[Q] automatic random reboot

hey all,
i got my galaxy note now 3 weeks ands it's rebooting random all the time. at a service point i let them do a factory reset but that did not work. does anybody know a solution for this problem? because i dont like to send my note cause i will not have a few days sow if anyone got a solution i like to try it.
Gr Sven

Suffering from the same here
I think its related to one of the apps - I will start removing my installed apps one by one from tonight - Will keep you posted with the updates.
Also, if anyone out there had the same issue; please advice!

I had the same issue on previous android devices..I managed to get around it with numerous hard resets. Also I believe that a certain combination of apps will cause it too..but i don't know which ones. I've got a dell streak right now, and its been stable for a few months..having said that, it still randomly reboots once in a while but no where near the consistency it used to.

I had this problem too and it seems to be an installed app problem, particularly any that change the wireless settings in some way or apps that stall when accessing the external SD card at boot times.

this is exactly what happens to me guys, same problem.
Random reboot and this happens all around the clock, no matter if it is day or night or if the phone is in flight mode...
Frankly I don't want to uninstall my apps one by one to check what app is causing the issue because I have no time to spend on it...
I hope that someone with more software skills than me (I am just an user) will succeed to fix it...
cheers.

Do you have Dolphin browser installed?
If it's the case, don't search further...

What's the problem with dolphin browser? I constantly use it and never had a restart. Is OPs phone overclocked or undervolted?
Which rom and kernel are being used?

mine is also rebooting every once in a while for no apparant reason. Mostly when I unplug it from the USB cable but not always. This happened from the first day on. I never did a factory reset but considering it now since the SMemo app is not working anymore (no strokes are visible) and I am out of options.

Come to think of it, mine also reboots when disconnecting from USB storage mode. I thought maybe this was buy design? Maybe not!

why would you need to pay anything if the phone is under warranty ?

I also have this issue, I found out that its the power button..

Dolphin is a well known app for causing random reboot, since SGS 2.
Not for all users but for many:
http://forum.xda-developers.com/showthread.php?t=1321612&highlight=randomly
But without Dolphin installed, I really don't know...

I think it's the SD card causing these problems.
My reboot problems all disappeared when I removed the 32Gb sandisk card. I replaced it with a 16Gb card and was very careful about which apps I installed on it. Now whether it was the card size/brand or the selective apps that resolved the issue I can't be sure. Having Dolphin's cache on the phone memory instead of the SD card might also be a solution.
But it's worth investigating if you have reboot problems with external card installed.

Hi guys,
As soon as I got my Note, I rooted it and flashed a custom rom. Never had problems with reboots so far.
So, for a change I though setting it beck to stock was a good idea, with the upcomming ICS update.
As soon as I flashed the stock rom with odin, and it was back to factory situation, the reboots start happening. Every 3-6 hours the Note rebooted. Got in contact with Samsung (NL) and suggested to execute a factory reset, so I tried that a couple of times. But no luck, the reboots keep happening. I thought maybe it was an hardware issue. I have no Sdcard, only my SIMcard, which was a bit warn out, so I order a new SIM. But still, the reboots keep happening.
Then I decided to root my device again and flash a custom rom (Rocket-Rom), and guess what? No more reboots!!!
I hope this helped.

To me, I think automatic reboot is somehow still acceptable. I experienced two times auto power off. Both were happened after I charged it over night, unpluged the charger and left it without unlocking the screen, drove to my work place, and found it dead
I'm only having it for 2 weeks and I haven't rooted it.

it maybe a usb charging issue which is causing so much grief to many note owners. Mine has a defective usb port and it makes my note go crazy, including reboots and makes the note think its charging when its not even connected to charger at all.

Using note since dec... Faced such problem 5 or 7 time whn my phn was nt rooted... But nw its working fine... Using rocket rom v 20...

You just need to format your internal sd card and all should be fine, it's a fairly common issue

actually I had left it alone for an hour or so and it seems to have come back to life again..
although it has lost my security settings and all the haptic feedback has turned itself back on again
lost my swiftkey settings also it seems
piece of shizzle
EDIT: in fact it refuses to keep any security settings at all, no lock screen nothing.
lost all my texts everything, f*cking cr*p
walkman isnt working either
wondering why i bothered upgrading cant actually see any difference really other than a more colorful boot image. hoping that the battery life will improve as that is rubbish - I know it takes a while to settle.

No No No don't format anything. That would make you loose all data and apps. Let it be. It will fix itself. Could take between 5 minutes and 3 hours. It is not an error or a problem or anything. Its just getting ready.
But if you really really need it to boot, yes you can format internal.

