[Q] Fully crashed at random? (acting like turned off) has it happend to you?

Very strange thing happened to me today, went to wake my phone up from lock screen but I pressed the power button and nothing, no wake! I knew I had lots of battery left, but thought maybe it died for some reason, plugged in charger, no response still could not turn on, even holding the button down did no change, nor opening keyboard.
I then removed the battery and re-inserted, booted up and its working fine again
What happened?!

It just happens This happens to my Desire Z every month or so, no matter what rom I use. Recently I changed the radio the latest release, but it won't help I suppose... we'll see.
It seems nobody knows why this happens, many questions are scattered around the the forum about this hang and no answer

sorry for my english
gps make this problem (+ google maps + all google maps based programs)
just turn gps switch off
when you have to use gps, turn it on, use it, turn it off, reboot
and DZ should work fine
http://www.google.com/support/forum/p/Google+Mobile/thread?tid=69305f1c1e5f8c31&hl=en

Not sure what causes this, but it happens occasionally to me too. Maybe once a month or so... Happened earlier today. Hadn't used Google Maps nor do I have any apps that use GPS to track my location.

Happens to me all the time, in average about once every 1-2 days. I put my phone on my desk with screen off, and an hour later it does not respond to the on/off button at all. Sometimes it will reboot when I press the button for over 15 seconds, but most of the time I have to pull the battery, which is a drag since I have a silicone phone protector. I have also noticed that every once in a while, the battery will be fully discharged when it does this. This morning my phone was at 80% battery power, I used it for a minute to check mail, then put it down. 15 Minutes later it was dead, and when I pulled the battery, all I got was a little screen saying 'Please connect charger immediately'. Kinda scary.
I've seen lots of posts about this too on androidforums.com and on MoDaCo. My wife has a Samsung Galaxy Ace on Android 2.2.4 and she has the exact same problem. I haven't found a solution yet, but it seems to be software-related (since it's not limited to Desire-Z), and more specifically Android-related (as it also happened on stock phones without any third-party apps installed). I upgraded to Android 2.3.3 last week and that did not solve it.
Other suspicions I found on other fora:
Correlation between 'phone sleep' and 'WiFi going to sleep' (some people report they benefit from keeping WiFi always off unless they really need it, some people report success keeping WiFi always on; for others - like me - it does nothing or made it worse)
Correlation between phone and SD card (phone does not work properly if the SD card is not the original one, or has not been formatted on the phone)
Correlation between WiFi and SD card (people report reformatting the SD card on their device helped, after they've turned WiFi off)
I have heard people that have had their phone replaced 7 times and all 8 phones did it, some others got the problem solved with one replacement, so it seems not all devices do it.
Check out this thread: http://androidforums.com/samsung-galaxy-ace/312084-randomly-turning-off.html
A personal observation of mine - and maybe hardware gurus can comment on it - involves the micro-USB connector. Not only is it a pain to connect (compared to mini-USB), but I have noticed that it very easily 'jitters' if there is a slight bend in the cable or if you move the phone while it's connected. The plug will then sit slightly crooked in the connector and the phone will stop charging. And actually, I'm pretty sure that the first time it 'died' on me was when this happened. Would it be possible that this triggers the event? And that the micro-USB is the common cause?

I wonder what radio all these dying phones were running? I had 12.28b.60.140e_26.03.02.26 , now I'm running latest radio, but only a few months will tell if that helped or not...

Update: it's been about a week now since I've disabled GPS and I haven't had a single SOD since! Seems that at least in my case GPS was the culprit, like others on here already suggested. Can anyone else confirm?

my GPS on 24 hours already is ok... but Wifi is a no... i come out of the house this morning... it hangs again... totally black screen and it boot up again when i press the power button so my story tells me never on the wifi when you do not needs it... maybe i'll sent it to HTC SC for checking when i get a new phone... i duno whether i can survive 3~5 working days without it...

try this for a week or too:
have gps allways off when you dont use it.
when you have to use gps, turn it on, then after use turn it off and reboot the phone
and notice how many times you phone hangs in this too weeks

Hello,
i have the same issue with my Desire Z. Many people say its GPS related, i think so, too.
I never hat issues with GPS while navigate. But because the issue is probably caused bei GPS, i have a idea.
I use the wipe efs-data using for GPS from here: http://forum.xda-developers.com/showthread.php?t=1028405
I never had freezes since this. Maybe it helps everyone. Please try and give feedback. Thanks.

