Random Shut Down Issue - Theory: Let's compare apps

Some of us are having problems with our Captivate randomly shutting down. AT&T technical support thinks it could be apps that we've installed. Could they be right? My replacement device didn't start shutting down again after 3-4 days of owning it. By that time, I have already installed some favorite apps. Here's my list. Let's compare and figure this out. It's just a theory. Can't hurt.
<<<< OMG! While typing this new thread to turn on my phone so I can see the list of apps I have installed, MY PHONE TURNED OFF ON ME! WHAT THE...!!! >>> Anyway...
Apps installed:
-SMS Back Up and Restore
-Yahoo! Mail for Android
-Adobe Reader
-XDA-Developers
-Market History Manager
-Speedtest.net
-Google Maps

Mine never did it until I set advanced tag killer to harsh every half hour. I watered down the harshness a little bit and it hasn't shut off since

Theres a thread in the vibrant section that's about the same problem and it happens after 3 days could try there
Sent from my Nexus One using XDA App

Thanks. I just posted on an existing thread over there. I will do a hardware master reset later and observe again the next 3-4 days. Samsung gave me the directions. (Hold the volume up and down plus the power button, all 3 buttons for 15 seconds, etc.)

most are saying that its bad RAM/memory and exchanging the handset fixed all the problems

Is there a memtest type application for android? Bad memory would make sense, but so would a number of other theories.

Ur welcome hope it helps and u get it figured out

Yeah, that's their answer for all problems, big and small. I'm sure in some cases it's valid, but the reset is used more as a "what the hell' reply rather than a knowledge-based solution.

...which I agree to some point. Some users just end up loading crap on devices which screws things up (some of the apps mentioned above might be crap, or not, not sure, it's only a theory. Of course, a perfect device is a unit that can withstand ANY apps you feed to it. But we don't have THE perfect device (yet, or ever).
I will do the hardware master reset in a few minutes and not load anything for 3-4 days (but I will enter my Gmail account and let it sync with my Contacts, Calendar, and Email, but that's it...for now).

What steers me away from the app theory is that there have been several posts indicating that the random shutdowns have occurred with a stock device. No apps downloaded / installed.
I don't have an answer except to say that the master reset can't hurt. Realistically, though, if you go a few days without a shutdown don't sit back and smile like the Cheshire Cat. Sometimes the shutdowns occur weeks into ownership. I'm not being negative, just realistic.
I wish you well.

Agreed. Like I said, this is my second device and the shutdowns didn't start until 3-4 days after ownership on both devices. The reality (for me) is that the Captivate isn't so great after all after two devices already (sorry to say) but I'm not going to give up just yet. I have until the 31st to decide whether I will continue this 30-day early upgrade trial or take it back and continue to use my HTC Fuze and just let my contract expire (in October). If I take it back, come October, I will decide whether I will stay with AT&T and take on another (hopefully bug-free) Captivate, or move to Verizon and check out their Android phones -- HTC and Motorola devices!

I just did a hardware master reset. It isn't exactly a hardware master reset like the tech guy described it. He gave me the directions to "delete user data". It deleted the apps that I have downloaded from the Market, and other things. I don't know what else. However, when it booted up again, I noticed my settings and widgets are still there. My homescreen was still customized the way I had it. So, it's not a total master reset. The software Factory Reset isn't also a total (software) reset. I did that and found some folders left in my internal memory (not my external MicroSD) from the previous working session. Hmm..

my captivate started to shutdown about five days ago. it's been doing it once a day, always in the morning. i wonder if it has something to do with the power management. the phone is always charged overnight and the shutdowns always seem to happen about an hour or so after i unplug it from the charger.
the one day it didn't shut down, i noticed that the lock screen was unresponsive (ie i couldn't unlock the phone) and i ended up having to power down the phone anyway.

exactly how it happens on mine.

i'll see what happens over the rest of the week and then try the master reset. if it still happens, i'm going to return this for another one. unfortunately, i've had it for over 30 days.

Even after 30 days, you will still be able to return it (maybe to Samsung) for repair or a replacement. Good luck.

Mine has shut down twice, and I've only had it for 12 days. As you described, it happened both times in the morning, following a recharge.
I had to remove and replace the battery to get it to turn back on, is that the same thing that happened to you? I mean to say, did you have to remove and replace the battery to get it to work again?

