[Q] Is Anyone Seeing This Particular Type Of Lag? - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

I'm seeing lag on the phone under a specific set of conditions and wondered if anyone else was seeing this. If the phone has been asleep for more than about 20 minutes, after I wake the phone the first app that I launch, irrespective of what the app is, lags for about 2 seconds before opening. Any less than about 20 minutes sleep time and the problem doesn't appear.
After the initial lag opening the first app everything works fine until the phone has been asleep again for more than around 20 minutes. Then the same thing again..... the first app that I open lags for about 2 seconds before opening.
The problem was happening with the standard kernel, KKA. I've since rooted and flashed AbyssNote 2.3 but kept the standard rom and the problem is still there. Anyone have an clues what might be causing this?

Remember that when the CPU comes from a deep sleep it's running <50Mhz. So as soon as the phone wakes it needs to speed up again. That's it's only the first App. By then the cpu is running >800Mhz.

Two seconds for CPU waking up? It's 21th century.

I totally agree but it's not the dreaded wake up lag that I'm referring to. I really thought Samsung would have dealt with that by now, but to their discredit they haven't either on the SGS2 or the Note.
People who justify the wake up lag by saying the phone has been in deep sleep are clutching at straws. HTC phones deep sleep and don't have wake up lag. This is a Samsung issue and it should have been dealt with by now on phones of the caliber of the SGS2 and the Note.
The lag I'm referring to is after the phone is awake and I launch the first app. There is a lag of about 2 seconds before the app launches, irrespective of what actual app it is the I'm launching.
After that, all is good until the next time I use the phone.

Tried to change microSD card, or trying to use phone without it? Seems like card problem.

I don't have this lag issue on my note. I use abyssnote kernel with interactive CPU governor.

Thanks for the suggestion but the microSD card is not causing the problem. I removed the card and the problem still exists.

I get this lag too guys, sometimes longer than 2 seconds. Very annoying. Also you have to wait ages for the app list to appear when creating shortcuts for homescreen. This happens after the phone has been on for a while after a reset. Its fast from a fresh reboot. This does not happen on the S2.
General responsivness of the phone goes downwards as time and days pass. This does not happen with the S2. Have to reboot every two days pretty much to get the snappiness back as clearing memory via task manager does not solve this.
I'm Using Checkrom with Abyssnote Kernal. Happens with FM Kernal too, so I don't think its kernal related. Don't remember this happening on stock firmware.

occasional clock lagg

hey all, question here. I have noticed this in the last few roms, not sure if this happens in stock, but i have been running cognition, currently 3.04 ( before that 3.02, 3.0 and 2.3b6), Occasionally I notice that after the phone comes out of sleep I see the clock go from example 1:30 to 3:30 or something like that. IS that a bug in cognition? or does the clock occasionally turn off when in sleep mode, and the reason for the lag sometimes be the phone cpu usage is doing some thing when i come out of sleep causing the jump to current time? or whats the reasoning behind this?
thanks.

When the device goes to standby, all the widgets and screen updating apps are put to sleep to save battery. When u turn on screen, all these are refreshed. This is normal.
alright. Just curious, how come sometimes i see the clock go super speed to catch up, and other times it at the correct time? ( I usually dont see it, Ive only seen it maybe 5 times past month)

No clue. Didn't go into so deep architecture I shall see if I can find out how it works internally when I get some time.
Thanks. Anyone else feel free to answer as well.
I am looking forward to your research. I am a techy as well, and not knowing why somethings happen and dont happen when it comes to things like this bug the heck out of me.

As a more visible and more frequent occurrence, load a time app onto ur home screen. You can see it get updated when u turn the screen on frequently.
I think its more dependent on how many apps/widgets need to be updated when u turn ur screen on. I hardly have any on my screen so its a rare case I see the time update.
ok, so let me get this right, your saying it probably happens more often when i haven't used my phone in a while, because lets say I have things that update every four hours, and if the phones in sleep, and they haven't updated, they all could possibly be updating when i come out of sleep because there over due, thus sometimes causing the system clock to jump?
Any one else know anything ?

