This seems to be happening with every ics rom I flash. I first flashed ics to my phone when it first started to be ported to the Captivate.
My phone has suddenly started rebooting every so often (every 20-30 minutes.) My phone usually does this when it gets to about 60% battery. I have already tried calibrating the battery and using a different battery. Neither method has worked. Is anyone else having this issue or know how to solve it?
EDIT: meant to say shutting down not rebooting. Also it doesn't shut down on me while I use it, only when I set the phone down and the screen turns off.

That's generally hard to troubleshoot, but the first step I would take in this situation would be to bump up the lower frequency voltages. Of course you'd need a different kernel to do that. Try Glitch or Semaphore if you want. If you've never played with that stuff before, there is some necessary reading involved before you can know what to do.
This has been an on-going problem with Samsung Captivates, ive had that issue, Ive tried all the above. Including all the ROMs on xDA, and also different methods of flashing. And ive had no luck either. I went back to GB. If u do find a fix, let me know.
In my opinion, i think its our phones, some can handle it, and unlucky ones cant. Sucks.
same issue with me. the last four digits of my IMEI are below the cutoff point of phones who would eventually have the issue.
Every single ICS rom shuts off my phone randomly. ever since I went back to GB, it has been running fine. tried a bunch of stuff to, but nothing works.

All, having a weird issue. I was on the phone yesterday using an automated menu system and my phone restarted. No rhyme nor reason why. It did that repeatedly throughout the day. I tried flashing a new ROM version, Phoenix 6.0!!, with no luck. I tried a normal restart, power down and then up, running a virus scan, pulling the batter for 30 minutes and no difference. The phone continued to restart. I finally got fed up and my battery was almost dead so I turned the phone off.
The phone was off for probably 5 hours and I charged it while off. I restarted the phone and transferred all of my content off, expecting to Odin back to stock and reflash Phoenix. The phone seemed to be behaving so I left it alone and plugged it into the wall for the night.
I got up this morning and everything appeared to be good. Went to work and still no problems, phone had an uptime of over 12 hours. Which would be what I would expect. Had the phone on my desk and I noticed it had restarted. When I mean it restarted, it went back to the boot animation and then loaded to the android screen and performed media scan and all my apps loaded on the home screens and services started up.
I went back to Settings->About->Status and the uptime was 18 hours now. So even with the restart, the uptime was still counting. Needless to say, I'm at a lose. Can't isolate any event that causes this reset or any app. Could I have gotten something from the automated call system? Is something just weird. I had been running Phoenix 5.2 for a few weeks with now problems so I'm confused. Any suggestions would be appreciated. I will probably flash back to stock and start again but I'd like to isolate this problem if possible.
To the best of your knowledge, no apps were just added, our settings adjusted?
Either way I would odin flash master clear. May even run stock for a but to see if behavior stops

sounds like a problem with the infamous 850-1900mhz handoff....
if your signature is accurate, that modem you are using is 1900mhz only i believe....it doesnt support 850, so if you are in an area where its trying to hand off to 850, it will cause a soft reboot.....i have seen it a million times myself when playing with the first run of i9000 roms

Hmmm...I have been using an i9000 roms for a few months with no issues. The last modem I was using was I9000UJK4, I think? I don't know without flashing back, whatever came with Phoenix 5.2 ROM. I had zero problems. I only flashed to that modem/ROM, Phoenix 6.0, in an attempt to fix the soft reboot.
flash just the JK4 modem and i bet the soft reboots stop. what you have listed there is i believe a 1900mhz only modem....

I will try that, when I can find it to download but the problem started with the JK4 modem. I was running Phoenix 5.2 with a JK4 modem and only flashed to the new one in an attempt to wipe whatever was causing the data.
Flashing UGJK4 right now, I'll see if that fixes anything however I'm not super confident since the problem occurred originally with a JK4 modem.
Update: Rebooted once after modem flash. Going to wait for a bit and see what happens.
if that doesnt work, i would think its a problem with your hardware