The two Captivates I've owned (and returned due to a combination of GPS and Random Shut Downs) have shut down on me even in the middle of the day (not only in the morning after recharging for the night). It shut down on me while getting my afternoon coffee. I was showing the phone to the Barista, set the phone down on the counter to pay, picked it up, walked back to my office and just when I'm about to wake it up, it does the bootup. It also shut down on me at night while walking in the dark. I noticed my pocket lit up. I pulled out my phone and I saw the Shut Down screen as if you had pressed and held the power button (but nothing else was in my pocket that could have pressed the button!).
Random, I tell ya. Random.

no, i just turned it back on using the power button.

I just wanted to chime in to say that I am having the same problem. Random shutdowns, not necessarily related to charging. Often they are in the morning however. For me it has been happening a few times a day. Likewise, it seems to have not happened at first, but began a few days ago (I have owned the phone about 2 weeks.)
Are you guys rooted? I have tried unrooting to see if that matters. I don't know why it would, but perhaps...

[Q] Nexus S goes into some sort of fault state

My two months old Nexus S started to behave in a way that renders it pretty much useless - Freezing / Locked U
Freeze/Delay Between Menu and basically the phone is dead.
Very often when the screen is off, pressing power button powers up the screen with the screen lock, but the phone is not responsive so the screen just goes off again as it is impossible to slide to unlock it.
On top of that, leaving the phone with the screen off for a half an hour or so brings up some sort of warning sign and a small android (can see the screen shot here: http://yfrog.com/h3apmgqj) and the phone is effectively dead. The only thing to do in any of the two cases is remove and reinsert the battery, but that is no solution to anything. All this is while the battery is fully charged.
Did anyone experienced this before? resetting phone does not help.
Here is more info on this topic: http://www.google.com/support/forum/p/Google+Mobile/label?lid=4e31a500f89fe575&hl=en

Are you using a custom recovery/ROM? That icon you posted isn't the stock image

Hi, no I do not - the image is actually from different phone but it looks exactly as it did on my Nexus S (little green guy with an exclamation mark). I never rooted my phone or done any custom mods to its system.
I actually sent it to Samsung and they are claiming that they found no problem, so they re-flushed the phone and are sending it back. I am seriously angry at samsung. It is arriving on the 11th so I'll let you know if that helped but I doubt it.
I believe this might be a faulty memory because I often received notification that the internal storage was unavailable or something of that nature as well, right before the problem would occur. Are the any tests I could perform for memory / storage?

just try to flash it back to stock
then do wipe data and wipe cache
see if that gets it back on its feet

Hey,
thank you, I thank that means I would have to root it first ehhh
Samsung told me they've done just that (flashed phone) so I am seriously hoping that my phone will work when it arrives on the 11th.
thanks!

Samsung supposedly is looking into this problem, please see link below:
http://www.google.com/support/forum...ad?fid=44db6d8e31129d4c00049e3b2a6db4d1&hl=en

Update:
I just received my phone from Samsung repair and of course, the phone is NOT fixed. On the side note, they also sent back my note that explains the problem meaning it was ignored completely.
I will be contacting @SamsungServic and calling but at this point I am not sure that they can fix the phone other then replace it.
Also,
I've spoken to Samsung and chat online and - yes they nice and throw back lots of promises and niceness back but they are NOT doing anything about it, for now at least.