All that u set for 4 hours to update, get updated but in the 'background'. The 'display' part of them is not updated, and is 'refreshed' when screen turns on.
Hey, anyone else got any theories or updates?
I'm using ultimate Rom, newest version as of a couple of days ago.
Just noticed this about 3 times in half an hour or less.
Interested in learning why I will see my clock jump from like 2:13 - 2:17 instantly at times when I come out of sleep...
a google search using different words found this :
http://code.google.com/p/android/is...ec=ID Type Status Owner Summary Stars&id=9524
Are there any devs here that could explain or potentially fix this issue ?
Reading all that worried me, thinking hey, maybe my alarm clock isn't reliable either...
I had this issue when I was running 2.1 stock. I haven't had the issue since flashing 2.2 (have used both cog 3.02 and andromeda 2.0).
Your link also seems specific to 2.1, and I believe is a known issue coming out of 'deep' sleep. I had some luck with app called 'load monitor'. It's free and has a setting I think is called prevent suspend that doesn't allow phone to go into deep sleep.
Not sure if re-flash might help since what you describe shouldn't happen running 2.2
i897 running Andromeda 2.0
Okay. But what are the chances of me repeatingly getting bad flashes? Ive been on cog 2.3b6, 3.0 , 3.02, 3.04 snd now ultimate rom. Sometimes i wont see it happen for weeks. Other times ital happen a few times in 30 mns.

Oh and reading through that link you see tons on 2.2 have that issue, not just 2.1
Sent from my GT-I9000 using XDA App
Yeah not sure. Really thought was general 2.1 issue, not just on captivate.
Try load monitor. I forget the setting there, but it'll prevent deep sleep. That or you could try app 'no led' and send yourself an email before going to bed (when active notification that app prevents deep sleep too).
Sorry those are lame options that'll affect you battery life to some degree. Perhaps there are better options posted here but you'll have to dig for it.

Lag + occasional freezing

Sup,
I experience lag frequently. A lot of times I can feel something in the phone spinning or vibrating as it comes out of the lag. the vibration isn't as rigorous as the notification vibrations. Also sometimes it will lag but not come out of it and completely freeze then restart itself. The freeze/restart seems to happen when surfing the web.
I'm running serendipity 7 build 2. Its happened on serendipity 6.x also. Not sure if its rom related or just my phone failing. Anyone experience this?
I should add that I have 9.31gb available out of 13 total.

I've had similar lag and reboot issues on Serendipity 7 don't know why, but you can always just try another ROM and see if the problem persists.

A couple things that come to mind, one is the vibrating sounds like something is F/C'ing. Take a look at your applications, what is running, do you know what you're trying to run when it vibrates? Also take a look at your system resources, I get lag if I have too many items running and system mem gets too low
"Most" issues tend to be software related so that is where I would focus my attention. If all else fails, reinstall your ROM

It happens the most when I am browsing the web. I have been using xscope for a long time. First the free version and now pro version since it was faotd on amazon. It happened with both versions. although xscope could be the problem its not the only culprit cuz it happens when im not browsing the web also. Maybe I should install logcat and check it out after the next time it happens...?

Lag & auto shut down
My captivate with serendipity 7 initially seemed perfect. But after a couple of weeks of usage, it started becoming slow. I face quite a bit of lag, automatic shutdowns and poor battery. I do have a few apps running in the background, but there was no lag when i was using cognition 4 or CM7. When my phone shuts down automatically, I have to take the battery out and put it back in to restart it. Holding just the power button doesn't switch it on.

Not to be an ass but you sorta jacked my topic. I'm not experiencing sleep of death. My problem has to do with the phone freezing then restarting itself.
Just don't want more posts further veering of course and hindering a solution for me. Thanks.

