[Q] Galaxy Note not waking up?

I can't put my finger on this issue I've been having with my Note.
Don't get me wrong, this device is a godsend!
The problem I've been having is that sometimes when I take my Note out of my pocket and try to press the unlock or menu button it doesn't show anything on the screen. I've read about people having issues with delay before it pops up, but it doesn't pop up even after 10 seconds or a minute, it feels like the device 'hangs' or doesn't want to wake up. The only way I can turn the phone on again is by pressing the unlock button for like 10 seconds and the phone reboots.
I thought it was a problem with Green Power, I thought it maybe had issues turning off the wifi or data when the screen was locked and that the service would cause the OS to crash or 'hang'. When I look at my battery history after the reboot it shows that I lost a significant amount of battery (5-15%, depending on how long it took for me to 'discover' the crash) and there's a 'jump' in the graph.
Things I've tried:
Stock rom - problem persists
Different kernels - tried all the kernels available in the market including stock, problem persists
Add a bit of paper between back-cover and battery (to make sure it doesn't lose contact)
Checked if there was dust between battery connections
Tried different sim card
Tried disabling wifi and data all day (mysteriously persists)
DIfferent governors (ondemand and interactive) (the phone reverts to default governor after the forced reboot, normal? i have my phone set to interactive on boot, but somehow it skips that after the forced reboot)
I've attached a picture of the battery graph. According to the stats there's a 25 minute gap where the phone was 'stuck' and you can see that the screen was on and active for that duration.
There are NO funny apps running in the background, this is is a clean install with some standard Samsung apps frozen.
tl;dr version: phone randomly won't wake up; battery loss after forced reboot;

I might have found the issue myself. Now when I come to think of it, I think it always occurs after I've been in my car for like a 30 min drive... Maybe the phone is having trouble switching networks? Anyone know what might be causing this?
Or better yet, how can I research this issue? Can I enable some logging somewhere to track this?

I had the note for about 10 days and today, about 1 hour ago it happened to me for the first time. I tried the home button to wake the screen but nothing, tried the power , nothing and holding the power but nothing happened. I had to pull the battery.

I had this problem in the beginning, but no more.
It's one of two things, in my case. Restoring apps (with data) from Titaium backup, or SetCPU or both. Do a factory reset, reinstall apps without data. If using setCPU, disable it for a while to see if it happens again. It's been over a week and the problem is gone.

I was using System Tuner instead of SetCPU to freeze apps and change governor, maybe I've just been using the wrong app? I deleted it just in case. Will see if the problem persists, thanks!
The nasty thing about it is that it seems to happen randomly (but it most likely doesn't) and is pretty rare (happens once every 3 days).
Still, I don't like the fact of not being available for X amount of time, even if it's 30 minutes.

I'm on stock room and unrooted. Like I said first time it's happened.

i've had the GNote since 4 days now , and yesterday same thing happened as the device was in my pocket and i couldnt wake it up at all , battery pull solved it.
im on stock , non rooted

I can't believe that we are the only ones with this issue. Anyone else? OR better yet, how did you resolve it?

Dont know if this is the same issue as the streak had, but with the streak if you kept it your pocket with the screen facing your body this would sometimes happen. Flipping it so that it that the screen doesnt face your body in your pocket solved this issue.

Thanks for your reply. I did some research, and apparently it had to do with static being built up in the screen from wearing it towards your body in your pocket.
This issue was that you couldn't swipe the lockscreen cause the touch screen wouldn't respond. The problem we are having is that the screen won't even turn on and that the system locks up.

Same issue here with my 2 days old Galaxy Note, that's how I found this forum. In my case it went from not waking up occasionally to every time WIFI was ON (I did some experimenting with settings to see which one could be the one causing the problem). But then...occasionally it would not wake up even with WIFI OFF: very annoying. And this is my first Android, so I didn't have any custom anything, pretty much same as out of the box when I got it The only solution was to reset the handset. And definitely has nothing to do with having it in my pocket as I don't carry it in my pocket. Rang Samsung, they told me it was faulty, I returned it. Now I'm concern the next one is going to have screen issues? As so many people complain in this forum? we'll see.