If the modem switch doesn't work, I'm first going to flash to stock and master clear. If the problem goes away, I'll flash to Phoenix again. If the problem comes back, it'll have to be part of my SW. If the problem persists at stock, back to AT&T for a refurbished phone.
Update: Looks like things are pretty stable right now. I'm not super in-tune with how the modems work but is there a way to allow the JK4 modem to use 850 or 1900 speeds, like an auto setting that will choose the best one. I use SGS tools for secret codes so if its in there let me know. So far so good, thanks pirate.
Reviving an old thread because I am also having soft reboot issues.
Unlike the previous poster, I am not using an i9000 based kernel. I am running the latest leaked Gingerbread for the i897 (JK3), rooted via Fugu kernel swap method; the only other tweak to stock has been to freeze via TiBu the AT&T Tethering Manager. I am even using the stock launcher as I try to isolate what is causing this.
The phone goes through spells where it will soft reboot every 10 minutes or less, and then periods where it will go days where it is stable. I have had this issue with multiple versions of the 2.3.3 and 2.3.5 leaks and am nearing wits end figuring out the cause.
Before each flash (and I have flashed multiple times with different stock leaks) I am wiping data and cache via recovery (I do not have CWM installed), then restoring apps only via TiBu. I have tried to be judicious about what I reinstall, but have not been able to identify if there is a misbehaving one yet.
I suspect this is software and not hardware, since I had this problem on my first Cap and have already done one warranty exchange; the external SD card, though, is the same for both.
I've looked for kernel panic logs and have not seen any, and have yet to find a good way to trap what is causing this.
This is my work issued phone (does Exchange sync and has company policies sent to it), so I am loathe to go all the way to a custom ROM, even though I realize that I voided the warranty when I rooted and went to leaked ROMs.
Anyone have an ideas as to what could be causing this, how I can isolate the problem, and hopefully resolve it once and for all? Worst case, I could go back to Froyo until AT&T finally drops the promised Gingerbread update, but I had different issues with Froyo with Market updates not always finishing and apps on the SD card not always being recognized.
I tried to search but alas Tapatalk isn't very good at that.
I bought a Captivate via eBay. Before I press to return it, is there a fix or ROM that fixes the dreaded random shutoffs? I tried resets and the GB Serenity ROM but alas I'm still encountering it...rather frequently. Every hour or less it'll shut off. So, other than the battery draining Captivate Keep Alive app...is there a real solution?
barring anything physical with your phone .. I have not had any sleep deaths or random reboots since switching to Fusion-CM-ICS-beta. It used to be a chronic issue with my phone.
Thanks for the fast reply Garyth. I'll give it a go.
I've heard the aosp roms seem to help the problem (this includes the ICS roms). They use different drivers than Samsung roms.
So far, so good. Data is consistently faster as well. Thanks again!
Hmm. Still getting random yet pervasive shut downs.
I believe this was a known hardware issue as well. There is a thread around somewhere will effected build numbers.
I saw that thread and don't believe mine is in the range. I'll be calling the seller tomorrow anyway.
Not sure if you are in the same boat as me, since the IMEI of my phone does fall into that catergory of the "recalled" phones, but since it was out of warranty by the time I saw that post, they wouldn't exchange it at the store.
At any rate, here's what I've gone thru:
Back in the Froyo times, I "think" CM7 fixed the issue, but I was too fidgety at the time so I was always trying new roms so I don't remember 100% if that was true or not.
I read somewhere that this could be caused by the battery shifting around due to temp changes as it charge/discharges, and that you should put some electrical tape or whatever to make sure your batt. made good contact. Didn't work for me at all.
So finally what fixed the problem was Captivate Keep Alive app, it's in the market.
First I tried it with two ICS roms: ICSSGS and Fusion, with Platypus and IcyGlitch kernels. The app work fine with a setting of 85%, but I was getting "charge death" as well, which I've never had before.
So now I've rolled back to KK4 (Serenity ROM) with the latest Corn kernel, and for some reason I have to set the app to 80% charge but works.
There'll be definitely an increase in battery drain, but for me it hasn't been that bad.
I used to have that problem when I first got my cappy, had froyo KB1 on it, and it would randomly shut down. Eventually when I got into hacking the android, when I finally updated to newer bootloaders, the problem went away. Though I can't recommend flashing bootloaders, since you can hard brick your phone if unsuccessful. Just saying that's what seemed to solve the problem for me.

But what bootloader fix that to you?
Mine only rebooted randomly once when on eclair. Haven't had a problem in gb or ics.

That would help if eclair wasn't completely useless.

I tried Captivate Keep Alive. Even it didn't work. A replacement phone is on its way. The IMEI was actually affected, but I didn't realize at first because I only looked at the last digits. Apparently was a really early build. The seller photographed the new IMEI before shipping it out so I could verify.
I have Dark Knight's 4.0.4 ROM since 2 weeks ago.
At the moment, and I hope it remains 0 reboots.
Just wanna share with you, is up to you to try it....
http://forum.xda-developers.com/showthread.php?t=1501615
By the way, with this ROM also I got the best Quandrant Benchamark score (2400) without overcloking...
I'll keep that in mind but I got a replacement that works really well. I ended up getting it from another seller though.
I have frequently been flashing/testing different rom's on my Cappy's but recently ran into a problem which I originally thought had to be the rom(s) or oc/uv but apparently is not.
The issue is resetting after the phone has been screen off or asleep for a half hour or more.. and recently been rebooting during calls....never while using the phone for anything else.. but most often when i'm not using the phone and i go to wake it up, I notice it is off and have to turn it on only to notice i missed some calls,etc..
This started about a week ago. I have since wiped the phone at least TEN times. Different ROM's almost every time. I have gone with STOCK voltages and clocks.. i even changed the min voltage to 200 or higher in case that was causing the sleep issue but i never had the issue before.. but it's still turning off a lot.. and this is my second cappy, the one that I dont do much oc or uv..like the other that I have OC'd to 1.785 Ghz stable... this one is usually run at 1.1 or 1.2 with little or no uv...
I've tried different modems to see if that was causing the restarts during calls...and have wiped the phone with different rom's so many times...
what on earth can cause this? is the phone's hardware in some way damaged? Could previous tweaking have caused damage or could the phone just be toast? or am I missing something?
The phone still boots fine and if i'm using it i can do anything and everyting (including oc and uv) for hours...but if i make or receive a call, about 50% of the time it will restart..and if the phone goes to sleep..for the night or just for some time during the day..usually it will be off when i go to turn it back on..
any help? thanks

