Strange "black" Reboots

Hi!
I'm suffering from reboots on my Note (also on my S2...). I call them "black" reboots because the screen becomes black, there's no start-up animation , I only hear the sound, and the home screen don't comes up, or it do it after a long delay. So, the screen is mostly black. Until 2-3 minutes pass, and reboot again.
-Sometimes occurs simply starting up the phone in the morning. I'm advised of a slow launcher load (Go Launcher, but it can occurs on TW).
If I go to System Monitor (System Panel app), I see the 2 cores working hard, toghether or alternating. The "System" app goes mad. The battery drain becomes quick, and the phone back around the camera begins to warming...
After 2-3 minutes with this behaviour, the "black" reboot comes up. Often, after rebooting, the message "Unable to run System process"- Force Close-Wait (or so) appears in the black...etc
If I force shut-off, then I wait and then shut-on again, all things seem normal, until...reboot
-Factory reset (through Recovery, of course) seems arrange all things, until I load again the apps. I've unistalled all "tweaking" apps for overclocking, Ram managing, etc. I only have Root explorer and Speed Boost as Root operating things...
- My Rom is an odex Pre-rooted XXLC1, Modem XXLB2, but the multiCSC is not from it.
How the phone can become so unstable with only the half memory app capacity occuped? (800 Mb or so of 2GB)?
And how can it often occurs on updating apps from damned Google Play Store?
Is worth to flash another Rom (not ICS...), or re-flash same with its CSC included?
Sorry if I've been too long. In my searchs I only see things about bricks or another type of reboots.
Thanks for read me!

i get these once every two weeks or so.

I also get these type of reboots, I get them on RocketROM and on previous roms I've had installed the only way I've found to get out of them is to boot into recovery and wipe the caches. Before I was rooted I removed some of the apps I'd moved to the SD Card and that sometimes stopped the boot loop. I now only update apps one by one someone suggested it was to do with the amount of apps moved to the sd card and the multiple updating of them. I'm still not sure of the cause I know its the only flaw on my Note that I'm fed up with.

Im running stock ics rom straight from samsung only with root and getting the same behaviour as yourself. About 2 to 3 times a week...

Guys, i don't know if I'm going to cry of pain or to laugh of huge joy, after seeing this is almost ..."normal"
We have a beautiful 500€ plastic and metal block which is unable to perform the half of things it's supposed to do! And we don't know exactly why...
Sure I do wipes, but most of times this fixes nothing, and the reboot returns.
If I re-install with Titanium, I am very careful unsellecting into the batch which things can cause problems, installing only a few apps.
After some days, I go on installing manually some others.
The Play updates are critical, as I see... Why? How it's possible that this "beasts" with so much RAM and so much App Memory (2 GB on S2 and Note!) fail down handling its management, with their super 2 core CPU's?
It's too serious. How we can live with a 500€ phone rebooting bad 2 times a week?
Can you imagine that on your computer, forcing you to re-install OS and apps once or twice a week? It's crazy. Is Android going crazy?
Maybe Samsung don't like Root users? Have HTC same problem?
There's someone with a non rooted phone with same problem?

Are you guys running stock? Had custom rom installed or still have?

I have this Rom, based on strict stock, but rooted: http://forum.xda-developers.com/showpost.php?p=24690725&postcount=154
Mine is the XXLC1
No tweaks, no overclocking, no CWM...

I had the same problem when my GN was on rooted LC1. I disappeared after I made a factory reset and let my apps reinstall by Play Store.

Yes me too got out of this strange reboot by a factory reset today morning.
Something is messed up .....
Very difficult to find that something ...
better idea would be a factory reset .....

I think the problem is with the Stock Samsung Rom, it doesnt happen in CM9 Roms. I had this problems wen on ROcket rom, but vanished when on Asylum Rom.

go wild...

Yesss, very difficult. I'm not on advanced technical stuff, but my intuition says that is something deep inside the Rom, something that is related to CPU-Memory management.
By the way, do you have/had many apps (250+)? Have you made recently massive update and/or installing apps, or massive "App to SD" moves?

You are pushing me a little step more to the wild side of Android.... Here I'll go!
It seems to me that the Note is a strangely different phone of, say, S2. Some apparently "simple" apps that I carry on from 2 years ago don't run right.
And the little lags that sometimes appear on touching icons, never, never appear on the fast S2.