I copy and paste the best answer on the google support topic to here:
I've been keeping a notebook to document my debugging of this problem. No app in particular is responsible, in my opinion. I have observed the phone lock up after a Factory Data Reset + USB wipe, and with no accounts configured. In fact, I have had it freeze after following this procedure:
1. Factory Data Reset + USB erase from Settings menu
2. Phone reboots.
3. Go through initial setup screens, skip account setup.
4. Power down phone.
5. Remove battery.
6. Remove SIM card.
7. Replace battery.
8. Power up phone.
9. Let phone sit for 15 minutes or more.
10. Phone freezes.
This is about as close to bare bones as I can get with this device.
I have also documented at least four freeze modes:
1. Phone is completely dark (both display and buttons). No combination of power button or other buttons can bring phone back. Battery removal required.
2. Phone display is dark, but the four "hard key" buttons are illuminated. No combination of power button or other buttons can bring phone back. Battery removal required.
3. Phone displays only a green android by a warning exclamation sign. Holding power button down, then volume up, then release volume up, will bring up the Android system recovery screen, from which phone can be rebooted.
4. Phone is frozen at the unlock screen. Sometimes this freeze occurs while swiping the unlock icon. No combination of power button or other buttons can bring phone back. Battery removal required.
I have observed the phone going from normal standby state (display and buttons dark) to state 2, and at other times to state 3, while it was sitting on my desk by the keyboard.
I'm just about ready to send it to Samsung. I just wanted to verify that the problem would be reproducible after a factory reset and without the SIM card.
I think it may be a hardware problem. It's also possible that part of the Android kernel or some device driver on my device has become corrupt. Unfortunately I can't reset the OS.

I did a factory reset from the stock recovery, too. Doesn't help either.
My phone arrived on Friday Samsung mobile repair in Texas. And like they did to ohter Nexus S devices from other users they will do the following to mine:
Reflashing the phone -> doing some functional tests ...
... and this is the crazy thing about it. The error we have is just appearing when the phone is in standby and because of this the phone passes the functional tests Samsung is doing at the end of the service. Phone goes back to user. A defective phone.
Some guy managed to keep the phone alive by setting the display turning off after 30mins. He is charging it twice a day
I got a reply from @SamsungSupport on twitter:
Thank you Fabian for again reaching out to us. We are aware of this issue as some of us have your same phone.
An evaluation is already being conducted to determine the fix. We don't have a timeframe of the resolution.
But understand it will be pushed to phones. We will advise once we have a timeframe.

The support team is friendly and to me it feels like they try to do anything they could.
Funny: One guy got a replacement device. But then no one other. Just reflash...
I think they will do something but on the other hand I'm worried that they will do nothing. But time will tell....
Maybe it would help us if Google will be aware of the problem, too. Ok maybe they allready know it, but I don't know that.
So if some of you here do have some connections... please do us a favor and forward this topic or the link to the google support topic. Feel free to forward this topic to any website you think it would write a news about it. Maybe Google will throw a eye on it. My phone is 8 weeks old and yeah this so anoying. And of course all my friends who are iHippster are trolling me like hell.
It don't want to flame or blame Samsung\Google for this.But our phones are in warranty. The error hits only a few devices and so they should replace it. My 50cent about it... this is not a Google expierence they talked about...

I also had the same problem and sent my phone into Samsung. They only re flashed it, which didn't fix the problem. I immediately called Samsung to inform them that the issue was not fixed and they just told me to send it back for "double checking." Do you think it is better to send it back in or just wait for fix to emerge?

I will be sending it back and demand replacing the phone, also making sure they just don't re-flash again. I guess anything but re-flashing could work.
Remember that I've mailed my phone with one page letter explaining the problem. Their response was flashing the phone and sending it back - with my letter.
Here is note from the support team:
----------------------------------------
Original Problem:
Technical Inquiry
Phone Freezing / Locked U
Freeze/Delay Between Menu
Problem found:
NO TROUBLE FOUND
SW,PRL,OTSL RESET
Solution:
Passed All Functional Testing
--------------------------------------
@Samsungservice did not even acknowledge it officially that this is a problem.

Yeah i wrote a letter too explaining the issue and how to recreate it (the first time). They told me that it passed their quality assurance inspection after re-flashing it, which must be very poor because my phone shut off again 15 minutes after receiving it. Just dropped it back off at UPS today. Can they replace the phone because of this issue? I know one person had success, but it doesn't seem anyone else has.

Nexus S faulty
Samsung may not be able to reproduce it after reflashing; as this issue does not seem to occur when connected to a PC/computer via USB. Their automated testing could be over USB.
Looks like more and more people are facing this issue as the day goes by.
Search for "Nexus S fault state" on google and you'll find the google support forum thread discussing it

Guys,
Did anyone have tried to flash a custom rom to see if this will solve the problem ?
cheers !

No, but this problem is not ROM related.

I figured that was why they couldn't recreate the shutdown. Made sure they knew that it has to be unplugged. Mine always shuts off within 10-15 minutes if untouched.

