[Q] Phone randomly restarting? - Galaxy S I9000 Q&A, Help & Troubleshooting

Hey, a few days ago I started my first serious issue with my phone (I don't consider the lag or gps problems serious).
While being in cell standby (and I don't use it), the phone has restarted completely randomly 4 or 5 days in a row now. I have no idea what's causing it. I'm prompted to enter my sim card pin again upon reboot.
Has anyone else had similar problems? Are there any ways to fix this? :|
I'm using the official firmware available (I haven't flashed), XXJF3, and the phone is not rooted.

uninstall whatever is causing it
do you remember what have you installed recently?
just uninstall the latest Apps that you installed in the last few days

I have the same problem, only in my case it happens once every 2 weeks...
Because it happens so infrequently I haven't done more research on this issue. My idea was to try to determine what is going by going over Android logfiles, but that is from my assumption: everything is logged under Linux. Not sure if this is the case for Android.
Anybody any suggestions on which logfiles to read/examine?

how to fix turning off issue for samsung i9000 ?

I just have updated my mobile from 2.2.1 to 2.3.4, i used this forum tutorial - http://forum.xda-developers.com/showthread.php?t=1139050
I have issue - my phone is turning off for no reason, you know i don't have lots of apps only fb,twitter,skype and 'advanced task killer'
actually when I am doing Skype video calls, writing SMS or anything else my phone just changed to 'black screen' every couple hours and afterwards my Samsung turning off with sound. To turn on I need take battery off and then into back then he allow to turn on...
before I updated I had little bit similar situation, my phone had 2.2.1 version and i didn't have black screen, but my phone just had 'freezing' for 10 sec or more...
what's problem for? what's your suggestions ? thank you a lot.

I have this issue as well, although it doesn't happen as much since I upgraded to gingerbread. I did have it happen once the other day. I was listening to music and I needed to make a call and when exiting the music app, it froze. It then went black and I had to take battery out and put it back in. It's annoying if you got a otterbox case on it with two layers. I had heard updating to gingerbread stops this but so far I don't think it's 100%. I use my phone as my alarm and one time it went dead with a full charge and I was almost late for work.
Let me know if you figure something out.
what can say experts about our issue ?
I will take some day my mobile to repair centre.. it's sad if couple of people have same issue and nobody can tell us the problem reason.
Try to flash a custom kernel and see if it the problem is still there
can you tell me or give information what's is 'flash custom kernel' ?
I have also encountered this problem, very frequently if i may add.
the problem actually first occured a few months ago, after i updated my firmware to gingerbread.
In my case the phone does not freeze, the screen wont turn on or respond to any gestures (hardware/capacitive button won't too), however any running process still runs, in specific i can still recieve phone calls, or at least hear the ringer.
I know of many other people that encountered this problem, all came from different ROMs (MIUI, SH 3.5 and up, Stock, PilotX etc..) and i, for one, can say that in the past two-three weeks it atarted appearing a few times a day.
So - does anyone have any ideas for the nature of this BUG??
BTW I use the i9000t which i own for over 7 months now.
Same problem
Hi, I have the same problem here.
and have seen this myself on stock roms too.
It doesn't happen very often (only once on my phone for now) but it is getting me pissed off as no one knows the nature of this BUG.
could it be a problem with the latest 2.3.4 version ? or an update of one of the applications?
I don't have too many apps on my phone only skype and 2-3 games.
the only thing I can think of right now is that all people who had this bug had skype on the phone but I don't really think it's from that.
Hi, And-roid if u ll update to 2.3.4 your mobile will working deffo better, i suggest you update your mobile to 2.3.4
Hey eddys, i have 2.3.4 for over two months now, and the problem just go worst...
Hi eddys,
I have the 2.3.4 (and my brother and sister in law have it too with a stock rom).
this is happening on all roms and all kernels...maybe a problem with the 2.3.4?
I don't know but it is very weird, no one has an answer for this....
edit:
just checked this with my phone supplier and of course they have no idea what so ever about this bug.
come to think of it they didn't even know how to fix my brother in laws "problem" when the 3G internet didn't work (settings-->wireless and network-->mobile network--> check the V on Use packet data ) so no surprise there.
Anyone???
Maybe theres another forum that this problem should be posted at??
I have this bug too, but only while tethering. I've found a solution to the tethering related crashes - after you start tethering, go to the SuperUser settings, and disable root permissions for android wifi tether. Your phone shouldn't crash anymore.
hey zyczu,
unfortunately, I do not use tethering at all, do you suggest i should disable ALL root permissions?
This bug is really getting on my nerves!!!
Everything else, but this, is working great...
Since upgrading my i9000m to 2.3.3 through Kies, my phone has exhibited similar symptoms 3 times: freezing, not responding to touch etc.
The first time I had pulled the battery when it did this, but the 2nd time I had just put the phone down a minute or 2 earlier so display was off so didn't notice it(about 2 weeks ago). And the 3rd time(today), I was using it at the time, and so started taking off my rubberized case, only to have it restart before I got the chance to pull the phone back off.
Startup took much much longer than normal, which I recall the startup was similar during the 2nd "freeze & reboot". For some reason today, I randomly though maybe its an OTA update so I checked "Settings..About Phone" and found my kernel version listed as:
Code:
2.6.35.7-I9000UGKG3
[email protected]#2
I have no idea what it was before, but September 8th was 2 days ago... It is possible it said that before today's restart but no idea. I have a PIN on my SIM so when starting up have to enter PIN for it to work, but on these auto restarts I never got asked for my PIN so it could have restarted other times too without me noticing(ie. middle of night).
Hmm, mine used to something similar when I would leave Bluetooth on but would move out of range of a paired device. After a few minutes it would just shut down or stop responding. Haven't had that issue since moving to Milkys rom.
hi guys, i just used this tutorial http://androidadvices.com/how-to-up...0-to-stable-gingerbread-xwjvh-2-3-3-firmware/
first I installed 2.3.3 XWJVB then 2.3.3 XWJVH
just doing step by step...
my phone was working fine 2days then i had same issue and then I changed to original SAMSUNG battery and it's working perfect.
try this..
p.s. what kind of batteries you have 'original' or 'non-original' ? thank you
madmigs:
I did not notice the kernel version ive had before, however i took my phone to a service center today, and for what i can see i have the same version as you do, take aside the i9000t instead of i9000m...
eddys:
Ive been using different batteries orig/non-orig on and off, although since ive noticed it hurts performance i stopped doing that, do you suggest that this might be the cause of the problem?
If so, the factory wipe i just did (formatted the internal SD card) should do the trick.
try reading this it helped me since i turn the wi fi off when i go out
http://androidforums.com/samsung-galaxy-ace/312084-randomly-turning-off.html
Are you guys experiencing turn-off issue while phone is in the locked state. I mean you locked the screen and then after a while when you picked it up for unlocking it was powered off. If anyone has this issue, then I found a solution. Just let me know
my turning off issue went back and it's getting every time more annoying, I don't know what to do...