My issues have been resolved after flashing AbyssNote 1.4 and when I stopped using System Tuner. I've started using Voltage Control instead and now I'm not even having problem @ 100Mhz undervolted 50mV from stock.

Same problem with my wife's Gnote, totally stock, just a small handful of apps installed. Happened twice, about a week apart.
She does a lot of travelling, maybe you're right about that. But it happens after she gets home when it's still OK.

Had the same same issue twice in two days and had to do a battery pull, just did a master reset and re -installed the applications manually, so far so go.
YOu guys think its a hardware or a software issue?

Hmm.. Happened to me too about three times in the last two weeks. I am on stock rom but rooted, and running Green Power. Hopefully samsung will fix it in the next updates. Seems like a software bug to me. Maybe not enough juice when in deep sleep?

Hello
its the problem of your kernel. try Abyys 1.4 and use XDA Superpower to adjust the CPU-Frequency automatically

It's very well possible that the stock kernel has faulty settings for the CPU. Haven't had the problem again with AbyssNote 1.4 and Voltage Control (even with custom cpu frequencies)

I just got my note today.
Battery in, turnt it on a few mins playing around.... the problem started
and hasnt since stopped...
Anyone tried contacting samsung about this?
software fix or hardware issue ??

at this point we're just guessing, there haven't been any official confirmations of the problem as far as i know.
But if it's so accute that it keeps happening all the time you must have a faulty device.. call samsung ?

Screen becomes purple

Dear All,
I recently bought my phone and i am trying to get used to its big screen but otherwise i am fan already.
I was playing a game and suddenly my screen turned purple, initially i thought it was the games graphic but after closing it the screen itself was purple. I restarted my phone and the screen became normal.
Is it something serious?
I am still under my seven days return period and i can cancel the contract.
Thanks

i too faced the similar problem. After restarting the screen became normal. Anyways this may help. Go to 'Display' > 'auto adjust screen power' and uncheck it. This should solve the problem.

So that means its not a hardware fault?

Do not fear, it is not a hardware fault. Its potentially a power saving glitch !!! Your device is not faulty. Relax !!!

Same thing happened to me and I ran to XDA to search and found this! I'm a bit relieved that it seems it is a software issue, but I don't have screen power saving on and I turned off all power saving options.
I started up Gameloft's GT Racing Academy and thought it was some weird game bug, but then after closing it my homescreen was also pink/purplish.

I have a similar problem but it doesn't turn purplish after playing a game. With mine, when ever I wake up my GNote after an hour or so, it will start off green but slowly fade away after a few seconds. One person suggest it could be a screen fault and to return it. But after I disable the auto screen brightness, it has improved (still getting a green coloring when I wake it up but take less than 1 second to get back to normal and I can live with that). But I never had to reboot to get the screen back to normal though. It could possibly be a bug with the game.
If it only happens with one game, it will more likely be the game that is causing it. But if it is happening with every game, I would be a bit more concern.
If you got a custom kernel or custom rom, try a different rom or re-flashing the kernel/rom. I read on a few other threads that by re-flashing, it fixes some problems.

It was happened to me yesterday when I am playing GT Racing game. I switched off and on again then no problem.

Same game it happened to me on. The screen was fine before I started the game, but once I got into the game everything was covered in a purple hue. I wonder if it is that specific game that might cause it, because I'll delete it and never go back.

This has just happened to me while using Google Talk ... Everything went purple ... When switching back to the home screen, icons that were orange are pink ... Not a good look ... A reboot solved it and I feel a tad reassured after reading these posts that it's nothing major ...

