Occasional Unresponsiveness - Galaxy Tab S2 Q&A, Help & Troubleshooting

My usually rapid, excellent Tab S2 is occasionally unresponsive when I wake it and I was wondering what is the best way to troubleshoot this?
It's running the latest firmware (non rooted) and occasionally on wake it freezes for a few seconds until I close the app then is slow for a couple of minutes. A reboot normally sorts it.
I've been tempted to do a factory reset but can't be bothered with all the hassle of reinstalling and was hoping someone would help me learn how to get to the bottom of these sort of problems.
Any help would be appreciated.
Thanks

Flashing Green Screens while screens load

So this was happening before but I factory reset my phone and now after about a week and a half it's happening again;
everytime i either go back to the previous screen, or while i'm on a loading screen (noticed it a lot with Netflix) but i get these green pixely squares that flash on my screen... this a known issue with the version? or should i take my phone back?
I'm not really sure how to better describe it...
Have yet to experience that, had my unit for over 2 weeks.
Take it back.
-smc
I have the same problem with mine had it since it came out?

I've had the same issue. Started happening within 2 weeks, but more recently it hasn't happened much. A battery pull always fixed it for me. I'm experiencing random reboots when the phone hasn't been touched for ten minutes, this is more disconcerting to me
I haven't noticed it after a reboot for a couple days now...
But i do remember almost directly after it first happened (before i did the factory reset) my phone started doing the whole random reboots too. That's when i read the post about fixing the camera and not using the assistant backup/restore functionality when you activate the account...
I thought it had fixed all the issues but seems they're still there just, less sever...
Rebooting the phone (temporarily) fixes the issue for me
[sent from my droid]
I swear, after using the camera this happens. Until I reboot I get some kind of green checkerboard whenever the screen rotates or changes
Same here. Every time I use the camera and sleep the phone it will get hot and drain the battery. Waking the phone gives me green pixellated images and serious slowness. Battery pull after taking pictures is the only way to mitigate it...for now.

So this seems to be a common issue... has anyone been able to talk to motorola? is there an update coming out anytime soon to get it fixed? or is it just a hand full of bad phones?
smc, have you still not experienced any of these issues?
can you try seeing if it might happen after some of these scenarios listed in this thread? would be greatly appreciated!

My Note Is Driving Me Insane. Can Anyone Help?

I'm not sure if my 2 month old Note has had the following problem since day 1 but it's been doing if for a long time now.
The problem is there with a stock standard rom and any of the other custom roms and kernels that I've tried. I'm currently using Rocketrom with Speedmod kernel. I've also used Checkrom and Abyssnote kernel.
If the Note had been asleep for about 15 minutes or more when I wake it up then try to do anything like opening an app, closing an app that's already open etc there's a 2 to 3 second lag the first time I try to do anything. Everything is then normal until the next time that the Note has been asleep then it's the same story again.
Can anyone give me a clue as to what is going on here? I'm starting to think that it's hardware related, but apart from this problem the Note functions perfectly normally.
Also, if I have a CPU monitor installed, like URsafe CPU Monitor, when the lag is happening the monitor shows that the CPU is working hard.
Help please!!!!!
Does this happen after a complete hard reset with no apps installed?
Does this happen on Stock ROM?
Are you using WiFi?
Sounds like WiFi is sleeping when the screen is off, and either it is trying to connect and/or some app is wildly trying to connect using it.
Try seePU++ can tell you what the most active app is, but IIRC you have to pay for that that feature. There may be others.

Yes, it happens on stock rom with no apps installed. I'm not totally sure what you mean by a complete hard reset. Can you please tell me how I do that? I'm willing to try anything to get rid of this problem.

The problem still happens with WiFi disabled. On top of that it doesn't matter how long I leave it after I wake the phone up till I try to do something like launching an app. The problem is still there the first time I do anything with the phone.
I have rocket rom and sometimes when I turn on the screen the screen wont work. The physical buttons work but the screen is wont respond to touch.
Turning on and off the screen fixes this.
Very annoying.
Makes me appreciate Apple more.

Do a clean stock ROM with no root or anything.
Do a factory reset and erase your USB storage as well (i.e., tick the option when you're factory resetting).
Remove your microSD card.
Now, does the problem still occur? If it does, get your phone exchanged/repaired. It sounds like a hardware problem.
What you are experiencing is perfectly normal.
I'm getting the exact same issue. When the phone is not used for a long period of time, is then unlocked, opening contacts, sms or the menu takes a good 2-3 seconds.
It's really annoying and it's a delay when 'waking up' the phone.
Supposedly this issue should be fixed with Ice Cream Sandwich, so be patient and this bug should soon be gone...

Just not getting that myself. I am not terribly patient, and generally the most I have to wait is a second for an app to respond after waking the phone, and that is not often.
Stock unrooted HK version, never seen anything like that delay, mine works instantly on waking

I dare say this is not normal, the only time there is a delay in opening the dialer/contacts application is when you initially boot the device and have both of those running for the first time subsequent runs have no delay what so ever on my end ( when i still had the note )

If this is normal it's incredibly bad that Samsung would design something like this. The wake up lag is bad enough let alone this. Can't see how it can be normal though. My SGS2 didn't have it and some other users aren't seeing it. I think I'll hang out for ICS and see if it goes away before I take any further action.
Strange issue, seems it occurs for some but not all...
Once again, I unlocked the screen after 2 hours of no use, when pressing contacts, there was a 2 second delay and when attempting to call someone there was a good 2-3 decond delay...

