[Q] Random shut down - Diagnostics?

I have had the Galaxy Note for a month now and I have had 4 times randomly where it seems to have shut down. When I press the power button nothing happens, I have to take out the battery for it to get it started. I suspect maybe an app is the cause, are there any diagnostics programs for android phones that can log so you can see what causes the crash?

You are in Stock ROM or Custom ROM??

ROM version

Latest stock ROM, 2.3.6 XXKL7 kernel 2.6.35.7, since ICS is on it's way I thought to wait with using a Custom Rom.

Are you rooted? Custom Kernel maybe?
Also, no need to pull the battery, simply long press the power button for about 10 seconds and the phone will restart.

Haven't changed anything yet, so no Root. I tried the 10seconds every time it happend but it doesn't work seems like it has crashed and only removing the battery will do the trick.

I had rather similar problem with my G. Note after about 1 month.
Problem seem to come from Android System failure and cannot read
the Ext SD card after some of the apps had been transferred to the
Ext SD. I am not quite sure why it behaved like that.
The phone just hanged and will not respond. I could power down by
pressing the power button. Then I would press power button for more
than 10 sec it will boot but after a short while will still hang. I would
then remove the Ext SD and try to re-boot and this time it will work
but those programs transferred to the Ext SD are no longer available.
Problem appeared to be due to the inability of Android reading the the
program(s) in the Ext SD. Uninstalling the programs seem to work.
The data in the Ext SD did not interfere with the working of the phone.
Deleting the program files in the hidden .android folder seem to do the
trick.
Can any of the Gurus or expect please advice on this and why it is behaving
like this? Is there a a diagnostic program that can assist in identifying the
problem? Will appreciate any assistance. Thank you.

Today my phone has shut down twice and I missed some important calls. I adore this phone but I have to ckeck constantly whether it is on or off. It is not really off, when I charge it I hear the connection sound. So it must be on but in a state of coma. OP can you see if we have the same problem? I am on stock and rooted, but I've been having this issue prior rooting. Pressing the power button for 15 or so seconds restarts the phone. Surely it is an app, but which one?

I have a similar problem.
Running RocketROM R17 + CFRoot Kernel.
Some days it is fine, other days it can just hang twice a day, and I only notice it when I try to wake the GNote up.
Have no idea how to even start debugging it.

am using note since 2 months and i haven't faced such problem. and am suspecting this issue may be with some of the app or apps not responding properly. take all backup and try resetting your G note.

Exactly the same thing happened to me like the OP, twice since I bought my phone. I am running stock & no SD card.

HELP ! My Galaxy S4 keep restarting !!!

I bought S4 2 months ago. Recently, it keep restarting and restarting. The battery go down from 50% to 0% when it restart. Anyone know how to fix this issue ?

Same thing over here
My S4 acted that way also.
It happened when I took burst pictures and then touch the little photo icon in the corner to see the captured images.
The phone restarted at 0% battery and got into restart loop.
Only removing the battery for a few seconds could stop this loop.
Now, I reinstalled a new ROM.
Hope it works.

Try install new recovery+ROM

There are many ways to try to fix this issue start from the least expensive :
- disconnect wireless
- remove sd card
- remove the battery and the sim card and reinsert them
- check if your battery is swollen and replace it if so
- try a factory reset
- if you have a custom rom try stock rom
good luck

- i already removed sd card, but it keep restarting.
- Just did, didnt work.
- My battery is fine, lots of people are suffering this problem so i think this is software, firmware, etc. problem.
- already did, twice.
- I havent touched anything about ROM.

Those are diagnostic tools, they log every thing including fatal errors that cause the system to restart.

Getting the same-ish problems. Phone is rebooting like mad, doesn't matter what ROM I have installed at all. Not sure if it's an issue with my battery but it seems that it could be a voltage/current issue that causes the phone to die for just long enough. As everyone knows if you pull the battery out whilst the phone is on, then put it back in after a second or two, the phone tries to reboot without you ever having pressed the power button
I just got 2 new batteries. Gotta wait about a week for them to come. Gonna do some testing, see if it stops the issues. If not, then it's a hardware issue and I'm gonna see if I can get it replaced under warranty.

How to use logcat
My problem seems to be different compared to the others in this thread, but don't want to start a new thread. Currently my S4 is lying in the office all week, because I use another phone, when I am outside of the office. It's equiped with pre-rooted MGA, but I also tried various other ROM's, with different ways of flashing e.g. CWM, Odin etc. also no wipe/full wipe. The problem is that as soon, as I take the phone away from the office, I have several restarts a day, which is never happen in the office. This is strange!
My thoughts are, that some app is responsible.
questions:
- can I find out in using logcat? / How to use logcat?
- There is a description to boot the phone into safe mode http://skp.samsungcsportal.com/integrated/popup/FaqDetailPopup3.jsp?cdsite=my&seq=871239. It's not working for me. Has anybody tried that?
- Any other ideas?

Try to swap batteries. When phone keep restarting all the time battery is faulty. Hope it helps.

