Random shutdown solution!

Random shut down solution! At least for me.
My phone shuts down pretty much 2-5 times a day since i got it. No matter what I do to it. But I tried the app, load monitor and enabled WAKE LOCK and my phone hasnt rebooted in 4 days!
Anyone else had similar experience.

Umm, not meant in an asshat way at all man, but your real solution is to take that sucker back. I wouldn't put up with that at all. Bad phone. Just my opinion.
From a phone on an app

I have to agree with the post above mine. I believe it's a hardware issue and that you should return it for another one. I have two captivates and neither I've of them have ever had the random shutdown issue.

Truth is, the phone is bad. Ask for a warranty replacement. I went through 2 phones until I got a good one with no issues. A perfectly good working phone should never randomly shut off as mine were doing before (4-10 times a day) Even setting Set-CPU to 1000mhz 100% of the time didn't fix the other phones I had. Hell, even leaving the screen on the entire time one of them still shut off once.

Others have found that the "wake lock fix" has not worked (although it initially seemed promising). If your shutdowns recur, exchange the unit. That's been the only remedy to date.

Did you have set cpu installed? That's what happened to me after installing set cpu. Sometimes it would lock up after the screen went off & sometimes it would just reboot randomly. I got around this by setting the min clock speed to 200mhz. I think set cpu sometimes undervolts the cpu when scaling especially at 100mhz & at 1000mhz when the screen is off. If it did that stock then I would definitely return that pos! Wake lock will kill your battery life.

Well we will see. I was in the process of a rma and just got the phone last night.
I see if the new one has any issues. By the way this will be my 4 th phone(3 through the first month, this one through rma). So the get another phone idea kind of sucks.
Just a curser glance at the back of the rma phone and I can see its different. So maybe I'll get lucky on it.

Same here, I'm in Australia, I bought the phone from the US, It used to shutdown 3 - 5 times a day, especially when it's fully charged. Wiped the phone (Internal and external) and now it's solid stable. no special apps or settings or whatsoever. It's a little bit weird though.

I think the problem may be from the phones overcharging. Mine was brand new and I left it on the charger overnight then took it off the charger in the morning and when I came home from work it was powered off. It may be a safety feature built into the phone and not a defect. I had it happen to me twice when I didn't take it to work with me after charging it all night the night before.

I thought the same, but last night I forgot it on the charger with no problems at all, No shutdowns... Strange...

It happens to my Samsung S Vibrant and I *think* I can reliably reproduce the issue, at least on my phone.
Steps:
1. Go to a spot where you know it has failed, for me this is my office because it has bad reception and it seems to only shutdown for me when there is bad reception.
2. Make sure 3G is turned on and open an application that uses data.
3. Wait for the phone to sleep, do not hit the power button or anything to make it sleep (not sure if this step matters)
4. Wait ~30 mins without touching the phone (You can play music with it while this is happening if you want, the music will stop to let you know it's failed)
5. Try to wake up your phone, it is now dead.
I'm not sure this will work for everyone but last night I could reproduce 3 shutdowns in an hour and a half. And reproduced about 7 shutdowns yesterday when my phone only usually shuts down ~2 times a day.
I'm testing out all kinds of software permutations (disabling stuff, installing things like Captivate Keep Alive). Nothing has worked so far, my guess right now is that the problem lies in the Pattern Unlock feature so I have disabled it, I read that on a forum somewhere.
My guess is that if you have too much running in the background it might take up too much cpu or ram so that when the phone tries to come out of sleep it can't get enough CPU power to come out of sleep and therefore gets stuck in a kind of limbo. This theory could then be releated to the SetCPU problem when you set the CPU too low when it sleeps the issue occurs.
Moral of the storey is I have no idea what's going on, but please post if this works or doesn't work. Maybe it will shed some light on the issue, or you can tell me I'm wrong so I can give up. Let me know if you have Pattern Unlock enabled...
Luckily I'm not past the 30 day mark and I'm exchanging for a new Vibrant tonight. Wish me luck!
UPDATE: It's not the fault of Pattern Unlock, just reproduced the issue with it turned off.
UPDATE #2: Got my second Vibrant, just reproduced the issue within 30 mins of getting into work in the morning.

My Captivate used to shut off once every 2 weeks. Now it's doing it 4 times a day. However, I just found this app:
http://uk.androlib.com/android.application.org-bluesteel-cka-qxnim.aspx
Looks promising. I hope this works.

My wife's stock Captivate has been doing this for a week or two (our phones are about 6 weeks old). My rooted Captivate has -not- been doing it. We both have the same "plug it in all night" charging pattern. Hers will be going back shortly.

