Phone Crashes at Random Times - Captivate Q&A, Help & Troubleshooting

Phone Crashes at Random Times - Captivate Q&A, Help & Troubleshooting

So, I have had some problems with my phone crashing recently.
Let me describe the scenario:
1. Phone slows down ever so slightly
2. Phone loses internet connection/shows no service
3. Phone then crashes
4. Turn phone back on and it shows extremely low battery
It is running CM10. I have tried to restore it to factory settings without success. I try to connect it to ODIN, but it either does not recognize the phone or freezes when I start the process.
If any one could help, that would be awesome because I really like this phone, still. If you have questions, please ask because I want help in any way.

Initial thought is...Sounds like ya just need a new battery. :thumbup:
Second thought was...u may have some hardware failure happening.
Also, r u doing any kind of Undervolting or tweaks ?

I have under and overclocked it in the past. Battery makes a little sense seeing as the battery refuses to last more than a day, but last time I tried, the same thing happened when it was plugged into my computer.

Google Nexus One random restarts

Hi all,
I've been having some random reboots w/ my N1. I got the ATT version w/ 2.3.3 Gingerbread (Latest OTA) Also happened while running Froyo
Not rooted, all stock.
Carrier Cable & Wireless Panama City, Panama
I have already wiped the phone via the security menu and via the recovery boot and doesn't work
I have tried to recreate the problem but I haven't been able to isolate to a particular application or moment that could cause the problem.
Could the 3G data connection cause the problem? I also read about overheating but the problem is completely random.
I would appreciate any tips.
Rob

Suggest you try running a log cat to help identify the issue...

Any particular recommendations from the app market?

Long time since I've used one...
Download a few, and see which you like. Some let you filter results by significance, others display in different colors, etc. They'll all give you the same info...

Log
Alright here is the log.
My guess is that this is like when Windows creates the minidumps when you get a BSOD. Let me know what to look for and again thanks for all the assistance.

I think I might have traced the problem to the charger. If use the phone for browsing, youtube, FB, IM, email etc etc. I can open all the apps and use them w/o the phone restarting but as soon as I plug in the wall charger or USB data cable it starts restarting. I have to remove the battery and then put it back and power on and let it charge until full. While charging I can use some apps but I try not to use the phone that much since it might restart.
The phone is the usual warm when is charging so I doubt is overheating
Anyone having this kind of problem?

Giving up
Well after a few months trying to figure out what is going on with my GN1, I decided to call it quits and call HTC to get a replacement.
My guess is that since the problem happens mostly when the phone is charging it could be a overheating problem. The same thing happens when you have a portable or desktop computer with overheating problems, it either starts rebooting, becomes really slow or shuts down.
Lets see if the replacement works better or I will have to sell the phone and maybe go back to iOS. :-/

Help diagnosing freezes and random reboots

I am hoping someone has dealt with either of the following problems, and come up with a way to effectively diagnose and fix either.
The phone - 1101 build; running AT&T Stock KK4; rooted via kernel swap method (using stock KK4 kernel after swap, i.e., do not have clockwork recovery); some AT&T bloatware frozen with TiBu, otherwise stock with root
Problem #1 - roughly once a day, the phone will freeze when in sleep mode; I have had this happen with both the slide to unlock and Exchange PIN lock screen up; when I hit power to wake the phone, the screen wakes up but is unresponsive and then the screen won't shot off again; live wallpaper is frozen in place, but if the phone was plugged in, the battery icon continues with the animation loop. And if the phone is not plugged in, battery power drops rapidly in this state.
The phone isn't completely dead, because if I connect/disconnect it via USB (set to debug mode) to my laptop, the computer recognizes the phone is connected, but it is dead enough that if I call the phone, it does not recognize the missed call. The only way I can restore the phone is a battery pull. Usually it takes several minutes for the phone to come back after this, acting like it would if I had flushed the dalvik cache or installed an update.zip from recovery.
Problem #2 -also roughly once a day, at random times the screen will wake up momentarily, then clear, and I will hear the AT&T boot up sound, after a short while, the phone will run through the media scanner and any other startup launches, acting as though it had been turned on, but the battery stats show continuous uptime throughout. I have had this happen when using the phone, including when on a phone call (and the call did not drop).
I have seen problem #2 on virtually all of the AT&T GB leaks, and it seems to get more frequent the more apps that are installed. I had not seen problem #1 until recently.
The phone is out of warranty, and owned by my employer. I am not due for a new phone from them until July. I've done more master clear/reflash stock cycles than I care to admit, tried replacing/testing for disk errors the external SD card, etc..., and am afraid of doing that and having the problems come up again.
Any thoughts on how to diagnose either of these problems?

Hmm... I don't really think there is an exact diagnosis for any of these issues. Some phones are just problematic like that. The only thing I can suggest is trying a different ROM or kernel, and that might help your stability.

I have the exact same problems. Hope someone comes up with a fix. The only help I can give you is that when the phone freezes, instead of pulling the battery, you can hold the vol up & power buttons for 10 seconds and the phone will restart. Easier than pulling your phone apart, especially if you have it in a case, like I do.