Pictures, pictures, pictures!!! Do a hand swipe when you see it to capture a picture!!!!! It happened to me too and I forgot to take a damn picture!

same problem after upgrading to ics
My screen works perfectly on GB rom but when i upgrade to ics it turns purple. you can actually see the moment it turns purple when turning on the phone and the samsung logo appears.. it is white for a few seconds and turns purple. i have tried all the suggestions i have found in forums or youtube but nothing solved the problem. i have also tried many different ics releases but same problem. only when going back to GB it becomes normal again.
anyone has a suggestion?

[Q] random reboot/mms bug?

Hi there,
just wondering if anyone else are having issues of their phone randomly rebooting? does anyone know of a fix?
also, sending photos as an attachment does not work. in order to send a photo to anyone on your contact list.
found a work around by going through gallery and sending it directly from there.
if anyone know of a fix for either issues. the help would be greatly appreciated.
Thanks,
kevin

I've had several random reboots. Oddly enough, they usually occurred overnight when I wasn't using the phone. I would hear the vibration on my windowsill and saw it was rebooting. I did a factory reset yesterday and while in the midst of setting everything up on my phone, it rebooted again. I thought that maybe there was too much going on and it overloaded. But last night when I was out and not using my phone, it rebooted again. I'm gonna have to go to Verizon to swap the phone.

It keeps happening on mine, but almost always in the car while attached with BT. I'm wondering if BT has something to do with it, in my case.

Same thing
I am also experiencing the issue specifically at night. I have yet to actually have it interrupt me in anything but its still a concern. Just curious about whether for those of you who are experiencing it are using the Assist app or Android Assistant?

I only use the Assist app for when I'm in the car. It's not setup for night time. I exchanged my phone at Verizon today and so far so good. One of the employees tried telling me that the reboots could have been because I had Better Battery Stats installed on my phone and the battery saver apps can conflict with the OS. I blew his mind when I told him that BBS wasn't a battery saver app and simply lets people know about specific wakelocks. Seemed like no one there had any idea this phone even existed.
For the reboots, I guess tonight will be the big test.

It happened again to me this morning as soon as I got in the car and it connected to Bluetooth. Once it reboots, it's solid.

Please report back. I have gone 24 hours without a reboot with no changes to the device which is a first. If it doesn't have a Samsung or Apple logo no one seems to care anymore.

I can't get Assist to work at all. I typically listen to podcasts in the car and when texts come in I get a notification sound but I've never had one read to me. I disabled Assist to see if this was the cause of my Bluetooth reboots, and it's not.
With Assist disabled entirely, each time my phone pairs with Bluetooth it connects but the moment I start to play something it reboots. It's very consistent.

Just wanted to let everyone know that I haven't had any reboots with the new phone. I exchanged my old one for this one on Monday and so far everything's been good.

I have now had 3-4 random reboots that I have seen. I have also witnessed a complete lock up of the phone. I will be heading into Verizon today to exchange my phone.
Just wanted OP to know more people are having issues.

Same here and wondering if that's "Normal" too...

My Moto X turns off at night during charging.

Random reboot

Has anyone else had this happen? Mine did and there's a big gap in my battery usage. I'm singing l assuming this will get fixed when they post the factory images considering the N9 has had 4 updates so far.

Happened today while I was on youtube, so far only once. What do you mean of big gap in my battery usage? Did the battery % decreased after the reboot or are you referring to the battery usage graph? On mine the usage graph restarted but the battery % was a continuation..

Yes it did here's a screen shot I took. I had a brief one earlier but this one was worse.

Phone rebooted today when i received a video message in hangouts.

Mine now does this weird thing where it opens random apps to the setting menu that has the option to force stop, disable and uninstall and keeps flashing and switching between them. I haven't unlocked the BL yet or done anything to the phone, I think its a software bug and hopefully google will release an update soon.
Edit: the random weird thing described above was caused by Greenify so I uninstalled it.

I'm having a lot of random reboots... anyone still with the problem?

I've had a couple more, I called Google today and made a trouble ticket to see if they are pushing out an updated build for us. I awaiting their response, but I'm certain they will fix this with an update.

Well it looks i got a lemon, its rebooting every 2 minutes, anyone knows google contact info for RMA?

