[Q] overheating + battery drain problem, and sensor problem. - Captivate Q&A, Help & Troubleshooting

I have read lots of posts relating to call-drop, battery problems, and overheating at Android Forum in Korea. (GalaxyS is originally manufactured by a Korean Company, Samsung).
But I do not see many threads regards these matters. Does anyone experience this kind of problem yet?
1. Battery drain - if I charge it fully, it cannot go last one day so I need to re-charge it before coming home. I think this might be a problem of the current firmware and expect to be solved in froyo stage.
2. overheating - this one is the problem i am currenty experiencing.
regularly, my captivate is 25~30 degree' but when i use a small app, then firsly it turns to be a warm stage and sometimes it is over 105~110 f'. I did not have this problem before, but i think this is a problem of lag-fix. (because the official forum in Korea said that lag-fix occurs overheating problem in M110s so i think it might be the same thing to captivate)
3. call-drop
i think this is a problem of the sensor loacting left-top. since it is too sensitive or not too sensitive, sometimes the captivate assumes the call is already ended even i am still on the phone. OR it does not have an auto-lock feature, so I push the end button unexpectly.
Does anyone experience this?
OR
MY PHONE IS DEFECTIVE?????????
I am kinda so tired to find solutions of these problems every day. I used to use Iphone 3G, and 3GS but I did not feel so stressful like the situation.
If it is a problem from the lagfix, then How can I reset this thing to the factory default one??
(just one click JF6 thing? or change something entirely?)

[Q] Samsung Galaxy i9000 freezes on standby

I have had my phone for about 2 weeks now, and this has been an issue since about day 1. I will set my phone aside while doing other things. When I want to use it I pick it up and press the power button to activate the screen. It seems that about 20% of the time the phone is non-responsive. I can't even receive calls/texts/email while it is in this state. I end up pressing the power button for 10 seconds or pulling the battery to get it to reboot. Everything seems to work fine.
I have heard that this could be a result of a reception issue, and that an update would be released in September to solve this issue. Is this information correct? Has the update already been released? I believe I am running the most current version, 2.1 update 1
Is there a software fix? Do I have a defective unit that needs to be sent in for repair? Is there a setting I need to look at? Any assistance would be appreciated.
you are describing the typical scenario of too many background services and apps running taking up too much resources thus making the phone non reponsive
install Auto Run Killer http://forum.xda-developers.com/showpost.php?p=8123924&postcount=40
then tick all the apps to disable reboot your phone
then you can choose which apps you really want to let lose for it to run in the background
It's also entirely possible it's faulty though
I don't think it is a matter of apps running because there are no active apps running when I am not using my phone.
I guess I am looking for an answer that tells me that this is an known issue with this model and I wiould be better off with a different product, or if I will be safe to get it replaced/repaired.
Ideally I would love to hear it is only a matter of a software patch or something similar.

there is no point helping some one that have their mind already set on their own ideas already
Well that was a pretty useless post. The only idea my mind is set on is to get my hands on a dependabel phone, preferably the one I have. You suggested too many apps running, fine, but unless they run automatically on reboot and/or the 'active applications' window that runs by default is inacurate, there aren't too many resources being used and nothing running.
you'll be surprised what runs under the hood
you can run this and find out

Don't be so quick to assume your suggestion was correct either, AllGamer:

Thus far nothing in that thread has suggested taxing the system too far. In fact, hardly installing anything at all from a fresh factory reset still has this problem and no one yet has really worked out why aside Samsung saying the hardware is damaged. I was on the phone to them today, same thing said.
i read that before and the signal theory doesn't hold truth
if that is the case, every time i go to the toilet, or to the stairs in my office building (way deep in the building) you have Zero reception at all, yet I've never experience the freeze on black screen issue.
same goes with walmart, it's true, most walmart warehouse like buildings have extremely poor cell phone reception inside.
assuming that signal is the cause issue is true, then installing this app will prevent that

I'll highly recommend this app for anyone experiencing the issue and are under the impression the signal issue is the cause of the frozen black screen