Permanent and annoying issues with CM7

Hello,
I've been using Cm7 latest KANGs since months, they're all good but there's ALWAYS been problems in every cm7 build that makes me hate this phone when it happens.
The problem is that they happen randomly with no apparent explanation!
problem #1
almost every week it happens that the phone drain battery very fast and gets a little hot. The reason is "suspend" process running wildly in the background.
What is it and why doesn't happen always? Solution : reboot, after it drained half your battery
edit : now "mediascanner" took the place of suspend
problem #2
every 3-4 days if you never reboot the phone it gets to a point where its slow and slightly unreactive. When you surf with Opera you notice a struggle to process data like something is using the CPU, the reality is that nothing is.
The worst part about this is when the phone is in that state and you do something that involves a cpu process you hear a noise form the speakers like an interference it's very difficult to explain. If you happen to listen to music in this state everything that you do makes the music lag like if it restarted every 1/3s of a second, like when you try to playback some video from a source that has a slower reading speed than the video bitrate itself. A jerky playback.
Solution = reboot.
problem #3 every month the phone (even on silent mode) "screams". :| that's right, from the speakers you suddenly hear random "leaks" of loud and high pitch sound things for NO REASON.
"problem #4" the front facing camera is just bad it doesn't adjust to the light with auto exposure compensation. It has very bad banding and digital noise things on the image. I thought it was a driver problem in cm7 but it happens in stock too. This problem didn't happen in the first nightlies of cm7.
Are those bugs reported?
I'm currently in problem 2 and I'll just let it do its thing just to see how funny the battery graphic will look. In 6h runtime I have "suspend" using the cpu for 30minutes and going.
I tried every kernel.
i have the same problem as you with suspend i dont know what it is, but anyways my battery is not that bad after 16 hours is still 58% medium usage.
we can try asking temasek if he has a clue.
I also have problem #3
very strange, happens sometimes even when the phone is on silent, and it's been sitting on my nightstand for 7hours without me using it (plugged in)
it also happens sometimes when it's not plugged in and I'm just browsing the web
(seems to happen more often when viewing video's)
What annoys me most its problem #1 . It's just unacceptable to have something for no reason draining your battery when you phone is sleep mode, even worse when you don't when it will happen!
#1 - I rarely have this issue but it doesn't drain my battery.
#2 - I don't hve this issue
#3 - I don't hve this issue
#4 - I use LG modded camera so no such issue.

Now I have it and I can't get it to go away!! It drains battery at about 10% per hour (without touching the device). What kernel are you using?
Can you link me the camera mod?
Got another for the list!
BBC iplayer !
On both the app and the Web page it works fine through the interface, the intro to your TV program works fine, then you get into the program and the picture is just pixelated rainbow mush! Lol!
Weirdly if you minimize the program and then resize the image it's fine!
What's that all about?
another one:
( I think its with every android version above 2.34)
if there are too many apps moved to sd card (about 50) phone works only till first reboot. once shut down and turned on again, phone keeps on rebooting. only thing that helps is putting sd in pc and delete some .asec-files from .android_secure-folder.
I had #3 before, I think it was around Temasek kang 1x.. After a dozens of flashes, I forgot it ever existed.

There's another one too which is important to save battery life: sometimes the wifi connection doesn't start until you go into the wifi settings. Meaning that if you are within the coverage you won't be connected to the wifi network until you go into wifi settings. This will drain battery because the phone won't turn off the eventual 3G active connection

BTW this phone has the worst ff camera, just bad bad bad quality
haha...the speaker scream at night....
just flash CM7 (Alien Revolution) this morning,
only some minor things found:
1. have to remove the latin.apk manually to against force close
2. can't use the original screen capture (HOME + POWER),
use the option by long press the power button for replacement
3. while playing "Let's golf 3", it got force close
clear the data of the game and it's solved.
4. 2 hrs before, the phone signal suddenly drop and disconnected...
just reboot and see whether it happen again...
Hi Temasek.. will this camera mod work with MIUI roms?

I have another problem on using CM7, it's the HDMI connection. My phone doesn't displayed on 1080p mode, pic quality is awful (my LCD TV is full hd capable).
And when I played a movie and throw it to the LCD TV on landscape mode, it displayed only for couple of seconds and then blackout. My phone continued to play the movie though. This is not happening in portrait mode.
On Optimus 2x stock ROM, it is possible to select hdmi resolution. How to do that in CM7?
Thanks!