Lol be carefully factory on ICS resetting...
Try and official rom, haven't seen it myself

Don't worry, baz77, I don't touch ICS by now even with gloves & calipers...

Warning with french ICS update

The ICS update finally appeared in France for stock Note.
It appears the update was pulled shortly after because a lot of users bricked their Notes in the process.
Moral of the story: don't update as soon as you see an update, but wait...
Samsung really sucks at software development.

as tu une source s'il te plait merci

Samsung france facebook page for the source.
SFR update and XEF for the short time i spent there.
i'm in the same case except that i'm booted and running( for me was a FOTA update, wich installed nicely except with a "failed " message after the fist boot), but the phone cannot be mounted by any ways under windows now ( even with drivers reinstalled ).
But some seems to be blocked in bootloop
Epic fail on this one, especially just before a week-end.

I'm one of the lucky few that got it to boot - sigh come on Samsung!

Managed to upgrade to ICS with 'failed to upgrade firmware' warning.
Missing S Note application, not sure whatelse it might be missing.
You can manually install S Note app by looking up apk file.
Search 'S Note app xda' from google if anyone having similar problem.
Kies 2.0 is recognizing phone as well. I can link screenshot if anyone need for w/e reason if it may help them.
Also, battery drainage problem still there i believe.
Tried the infamous aeroplane mode method, not so sure if it helped:
1. Turn off touch sound and screen lock sound from setting->setting
2. Turn on aeroplane mode
3. Switch off phone
4. Take out battery for 10sec
5. Boot and wait till everything loads
6. Turn off aeroplane mode
App called 'Play Movies' was installed along with ICS, but it gives 404 connection error for 'movie rental' section.
Other than that, Note is running really smooth with ICS.
Firmware version shows up as PDA:LQ3 / PHONE:LPT / CSC:LP1 (XEF)

Wasted time trying to download this so-called update

When I see that, I'm happy to install safe custom roms...
It's a shame for such a company to provide such crappy roms...

Well I am one of those who got stuck on the infamous Samsung logo...
Stock Note, purchased in November, never rooted, 2 GB updates via OTA since November, CSC XEF.
Yesterday morning I got the upgrade notice, did it OTA and on rebooting stuck on Samsung screen...
As an idiot I had been waiting for the "official" ICS ROM.
Thanks Samsung, lesson learned.

Many phone manufacturers will tell you to stay away from custom roms to avoid bricking your phone but to brick your device when updating on an OFFICIAL stock rom after receiving a notification is definitely UNBELIEVABLE !!!!! What is Samsung doing to this expensive device - after the EMMC Bug episode where many people have bricked their Note, now we have another update problem!
Samsung's reputation will take a hard punch with these things if the press writes about this. I think most people who bricked their Note will be fed up and avoid Samsung's phones in the futur.....

totally agree... it would have been good for them if they silently provide fix for the emmc bug... staying on GB has become the best solution to all this crap..

I have to say that I'm glad to hear of this. At least it's not just me!!!
My French note got the update yesterday and although it's not hung up or bricked, it certainly has huge issues. Running so hot and battery discharging even when connected to PC by usb. Using wall charger is barely keeping up with the drain even when not using phone.
Have done battery pull and cache wipe twice. No change. Factory reset, nothing either.
Swype not working. Premium suite totally missing. Really disappointing.
Probably not worth waiting for them to figure it out. Downloading UK version now.

I left my note on overnight under the following condition.
Wifi off
Bluetooth off
Data off
Auto rotation off
Gps off
Silent mode on
Power saving off
Between 1am and 10am battery % changed from 81% to 79%.
Quite satisfied with standby drainage.
I just did aeroplane methid as i mentioned on page 1.
Not using any battery save apps.
However when using apps such as dolphin browser, s note, s memo, there seem to be heavy battery drainage issue.
Charged fully then used the browser for approx. 30min and it was on 90%.

Does it say "warning;camera failed" ? And are you loading the camera from the lock screen or home screen?

I had the same problem with my new Galaxy S4 that I bought on 8 of may in 2013.
In the beginning, the camera work fine, but after several minutes, on each time that I tried to open the camera aplication it had black screen with an error message.
I tried to exit the battery and return it, it didn't help.
I tried to rebot to manufacturer settings, at the first couple of minutes the camera work fine, but later the black screen appear again at each time I open the camera application.
Here is a link to youtube that show the same problem that I had :
Search on youtube "samsung galaxy s4 camera fail"
What can I do ?