I see no truth in the signal claim I've said why in the other thread. But this is the point, it is an issue a few of us are having from all over the place but as of yet there is absolutely no distinguishable pattern. As I say, a completely fresh phone with official firmware and no installs also has the problems. It's a very frustrating situation because no one can conclusively point to software or hardware yet. Samsung keep saying the same thing, send it in, send it in..
it's true the only way to diagnose those will require to be hands on, and run tests to pin point exactly what is causing that.
Eclair doesn't have the option to auto upgrade, so that's definitely not it
Lag is likely, but what, or which stock apps can cause so much lag?
signal even when the phone is having a hard time switching and scanning for a new signal it shouln't keep the phone unresponsive for such a long period of time unless it's lagging
my Old Treo did that, anytime it lost signal and regained signal there was a minor pause, or a looooooong pause if the phone was lagging
if this is the same case with the SGS we just need to figure out which App is running in the background that is dragging the entire system down.
it could be the internal SD which might have become defective, thus locking up the phone, similar to those people that can't get past the boot screen
i can't think of any other plausible causes at the moment.
Well, I can tell you: having experienced the problem a number of times, it is almost certainly not the lag scenario you have described - this is a proper lock-up. My guess (since it does appear to have some correlation to cell switching, or other signal-related issue) is a bug in the baseband drivers, or something similar, resulting in a panic. I might see if there's any way to get a dump out of this thing to prove it, but at the moment it's just a guess, so I'm not going to tell you that's the definitely the reason, or that you're stupid if you don't agree, even though I'm more qualified to do so, since I've actually experienced the problem.

Android is designed to not need auto task killers. It is purely a myth that they are needed whatsoever. This is linux we're talking about here, not windows.... It's possible he has a single app installed causing the issue, but the ideal fix would be to figure it out one app at a time and get rid of the faulty app.

[Q] Some remaining probs with doc 7.6.2

I am trying to get a solution for these 3 problems I am facing with Doc´s 7.6.2.
Maybe it is not a big deal to make it a perfect ROM but these 3 topics are annoying:
I wrote the same message already in Doc´s threat but no answer at all. in 5 min 10 new messages so nobody really takes care for a new question
Hi Guys,
Some problems I do have with the 7.6.2 and for sure I am not alone with these errors.
1 From time to time high energy consumption but sometimes not - this is crazy. One thing I realized when alarm is switched on for all weekdays then it sucks almost 20% in 5h - just in standby mode. Whats wrong here?
2 GPS signal is bad. When you using this tracking tools eg. cardio trainer it looses half time the GPS signal. Was definitely not with older ROMs.
Is that the modem version?
Is this part of the kernel?
3 Bluetooth works but whenever activating and deactivating getting a stupid message about an opp bla bla.
What is wrong?
Who can help?
Thanks
boris03
quite alot galaxy s users have reported issues with the gps reception i used to think its just a driver issue but upon reading into it would seem its related to the antenna. The wifi also suffers from this problem for me it does anyway. you can try out gps booster lite from market it does help outdoors to get a faster fix as for battery issues well im not so sure you would prob better asking in that thread if your still not heard try sending a pm that should work. good luck

1.) Turn off your lagfix, run stock RFS see if you still get the issue.
Do a fresh install dont add ANY apps other than stock, observe for 1-2 days of battery usage.
2.) GPS is a hit or miss, hardware is broken.
3.) Never had issues with BT, I use it on a day to day basis to pass around files at the office.
Are you using one of those OC kernels? Or any of the suggested kernels for the matter? I was using Super Optimized Kernel for a while and the battery drain was outstanding even on the non-OC versions. Switched to SpeedMod 300hz. Haven't monitored the battery though but it seems better with normal usage. Also, what lagfix are you using? For a time I was using the Ext-4 Overkill lagfix from the ULF and I noticed considerably less battery life.
As Earlz suggested, try disabling lagfixes and tweaks and monitor..then if it is better than before perhaps using a different lagfix would be a solution. Try switching up kernels (remembering to disable lagfixes prior). Try running different launchers too. I'm no expert on how these things work and affect battery life, but this is all based from personal experience.
My GPS never worked from the start no matter what firmware/ROM I'm on so it seems to really be a hardware issue as EarlZ mentioned. If the problem came about after flashing 7.6.2 then try reflashing to stock firmware with repartition and installing 7.6.2 again after clearing cache and factory reset. Somehow that (having a super clean install) usually fixes random problems I get with any ROM. I'm not certain if it will have any affect on GPS performance but it's worth a try.
Bluetooth is still working fine for me. Perhaps the aforementioned clean install advice I gave could remedy this.