Problem #1 happend to me once, i was on ETaNa Kernel 0mb (i dont know wich version) and a Temasek Kang (think it was 61)
Never happend again. Now i am on ETaNa 32mb 18th Feb. and Temasek Kang 66, everything works fine for me.
I think the battery draining issue was just a bad RIL now battery seems as it should be.
I still have problem #2 though and I can't believe I am the only one experiencing it!
I made a mistake because I was powering off the phone at night in the last month but now that I'm keeping it on at night I can say it happens after 1 day of running time.
Basically when you start using it the second day the phone becomes unresponsive, go launcher EX keeps reloading icons very often, it takes sometimes 2-3 secs to open an app after you press on it , Opera keeps getting shutting down if you check another app for 1 second, when you go back you have to wait 6-7secs for it to restart. The situatios stabilizes itself a little when you keep using it (still not that snappy like at boot) but then goes back to the same sluggishness.
Juicedefender shows in the logs that "memory is low" and for how the phone acts it does look like it but I always have 80-100MB left and even if I kill every service running the sluggishness is still there. SO what the hell is causing it? Could this "suspend" be responsible for memory leaks? Again what does this suspend do?
Here's a screenshot for today only after the overnight recharge.
And of course the phone died while I was charging screen or phone wouldn't turn at all, apparently it charged to 56% and then BSOD
Just to make sure, am I the only one where suspend uses all the cpu?
i have also tryed cm7, its nice and stable but a little bug which forced me to change the rom, go launcher always restarts and i have to force close it and whenever i put some movies and images in sd card gallery doesnt updated it and shows old files only, thats y i changed my rom.

[Q] Galaxy NOTE SOD problems.

My brother's galaxy note have been facing serious sod problems since he bought the phone at Nov 2012. After he faced it the 1st time , he sent to SC and got it back. After 1-2months the problem came again and he asked for my help. I persume it was because the malaysian firmware of the ICS was somewhat unstable from what i read from forums here and there. So i changed the firmware to JB duno from which country when it came out in MAC. After a week or so. The problem reappeared . So I just decided to root and chnge the kernel and also the ROM. Changed the ROM to a stock rom and a kernel. Still the problem persist. I'm out of options. Went to the ****ty SC and the idiots just factory reset the phone and give u back. BUNCH OF RETAR*S . (sorry for my languange)
Hope someone here may help me out with my problem. Thanks a million :laugh:
Check all the apps you have installed maybe you find the bad one whose causing it as you have mentioned it comes after sometime of installing a fresh rom and have you tried any aosp rom maybe that will fix the issue

I just installed an aosp rom (PA) and I hope it fixes the problem. Well I've seen the amount of apps installed in the note and its jst a quarter the amount I have in the Galaxy S2 and my S2 works like a charm. The note has been giving me headache ever since I got it from my brother. Hope this does solve it , if not I guess its something else maybe hardware
Phone sod twice on paranoid android. FML! Guess im visiting SC tmrw again.
Same problem with me..
My Note 1 has SOD since 1st time bought it..
be patience to install JB --> still SOD
change kernel to SpeedMod 5.3 --> SOD again
change kernel to PhilZ --> sometimes SOD
I have read many information that related with SOD in galnote 1, my opinion it is related with hardware too.. sometimes
or it is related with kernel... it can not wake from deep sleep..
anyone have another better suggestion to cure this ?
if u're using pure stock rom still facing the same problems then definitely is hardware issues!
if ur device still under warranties suggest bring to SC ask them do a thorough check on it n let them know what's going on actually...
Yes, I use stock ROM still has SOD,
so it's hardware issue for sure...
but I will keep the phone for now because sometimes SC doesn't give solution to this..

I too get this SOD once a week on my GT-N7000
Phone status when this happens:
stock JB(earlier ICS), non-rooted, data connection, wifi, GPS, bluetooth all disabled. Battery mostly above 80%.
Gmail, Google+, Facebook and all other social n/w apps disabled (yes, i am an oldtimer )
During SOD, if a third party calls my number, he hears it ringing, but my handset is dead as dodo (quite dangerous as the calling person may think i am not answering it)
i used to get this when it was on ICS and still getting it after i upgraded to JB.
Most of the time, SOD occurs during wee hours in morning ( i used battery monitor app that logs battery stats every 10 minutes to check the time when this happens).
Sometimes it occurs when the phone is in my jeans back pocket. phone needs a 10 second press on pwr switch to restart it.
Turning off the "power saver" mode seem to reduce the probability of SOD.
i have taken this phone to SC and they re-flashed the JB.
i told the SC chap that i have already done this and couple of factory resets, but he said that they do "much more" than just re-flashing through kies like calibrating camera, bluetooth )
does anyone in the know, know if this is indeed true ?
Thanks