Tha'ts not true.
My phone was working fine. Then I rooted it. Then I started sideloading bunch of apps. Randon shutdown started to happen. I started tracing back and deleted apps one by one. Didn't work. Replacing the phone was out of the question because I live in Canada and bought the AT&T phone cash off a seller.
SOLUTION:
if you have had SetCPU (or overclock app) and had it to anything to your phone, this is what you got to do.
Run the SetCPu again, and make sure that you do Max 200mhz and Min 200mhz.
Reboot the phone.
Then go into SetCPU, disable autodetect. Then uninstall app.
No more random shutdowns.
It is NOT a hardware issue.

I can confirm that the App stops my phone from shutting down.. unfortunately I have to set it to 65% charge for it to work (whereas others can leave it on default 80%).

Found my issue, it was happening when my phone was jumping between the 850 mhz band and the 1900 mhz band. It would freeze and only happen in areas of bad signal. Locked it on to the 850 mhz band and havent had a freeze since.
100 hours of uptime and counting
http://forum.xda-developers.com/showpost.php?p=8612667&postcount=386
I have also heard that some phones experience the issue when fully charged and that putting a wake lock on your phone with captivate keep alive will solve the problem. These are two independant issues.

i'm not really that knowledgeable about how the phone interacts with different bands, but i'm trying to fix this problem as well and i'll try anything. are there any side/adverse affects to locking it onto a single band?

Has anyone tried removing the sim? to see if it still turns off?
The problem im having is when its near full and goes to sleep i need to turn it back on (like it shuts off) but i tried removing the sim and has not had this problem

[Q] G2X Shutdown issue

my g2x shut down and wont turn on..i charged it over night... it took like 3 hours to get to 99 percent...it took a while....i left it over night and this morning it was off and wouldnt come back on...i called tmobile and they told me to try to get a extra battery..but no one has em yet..and they cant exchange it cuz i bought it off of craigslist...anybody know anything that will be helpful?

Try holding down the volume down and power button at the same time beware it will wipe the device but may get it to boot not sure

promptly go back to the person on craigslist and slap them in the face. I hope you @ least got a deal on the phone. Hopefully you shouldnt have to wait to long for replacement batteries to be made by some manufacturer. good luck

It happened to me 3 times today, my phone shuts down and won't turn back on until I take it out and put it back in, it's because it gets overheated and the phone shuts down itselfs, it must be a defective battery that makes the phone really hot when it was in my pocket.I went home and replace it with another battery (from another G2x i was about to send back to Tmobile because of bad light bleeding from the top corners), and everything works perfectly. I start to love my phone a little better now.

That same weird thing happened to me one morning I was scared but all I did was took my battery out let it cool out for a while because I noticed my device was hot then it said system check under the LG logo then booted up

its a shame you didn't just pull the battery. its not a hardware issue and this android build isn't the first to do that.. there are some issues with this build of android its obvious.. give some time more builds will come including cm7 which you will find rock solid soon enough.

I had two g2xs with the problem, and I'm pretty sure it's a hardware issue.
When I charged it, I noticed the back got really hot.
On that suspicion, I went to a different TMobile store and got one from a different batch, by looking at the manufacture date on the back of the box.
No more problems.

p.s. I'm pretty sure a software "fix" will involve underclocking/undervoltaging. Lame.