[Q] S5 mini 4.4.2 full stock random freeze/reboots

Hi, i'm trying to find out what is the problem with my friend her samsung s5 mini, (running android 4.4.2, full stock unrooted).
Almost every day her phone freezes for no reaseon and needs battery to be pulled or it simply random reboots while she sleeps and then her alarm doesn't go off in the morning as the phone is waiting for her pin number after restarting (she says turning of the pin is not an option).
Is there someone who found a solution for this or what might cause the problem? i told her to install an app to auto clear background apps and also suggested to take out micro sd card for testing but the problem remained.
Also factory reset didn't solve the problem

This seems to be a common error with the S5 mini. There is a whole thread in the German Android forum about this issue. Also the German Amazon product page for the S5 mini has about 40 users complaining about this problem.
Some users report that the reboots start after some weeks of usage. First it just reboots once per week, then it gets more frequent until it reboots once per day.
Factory resets or firmware updates do not help. Some users sent their phone in for repair but not with huge success.
But not every device is affected by this. So far I did not notice that behavior with my phone (G800F).
I guess it is a hardware issue as not every device is affected and the error gets worse after some time.
The only way to diagnose what's wrong with the device is to check the adb and kernel log (at least the last kernel log before reboot might be available at /proc/last_kmsg). But this would require rooting the device which in turn would void the warranty. It would also be interesting if those reboots also occur with CM 12 (installing this will also void your warranty).
So it seems that sending the device in (without a great chance of repair) is the only option that Samsung gives you without loosing warranty.
Alternatively you also might want to wait for the official Lollipop release and hope that this will fix the problem.
If someone with this problem already rooted his device it would be interesting to get the log files (adb + kernel) of the times of the crashes.
Thanks for your reply, so it might be a hardware problem after all