updates...
After 2 days of re-flashing at a samsung authorised service center, i got SoD 2 times in a period of 12 hours.
once last night and second time when i was traveling to office.
Last night i installed some bare-minimum apps back after waiting 2 days for any SoD to happen in "stock" condition.
Well.... i did not pay 30K to use the GNote as just a phone, so installed some basic apps (Battery monitor, Bangalore BMTC, RealCalc, GPS Test, ES File explorer and a first time app StatusLogger)
phone went dead at 1:00 am in morning and as usual there was no wakeup alarm.
phone was warm to touch when it was lying dead. The battery which was 96% at 00:30 AM had gone down to 54% at 7:00 AM.
Status logger did not show any loss of GSM signal which might have resulted in phone transmitting at higher power/hunting for signal etc.
The "radio" seemed working, because when i made a call to the dead phone from my landline, i could hear the phone ring instead of expected "phone is switched off" message i was expecting.
So this has to do with application processor going in some infinite loop.
Uninstalling all apps is NOT an option.
anyone know if we can establish any debug connection to phone and know what the hell CPU is up to in this situation ?
any processor logger that will periodically log all the processes running on phone ?
SOD resolved... not a single one since 6 months.
Hey guys, just wanted to share this info with you, I had SOD's like anything and did all freakingly possible things right from flashing roms to kernels, speed up CPU, banging my head in front of the dumb witted morons at samsung service... to get rid of that pain. What helped me was an app called "WAKELOCK" by darken which is merely 72kb in size but works wonders, not a single SOD after that. What u need to do is.... it has a list of presets that makes sure your cpu stays up. You need to select the preset called "partial wake lock" which is at no. 4, and viola...
It ensures that the CPU is running. No SOD ever after. Also, you need to make it autorun on boot from the options. Yea, it does eat up batter a bit more but its definitely manageable. I still need to charge my note only at night.
Just to be sure, I uninstalled it and guess what, SOD returned. So, do try it, I hope it helps...

Possible GPU failure?

So recently I've been running the smurf kernel to play games like pubg with OC. But all of a sudden my note began glitching and caused graphic glitches. I thought that this might just be in game but it happens when I exit. When I exit usually the display just goes black but the digitzer underneath is still working. Any ideas on what's going on. Oh also. I thought this might be a smurf kernel glitch so I switched to notorious but it just repeats. This happens at random too . Screenshots.

Does it happen in other games? Graphically glitches such as that typically means that the GPU is not capable of process the visuals at the settings requested and bottlenecks. At least when it comes to PC.

GPU artifacts. Your phone's GPU is overheated.
It doesn't happen in other games. Also, are you sure that it's just an overheating issue than a defect?
Try reinstalling the stock OS back onto your device. There is a chance that the GPU drivers may have gotten corrupted

Most likely. The common factor is artefacts during PUBG. Since the issue doesn't occur during other intense games (if you've tried others), then PUBG is the factor causing the issue.

Ok so an update on the situation. Switching to a different kernel doesn't appear to help at all. In fact the situation can get a little worse at times. It doesn't happen instant but can happen at random times. It's spread to other games but only if I play the game for a while (2 hours usually). Honestly don't know what to do at this point. Usually when you overheats it downclocks automatically right? So I doubt it's overheated. I am about to wipe everything off and start new. Maybe then my problem will disappear. If anyone can please give me the direct cause of this error I will be forever grateful

I would do a full wipe, go back to latest stock firmware with Odin, and then test from there. If the problem persists, then I think it's safe to say it's hardware failure of some type, which would require repair.
Any updatess?
Yes, So I have gone back to stock and have played PUBG. The artefacts dont appear however sometimes you catch a glimpse of very minor glitching. Now I wonder whether this is due to the fact that my note has a low GPU bin of 2 out of 15 (I think). I have switched over to a new ROM and it appears that the RED flashes of death were temporary and maybe gone for now. I will report if it repeats itself.

Thanks for the update, glad to hear things have improved! PUBG is kind of buggy overall, so those new minor glitches could possibly just be the app itself. Keep testing and see, but hopefully everything goes smoothly

Decent write up of how to fix some of PUBG glitches and lag. I haven't tried that game but could possibly help.
Ok everyone! I believe the issue is solved!. A reflash of the stock ROM appears to have fixed the glitches. Even on low battery it doesn't seem to affect the device so I'm going to put it down to corrupt gpu drivers. Thanks everyone for your help, y'all have been awesome.
Are you doing Dream UX for the galaxy tab s2. If you are, I have a SM-T813 and I am willing to test on it since you do not have one for this device and I don't expect for Samsung to release 8.0 Oreo on it.
Please and Thanks