Yesterday my Desire Z did exactly that. For the first time. First I thought the battery would be dead, but connection it to the charger didn't even make the orange LED turn on. So only taking out the battery and re-inserting it brought my phone back to life.
I had WiFi turned ON and GPS NOT turned OFF (though no Maps or anything running, so there was no satellite icon in the status bar the last time I had used it).
I will keep watching it, if GPS OFF or an EFS-WIPE might help. But right now it has crashed the first time in about two weeks, so it will be hard for me to tell any improvement before at least a month has passed. ;-)
Tronar
Addendum: after finishing this post, I went downstairs to pick up my phone. And it was dead again! Seems to be happening more often at the moment, than I thought. So I'm going to do an EFS-WIPE now.

google maps is running still in background (also when You try to kill it with taskkiller it will stand up) and use (or try to use) gps for example for location for weather forecast. it can happen that the gps icon cam in notifications bar only a few seconds so You can't see it
it is possible that another apk use (or try to use) gps to get Your location, geotagging photos or so.
just have always gps off (when you haven't to use it and reboot after using) it helps

Bad News, wiping efs-data did not resolve the SOD . Yesterday it happens again.

My gf has the Desire Z and loves the phone - cept for this random issue of her phone freezing on standby. After a bit of screwing around I found out it is definitely related to the GPS module. Whether it's a hardware or memory leak it doesn't matter to her. You can crash her phone anytime by simply using the GPS and any software (she likes google maps / navigation) when she's done whether she turns off the gps or not, makes no difference - within a few hours at the most - it'll crash every time.
The short version, after using your GPS you'll have to restart your phone and you'll never have it crash again.

[Q] Device becomes unresponsive after several minutes of use.

Hello,
I have an HTC Desire HD running Android 2.3.3. The device isn't rooted and I've never rooted it before.
I've checked on this site, and I've scoured Google all day but I haven't managed to find anything that matches my problem specifically, as explained below.
In the last couple of days I have been having a bizarre problem where after several minutes of normal use the phone becomes completely unresponsive or very laggy (to the point where it is unusable). This occurs whether I am using apps or simply looking at the home-screen.
The only thing that's responsive is the screen lock button, this works as normal. However when I then try to unlock the screen, the phone is still unresponsive and I'm unable to unlock it.
The only fix I've found (if you can call it a fix) is to leave the phone alone for a several minutes. If I do this I can once again unlock the screen as normal and continue using the phone, however after a few minutes of use it locks up again! This has been happening since last night now and I've found no way to break this cycle.
I did a hard reset to see if this solved the problem but it had no effect. The phone will boot as normal, and after a few minutes of normal use it will become unresponsive again.
I've also booted my phone without the SD card in just in case anything on this was causing the problem, still no improvement.
Has anyone else experienced a similar issue who could provide some insight as to what might be causing this issue? Any help you can provide would be greatly appreciated.
At first I thought this might have been a software issue, but as it persisted after the reset I'm beginning to think this might not be the case.
Thanks,
KaRsKiN

The problem is coming from the magnetometer. I have the same issue, please check this thread: http://forum.xda-developers.com/showthread.php?t=1394264
The only workaround I found is to disable screen rotation and do a couple of restarts (not switch off). Of course, no compass in the end, but at least I can use the phone.

It is possible that your battery could be failing. See if att has one they will let you exchange.
If its not the battery then it could be a hardware issue. Just send it in for warranty if that is the case. You should still be covered as the phone is not yet a year old.

How should this be connected to the battery...?
Anyway, I think that it is a software issue rather than a hardware one. Maybe something is running in the background, using 100% of the cpu. You could try CPUNotify for realtime cpu monitoring.
If that doesn't work, you should try the magnetometer way. Maybe it's a new issue. Never heard about it though
I do what i want, because I can.

I'm not going to explain in detail about the relationship of voltages and CPU usage. The battery being bad can and has caused these exact issues. Just like if a power supply is failing it can cause a blue screen in windows. In android the phone rebooting itself or freezing is the equivalent to a blue screen. Since they have never rooted and are on a stock rom there is nothing except a hardware problem that would cause this. If the battery is not the culprit then one of the many components in the phone can cause freezes and reboots if it is failing. Android os does not allow a single task to take over the CPU. This is not a windows os. So like I said, just use your warranty and get it fixed. Stock phones should not be presenting this behavior, you would have to root it to cause these kind of problems.

Thanks for your help! My dad has the same device as me so I'll try swapping out the battery to see if this solves the problem. If not I'll try calling HTC to arrange a repair.

Any news? Was it the battery issue?

man, that's already the 3rd if not 4th thread abut this issue, one being opened by myself...
glad that I'm not the only one...
at beginning I thought it'd be a faulty/bent usb connector, as experienced by others, but since I am redaing of others with the same problem after upgrading, then it cannot be...
have you install;ed the OTA or started from cratch? have you cleaned dalvik cache? (I did with no avail) do you see a pattern in your wakeups? is it every x minutes? is it at random?
as regards me, it happens also when wifi and 3g and sync is off (but 2g on, that is I can only receive calls), so it cannot be anything related to signals...
I have installed BetterBatteryStats and will be sending a couple of resports to the developer trying to see if he can understand what is going on and what wakes up the phone...