For now, it seems to be a modem issue from the stock modem of ADJP5

[Q] Random Reboots

Perhaps not random, but possibly keyboard related. I believe I have experienced at least three, perhaps more reboots at various times. I just had one a minute ago when I opened my keyboard from a sleep state (dark screen). My lockscreen had what looked like a Droid X background which caught my attention, then after a couple of seconds, it rebooted.
As I mentioned, this has happened at least twice before, but always when I was trying to do something and (I believe) involving the keyboard. I've never had it reboot in the middle of anything, so the impact is negligible. Add to that how FAST the D3 reboots, it's a very minor annoyance. My old Tbolt used to do that as well, but the reboot time was probably three or four times as long, and it sometimes did it in the middle of something.
Has anyone else experienced this? If you have, sound off and perhaps we can get Moto's attention. If it's just me, then that's great news and I doubt I'll do anything about it since the impact is so minor.
It's hard not to notice since it makes the "Droid" noise when it reboots. Assuming you don't have the same sound assigned to a notification of course.
I noticed it yesterday once (and I just got the phone then too ;-; ), and it was while I was opening the camera app, I decided to open the keyboard for some reason (I don't know why), the phone locked up for a minute and then just rebooted. I also had a temporary lockup while opening up the keyboard while opening Handcent, but it regained responsiveness after about 15 seconds. For me it happens to be something to do with the keyboard while opening apps. We need more people to reproduce this problem so we can get down to the root cause :|
Got two droid 3`s in my house and haven't experience any random boots.

Happened to me while talking on the phone a few times. Got a replacement and it happened again. Never with the keyboard though. Very troubling especially with the second handset.
I have experienced reboots with the camera and camcorder apps lagging, and just general issues with those apps anyway.

I haven't had it happen since I originally posted until today. Today it rebooted in my pocket.
Perhaps it could just be a heat issue. I noticed that another thing along with my other conditions I posted was that the phone felt really hot.

The Droid 3 has a dual core 1 ghz processor processor built inside which is why it starts up so fast. Its probably having these problems because of the new android OS gingerbread 2.3.2 because of how new this operating system is. The first phone designed with the new OS for verizon wireless was the sony xperia which produced surprisingly a very good battery life with the processer designed for gaming built inside that phone.this reminds me of the first droid on Verizon the Motorola Droid A855 where there where some flukes where it would freeze up every now and then. But there were updates that eventually solved the problem. Because this is a relatively new OS there is deffinittely going to be some flukes in the software and there will be updates to solve these most likely coming soon. And especially as more and more users are buying this phone.

1. Everyone knows that it's dual-core.
2. It runs Android 2.3.4. (Hence no root yet)
3. To the OP, no reboots. Had it since the 13th.

I haven't seen another reboot since the 28th but I did have the odd experience last night of not being able to get a new wallpaper to take. In fact, I noticed that it had one of the stock wallpapers on it, the diagonal black and grey bars, but couldn't change it. Then this morning I thought about it and rebooted the phone. The last wallpaper I'd tried to change it to came up on reboot. Interesting but not alarming... unless it starts doing that frequently.
FYI I haven't noticed it running hot at any point.
Thanks for all the input everyone.
Probably seen it do it half a dozen times. IIRC it's not a full reboot, just the Android stack (i.e., same Linux kernel instance).
Have a logcat of one and don't seen anything that suggests where the problem is..just a whole bunch of "com.xxxxxx.xxxx has died" followed by normal restart log messages.
Odd that you all are experiencing this. I have not had a single reboot.