I have same problem.Only remove battery helps. I have been having nexus s for 2 and half months and this problem just came last week. I don't know how to solve it. I tried reflash firmware but didn't help.

welcome to the club. you have to send it to USA to get it serviced (make a extreme detailed problem description and make sure the support worker writes it down 1:1 into their ticket system). they provide a 2day ups shippment label, BUT only to locations in USA.
I can recommend FedEx. They helped me a lot with this duty stuff for shipping to USA. That's not so easy . I paid €50 to get it shipped to a friend of mine in USA.
You have to send only the foreparts of the device. No battery and back panel, no charger and so on. But they will give you all informations at the end of the service request.
or: wait for a hotfix. which maybe never will come.

Update:
I just mailed my phone again... they told me they do not replace phones (not sure what that means yet). The Rep was arguing that if I want the phone replaced then I need to talk to T-Mobile - it does not make any sense.
Anyway, I explained the problem as much as I could and did not mail any notes this time as they obviously do not care for it. But I made sure he included every detail in his notes.
I am very skeptical but still hoping....
Also,
About the part when the phone does not freeze when plugged in or charging. I had my Nexus S charging overnight and it was frozen in the morning.

Update:
Also, I've contacted @SamsungServic via Twitter and asked if their team recognized it as a problem, but I've got no response.
On the other hand if you report the problem to them, they will respond that they will look into it - which means nothing, but if enough people asks the same question them they will have to.
-thanks

I've got some sort of responce via Twitter from @SamsungService, here is what they wrote back:
@SamsungService

@Keinam
Does this mean we should stop sending our phones back for repair and just wait for your OTA update? If it happens?
@SamsungService
Many issues can be resolved with warranty service. Regarding the issue you've referred to,It is my understanding that a fix if being worked on which would be sent out OTA. ^Mary

[Q] Last hope: Desire S stuck in bootloader S-on

Hello,
My Desire S froze when updating Skype 2 weeks ago.
Removed battery. Phone stuck on HTC logo.
Went to bootloader for hard reset. When hard rest chosen phone freezes.
Went to recovery, phone starts recovery. Black screen, green icon. Then goes dark. Starts to vibrate 6-7 times. Then remains off. Battery out, battery in. Back to HTC logo again.
Laptop recognized phone when plugged in with fastboot mode. Under device manager (win 7) "HTC phone".
I bought the phone in Thailand, but am now in Philippines where there is no HTC repair center.
I managed to find RUU_Saga_HTC_Thailand_1.35.1113.2_Radio_20.28d.30.0805U_3805.04.02.01_M_release_183327_signed
Which matches my phone. However when trying to install the rom, the above app freezes on "restarting bootloader". I've left it there for over an hour.
I've tried ADB, but it's not picking up the phone.
I'm guessing either of the above can't load, as the phone is S-on.
But I cannot go S-off as I can't get the phone to boot, or any of the above software to find the phone. Again, windows is picking up that there's a HTC phone plugged in.
I've tried everything I know, and am at my wits end into thinking the phone is finished.
Can anyone help with something I may have overlooked, or have a suggestion to bring this back to life?
Thanks

It's most probably a hardware problem. There's a high chance that your phone's emmc chip is fried when u remove the battery. it's common in htc due to the phone design. My phone encountered same thing 2 weeks ago. sent for repair and they change the mainboard. I was lucky they ignored that my phone was S-on(warranty voided)

I was thinking hardware last week after everything was failing. But as it was still booting to fastloader, and being picked up via usb was holding out hope it might just be the s-on preventing me from putting on a new rom. And not a mainboard gone.
Flying back to Thailand for the warranty would cost the same as buying a new phone ...
If taking a battery out when a phone is frozen fries a mainboard on HTC ... I doubt I will buy one again.
Looking at Galaxy 2. But also having doubts due to wifi reports and overheating screen. Can't afford another dud smartphone.
If anyone's got anything else to get this thing up to see if the mainboard is indeed dead, or it's something else, do make a suggestion please!

I have same problem like this before and it's really pain in the a#$. Also, there is one HTC service center here in the Philippines, check it out on HTC site.