Probable fix
Hello,
So we’ve been working on this issue for quite a while. And have come up with a semi-practical solution. This might interest some of you, who have this issue.
Issue:
Both I and my friend opted out to purchase the new and wonderful LG g2x phone. After receiving the phones we came against a very similar issue. The cellphone unit would shutdown/turnoff during the charge [car or wall]. The shutdown would occur around 95% of battery charge. In addition the phone would get hot. After the shutdown to start the phone would require pulling the battery out of the unit and reconnecting it again, otherwise known as: Perform a battery pull.
Trials:
So after doing some research and funding out that LG is literally doing nothing about this issue, [great testament to their corporate integrity] we decided to take on this issue. At first we also believed that it is, indeed, the battery that gets heated and goes offline after reaching some temperature. After recognizing the poor quality of the battery, I’ve decided to purchase a better quality one online. No surprise really the phone would still lockup at 95% charge.
At this point I took it upon myself to resolve this issue with what resources I have available. I am an MIT student and have a high tech engineering lab available at my disposal, in addition to some free time with a winter break and all. Anyways, I pulled the phone apart and this is what I’ve discovered…
Discovery:
So inside the phone right next to the 4 connecting diodes that connect the battery to the cellphone unit are 2 semis [semiconductor hubs] that are responsible for providing battery charge information to the cellphones cpu [central processing unit] in addition theres also a line running to those semis that probably carries some sort of information [current] that the semis are also responsible for.
The first approach that we took was through the hardware, and killed that additional line and allowed the semis to only be responsible for the battery charge. The results were somewhat positive. Although the phone would freeze and glitch like crazy it would not shutdown with a subsequent necessity of pulling the battery.
We also noticed that it was the two semis that would get hot actually and lockup shutting the phone up and requiring a battery pull. The reason you need to pull the battery is because the iodes would overheat and completely glitch out, also even though the phone was now powered off there still was a current running between the battery and the phone. Only the battery pull would allow the diodes to drop the charge and reset to the position for the phone to be functional again and able to power up.
Solution:
So the idea was to find a software solution, which would free up this one line running into semis and allow them only to carry the responsibility for reporting the battery charge to the cpu. Believe it or not the first thing that came to my mind was the solution.
The app called Advance Task Killer (ATK) [available free on the market] proved to be useful. I do understand that this program is not very effective and only kills running progs in the foreground. However, that single line is also not very important to information transfer and becomes useless after you clear the cellphone’s foreground information transfer.
Basically when you run atk the line becomes inactive and you can charge the phone without any lockups. I’ve been doing that for about 10 days now. Discharging the battery to about 17% and charging it all the way up again and the phone has not yet turned off once and required a battery pull, nor has it been getting hot.
The idea is to clear the line prior to putting the phone on charge [car or wall]. So what you do is run atk few times [twice at least] then plug the phone in. this worked for both me and my boi here @ mit. After a week plus of testing we decided to release this onto the public.
We both a running stock lg g2x gingerbreads and have not tested it on any other roms, however, I suspect that it will have a similar effect on more leaner and cleaner roms like CS7.
Hope this helps those who are still struggling with this issue.
P.S.
In addition I would like to add that we did pull the battery apart in the lab and found that the stock battery was complete SHAYT! Some of the cells were cracked and overall it was just poorly manufactures. Cracked cells inside the power unit diminish its capacity to carry charge by a factor razed to n^power. Also may cause the battery to heat up during the final stages of its charge process [around 95%] due to the fact that to go the last 5% it will require higher resistance also in n^power. I suspect that in this great economy LG is cutting corners whatever place it can so there’s prolly very minimal quality control in power unit production. To those who think that they lose charge too quickly, that the battery gets too hot during charges, and possibly causing the phone to lock up: If you are using the stock battery, you may want to consider replacing it.
P.P.S.
Overall it is a hardware issue, in our opinion, that could be fixed with the use of the software, by rendering that extra line inactive for example. However, I would like to NOT compliment LG as a corporation and organization in general on their moral standing and responsibility that they carry to their customer base by doing completely nothing about this issue!
Thank You LG, I am no longer your customer.

HELP: Infuse overheating, Cant return to AT&T. Need advice???

I Baught the infuse on launch day off a friend of a friend of mine that was elgible for an upgrade. I gave him the money for the phone plus $100 for himself for doing it. The phone has been really hot the last few days. Yesterday it was at or around 100 Degrees F after i started using it (very light use). Last night when charging it took over 7 hours to fully charge. I turned screen brightness all the way down, have underclocked the processor to 800MHZ, what else can i do? Today the thing died on me in 3.5 hours and i didnt even use it... The screen was on for a total of 15 minutes. It was at about 105 degrees all day... i tried to contact the person who sold it to me to see if they could meet me at the store to try to return it for another unit, to make a long story short im unable to get ahold of them at all so im out of luck. What can i do? Is it possible to return to at&t without the reciept? I doubt it. I dont think the problem is the battery however, Ive take the battery out and its nice and cool, the hot area seems to be the metalic part covering the sim card right underneath the camera area thats hot. I can try to buy another battery but i dont think the issue is the battery. Im not sure what to do at this point. Any ideas on how i can cool the phone down? Or get a replacement unit?

It sounds like you have something running in the background that is forcing your processor to run at maximum speed (and voltage) all the time.
Try a menu->settings->factory data reset and dont install anything but updates, report back if it still gets hot.
Widget locker is being reported to cause issues fyi.

Might try contacting samsung. Maybe a battery problem. But sounds more like what previous poster said Runaway proceser

look in settings about phone for battery use. post results. it may be a bad app, it may be the radio needs to be reset. the radio's can put off as much as or more heat than the processor. if it says cell radio 50% then you just need to enter airplane mode and then turn airplane mode off.

*#*#4636#*#* and go into battery stats you can check all usage there lots of cool stuff

Thank you all so much for the responses, I have widgetlocker installed ... I will try that right now and report back. I've noticed too when I use setcpu after about an hour or so it would reset itself and I would have to go back in and reset it to whatever settings I had before

.......

What wall charger are you using? The correct specs wall charger for the phone shouldn't give you the choice menu for mass storage,... etc. It should just charge.
I found that if I used the wrong type of wall charger(even car charger) the battery would get very warm. Using the charger that came with the phone doesnt do this.
I think the phone seems to go into a usb mode but gets way more current than expected.

I would call samsung, they will honor their warranty, regardless of who purchased the device.