[Q] Note 3 crashes/reboots about once a day

For the last few weeks, my AT&T Note 3 has started randomly rebooting. It can happen when I'm viewing email, when the phone is in my pocket, or even in the middle of the night when it is just sitting recharging. The rebooting is roughly once per day: somedays more than once, other times it can go over 24 hours. The problem seems to have started after I updated to 5.0. I have tried a factory reset, but the problem came back. I called AT&T support and they said that they've had a lot of problems with Samsung devices after the 5..0 roll out, with random rebooting, or the Bluetooth failing, or the WiFi failing. They said that they need to replace the Note 3, but because it is over a year old I must pay $100 for the replacement through Asurion (I have been paying the insurance fee).
Searching on line has not provided much on this problem. Does the AT&T comment make sense? If I need to replace the phone, shouldn't it be for free because the problem was caused by AT&T?
I'd appreciate any comments.
Note that I realize it could be related to an App I use being incompatible with 5.0, but I need to use my phone for work pretty much constantly, so troubleshooting which one (if any) is not practical.
Mine started doing the same thing about a week ago. Till then it was not having any problems with the 5.0 version.
They need to figure out the problem and push out a update. Otherwise it is like they don't care about us, unless we go out every year and buy a new phone !
Problem solved?
After trying a reset and cleaning checking the battery contacts didn't work, I looked for other patterns. It seemed to me that one of the most common times it rebooted was when I checked my email with the K9 email client - something that is always running in the background, and could have caused it to reboot when on charge overnight.
I uninstalled K9 and that didn't help - the phone rebooted after about 9 hours. However, since that reboot it has now gone nearly 48 hours without rebooting. Maybe I was right about K9 and uninstalling it wasn't enough - I should have also manually rebooted the phone.
The phone has been rebooting at random times, sometimes as short as about 5 hours apart and sometimes more than a day apart. It could be that right now I'm at one extreme and it will reboot randomly today. But if it makes it through tomorrow morning without rebooting then K9 was probably the problem.
It has now been over 72 hours since the last reboot, which does suggest that the original problem was the K9 email client, crashing and forcing a reboot on the phone after the Android 5 update.
Problem NOT resolved!
A few minutes ago, roughly 76 hours after the last random reboot, when I thought that the problem was resolved, I heard the reboot tone coming from my phone that was sitting on the table.
So, while removing K9 reduced the frequency of the reboot, it did not solve the underlying problem.
Use Titanium Backup and backup all user apps and data. Factory reset and reflash stock if you want to take the extra step. Use standard Google and Samsung apps for a while. Do not restore accounts or system data automatically. Removing and reconnecting accounts and clear data for an app in app manager are always good quick troubleshooting options. Restore apps as you need them, if you really need them. Favor stability over extraneous features.
.......................................................
Galaxy Note 3 - AT&T (sm-n900a)
Since I removed K9 and rebooted the phone, it has only rebooted randomly once in 5 days: this was at 72 hours, and now it has been up for 65 hours since then. Trying what you suggest would take weeks, given the current frequency of random rebooting. Plus, my phone is used for work constantly - I couldn't get by with just the Samsung and Google apps built into the basic phone image.
For the moment, I will just live with the phone as-is and hope that Samsung issues a new version of 5 soon.
Now at nearly four days since the last crash/reboot, or only one in seven days. At that frequency, it is certainly not worth the effort of trying to track down the secondary cause (it could take months), now that I know that K9 was the main problem.
It has been a while since I started this discussion, with no conclusion. The phone still randomly reboots - only once all of last week, but then it woke me up on a reboot at 4:30 am this morning, and rebooted again while I was checking Facebook at 7 am.
I'm having a rebooting issue as well with my Note 3. It started about a week ago and will do it many times during the day. I have tried wiping the cache partition, doing a factory reset and the other day I downgraded the software from 5.0 to 4.4.2 and rooted it and froze the over the air update from AT&T but still have random rebooting. I have had the reboot issue with and without the SD card installed so I know that is not the issue either. I was thinking it was a software issue so that is why I did all of the stuff listed but now I'm wondering if it could be hardware. I guess I'm just at a loss of what to try know and was hoping someone on here had any suggestions.
I hope that with your additional post that we'll get some answers. One thing: does it happen when sitting idle on charge too, or only when not sitting idle? In the later case, it could be a simple as dirty battery contacts.