Mine just started doing this. It happend twice the other day and I thought I did something, but just now while I was surfing the net on my computer with my Nexus 6 right beside me it rebooted for no reason.

Mine hasn't done it since I posted last. My Nexus 9 had the same bug so maybe its an app causing the system reboot.

I was just sitting on the couch 20 minutes ago, with both my Note 4 and N6 sitting next to me. I wasn't using either, but almost in unison, they both randomly restarted.

It's the aliens!

i get them a few times daily as well. usually it happens much quicker if i disable mpdecision, and use the ondemand governor. if i dont change anything, then i might make it through the day without a reboot. oh, and 99% of all my reboots happen when im using the browser. and the odd thing is, no last_kmsg gets produced.

I had two reboots an hour after I activated the phone on T-Mobile for no apparent reason. Went into network settings and changed from Global to LTE and the reboots never happened again

I changed mine from Global to LTE a week ago once I activated it yet mine has rebooted at least 3 times. I did notice that the last time was after I used wireless charging. I'm wondering if maybe the heat caused it to reboot.

Also happening to me (32gb blue, Bell Mobility Canada) ...has anyone tried factory resetting the device?

I also just picked one up from Bell (32GB Blue) today and had a random reboot while the phone was sitting on my desk idle. This was moments after tons of updates from the Play store. I read in some threads that doing a factory reset didn't work for most.
I also got a 15MB system update, on stock build LRX21O. Hope this isn't caused by hardware!
Edit: Just sent a text using "Textra", 2 mins later a random reboot occurred...

So I just had another one immediately after opening and closing the Messenger App (I stopped using hangouts) ... funny enough, same thing happened yesterday right after I closed the messenger app ... going to go back to hangouts as default and disable the messenger app to see if that helps

Was hoping the 5.0.1 update would fix this problem, but I'm still getting random reboots and shut downs, at least once a day.

my reboots are cured. the ondemand governor is broken in stock, and aosp, and has been the cause of the reboots. as soon as the developer of lean kernel fixed the ondemand, no more reboots using lean kernel

[Question] Nexus 6 randomly reboots, sometimes power button doesnt work

I am checking to see if other people see this on there Nexus 6.
I get random reboots, like once every 2-3days I would say. (Is this Memory Leak?)
Also sometimes I cannot unlock with power button, it will stay black screen. Here sometimes it reboots, sometimes if I wait 10-20secs it works again.
I am wondering whether to return it for another one.

Actually I never faced with my device. And currently my device's Up Time is about 180 hrs. Running last 7 days without any problem.

Go to this link and look near the bottom of the page. Paul, from Google, is reporting that 5.1 should "reduce unexpected reboots." Hope that means they have fixed it and they just used the word "reduce" instead of fix because of the fact that any phone might reboot given the right set of circumstances. Hopefully, persisting reboots will finally be fixed. If you read the entire thread (very long) you will see that many people have reported random reboots and they have experienced them under different circumstances. I'd like to know if they've found what is triggering the repeated reboots for everyone---only time will tell. Some have exchanged their phone for another and had success. Quite a few others have reported receiving 1, 2, or even 3 different replacements and still experiencing reboot problems. Don't know what the answer is. I'm just sitting back observing, waiting to see if it gets resolved before purchasing the N6. If I don't see a satisfactory resolution, then I probably won't get one, even though, before it was released, it sounded like the just the phone I wanted.
https://productforums.google.com/fo...c/nexus/other-discussions/nexus-6/9aVUBrwdUZU

I have the same problem on my T-Mobile Nexus 6. 2 reboots in the past 24 hours. It occurs randomly too. I just got the phone like 3 days ago so I'm hoping that 5.1 will fix this issue. Next to the reboots I haven't had any issues with the phone. It pretty badass actually. I switched from the Note 4.

Thanks for the feedback! I really like the phone no way I will get rid of it for this issue. Its just annoying as nexus 5 I didn't. Have any issue like this but I guess KitKat was a more stable than LP.
I will await 5.1 which sound imminent