I had problem with htc inspire, which I have bought on Ebay and I obviously didnt have a receipt for it.
To make a long story short I took it to att and they have replaced it for me no questions asked.
I said I have bought it from a private party.
I'm hoping that all of the responses of guys here at forum helped You, but if not remember, to try Your last resource which is att warranty department.
But I would personally go to corporate store not call them.
When You buy anything warranty usually stays with the device not the owner.
I believe, there is stubborn application running in the background, have You tried taskiller?
Good Luck!

[Q] Camera flash + dark room + semi-charged battery = phone crash?

Came across this trying to take a late night picture in a bar, embarassing
Logged this with HTC support, they claim they cannot recreate so must be a faulty handset, seems like a software fault to me. Has anyone experienced this? Really don't want to return my handset....
Requires these conditions:
- dark environment, so that flash powers up to maximum
- 2G/gprs data connection (doesn't happen if on HSPDA, or wifi)
- battery not fully charged but charged enough so that camera flash option is available
Focus as best you can on an object, take a picture, phone will immediately shut down. Can recreate this every time in same conditions.
Weird.....

Had this happen to me once. Restarted , and ok ever since.

happened to me as well on the first day. battery was at 20% level at that time. recharged it overnight and tried again in the morning. everything was ok.
There are threads on other droids (Google Nexus S) for the same issue. So it cud be an Android bug.

Maybe the camera flash is causing a drop of voltage in the battery? O_O

I've had this serveral times.
Sometimes it only seems to use a single LED to flash.
When it uses dual sometimes it reboots the phone and then takes forever to load back up. Very strange.
Glad to see I'm not alone, Its a shame my first post is a bug!

[Q] Phone shuts down?

My sensation has a very bad habit and I would like to ask you guys if you know why it is happening..
My phone shuts down about once a day and then when it is turned back on the battery has dropped about 20 - 35 %.
I have taken few screen shoots of the battery level and they are attached with this thread.
Im not using any other ROMs or anything like that. I have taken about Juice Defender which I used for about 2 weeks.
I know three others Sensation users and they have never experienced something like this.
I have asked the sales people and the technical people and they have no idea and say that this is prob some app that I have put on but I havent put anything on it that can mess this up.
Any solutions ?????

wow, I've never seen any android phone do that, have you tried restoring to factory settings and then trying it out?
It could also be something HTC needs to fix on your particular phone, so I might contact them about it.

First I wanted to ask if someone knows the answer to this but if I dont get any answers I will do that and see what will happen.

Try uninstall juice defender. I had it last time for 3 days. Nothing it do unless harm my mobile data 3G connection connect & disconnect & battery life goes crazy up & down!!
Sent from my HTC Sensation Z710e using XDA App

juice defender is not for gingerbread devices

yeah i agree i think your best bet would be to uninstall any apps that have to do with the battery and see what that does.
if that doesnt work restore it

I have uninstalled everything and i did that before all the images that I attached above. I have over 10 pic like the once above.
Thanks for the advice I will wait a little bit longer before restoring it.

Does it a shut down or a restart?
if it shuts down, so that you must press the power button to turn it on again, it's the same problem i had, and maybe still having...
This problem became stronger and stronger (did shut down 4-5 times a day at the end, but always with "low" battery, <65%)
I've returned my device to HTC and they sent it back with no failures found
after 3 days the problem appeared again. Then i bought a new battery (a original one), since then phone didn't shut down except one time, but that could have been the new kernel i flashed . So I'm very confidently that this was the failure.

My phone shuts of and does not restart. So I guess it might be the same fault as you had.

Yes I would take it back and demand for a new one or you can contact HTC and they will charge oh about $250. But first contact tmo customer service first and see if they will replace it with a new one that way you won't have to pay $250 to htc . Your sensation shouldn't be rebooting on its own oh by the way make sure you demand a replacement they may try to get get out of it good luck

I had the same problem, I recalibrated the battery 3 times one after another (is it english? lol). The problem has improved but continued.
So I tried that [MOD] Battery jumping and accurate reading Fix 2.3.x.
Since I had the problem that 2 or 3 times in 2 weeks.
If I buy a new battery does it will fix it?
(Sorry for my bad english!)

I have the same problem too. I tried everything. I tried factory reset , flashing new roms, talking with htc but i cant fix this. It still randomly turns off. I think only new battery can solve this. One guy said that he buys new battery and 1 month passed still have no problem. So i ordered anker battery. I hope new battery solve this...

I have a theory here.
Difference kernel will give difference control and usage of current and voltage signal. Therefore if you are using wrong kernel for a long time, maybe it will damage the hw especially small small ic which very sensitive and cause it to malfuction which cause shutdown or restart and in the end burn etc.
Just my 2 cent and please ignore me if im wrong.