This issue is starting to cause me a good bit of frustration. Most of the time it occurs when waking the phone (sliding out keyboard seems to make it particularly likely). Also seeing complete freezes now which require battery pull.
Phone is now more than 30 days old. It was purchased online. Anyone know the odds of getting a *NEW* (not refurbished) if attempting to return it now? I'm still pretty certain this is a software issue, but may try replacing it in the chance it isn't.
I went into wifi settings and chose to forget all the connections. No more random rebooted.

I wouldn't count on that being the issue.
I've had the problem out in the field (not connected to WiFi) and have had random reboots as well.
Heres a tip for troubleshooting this issue which i 90% guarantee - factory reset your phones put zero apps on them and tweaks, use it for a week and see if u get a reboot.
Then each week after add a single tweak or app(install/uninstall/freeze), may take a yr for some of us since we can't seem to stop downloading random badly coded apps lol...

For me at least SMC, I've had random reboots from stock during the first week. I'm putting it down to bad software for now.
I usually get 1 a week, sometimes less.

[Q] Galaxy NOTE SOD problems.

My brother's galaxy note have been facing serious sod problems since he bought the phone at Nov 2012. After he faced it the 1st time , he sent to SC and got it back. After 1-2months the problem came again and he asked for my help. I persume it was because the malaysian firmware of the ICS was somewhat unstable from what i read from forums here and there. So i changed the firmware to JB duno from which country when it came out in MAC. After a week or so. The problem reappeared . So I just decided to root and chnge the kernel and also the ROM. Changed the ROM to a stock rom and a kernel. Still the problem persist. I'm out of options. Went to the ****ty SC and the idiots just factory reset the phone and give u back. BUNCH OF RETAR*S . (sorry for my languange)
Hope someone here may help me out with my problem. Thanks a million :laugh:
Check all the apps you have installed maybe you find the bad one whose causing it as you have mentioned it comes after sometime of installing a fresh rom and have you tried any aosp rom maybe that will fix the issue

I just installed an aosp rom (PA) and I hope it fixes the problem. Well I've seen the amount of apps installed in the note and its jst a quarter the amount I have in the Galaxy S2 and my S2 works like a charm. The note has been giving me headache ever since I got it from my brother. Hope this does solve it , if not I guess its something else maybe hardware
Phone sod twice on paranoid android. FML! Guess im visiting SC tmrw again.
Same problem with me..
My Note 1 has SOD since 1st time bought it..
be patience to install JB --> still SOD
change kernel to SpeedMod 5.3 --> SOD again
change kernel to PhilZ --> sometimes SOD
I have read many information that related with SOD in galnote 1, my opinion it is related with hardware too.. sometimes
or it is related with kernel... it can not wake from deep sleep..
anyone have another better suggestion to cure this ?
if u're using pure stock rom still facing the same problems then definitely is hardware issues!
if ur device still under warranties suggest bring to SC ask them do a thorough check on it n let them know what's going on actually...
Yes, I use stock ROM still has SOD,
so it's hardware issue for sure...
but I will keep the phone for now because sometimes SC doesn't give solution to this..

I too get this SOD once a week on my GT-N7000
Phone status when this happens:
stock JB(earlier ICS), non-rooted, data connection, wifi, GPS, bluetooth all disabled. Battery mostly above 80%.
Gmail, Google+, Facebook and all other social n/w apps disabled (yes, i am an oldtimer )
During SOD, if a third party calls my number, he hears it ringing, but my handset is dead as dodo (quite dangerous as the calling person may think i am not answering it)
i used to get this when it was on ICS and still getting it after i upgraded to JB.
Most of the time, SOD occurs during wee hours in morning ( i used battery monitor app that logs battery stats every 10 minutes to check the time when this happens).
Sometimes it occurs when the phone is in my jeans back pocket. phone needs a 10 second press on pwr switch to restart it.
Turning off the "power saver" mode seem to reduce the probability of SOD.
i have taken this phone to SC and they re-flashed the JB.
i told the SC chap that i have already done this and couple of factory resets, but he said that they do "much more" than just re-flashing through kies like calibrating camera, bluetooth )
does anyone in the know, know if this is indeed true ?
Thanks