Hi guys, I tested a few days before coming back. So what I can say now

I believe that goes in the right direction, but turning off GPS did not help. But I think it must have to do with location, sometimes it is stable the whole day (same as in the office) sometimes 2-3 reboots, one after the other.
Must be an app, but how to find?

Phone freezing on me

Strange problem. My phone freezes on me every 35-40 hours of power on. I need to remove battery and restart the phone for it to work. I could be just be in the app drawer or playing a graphic intensive game the phone would just freeze.
I don't know why this would happen to an otherwise wonderful phone. Snappy fast and great battery otherwise.
I've done the official Sammy firmware upgrade OTA and the phone is stock unrooted
Any clues?

Use Helium, It's an app by Clockwork Mod, It does the same as Titanium backup but doesn't require root

I'm having the same problem it will freeze home button or power button doesn't have to take battery out its a bit annoying!

Try to use without ext sd card if there is any & observe.

Hey guys, I just wanted to share my experience with my SM-N9005 that's a week old today.
When I first unboxed it, it slipped in my sim card and 64GB sdcard and turned the phone on.
During the second or third screen of the wizard, the phone froze and rebooted.
After that, I went through the wizard again with no problems and finally to the homescreen.
I noticed on the status bar that the Play Store is failing to install / recover a whole host of apps and during that, I received that "Prevention Information" nonsense, the phone froze and rebooted after I tapped to see if I can find this app but all it showed me one was app, which was the Play Store services. I assume, maybe the apps failed because the services and Play Store wanted to update.
Well after all of that, there are times when the "Prevention Information" comes up, the phone won't freeze and soft restart (Just show the Samsung logo and come back to the homescreen with one or two vibrations) right away but eventually. There have been instances, where for example, I would be in the BBM for Android app or WhatsApp when this happens and return with no chat history but that happened once or twice, I think there was another instance that I lost information but that might not necesserily be an emmc issue but due to a sudden reboot or freeze without being able to save properly.
I also get a notification toast that I am running low on memory when I have plenty of memory left. (I would start seeing this around and after 10GBs have been used)
Things I have tried:
Factory Reset from the menu option.
Factory Reset from Recovery.
PC ODIN to the very first .tar ROM with corresponding CSC (XME) for my handset.
Removed the sdcard to see if it was that.
Nothing worked but the problems aren't as frequent.
I can't play games for too long because it will soft reboot. The phone does get warm quickly, which is a concern.
I think that's about it, I do love the phone but if this continues and this is a Samsung bug, I might just hold off from sending it back and buy a Nexus 5.
Samsung has been having too many issues with their handsets like faulty emmc chips, sudden bricked phones, multi-touch screen issues, etc.
This will be my last Samsung device either way but I am hoping that there's a fix because if I send it back, that's that.

I'm thinking of returning mine and sticking with the s4 to much hassle I've factory reset my device and left out my 64gb we card and see where it goes from here.

[Q] Sudden Device Lag

I'm having this problem with my white N9005 device, it's making this annoying lags/hangs whenever im using it. It's like something is updating on the background. It will hang for 2-3secs then go back to what it's doing.
For example, messaging, whenever im typing something it will stop but i can still press the letter but won't show up in the screen, after said lag the letter that i pressed during the lag time will appear as typed. I dont know how to explain any further. Anyone experienced this issue? Any solution? Thanks!

Check for rogue apps that could be slowing you down or next I would back up any needed info from your external SD card then format it.

@jdgamble i'm having the same on my exynos note 3 after upgrading to kitkat! i'm still experiencing the problem! please let me know if you find any solution.
edited: the problem got sorted out after removing the external sd card! there isn't any virus on it but the lag is no more! even the boot & shutdown times are much faster!

Galaxy S5 Randomly Corrupted

Monday morning my device working great. Then randomly my finger print scanner stopped working. I also noticed my SD card is no longer working, says it's corrupted and asking to format. I now have to access my phone via a pattern and for some reason it is VERY slow to show the screen after pressing the power/home buttons. I cannot install any applications, and alerts me my device is running out of storage even though there is 500MB+ remaining. It's now also very slow in response.
I tried checking the finger print scanner settings but alerts me that and error has occurred and to restart the device. - doesn't work..
I've had my device for two years and never has an issues.
Device is rooted but still has stock.
Model: SM-G900P
Kernal: 3.4.0-9634333
Android Version: 4.4.2
Software Version: G900PVPU1ANCB
I also want to mention that I got a text message the other day saying that I'm eligible for an upgrade from Sprint... Day later phone starts acting up. I'm sure restoring the phone or installing a custom rom might fix this, but I'm wondering what would cause this.
Thanks

Try booting into recovery and clearing the caches, often cures random problems like that

500Mb is not a lot... I would back up your SD contents, format it like its asking, then put your backup back on it, low space would certainly explain the lag and what not, not too sure about the fingerprint scanner though.

Thanks for the response. Unfortunately that didn't work.
Perhaps it is some sort of virus or malicious attack on my device?

Didn't install anything. Really just use my phone for text, email, and calling. It's really bizarre. I think I'll just have to back up and restore or get a rom.

Did you try my above suggestion? If you're open to it then yes, I would factory reset.