So, the way I see it, unfortunately these problems could be a function of:
Bad hardware
Misbehaving app
ROM issue
Kernel issue
I tried pretty much every leaked AT&T GB ROM and had random reboots with all of them. Seems to track with the number of apps installed, but can't prove that. I have not tried any custom ROMs or kernels.
Since this is technically not my phone, I am trying to avoid doing anything that can't really be undone if I need to turn the phone back in at some point. And I need something that can be a daily driver for work calls and Exchange email, and rely heavily on tethering when I am on the road.
Anyone with ideas on what to test, or how to capture enough log information to figure out where the problem is, would be a big help. Otherwise, I am stuck riding this out until July when I can get a new phone from my employer.

Nothing you do can't be undone, it's just a simple Odin flash away.
Be sure to back up your efs folder before flashing too much

I've used Odin with the various GB leaks; if I go further afield (heck, performance is dicey already, how many more problems could I have with one of the ICS alphas), is it still a straight shot back to stock KK4, or are there other steps to do first?
And before I go down that road, any suggestions on diagnostics (other than yet again pulling apps off of the Captivate to see if one of them is the culprit...?)

You actually might have less problems on ICS. But it all depends. You can always get back to stock with one, bootloader-free, safe flash. Diagnostics wise, there isn't really much you can do besides removing apps. I would only worry about the ones that are constantly running in the background, as they could possibly be screwing with the phone while in sleep. I think it's unlikely that this sort of testing would actually help though. I still say try something different.

I am having the same issues except in my case I have tried to recreate the conditions and check memory and I am close to maxing it out. Part of my problem is that I come from a Palm background and I have found that Android, or at least the Cappy, is not as responsive (I was really spoiled by Cards on my Pre) I was thinking that my Android noobness is causing me to push the phone too hard and locking it up. FWIW, you might want to check memory issues

[Q] screen will not stay off.

Hi every one this is my first post and was wondering if anyone has had this problem come up.
My wife has the I9000 and a couple months ago it started to show this problem of everytime the phone is in standby the screen keeps coming on or about a second or to then goes off for about a second the then on and it will keep doing this till it runs the battery down.
I have tried to do a complete ROM install fresh and factory resets and custom roms and the phone still keeps doing it. is there anything i can do or is the phone beyond fixing unless i take it apart??
Thanks
Andy

Hi,
This sometimes happens to me also. Reflashing does not seem to help.
The one thing that seemed to do any difference was to turn off the device, remove battery, sim card and SD card. Then plug them all back in and start the phone.
This sometimes worked or at least minimized the number of problems, but not a permanent solution.
Although your problem could be something completelly diferent.
No arm in trying this suggestion

Hi thanks for the reply.
I havd tried that. Atp the moment it has no sc card or sim card as she got a galaxy mini to use for moment and it still dose the same thing.
It is quite anoying as ya have to have it plugged into charge all time as batt drains really quickly.

One possibility is a hardware problem. Maybe one of your phone's buttons (home, power, or volume) is grounded and keep on contacting.
Another possibility is a program that is running automatically. If you're on ICS or JB, you can check your running apps in Settings/Apps/Running and see if there is a running app that can be stopped without affecting the system...
Just a suggestion.

is there a known solution for the "screen-turning-on-problem"?
friend of me has the same problem with non-rooted galaxy s+

The phone is on stock gb fresh install.
Might have to try and open it and see if anything wrong.

[Q]Note N7000 freezing even when room temperature is 30°C

Hi guys. My SGN is permanently freezing while booting. Suddenly the red lines appear and phone is stucked. It stucks on boot logo, or boot animation, or after successfull boot into system. It looks like this:
http://dl.dropbox.com/u/61718936/IMAG0003.jpg
Phone becomes quite hot on the back near camera.
I bought phone with stock 2.3.6. It was running for about 2 hours and i made OTA update to 4.0.4. It started to reboot itself while i was using it. So thought, i might use custom ROM to get rid of this freezes and reboots. But no change. Even on 4.2.1. I reverted back to 2.3.6. I noticed, that these red lines changes and moves (or even whole screen becomes red) while i'm twisting or pressing phone on various places. So i think, there is cold solder joint somewhere on motherboard. Maybe on graphic chip, because i didn't notice this problem while in recovery or download mode.
Can anybody help me with this problem, or point me on right place to look at on motherboard? Thanks in advance.

Seems to be defective device. Check with service center.

If you're able to, run this app to check for errors, I take it you have root. If it crashes mid scan, you've got problems with your emmc.

Frozen Note
I hope you will find a solution for your problem.
But I have to admit I had to smile ("grinsen" in German is a much better word for it) when I saw your title:
Freezing even when >30°C

i'm not able to run device anymore but i already tried this app for checking emmc and this is the one with that bug. But it doesn't matter, because i was flashing only safe kernels, and i don't think this emmc is problem. I think the culprit is graphic chip, or CPU, or CfRF (Chip for Random Freezes)
I was not able to find any similar problem. Tomorrow, i will try to put device into download mode, flash any custom safe kernel with CWM, leave device in this recovery, and see if it freezes again. If yes, the only option is to get device warmer for a few degrees (300-350°C with my heat station haha ) and i will see if there was any cold solder joint. If not, device will be dead anyway so i have nothing to lose

guys i've made a small progress. I put a pressure on back side of the phone near camera, and i turned the phone on. It successfully booted to system. When i stopped pushing phones back, red lines appeared immediately and phone freezed. When i start to twist phone in hands, lines were getting bigger or smaller. When i pressed the back cover again, lines disappear (but phone was still frozen).
So now my task is, to find out, which chip is badly soldered.