Despite being my first Android device I have come to accept that this is normal for this OS.
Unfortunately I have become a big whiner on this forum because of this same issue.
The day before yesterday there was an update on the kies ,LA4,after updating it felt a bit faster overall but the wake up and the incredibly annoying Contacts lag is still there.
I myself am not any particular OS follower or a fanboy of any certain brand for that matter.
So I'm stuck with Android for the time being, since I don't like both iTunes and izunes dependency, besides no big screens there.
However I suspect that this is an Android thing, as far as I know Android is based on Java and Java is known to be laggy,so until a very powerful CPU is available for mobiles, for me its either live with it or Leave it !! and since there is no alternative for now will wait and see how good ICS does and decide accordingly.
I'm on stock ROM and unrooted.
The Note seems to do this once or twice but when a program/app has been opened once it usually reopens them instantly.
This morning when turning on my Note for the first time, there was a few second delay when attempting to call someone, another delay when opening contacts and another slight delay when viewing sms messages.
However, the second time I attempy to open something it's usually immediately.
There should not be ANY delay when opening programs/apps and Ice Cream Sandwich should fix this wake up issue which some users such as myself am experiencing.
It's a shame, really since I'm getting no other lag/delay. The phone is super fast in every possible way, only sometimes it's a little slow at waking up!!

[Q] Galaxy Note GT-N7000 crashing regurlaly how to find out the culprit?

My Note has started crashing regurlaly, I have had it since release and have a lot of software on it. I am not sure when it started happening but it is definatley getting worse as time goes on.
Is there any log file or event browser that can be installed to tell me what is causing the problem?
When I say crashing I mean literally crashing dead not a force close. I either find it in my pocket turned off and then have to hold the power button for an age to turn it on or sometimes it is sat on the desk and I suddenly hear the noise it makes when it re boots.
Any suggestions for finding out what the problem is that don't involve uninstalling software until the problem goes away?!
Thanks
Have you tried better battery stats? It gives a list of processes that have been running.
Definitely strange - do you have an anti-virus program you can run to see if it can help?
That sounds like a Sod (Sleep of Death) issue that's been reported many times b0t with no definitive solution of yet..
Some said changing modem helped, others with changing kernel or even ROM but no consistent solution across all users
Try to fix permissions through advenced menu in recovery but am afraid there is not much I can help with

Omfg, I don't think your alone cause I have the exact problems at times when the note just freezes up and you have to manually boot up...lets hope the upcoming pics update will solve this ongoing problem... I'm getting this about 3-4 times a week

it is starting to make the phone a liability as I keep finding it turned off in my pocket!
Is there no software that will produce a crash log of some sort?

this is driving me nuts. The phone is unusable.... is there no possible solution??
At this point I will try anything. It crashed during the night on Thursday, didn't restart and so there was no alarm and I was late for work!
Please post your current configuration Kernel, Anti Virus program if any, undervolting, overclocking ?
By any chance are you using easy task killer... if you are just change the auto optimize to nothing - I did that and it stopped sleeping...if your problem is persisting then you could just do a factory reset and use default settings...

My note recently started crashing as well, whenever i turn on my mobile data plan or the wifi it will crash right away
However this is ironic because when ever i put my mobile in charging mood than i have no problems at all.
So im thinking ,is this the battery problem or the software problem?

battery problem.Try to see what is the output of ur battery in full charge by messure it with electric potension meter (sry for bad english).
If the meter say less than 1850mAh in full charge than u need a new battery.

S6 unresponsive

My S6 randomly becomes unresponsive, it seems to happen most while charging. But when it does, the power button doesn't do anything. The only way I've found to get it working is to hold down power and volume down.
Only started happening after 5.1.1 update.
Full stock..
Any ideas what's causing it? Anyone else experiencing it?

Factory reset!
Same issue. Tried factory resetting and the problem still persists...
Same problem here. Not necessarily when I charge. Hangouts is a wreck, takes forever to launch and when it does, it lags. The keyboard also sucks and lags.
Random app crashes, this phone is wearing me out. Not sure if it's hardware, or if I should just root and send it back.
Edit: it also switches to 4G when there's a great LTE signal and it will NOT switch back unless I toggle the network in settings.
5.0.2, rooted and modified ram managment settings from the thread in general discussion. phone is slow af after an hour or two of use, a reboot fixes it temporarily but it's still consistently terrible. would love some kind of fix for this :-/

My s6 is fine. No lag and responsive while charging. Didn't have problems while on stock but I'm currently running XstreStoLite Odex

Have you tried without using the mod?
Make sure it is not an app causing the issue for anyone who has this problem

Severe lag when using after its been off for a while.

My Galaxy Tab S2 seems to lag for a couple of minutes when I first go to use it. This is after I've left it just on the side for a few hours or overnight (not from boot-up).
When I try to open an app it freezes then a few seconds later it does what it was supposed to do then it freezes again. I force close all but this doesn't really help until I've done it a few times.
I wasn't sure if this was something to do with the built in auto Wifi off so switched that off and it seemed to improve it slightly but it still happens. I tried using some auto WiFi off apps instead but they didn't even work.
After this first couple of minutes it then works fine. I uninstalled all apps and it was ok but it wasn't before long it came back. It wasn't particularly noticeable after any specific app.
Is there a way to analyse what is causing this lag in the background?
I'm experiencing the same problems. I wonder what could be causing this?

I've noticed this for a long time. If you use a system monitor you will notice that the Disk reading will be at 100% for some minutes, leaving the tablet unresponsive.
I don't know how to identify which apps are doing the reading.

First thing I do now is kill all running apps but still get some lag. A persistent app apparently.