I am having the same problem with my s4; tried system update, factory reset... maybe i need to try to flash my firmware. so disappointed with Samsung. a flagship phone shouldn't have this problem!
to be safe, getting it exchanged... i never bought insurance before but it looks like i might need to if i am sticking with the s4.

It's a known problem. Loads of people have it. You'll just have to wait for Samsung to fix it.

From today speaking to a guy who repairs samsungs this is a hardware issue. Reboots and factory resets seem to fix the issue but the root of the problem is the the camera module either not correctly attached/or soldered to the connection so when rebooting or resetting the phone the movement of the device in your hand or laying the phone face up briefly re-connects the module to the device. I'm awaiting my new device as my carrier told me a few people have had this issue also.
Hope that helps

no it dosent.. it just crashes.. with a black screen!

I have taken several pictures with my 2 days old GS4 but in one occasion when I opened the camera and switched from the front camera to the main, the phone froze and reboot it self :/
I hope i only was a one time failure and not hardware or software relate.
Cheers

There are several other topics created for this issue Slow or reboot when opening camera apps and [Q] Galaxy S4 - reboot launching camera from lockscreen
So far, temporary fixes are limiting the background processes to 4 from the developer options in the settings menu and disabling air view options and smart screen options. This has worked for me, I haven't experienced any other reboots but the lag is still present and sometimes when enabling both cameras feature the app would freeze.
I'm not sure whether this is a hardware or a software issue but nevertheless most GS4s experience lag with the camera app, especially those on the octa version, the GT-I9500. I bought the phone internationally, not using a carrier and switching mine will be a pain; therefore i really hope it's a solvable software issue.

This happened to me yesterday. I tried factory resets, going back to stock with Kies, clearing data, but nothing works. I thought it was because of something
I flashed yesterday, but that wasnt it. Sad it happened so quickly and hopefully it can be fixed.

He doesn't work for Samsung he just repairs them independently so he is speaking from experience. But I have since asked another independent business and the toldme the same. My problem has now stopped buti believe could be fixed due to my new case on the phone pushing the camera module slightly in place? Who knows but I am replacing incase it happens again (really don't wanna be lumbered with an s4 with a broken camera)

Were you receiving any warning messages?. As I dug into this problem I've found there are 2 error types. In the 1st scenario the camera would crash and a message would be displayed. The 2nd one, would just turn the screen black after accessing the camera app and after a few seconds the phone would reboot.
If a message is displayed then it's most likely a hardware issue. If the phone restarts without warnings then disabling air gesture options and smart screen options along with disabling a few samsung apps temporary solved the matter, therefore being a software misbehave. It's not a permanent solution but until sammy releases a patch this could be a small fix.

Yup, I have that exact thing. Unfortunately, T-Mobile US doesn't have the S4 as part of their replacement "plan" yet. I'll have to check back later.

[Q] Please help :( i9505 Constant random reboot issues..