Yes, I've been in touch with HTC repair center in Manila via phone and email. I've been waiting for reply for over one week now!
I'm not in Manila, which would mean using fedex to send it up to them. Then bank transfer to pay for repair and shipping back.
If it is the Motherboard that's gone, all the above will probably cost more than a new phone
But I won't know until HTC Manila actually bother to reply!?!

so what was the Problem is it becoz of Skype?

no,this problem happens if you pull the battery out when installing apps
the emmc chip is probably dead,if so you need to send it for warranty or replace the emmc chip yourself

Well unfortunately, when updating the skype app, the phone froze. As in no buttons working, phone getting hot etc.
What else is there to do but take the battery out?
Either way, to have a "premium" phone like the HTC Desire S, burn out a chip, or indeed have a popular app causing it to brick etc is simply not good enough.
More over the support center refusing to reply back.
It simply means they've lost another customer.
The phone, when working, was wonderful. Looking at the Galaxy S 2 today, by all accounts a "better" phone, and it was sad. As, for me, the HTC Desire S was much more preferable.
Except of course for it's 6 week lifespan ... bad customer care etc

Just to bad that you did not bought it here. My phone died two months ago (used it only for a month), sent it to the store and they've sent it to service center (in Manila). Had to wait for a month for them to fix it. Motherboard issues I think. Good thing I still have warranty.

but mine has been working for 3months without any problem,& the customer support here is good
if you dont mind voiding the warranty you can buy a eMMC & replace it yourself
if you do so you wont get this problem again
refer this thread for more info

There is software "hard" reset option. Instead of pulling the battery out, press all hardware buttons together (vol up, vol down, power button) and phone will reboot. I said this many times before in many topics: never pull out your battery when the phone is on. I learned it the hard way.

Thanks kartkk. I wouldn't know where to begin with the physical replacement of the eMMC chip. Not even sure I can buy one around here.
I might call HTC Thailand and ask if I can send it to them via DHL or the like.

maybe you should ask HTC to write that in big red writing on the back of their batteries as they start to reach burn your finger stage when the phone freezes.
Or maybe copy Nokia's hardware which is near on indestructible.
Quite simply, I am not a phone tech person. I'm a simple end user.
I've not had a problem taking a battery out of other phones.
Again, if taking a battery out of a phone kills it when it freezes, then quite simply the phone is not good enough. Or, if it is likely to. Then, again, in big writing for simple folk like me, big red writing on the battery saying
"don't take this out, even if it starts to feel like it's going to melt"

BTW if anyone can point me to a step-by-step on how to determine if the eMMC chip is fried or not, I would appreciate it.
I read the above link. But don't know how to get to that stage!

Apologies I see he was connecting via adb-shell. I've tried connecting via adb and it's not seeing the phone....
Which I think is half the problem.

try searching on ebay for sandisk mmc (or any other brand just dont get the same one used on the DS)
its always dangerous to pull the power from any device which works like a pc even in a pc pulling the power out while the device is on can harm the hardware &/or software i know many people who damaged their pc from pulling the plug while its on

Best to my knowledge it was an emmc chip that was recommended to be replaced. Not an MMC.
While removing "power" abruptly from any electronic device is not recommend, one is sometimes left with no choice. Complete device freeze, no buttons working etc.
There is also a destine difference between a PC and a mobile phone. Though, it must be said from my point of view: today's Android phones, are very reminiscent of old windows 95/98 OS's in terms of stability and hardware issues.

[Q] HTC Sensation Always powers off

Hi
just want to ask if anybody have encountered my problem with htc sensation.

i had it fixed on the service center but still the problem persist.
i ask what action did they do, according to them they just re-flash it.
after a week the problem re-surfaces, would like to ask about your opinion on how to fix it. thanks in advance

are you running custom roms?

Got the same problem and i know one other Person who does. Problem stopped appearing for some time and now its back worse than ever with random shutdowns even during calls. Running Stock HTC ROM not rooted or anything. Found some clues on the internet that it might be caused by a SW Update that came from HTC. Nothing for sure though. All i know is that i am seriously looking for another device at the moment. HTC and Android devices are annoying me more and more lately. No Official Updates (or they take 6 months), Compatibility Issues... The list grows longer every day. I used to love Android Phones, especially the HTC Ones but they appear to be stuck.

you have just been unlucky...i'm running custom roms and sometimes i get random reboot but now it is all ok!

send it back!
I had exactly this problem, phone kept turning off at random. Mine was totally stock, first time I sent it back they re-flashed but it started turning off again after about 2 weeks. I sent it back again, they changed the motherboard and its been working fine since then (touch wood!).