I don't know why it screwed up your settings buddy maybe due to a small flashing error. Flash again and you will see the difference in the upgrade. Battery life is amazing. I can get two days if i switch off data, and 1.5 days with data always on. Plus multitasking is smoother and the camera has HDR, the Xperia Z's ClearAudio+ engine, notification toggles, a sexy new Album, blah blah. You'll find out.
Oh and you did the right thing by letting it be with the white triangle sign.

its an Xperia T I have in case that wasn't clear...
so I installed it from a zip in the end, rather than an ftf as flashtool was playing sillybuggers.
I should just go in to recovery and do so again? presumably along with the JB GApps
like I say it was working fine after the first time I did that, but when I turned it off this morning it went all manky
I would however like to keep some of my settings for the apps that havent already had their settings raped.. is titanium the best way to do that? or to move things to SD card and reinstall or something
also home button not functioning- at all
the no screen lock is a big issue as I have my work emails on there - if I lost my phone I would really get in trouble

Most the app stuff is on /data not /sdcard so you'll be fine, some of the data made by apps will be in /sdcard/android but there isn't much there as most is in /data/data so if you backup /sdcard/android you'll be fine, you may as well backup your whole sdcard and format, that's the solution I used and most people have been using. If in doubt use titanium backup to also backup your apps if you're unsure

I believe the best way is to use a ftf file with flashtool. I have not tried any zipped roms. They might be faulty. And Titanium Backup is the app to use to backup apps. Moving things to SD card is useless as they will be removed when you install a new rom. Always make sure you do a full wipe when you flash a new rom, and flash the kernel before flashing the rom.

[Q] Has anyone with an Xperia TX faced the Sleep of Death (SoD) problem?

Hi,
I bought an Xperia TX about three weeks ago. Since then the phone has gone into the sleep of death state four times! I've read all the discussions regarding the same problem in other phones such as Xperia T, V and Z, and applied suggested fixes such as turning the WiFi off when not using the phone. But, alas, none of the suggestions has prevented the problem. On the other hands, I should be happy because there are some people with Xperia V whose phone hangs four times a day!! I am very surprised because apparently this problem occurs for Sony Xperia models more often than for other brands. I hope the problem to be a software related one and to be solved by an update fix, though some Xperia T owners who have updated to JB still face different problems. Please let me know if you too own an Xperia TX and have faced this annoying problem.
Many Thanks

Actualy you are the second owner of tx to Face SOD dont expect much replays here

I am not sure if it is just your firmware because I am on. 197 and no problems. Most people are on. 197 as well so probably not many with that problem. You can try doing a reset through pc companion and that might fix it. It seems to work for various issues that have come up for others.

I had 3.212 when I bought the phone. The phone is being updated to JB right now and I wish the problem would be fixed by this update.

i got my TX a couple of day back and root/flash to FXP213 now. I have tried FXP208 to 213 and this SoD occur in all version of ROM.
i;m trying to get the log for the ROM guy to take a look. I've trie dth wifi off too but still SoD. I notice if i left the phone in sleep mode for over 2 or mayb3 hours, the phone will juz sleep to death.

Actually i have been getting SOD since a couple of weeks on my TX. It happened when the phone is charged overnight.
Another thing i noticed is that each time i reboot the phone after the SOD, it says my my SD card is unrecognized and if i want to format it.
I just took out the SD card for the time being thinking it was causing the SOD.3 days since i removed it and no SOD yet. Any ideas?

Hi,
One of the guesses about the causes of the SoD problem is in fact SD cards. However, there are reports about having the problem even after taking out the SD card.
Have you updated your firmware to JB? Since I updated mine 5 days ago, I haven't faced SoD (touching wood!).
So, I recommend you to upgrade youlr phone if you haven't done so.
By the way, I vaugely remember that those who complained about the SD card cusing this problem, recommended to use SD cards of classes 2 or 4 (and not higher classes).

using ICS 3.212 a month
never facing any SoD
using from 3.212 Russian ftf
and I'm using sdcard 32 GB class 10 without any problem
never hear any information, that higher sd card class give error or SoD to some phone, except for bad sd card. . .

I have been having a similar issue with my TL ever since I upgraded to Jelly Bean about a month ago. For the first two weeks everything worked great and I loved the new update, but now seemingly out of nowhere my phone is starting to act up. At seemingly random times my phone will either freeze or hang or just generally not respond, the navigation buttons disappear and holding down the power button will not let me shut the phone down. The first few times it happened a message would pop up telling me that some process or app is not responding and I have the option to either wait or force close it. Normally I just tap "Ok," and then a slew of messages pop up, basically every process and app crashes simultaneously, forcing me to restart by holding down Vol up and Power. When it powers back on everything works fine again, but sometimes it will do this as much as 4 times a day. It doesn't seem to matter what I am doing at the time or what apps I have open. Sometimes I will go to unlock my phone and it will be stuck on the lock screen (I can lock and unlock the phone fine but no navigation buttons are visible and I can't tap on anything). It seems like now it will just say "Xperia Home is not responding" and I am again forced to restart.
Not sure if this is what you mean by SOD, but it is quite frustrating seeing as everything worked flawlessly about two weeks post updating.
I am using the Xperia TL (LT30at) 4.1.2 build 9.1.F.1.120 Kernal version 3.4.0

Sorry for the late reply.
Yes am updated to JB and rooted.
Since i removed the class 10 SD card, No SODs....not even once.
Only thing is that sometimes, when unplugging the charger, the phone does not get the event right away and charging light stays on. After a couple of minutes it goes back to normal.
At least no SODs....