If you have tried many different modems and ROMs then i think your best bet is to flash back to stock and see if the problem persists, if yes, well then it's hardware, if not, then you may have had a buggy kernel or perhaps your phone just didn't like the ROM you ran (this has happened to me with several versions of DarkyROM, and yet other DarkyROMS work perfectly) Good luck!
Hi all,
I am completely running out of things to try and do now.
After installing Android 7 on my Note 5 I had the strangest issue that i in general have never seen on a phone. The screen is simply black (which isnt that strange) and the phone is fully functional. Bare with me, after reseting it multiple times so it would finally come on the screen goes crazy and turns goes into so many colours (if it turns on that is). Its either that or jumps all around the phone, quite literally it glitches out completely. Its like one of those virus cut scenes you see in movies, it goes different colours, glitches out, jumps around and completely misformats.
From the beginning i knew this was not a broken screen.
So far i have tried.
1. Factory reseting the phone. That gave me about 5 minutes of normal use until i locked the phone and it wouldnt unlock again.
2. Factrory reseting multiple times... again to no avail, it would work for short periods of time and glitch out again.
3. Reflashing stock Android 7 in Odin. - No avail.
4. Flashing Dr.Kretans Rom... worked for 1 day which made me so happy and think that the problem was solved but then the same problem persisted.
5. Installing Arters Kernel.. (arter97-kernel-n920cig-22.0) Nothing... literally did that today and still NOTHING
6. Re partitioning. Quickest process and no avail.
In more detail, if the phone does sucessfully boot, and bare in mind sometimes it takes more than 2 hours to get ANYTHING on the screen (including recovery which doesnt boot up either until the initial apperance of something on the screen)
I tried taking the phone to a phone shop before doing anything myself and since in England this phone was never released theyre refusing to touch it. I tried calling samsung and they dont want to do anything either cause its not a UK variant.
Could someone please tell me anything else i can try. I feel like im totally running out of options here.
My phone details are as follow
Galaxy Note 5
SM-920I Singapore Singtel Variant
Running on 6.01 (i downgraded from Kretan)
And the kernel is the one previously mentioned v.22.0
I would appreciate anyone's help or suggestions so much at this point. All these problems started since the 7.0 update a few weeks back :/
Oh its also running TWRP recovery (arter97-recovery-n920cig-22.0-twrp_3.0.2-0.tar)
Hey all! New here. I just soft bricked my phone, i woke up to it not booting. I tried various fw in Odin, but no success. This is my day to day use phone, I don't have anything else, so I'd like to make it work again ASAP, hopefully without factory reset.
Hi
what manipulation did you do to get there before flashing a lot of stuff in odin?
I've been just pressing the buttons all around, then I read about Odin, so I tried it. Now my battery died, let's see if I can get to wipe the cache...
Update: no success. Is there a way to get it into recovery? the old volume up+bixby doesn't seem to work.
Sometimes its because the recovery itself is error so that button combination is not working..
Charge your battery until full, then factory reset it with odin, let see if that works
But before you do that make sure you download correct fw that match your phone model. dont try all fw available there, make sure you download fw for SM N950F..
Well it worked and it broke again... Back to square one.
Your infos are kinda vague.
Did you modify your phone and it got triggered by user-action, or did it hit the fan by itself?
I think it was a suicide attempt, I never flashed before, only major thing was just a battery change in a samsung service last summer. It's weird, because since last time it turned on again, but seems like the wifi didn't want to communicate, plus as I look back, sometimes it restarted when I touched the wifi or some random setting. Somewhere else I read that it could be a motherboard failure.

This was happening to me too before my phone just started bootlooping to recovery
Well it's been a few months, so a little update: it still reboots sometimes all out of nowhere, but now I have a different problem: tried to log into a mcdonalds app and it says it detects a security issue. Not that i'll cry over it, but definitely interesting. Anyway, I really think this is some sort of hardware issue related to wifi, because every time it started rebooting, about one out of two times i was turning the wifi on or off. Also sometimes the wifi just wasn't available or working, strengthening my thought. As I read on other threads, this is probably some manufacturing/serial issue, that just happens to come forth after all these years. Probably the last time I bought a Samsung...
