your tab has deep sleep.
Then post back.
Sent from my GT-P1000 using xda app-developers app
OK now I'm using cm 10.1 with touchwiz and installed CPU spy and right now deep sleep is at 44%....what does it mean?
Sent from my GT-P1000 using xda app-developers app
Hmm.. Wrong hunch. I thought your overheating is caused by some wakelock at high speed.
The fact that you get deep sleep means unlikely that.
Have to let others chime in.
How about baseband and IMEI? Normal?
Sent from my GT-P1000 using xda app-developers app
OK how to check that?
Sent from my GT-P1000 using xda app-developers app
In the settings, about phone/tablet. You look for baseband, should be JPZ or some sort. Not UNKNOWN.
IMEI is also there in Status, should be 35xxxxxxxx not 0049xxxxxxxx or UNKNOWN
Sent from my GT-P1000 using xda app-developers app
OK both my baseband and imei are unknown my tab is a gsm one so what to do now? How to fix this?

Recover the /efs from backup or restock and make a copy of your imei.

My P1000, flashed from restock to cm-10.1-20130614-HumberOS-p1, became hot after 5-10 usage minutes and is unstable from first minute.
Logcat and kmsg before a sample crash (browser in this case) and last_lmsg after the reboot.
Somebody have same problems? How can be fixed?
Yeah, restock and fix the IMEI issue first.

HTC one battery draining 6% per hour!!

Explain this to me
It is hard to tell by the screen shot, but could be that you had the screen on for a long time, or that your phone was spending energy to trying to connect to cell service?
Ok I'll post some neescreenshots in next few days.which screenshots should I post? Also should I leave power saver off?

Download GSAM battery monitor and post screens from it. It has a very detailed breakdown of where your juice is going.

Is there a app like Google maps that's does the same thing cause I want to be able to use mobile network location without it draining my battery
Sent from my HTCONE using XDA Premium 4 mobile app
Try using Juice defender to make WiFi turn off when your screen is off. Also, if you're rooted you can download greenify from the market. All those little things drain battery fast. :thumbup:

Your battery is fine. 30 min wakelock in 12 h is very good actually

If I turn Google location service on will my battery drain be worse?

I would agree. GSAM says 12 hours since last recharge and you are at 55% battery. I think that is pretty good.
When I turn on GPS or network location I get a wakelock from Google play services or Google "network location" I want to be able to use the features. When I turn on GPS I have to force close one of them or the GPS icon is on the whole time!!

Is your phone hooked up to Google now? Try looking at some of those features, I know for me it was pretty much running the entire time, even if you closed out of it. I mean, it constantly monitors where you are...Also, any type of weather app, widget etc does the same, in my experience.

My battery drains 6% every half hour. I've tried flashing two different Roms from a stock sense to CM11 but no avail. Plus it takes all day to get to a full charge when charging. Could my battery be bad or something I'm not noticing? #noob

When I'm on WiFi for any amount of time makes my battery drain fast with nothing else on (GPS,Bluetooth etc...). I have power saver,sleep mode abd WiFi optimization on if that makes a difference. Dropbox upload is off.

I think you're in the normal range. I have 6.2% an hour today with moderate (similar to yours) use.

Unfortunately the Setting has stopped.

Hye guys..
I need a little help here. It has been day 3 and I cant solve it yet. I received a notification saying that the Setting has stopped when I tried to see my battery usage. Anyone can help?
I tried to restart my phone many times but still no good.
P/s: if this kind of thread existed, please redirect me.. Thanks in advance!

Not necessarily exactly 90%, the battery stats resets at 90%+, so anytime after that is fine.