Also had random shutdowns. Got a new battery and the problem was gone. But now 4 months in on the new battery same thing starts to happen again. Beginning to thinks there's something wrong with the power management.

there is actually an issue on the power management, which is fixed with the ics update. If you can wait , you'll get an update from htc
if you cant, go ahead and flash a custom ics rom

I had the same problem before I bought a new battery and i hope it wont come back when the battery gets older. The problem was with 2G networks. If you turn the mobile network to WCDMA (3/4G) only in the settings, the phone shouldn't shut down. I hope the ICS update completely solves this

I had the same problem as well. I flashed ICS and it would still shut off. I noticed it wouldn't ever shut off if it was just sitting on my desk except one time it shut off when on my desk and someone called and my phone vibrated. Turns out the battery connection wasn't tight enough and when moved around, it would lose power. I folded a small piece of paper to make the battery fit tighter and it hasn't shut off since (about a month)

Hi all, I have gone through this problem... I have done all troubleshootings S-off S-On different roms new sim car everything even flashed by service station not helped...on solution for random shut down for me was changing motherboard and after they changed my motherboard I haven't faced single issue... get board changed.
Issues
1) random shutdown
2)while calling some shuts down
3)If it shuts down it will again shut down imd. on 2-3 attempts then start properly.
4) when screen is off and u push power button u find phone down
5) Random shut down some time imd or it will not happen for for next 8-9 hrs.
Get mother board changed.

I was experecing the same issue.
Random reboots or random shut down !
Never when my phone is charging, only when it is on battery.
But I'm trying something, the auto brigthness ! I desactivate auto brigthness, for the moment no ramdon reboots or shut down anymore, was testing 2 days now ! Perhaps try this solution !

Try to remove micro sd card,test the phone and if it does work ok change the card,that was my solution.

3 users in my office are seeing this
3 sensation users in my office are seeing this too, the UE "powers up" when you attempt to wake the screen i'm taking logcat but i'm yet to determine if the phone is powering off at some time when the screen is off or when you attempt to wake it.
i am seeing the battery stats are all over the place after it boots up.
this does not happen when it is being charged.
the logcat from my phone sometimes say a process has crashed (latest 03-06 17:06:18.995 I/ActivityManager( 321): Process com.htc.ereader.drmengine (pid 2742) has died.) but not in the majority of my logs they just appear to stop,
if anyone is proficient at logcat analysis i can share a log taken of a failure.
the 3 users in my office have:
1X S off and ICS ARHD
1X S off and ICS (trips)
1X S off GB unbranded
any help would be gratefully received
**EDIT**
having just pressed the power button to wake the screen(19:00) the phone booted again i was able to check the logcat log file and it stopped logging at 18:02 so it appears to be crashing when going into sleep or when in sleep mode rather than when the wake command is issued
also: http://forum.xda-developers.com/showthread.php?t=1500966 looks like the same issue.

Same problem on HTC Sensation with ICS
Hi,
Sorry to crush your hopes for ICS solving the problem but I'm running Android Revolution 6.5.0, a custom ICS ROM, on my Sensation and I'm having the same problem. Never had it with the stock ROM, though.
Also, it's never happened when plugged-in or when the battery is full. Seems to me that it shuts down more frequently when the battery level gets lower.
Anyone experience it the same way?
Anyone solved the problem by replacing the battery?
Cheers,
Stefan

Hi
any news about this?. Is this problem caused by a hardware failure finally?
Thank you!.

Hi,
I fixed my problem (random shutting down) setting my network mode to 3g only.

Well I got my battery replaced. Worked fine for about 3 months. Now the issue is back. I think it has something to do with the power management on the phone wearing down the battery. When I plug in my charger I feel electricity in the back cover and a humming sound in my headphones. Somethings wrong with the hardware. Going to send my phone in now

I get a weird humming feeling too, like a vibration as you run your finger over the back. Whats also weird is that if im holding the phone and then someone runs their finger on my hand, they also feel the static/vibration feeling. However as soon as I put the phone down the vibration feeling goes. Its so weird, if I send the phone off I'll be phoneless for weeks!