updates...
After 2 days of re-flashing at a samsung authorised service center, i got SoD 2 times in a period of 12 hours.
once last night and second time when i was traveling to office.
Last night i installed some bare-minimum apps back after waiting 2 days for any SoD to happen in "stock" condition.
Well.... i did not pay 30K to use the GNote as just a phone, so installed some basic apps (Battery monitor, Bangalore BMTC, RealCalc, GPS Test, ES File explorer and a first time app StatusLogger)
phone went dead at 1:00 am in morning and as usual there was no wakeup alarm.
phone was warm to touch when it was lying dead. The battery which was 96% at 00:30 AM had gone down to 54% at 7:00 AM.
Status logger did not show any loss of GSM signal which might have resulted in phone transmitting at higher power/hunting for signal etc.
The "radio" seemed working, because when i made a call to the dead phone from my landline, i could hear the phone ring instead of expected "phone is switched off" message i was expecting.
So this has to do with application processor going in some infinite loop.
Uninstalling all apps is NOT an option.
anyone know if we can establish any debug connection to phone and know what the hell CPU is up to in this situation ?
any processor logger that will periodically log all the processes running on phone ?
SOD resolved... not a single one since 6 months.
Hey guys, just wanted to share this info with you, I had SOD's like anything and did all freakingly possible things right from flashing roms to kernels, speed up CPU, banging my head in front of the dumb witted morons at samsung service... to get rid of that pain. What helped me was an app called "WAKELOCK" by darken which is merely 72kb in size but works wonders, not a single SOD after that. What u need to do is.... it has a list of presets that makes sure your cpu stays up. You need to select the preset called "partial wake lock" which is at no. 4, and viola...
It ensures that the CPU is running. No SOD ever after. Also, you need to make it autorun on boot from the options. Yea, it does eat up batter a bit more but its definitely manageable. I still need to charge my note only at night.
Just to be sure, I uninstalled it and guess what, SOD returned. So, do try it, I hope it helps...

Help - Phone Randomly Powering Down

Hi Everyone
Bit of help please.
Having problems over the last 20 days or so. The phone keeps powering down completely at random.
I had flashed No Root Stock Debloated/Deodexed N6 ViPER|Atmos Audiophile 1.6 and after a week the above started.
Fully wiped (including data) the N6 and re-installed from a OTG USB through TWRP. After a week the same random shut-downs began again.
Another full wipe and installed ver 1.7 from the above and within a couple of days the shutdowns started again.
Today thought a different ROM may be the answer. Full wipe and tried [MMB29U/Q][6.0.1][STOCK][OMNI][MOKEE][CMTE][LAYERS] FLUENCE HD9 and the shut-downs are still here.
Seems to be getting worse.
Not using layers or anything abnormal - nova launcher and popular apps, nothing strange. No Kernel optimizations.
Really stumped as to what I have done. Wondering if I have a HW fault rather than custom rom or apps. Going to un-root, lock the BL and give Google stock image a go, unless anyone has a suggestion.
TIA
Any water damage that you can think of? Any parts of the phone getting extremely hot?
You could try ordering a new battery, and see if that fixes the issue, as it is not a software issue.
I'm also having a similar issue, but it occurs when trying to open camera and having relatively low charges(%20). I could not pinpoint my issue exactly but generally complete shutdowns caused by battery problems(temperature, voltage, mis-feedback). Like flyeyes says it is probably a defected battery unit.
Grab some logcats or a crash message. Without them the only thing I can advise is that it is one of your apps causing it or a hardware issue.
Have you tried complete stock firmware from Google with no customizations? If so, does it happen then? If it happens on complete stock from Google you might be looking at a hardware issue. If it only happens on custom ROMS after you set them up, then it might be an inconsistency with whatever apps/changes you make to it.