Hey guys..
I've owned all the Samsung Galaxy phones from the S+ right up to the S4 and I've flashed firmwares over all of them with generally no problems at all.
But lately I have a constant issue that has been plaguing my Galaxy S 4 (i9505) phone since I flashed the 4.3 i9505G (GE Edition) ROM over my phone.. (have since moved to OMEGA v12)
The phone just randomly reboots whenever it seems to feel like it.
It could be whilst taking a picture, it could be whilst using google maps, it could be whilst installing an app from the app store or just scrolling across the screen. It's basically rebooted through anything and everything and I've tried pinning it down to something but every time I think that I've got it sorted out. It crashes again whilst doing something else.
1 thing however has got me stumped. The phone has NEVER crashed whilst plugged in. If I keep the phone plugged in, it's never ever just rebooted on its own for me. Which got me thinking that it could be a faulty battery or some sort of voltage issue.
Coming from the 4.3 GE Edition ROM there are other people experiencing random reboots. But now I've just flashed over OMEGA v12 and right after flashing (I did a full wipe of course first) the phone rebooted whilst typing in my Wifi access key. After the reboot I was able to set my phone up and I did a reboot myself, then I went to the app store to add an account and the phone crashed AGAIN.
I'm totally over this issue with my phone. I paid a small fortune for it and I cannot rely on it at all. So I absolutely need it to work. I've had issues on 4.3 GE getting Mobile Data to work. I've had issues with it crashing and I'm just done with all of this.
Do you think that my phone is already broken? (It's barely 3 months old) Do I need to get it replaced under warranty? Can I even get it replaced under warranty, is there a way to even get my warranty back or reset the flash counter etc?
I'm just so confused guys I thought maybe it was my battery, and that my battery was faulty because I had battery percentages dropping and jumping around like mad. For example 15% battery left would actually have the phone turn off... and reboot at 0%. Then the light wouldn't go green for 'Fully charged' and the phone would sit on 99% or 100% but still not say 'charged'. In addition I could swear I had lost more than 10% of my charge in the blink of an eye etc.
I just bought 2 new batteries but they will take a week to get here.. and if the phone is still rebooting (and it isn't a voltage/cut out issue with the battery) then should I assume it's a hardware issue and that the phone needs replacing? Or could it just be a bad flash or something? The phone has at least a 2 year warranty. I don't want to replace it after just 3 months when I haven't even so much as dropped it once.
My recovery is PhilZ 5 Touch 6.0.4.0
I always check MD5 sums before flashing and do a full wipe:
- Wipe Data/Factory Reset
- Clean to Install a New ROM
- Yes
- Then Flash the new .zip file etc.
What on earth could be wrong with my phone?
I'll happily provide any more information, as I honestly cannot handle this happening and I have no idea what my problem is...
Thanks incredibly much for any help at all, what-so-ever.

I can only give you advice on some of the smaller issues that you mentioned. I haven't had a problem with reboots at all (i've flashed all manners of ROMs too, including the GE), so I'm guessing it is hardware related. You should get it replaced (if it still is messing up with the new batteries).
As for warranty, yes you can claim it back on warranty. To be doubly safe, restore it to stock: http://forum.xda-developers.com/showthread.php?t=2265477
Use Triangle Away: http://forum.xda-developers.com/showthread.php?t=1494114

Thanks a lot buddy I am in the EU definitely and the phone is purchased from the EU. I am actually about to flash it right back to stock now to see if it stops the rebooting issue. I will just have to live without custom roms for awhile and such. If it still keeps crashing I will wait for the new batteries. If it still keeps crashing again after I get those. I guess all that is left to do is render myself without a phone for a week or two and have it repaired...

I wouldn't worry mate it sounds to me like a definite battery issue

Hi leijonasisu,
I've stumbled across your post after having experienced more or less the same issues as you. After trying many custom ROMs in the last few weeks, the phone has barely been useable for more than a few minutes until it randomly reboots. At which time, I must start over with the whole flashing process. My question is, did getting a new battery resolve your issue? Or did you just trade the device back in?
many thanks

I can only give you advice on some of the smaller issues that you mentioned. I haven't had a problem with reboots at all (i've flashed all manners of ROMs too, including the GE), so I'm guessing it is hardware related. You should get it replaced (if it still is messing up with the new batteries).
As for warranty, yes you can claim it back on warranty. To be doubly safe, restore it to stock: http://forum.xda-developers.com/showthread.php?t=2265477

Looks like it's better to restore to Samsung stock firmware first then start again from there,
But this will upgrade the the Knox bootloader also.
Stock firmware can be downloaded here, www.sammobile.com/firmwares

I fixed this ages ago. It was a battery issue, I'd bit my bottom dollar that it would be a battery issue for anyone else too, I've read a lot of stuff online about people who have gotten bad batteries with theirs. Swapped to 2 third-party and apparently larger batteries and never had an issue and never looked back.
Sorry for not replying back much sooner but I forgot about the thread.
Try another battery and if within a day or two you get no reboots then toss the bad battery and enjoy your phone! The thing is the battery (due to voltage issues) can make it look like it's the OSes fault when in actual fact it's just a faulty battery and voltage issues.

same problem here.. s4 randomly reboot..

I got the same problem.
The phone reboots every few minutes on me when i want to take it out of standby.
Sometimes it works for a few hours and sometimes it just reboots itself every few minutes or it reboots when i want to do something.
So ur all saying that a new battery could solve my problems ??