No, like I said I have never tried modding or rooting my phone. I am on stock JB firmware from whenever I updated my phone a few weeks ago. ICS never had any issues like this, JB never had any issues until two week into the update. I'm just confused as to what happens to make these issues occur, I mean, everything was working fine and then for no reason something is causing my apps to crash and my phone to freeze? Doesn't make sense to me...

Restarting

i would like to know if Ia m the only one, experiencing constant restarts on the phone,almost every single day and more than once.

hmm sounds like you have some sort of software issue, reflash the software and see if you get this issue again. I've had the phone 2 weeks now and had no weird restarts or anomalies, check my sig it shows what firmware on.

Your sig is what I have really surprised, o well might do a reflash or something, but the phone has also shut off a couple of times, not sure why, but when I unplug the phone from the charger usually.

Well I thought I was the only one, but it seems in android central people are reporting random shutdowns, please let me know if this is a widespread issue, because they also said they dont have an SD card to wipe, so it seems it's not the card causing the problem, but certaintly the same thing is happening to me.

I having these issues also, i have left a message on sony facebook page. This is starting to piss me off for a $1000 phone it is not good enough. It is also corrupting my files on the phone

Wow that is definitely not acceptable, Im leaning to switch back to the HTC One, but still debating, depends to see how many are having this issue.
if anybody knows let me know if this a known issue or if is affecting only a small portion of the phones thanks

HERE YOU GO MY FRND
All users who are facing this problem... i have solved it.. the prob is with android 4.0+ onwards... do not pop in mem cards from other fone directly...
take your memory card out and copy the entire card data on hard drive and then format the card in pc with default settings. then switchoff the fone and put the card in it... it will take smtime to initialize the card at first run. have patience and let it create the suitable folders... the data u looking forward to copy is pics, vids and music files... rest stuff is there on ur fone and it will stop rebooting. DO NOT FORMAT THE CARD FROM WITHIN THE FONE... it has been seen that with android 4.0+ they do not format flawlessly....enjoy and ur rebooting problem will b over...

I have the same problem. My Z1 restarts several times a day. 10 times just today.
I don't have a sd card in the phone, and I never had any sd card. So that can't be my problem.
I don't see any pattern in when it restarts. I can be browsing the web, checking facebook, playing games. Or when the phone just lays on the table. Charging or not charging.
One thing I have seen is that right before it restart the cell signal is gone and there is a sim card icon in the notification bar.
I'm switching cell provider in 2 days, so I will see if it gets any better with a new sim card.

well that doesnt seem a solution for me, I tried what he said and didnt fix my problem the shutdowns happen quite often, I might have to look at a stable device, I may look at the incoming nexus 5, I do like the Timescape UI, but restarting a couple of times a day I cannot agree to that, I had it happen when a call comes in, so it is a problem, because people think I hang up on them.

I got my new sim card and the phone haven't restarted once!
So it looks like my problem is solved.
The difference between my old and new provider is that my old (OneCall in Norway) is renting net from Telenor and the phone is roaming most of the time.
My new provider (Netcom) has its on cell phone net.
If you have the same problem you could try with a new sim card, or use the phone without a sim card for a day.

I've this problem too. I don't have an sd card in my phone and I didn't move any old files from another phone. I've been getting a random reboots per day in the last 3 days. I love this phone but I'm not sure if I need to return it. It is unacceptable.

[Q] my xperia x8 turns on and off again and again

Hello everyone.
I just got my xperia x8 from my brother because he didn't know how to fix it.
The phone seems like it has not even a scratch.
The issue is that everytime i turn it on it is just turning on and off and on and off again and again.
I don't even have time to input my pin.
The battery always seems to be drained although i charge it occasionally.
I have updated it's os with pc companion, but it keeps doing the same thing.
Is there anything that i can do to fix it?

try to flash stock frimware through flash tools(this wipes the data & reinstalls the system partition)
Normally flashing fixes all software fault but if your hardware is damaged so you shouldnt be hopeful.
I think its a sw problem but even an empty battery can cause exactly the same react.(put another battery then try flashtools)
Hope i could help you

that's our little greek secret... no modifications to the software but he kinda had troubles with this mobile for the whole period of time he owned it.he didn't receive messages in the particular device as far as i can remember. the battery doesn't seem to have anything wrong though.it is just sliiiightly puffed but nothing that alerting.i mean i havent charged it for a long time and it can still power the mobile's "neverending loop". if there was a problem wouldnt it not turn on at all or something? i don't have an extra battery and i'm thinking of getting through with the flash stock romafter i charge it a bit.. should i? and if yes, how? i've never done that (a guide would be great )