You guys started having strange issues with ur notes. Maybe its something like a self destruct programmed on your phones so that after a year or two people will switch their phones. Besides the bigger the phones are getting the more issues they are having.
A phone should be like a device that shouod work flawless, in case of emergency one is needing to make a call and found that the phone freezed.
Sometimes i blame everything to android. Despite years of open development. Its yet not stabilizing, i guess because of it being open source vendors are putting crap in it making it more vulnerable to issues.
I dont rely on android rather i use a cheap phone for calls and text or iphone. Its just good for internet, ebooks, movies, music and camera.

Try pulling out the battery and then let the phone dry like a pair of wet socks. Clean the contacts and fit any loose thing that there may be.
Check your cable, if is loose or not, this way you could find if there were any unwanted sparks applied on the device.
Notice how it gets hot when is plugged in and you're using it? the battery reaches quickly 55 degrees which is not optimum, wait to cool to below this temperature.
My condolences in this sad event. Take care.

[Q] A very strange rebooting problem.

Regarding: Samsung Galaxy S3 Mini GT-I8190 - SIM unlocked version
Hello eveyone.
I'm having one of the strangest problems I've encountered with a phone before and I just can't seem to track down the problem. Please read this thread with an open mind as from what I can tell this is a unique issue that sounds like normal issues.
The main problem is that the phone keeps rebooting. From the get go this sounds like a normal issue with either the battery or power switch but here is the weird part...
It only happens when the phone is fully charged!
IBackground
I have had the phone since release and I have only ever used the stock rom that came with the phone. I don't really use phones much n general except for using it for calls texts and BBC news. I didn't even have a SD Card in it until after the problem started. Everything was running great, I never had any battery problems at all, and then a couple of weeks ago my phone contract expired with Orange and I decided that I would get a SIM only plan with EE.
While waiting for the SIM card to arrive in the post I charged my phone up one day and noticed that I had to power on the device. The phone seemed to power on fine, I could use all features of the phone, but when I turned the screen off for more then 5 or 6 seconds the phone would restart. There would give no indication that it had turned off or that it had powered off in anyway. It would simply just be blank, I'd press the power switch, and it would vibrate once and begin its start up procedure as if it had been turned off completely.
Here is where it gets weird, the phone will keep cycling on its own like this until the battery drains itself through constant reboots until about 85% juice, at which point it begins to operate functionally.
I heard that some people say they had problems with the power switch. I figured that if it was the power switch it then the problem would be consistant and would continue giving me problems when the battery was below 85%. I think I can rule out the power switch as faulty. Naturally I came to the conclusion it must be software, perhaps an APP installed which was incompatible. I tried all sorts of things, regardless I came to the conclusion it needed to be factory reset. Factory reset didn't do anything, still does it. My next thought was Firmware, it must be the firmware that was corrupt. I went through tutorials and rooted my phone, installed recovery software and ended up installing Cyanogenmod 11 (Which looks really beautiful btw, wish I had done that sooner) and buying an SD Card too do so. Still the problem persists! I read that some people had problems with swelling batteries, I replaced the battery completely just incase. £10 wasted, still does it.
At this point I'm starting to get confused. I started thinking perhaps it was the cable providing too much charge to the device, over charging somehow. Tried a different cable and a different power source. Still the poblem persists. I made sure there was no dirt in any of the connectors incase that was causing something. No joy.
So to summerize:
1. Factory Reset
2. Replaced Battery
3. Changed power leads
4. Cleaned device
5. Flashed to completely new firmware
I've completely run out of ideas on what it could be. Why would the phone operate absolutely fine under 85% power? Its just weird! I'd appreciate any help some one could provide me. I've not seen any one else with this problem on the internet. Please let me know what you guys think.
Thanks
Craig.

Sorry to hear about this man!
I am completely stumped on this one! You've basically done all the basic solutions but to no avail. I had a problem similar to this where my device would reboot randomly, whenever it wanted to and in my case, the solution was to buy a new battery and that actually worked. I've had the battery for almost 2/3 months now and it's still going strong.
Back to your problem, I honestly don't know of a solution. I really wish I could be of help but as I said, you've already tried the basic solutions.
Again, sorry to not be of much help!

I think I have the same problem as you did. After suddenly dropping and rebooting, my battery level jumps back up when the phone starts, and again, and again. The phone is functioning normally only when plugged in. I also presume that it is a battery problem, but the fact that the battery level rises back after dropping, makes me wonder.
EDIT: Problem solved with buying a new battery.

Sorry to jump in, just curious, did you solved this? If you do, hope to hear your solution, might help others in future