It happens both when charging and when sitting unplugged. I even tried swapping the battery for a new one and the contacts and also clean
Well, it was an idea. I did the same thing, buying a new OEM battery and hoping it would help. It didn't. But then again, mine often reboots at night (it woke me up at 4 am this morning), so I knew it was unlikely to be a battery issue in my case.
Yeah thanks for the idea but it seems like I'm running out of things to try
I feel the same. The only thing left would be to wipe out the phone and try it with nothing but stock, non-upgrades, apps. But I use the phone for work, and it can go more than a week between reboots (or less than a day), so that isn't practical.
I might just end up mailing my phone into Samsung to be repaired but now that I have it rooted is there any special steps that need to be done to unroot it? I was just going to do a factory reset and let AT&T android 5.0 do it's update if that will kill the root. I'm not worried about warranty since it is no long under warranty.
Maybe use logcat and letting it run and wait for a reboot to happen so you can see what is going on. However the logs could get big and it might not capture what happens right before it reboots.

Random reboots

I've been getting occasional reboots every couple of days. I wasn't too bother by that, but since I installed the latest security update 2 days ago, my phone has been rebooting constantly. I think today I've had it happened close to 10 times.
I've cleared the device cache which didn't help.
Will try doing a hard reset soon.
Anyone else have had this issue and may be able to point out some options to try?
I'm wondering if this was update related or could it actually be hardware?

I would guess software - it's painful, but back up what you have - and write down all the apps you have. Then uninstall them one every other day, in order of least important apps to you. When the problem goes away, you have found the app causing the issue. If not and you run out of apps, then do a hard reset. Don't reinstall everything at once. Start installing apps, only a couple every other day or so. If the problem comes back then you know which apps...

Freezes and restart... Died. What is the problem?

Hi guys since yesterday I have problems with my phone
the phone suddenly freezes over without being able to interact.
it restarts on its own but without ever starting the operating system in fact it shuts down and does not turn on again as if the phone had died.
the really strange thing is that the phone was fine Then suddenly he started making this mess.
Yesterday after so many hours of problems I managed to start the phone and now it works well but I am afraid that the situation will repeat itself.
the phone has the bootloader unlocked has root permissions, I followed the guides on this site.
But I have had this phone for two months now and these problems never occurred.
where can i start to understand what the problem is?
Mine suddently become all white, with the interface cut in half and moved up. i could do nothing. nor reboot nor shutdown.
after some minutes it turned back normal. i hope its color os bug and realme will fix it
It appears to be a firmware problem. We hope well.
Today did not give problems. This behavior is really strange, what can I install to understand the root of the problem?
I noticed that if the phone never goes into deep sleep mode the problem does not occur.
Now I am registering the log and as soon as the problem occurs again I go into detail to find out the real reason.
I'm trying to create an automatic script that is launched on the boot that practically never makes the phone sleep.
i'm really desperate the phone started to reboot itself.
I would like to try using a system log recorder but I realized that when I restart the phone these logs are not saved so it is impossible for me to verify the reason.
Can any of you help me out?
the phone freezes and then restarts.
Did you achieve any solution ?
No. I'm disperate.
Why don't you flash stock fw /recovery? Just to make sure it isn't an Hardware problem ?
I try but have this problem

@westenlive
The problem appears only when you use data connection right?
If you try to switch off data and use wifi , you will not notice
The problem is because of the the operator, try another sim provider
Yes, in fact, that could be the problem because a few months ago removing the SIM card the phone did not give more problems
maybe you gave me the solution. I'll try

I am now testing the LINEAGE it happened to me this I removed the SIM card and I installed the costum Rom, I made the various customizations and the phone never locked OR restarted.
I inserted the SIM card in the phone worked perfectly, then having messed up with luckypatcher I had to reinstall the Rom.
So I performed the same procedure with the SIM card inserted in the phone and already at the first start it was unstable with reboots.
Currently I have applied for a change of sim card.
As soon as it arrives I will try to remove the sim card Install from scratch The system is to insert the new SIM card only so I can have the mathematical certainty that it is the SIM card
I hope my experience can help someone
This problem seems true, my X2 Pro also faced same issue when enabling cellular data. The phone sometimes loses the signal or the app freezes and perform a phone reboot. X2 Pro is a mid-range flagship phone, and yet this problem should be solved before they start to sell the phone.
Yes this device has many software problems but hardware problems of this kind are not acceptable.
Practically mine has become unusable, as soon as I turn it on after a few minutes of use it start closing the apps by itself.
Then after AN intende use of 30 minutes it start to restart.
This phone is truly incredible
Next time buy ONE PLUS