Very simple solution
Hi guys,
Most of us (myself included) are sometimes blinded by our knowledge of custom roms to not try the most obvious fix for this finally very simple issue...
I have a park of about 20 HTC sensation on my company and had the problem on several of them (mine is running a CM9 nightly , but all the others are stock). Had the motherboard/battery replaced on some of them, tried many settings (and on my phone, different roms) but it only offered a temporary and random improvement. I found the solution on a forum and I'm ashamed I never found it earlyer as it's so simple:
Remove your back cover and place a spacer (the thickness of one or two visit cards) between the top side (right part, just opposite to the connector) border of the battery and the chassis. This will ensure that the battery presses a bit harder on the connector. Without the spacer, you may notice that the battery is in a slightly skewed position, not totally parallel with the compartiment and therefore not pressing hard enough on the connector. We never had an unexpected shutdown since then !!!

[Q] Phone Suddenly hanged and now donesnt work properly

Hello Guys,
Tuesday night i kept my phone on charging, next morning the phone didnt repond on the wake button, tried several times no help, removed the battery and restarted the device but it took it around 30 minutes to boot up, but the touch screen didnt worked at all, i tried to format the phone via bootloader (after pulling the battery)on first try no result same issue..non working touch screen, after formatting again it started workign smoothy, but i am again facing the same issue today, phone wont start up, and same issue with non working touch scrren.... cant even pickup an calls.... Need you help on it.. I m on Stock rom 2.3.5 with Sense 3.0 overlay non rooted.. and help or i need to go to gallery to resolve the issue

Hi Zeus,
Firstly - Never, ever pull the battery!!!
There - over and done with. Pulling the battery runs a high risk of causing permanent damage to the eMMC chip. You should (I have never locked up my phone so badly that this doesn't work) hold down the Power, Vol+ and Vol- buttons until the phone shuts down on its own.
You say your phone is no-rooted? I guess that means that you have not run any kind of mod on it, obtained S-OFF or anything else and the phone is, basically, as you bought it? If so then I would recommend that you simply go via HTC or your service provider to obtain a replacement.
If you have not felt the need before now to unock/root your phone then now is not really the ideal time to start doing so if you have a warranty still.

If you are in Mumbai (as on ur profile) , You can visit the HTC Support Centre @ Borivali (Thakkar Mall, near Borivali Station) - http://www.htc.com/in/help/service-center/
Please Note : They will most probably repair the phone (I don't think they replace the phones here in India after the initial 15 days period in which u can claim the Dead on Arrival policy).

Thanks for all the Suggestions,
Have read all the issues regarding emmc chip being fried on Desire S, but being out of town for some day, didnt had any choice but to try, however i let the battery drain completely yest.. recharged the phone to full and then booted again.. and its working fine as of now (didnt worked earlier).. without any issues from last 5 hrs.. lets see how it holds, havent yet installed any of apps yet.. guess will wait for another day or two to see the software fails again to hold.
went borivali, but its not yet started (confirmed with customer care of HTC) still being completed..
but yes.. will visit the Dadar branch if any issue arrises afterwards

Glad to hear its working fine as of now.
Btw , regarding the Borivali Service Centre . . I have been there last month & it is well up & running !

Been there on Friday evening at around 6 but it was closed....then I inquired on customer care which told me its non functional as of now... Will check tomm....
The phones working f9 now...no issues in past 2 days...hope it holds

Guys, I have seen this kind of problem with one of my colleagues phone (Not Desire S but Wildfire S). The reason was (assumed) pretty weird though, it was because of some electrical problem. Whenever he would charge his phone at home - it would start having this kind of problem, but when he charged it at office or through his PC - the problem would vanish!
Although I am not sure if yours is the same case.... but then could be..
Another thing: I got my phone's mobo replace free of cost from HTC (Salora) when it was under warranty even though it was S-Off, Rooted - so I think HTC is a bit lenient in India

The issue it seems has vanished, no issues as of now..no hangups or freezes and yes....both the time the issue arised when the phone was in charging.