I did a completely clean install... Wipe data and cache... Installed the OTA rom available on developers section.
Do tell me if you are able to find a solution.

I am in the same boat, Thegios.
No Wechat... No Daydream.
I have noticed my screen waking about every 10-15 minutes. It only happens when connected to my Wifi. My N7 does not wake at all. I have wiped the Cache and noticed my "Android System" hogging my battery stats.
I am trying to search what Apps I have settings for something like "sync only on wifi"... from there I should be able to find what is turning the screen on. I have BetterBattery Stats installed, and am trying to dig a little deeper there as well.

cant b wifi, , mine wakes up also when wifi is off and 3g is off and sync is off
I have tried with bbs as well but found notjing wrong

i've read all the reports of bugs, and the people with issues seem to have flashed the stock AOSP rom.. i dont have any of the issues described and the way i installed 4.2 was first flashing the takju 4.1.2 with nexus toolkit and then i got the 4.2 OTA from "about phone"->update.. oh and i have daydream activated.

For those of you with high android system usage, are you downloading music from Google pay music for offline usage? I did and I got this sudden increase. this has never happened to my phone before. Maybe Google play music needs update?

Your problem may have been resolved but wechat and daydream is not the solution to this as many of us aren't using either and still having this issue. I think I'm going back to bone stock 4.1.2 and going to let the OTA upgrade me to 4.2 and see what happens.
wechat is NOT the solution people, as the Google Code page suggest this is a sync issue that could be caused by a number of apps.

Strange behaviour you think only your Gnex has

I browse xda alot and stumbled up on many weird issues.
Maybe this thread could be an advise-thread like "don't use your Gnex with a Netgear N Wifi AP"
If there is no interest in this thread, just let it die
This is not a thread related to a specific ROM. More for flashaholic people like me who encounter little issues that occur on many different ROMs.
I will list my issues so you get an idea why I started this thread:
- If I connect my Gnex to the charger and use it, almost every time PIE will break and I cant navigate anymore (AOSP-PIE) - I have to reboot my phone.
- If I connect my Gnex to my schools WiFi (CISCO Hardware) I have constant data-download activity and my battery drains in no time
- Sometimes if I connect my Gnex to the charger it behaves like it gets plugged in and out very frequently
- At home, connected to my WiFi (Netgear Router) I have to constantly wake my Gnex to receive new messages (Whatsapp, Mail, etc.)
Maybe we can help each other with tips?
- cheers

I have not faced any of these issues. Been changing ROMs ever since the day I bought the phone (A year and a half back).
That charging issue alone cropped up once. But I was able to fix it by pushing the pin in the charging port up by a bit using a safety pin

1. My volume down is busted. Pressing it on normal mode, nothing happens. In Safe Mode, it works though I have to press real hard. Due to this, cant do screenshots anymore.
2. I can connect this gnex to my computer fine but the phone does not detect the charge.

well, that's interesting! I'm planning a replacement because my phone is two years old and so is the battery.

While using certain kernels with Trickster Mod and "set on boot" option, I get a reboot if the screen is off when Trickster applies it's settings. Took me a long time to figure this out. If the screen is on when Trickster applies kernel settings it works just fine. Never could figure out why this happens, but I use tasker to keep the screen on for 2 minutes after boot to prevent it.

I have the same issue sometimes, I've read around the web and it seems to be a mix of software and hardware related, I read a guy suggest removing and putting back the case (in case you have one) and I did that and the sound came back, haven't had the issue again.

So I found a solution for the issue in my case, it does seem to be software but it's really weird cause the issue continues in any firmware, it started when I was on 6.0.1 PI2, then I flashed Nougat and had the same problem (I hated it and battery drain was killing me) I went back to 6.0 and changed to the PK2 version and the issue continued, it was really weird cause it would cut out in audio messages, games but not music, I also tried every single suggestion on every forum and post I could find EXCEPT the Soundabout app, today I gave up, installed soundabout, selected media to speakers and bam, problem solved, I still need further testing, but it seems ok for now, keep in mind that I also have "prevent USB audio routing" on and "Easy Mute" off.

I was told to remove all paired bluetooth devices (on/off doesnt matter) then go to settings>connections>more connection settings>nearby device scanning then turn off... worked for me... (sorry for zombifying an old post but as this is still current with mine and many devices i decided to help)