Hi, the OLD problem WAS caused by the faulty batteries batch (easy to recognize - the battery serial no was beginning with BD code).
Now, more frequently it is resulting from KNOX related issues.

Only one option then: read the ROM-specific threads, loo for feedback posts. If ROM would cause random reboots, you can be certain that it will be written there.

Same issue with gt i9505, random reboot, earlier i had gt i9500 that was flawless with all rom n root n with everything, but i bought gt i9505 and its random reboot like in every 30 to 20 mints, im totally pissed n disappointed ? plzz help....

i9505 S4 sussed out the randomsoft rebooting
i9505 Kitkat random rebooting with UGNG8
UK - BTU
2014 November
I9505XXUGNG8
I9505YXYGNH2
I9505XXUGNG8
4.4.2
For me kitkat UGNG8 with random soft rebooting, tried everything with that firmware I could, reset to default and it was still randomly rebooting when ever it liked. Usually after swiping the screen out of wake lock most of the time. I even re-odin GNG8 3 times.
Cured by Odin with this one, below, which I thought I couldn't, because of the backward compatibility of the dates, but it went in ok. No reboots for weeks. Cured my i9505 S4
2014 July UK - BTU

So if you pulling you`re hair out with the S4, or trying to get rid, Odin this firmware first.

Interesting will have to give this a go, also the battery option.
For months I was running on Lollipop custom ROM, the developer did an upgrade and then the SIM card removed error started. I went back to the old version was keep getting the SIM Card removed error. A few days ago went back to Original ROM for NZ 4.4.2 and I still get the SIM Card error and now the phone just reboots randomly.

Do we think Google will fix this lollipop issue?

Hi all
Like the title says, do we think Google will release a fix for the laggy performance on the nexus 7. My wife's nexus got the update a few weeks ago and since then it's been almost unusable. She is not rooted and we don't want to go down that road
My Nexus 7 2013 has not got the update yet so I'm hoping they are working on fixes.
Any thoughts?

I noticed the same. But even before the update my N7 was having performance issues. Things got better after a Reset. But then I decided to try the Encryption feature and that is when I got stuck. Now it has been 15 hours and the device is still stuck on the startup screen. I don't think encryption takes so long....

having no problems with lollipop on my nexus 7 at all. enjoying it.

Are u using more then one account on it? (I think that switching between 2 accounts affect performance)

Done a factory reset.. Seems better

I turned on Develop Options then scrolled to the bottom and checked off "Kill all activities when you leave them" and I really don't have the lag anymore.

I as well am experiencing major lag with 5.0 on my 2012 nexus 7. I flashed the image when it was avaliable so a fresh start. I'm not rooted and also tried clearing cache via the recovery menu. I really hope there is a fix in sight or I'll be going back to KK or custom rom like cyanogenmod.

I had not previously tried that because I was not sure if the system is meant to run continually with that option enabled. It's more for testing I thought. However I did enable this option and rebooted. The result was an increase in performance but I think it only acts as a band-aid. We (users) should not be forced to take such measures after installing a fresh image or updating to the latest and greatest from android. I still hope there will be patch to resolve whatever issue seems to be causing the lag.
On a side note after disabling the Dev option and rebooting I'm noticing better performance. Not sure if this is a fluke or what but I thought it was with mentioning.
Thank you.

Something has happened. They've pulled the OTA. I've got 2 N7 2012s. One has been updated and is useless despite any cache cleanup and factory reset. The other is still running 4.4.4 and does no longer offer the lollipop upgrade to brick status.

I cleared cache and did the 'Kill all activities...' without any success. I don't want to wipe the device because my wife uses it and it is setuped the way she wants it... but is unusable right now. Will wait for 5.0.1 if that doesn't do the trick will restore 4.4.4

I have hesitated updating my kids N7's for the time being but you really should try going into Developer options and do two things.
Change Transition animations to 0.5
AND
Kill all activities when you leave them(that might not be the exact wording but you can't miss it)
My tablet is very useful at this point but knowing Google is pushing 5.01 to other Nexus devices I will hold off for my kids tablets.

I've tried every tip I've come across including cache wipe, factory reset, developer options and stripping the system from everything that isn't strictly necessary. None of this makes noticeable difference. I've even seen people suggest hardware failure, but I find it hard to believe that a tablet that has shown no symptoms at all in the past should break the minute it is upgraded.
