O2x freeze after intensive use: SW or HW ? - LG Optimus 2x

Hi everyone,
i could read a lot on this forum about the software issues of the o2x but i couldn't find someone with the same problem as me.
I'm using the stock v10b rooted, without F-Secure or Car Home and I can keep the phone running for days and it don't reboot or crash in any case.
But when use some app ( ie: angry birds) who make the CPU run a bit more the phone tend to heat a bit but the app keep running smoothly. BUT once i leave the app to get back to the homescreen. There my phone freeze, the screen remain active and i can't make anything else than removing the battery, wait a bit and start it again.
I don't know if this is purely a SW issue that i can fix with any of the xxRom available on the net or this is a HW issue and i should return it. ( unrooting etc... before )
Anyone have an idea on this? Or a method of logging the error to find out what could cause this?
Thanks a lot.

I'm returning mine, just ordered sgs2, i got tired of light bleeding, freezes and reboots. I payed 500€ unlocked, for this price cannot close my eyes on all of this, can't take the risk of beeing hw problem, in my opinion if it was sw problem it was allready fixed. I also have a toshiba folio 100 with tegra 2, same problem there reboots and freezes. No more tegras for me

I have had mine now about a month and only ever did a battery pull once. Its very rare that you need to do a battery pull, just do soft reset instead. Works for me.

Been using Pauls MCR roms. Never once had to pull the battery. But had to pull it out once on stock though. Currently using fr17 and I have to say it's really fast and stable.

Thanks for your answers, i will try the FR17 and see if the problem persist. If it still the case i will probly return it or wait a bit that lg make some update to make sure they can repair it when i return it.

[Q] Nexus1 rebooting loop problem

my n1 having rebooting loop problem when i use it continuosly for 5-6mins or performing some task.in airplane mode i can use it for 30-40mins but then restarts and keeps restarting until i give it 3-4min rest before starting it again.probably this happen after 2.3.3 ota updat.
Wipe data (factory reset) and try again.
If it doesn't work - use "unroot/restore" guide in Wiki, PASSIMG with FRG33 image, test it.
If still reboots - use the warranty, something's wrong with your HW.
You can also look at the logcat to see, what is the problem that causes the reboot. Looks like something's overheating.
i am Having the same problem, i have unlocked bootloader and installed the latest cyanogen rom hoping the rebooting problem would be fixed but no luck ,,the rebooting or the overheating what ever causing it persist.
i don't know what else to try??!!!
i really like the phone and don't feel like buying a new one yet. nothing on the market right now convinced me to ditch my n1.
i am just sad that the hardware life span of of the n1 is 1 year only.
yah thats is overheating causing it.because when it becomes hot it goes into restarting loop until i cool it down.still dont know exact problem though.

Isnt the warranty void after you've unlocked the bootloader?

I had that problem when my CPU speed was over 1000. Maybe this'll help?

I don't think it's the cpu because since 2 days ago the phone started rebooting while charging without me working on it. so now i have to turn it off before plugging the charger, or it will hang on the x for hours.
i guess it's time for me to look for a new phone..too bad, i really like the n1.
yes nothing wrong withcpu its hardware problem.i also cant recharge it while on.
i keep it in fridge then it work fine.after little heat up it goes into loop again.
I've also had the rebooting loop when I had a bad battery fwiw. Changing the battery to a new one solved the problem.
I was having the same problem when it's charging (and I use the N1 a bit) and when I use the 3G data (surfing the web, installing apps from the market, etc.)!
And it's the 3rd time that I've sent my N1 to the Tech Repair!!!
Never repaired the first 2! I hope this time will be ok... I'm waiting for my Nexus 1 to come again with me...
This seems like a big N1 defect.
I called HTC today. Out of warranty repair in the USA is 55$ to 283$ plus shipping.
Could have bought a Nexus S for the 500$ I'm spending on repairs + devices.
*************
Update 5/5/2011
HTC fixed mine even though I unlocked the bootloader. No charge. Free overnight in both directions.
this is making me so much angry.although my n1 is in canada warranty but i am now in pakistan so dont what to do?even we dont know about the exact problem.is it board or something small problem?

[SOLVED] All of a sudden I get horrible battery drain.

I am running the stock V10c ROM with 0405 Baseband and root.
Until recently I had little to complain about, but since last Saturday my phone has a horrible battery drain.
It turns off within 6 hours after I unplugged it even tho I did not use it and it was sitting calm in my pocket. This happend for the third time now since Saturday.
I was suspecting the recently installed Vlingo or Google+ Apps, but after removing them I still have the same issue. I recalibrated the battery yesterday but the Phone turned off again today.
I recharged it just now and it got incredibly hot like it has never been before.... this is very strange.
Anyone else experiencing something similar?
Have there been any recently updated Apps that are said to cause battery problems (Google Maps got a recent Update...)?
Any suggestions?
(I hope that damn OTA update comes soon and fixes this otherwise I'll have to update it manually or will have to install a custom ROM.)
EDIT
I flashed MoDaCo's MCR Fr19 and the Problem is gone.
I guess a factory reset would have solved my problem as well, but since I had all the work with backing up and restoring anyway I have chosen to go with a nice custom ROM.
Everything works like a charm again!
I used to get horrible battery drain, and generally the battery stats would have a mind of their own and change at random..... sometimes a phone restart would fix this, sometimes not. This was the biggest problem I had with the phone, but by no means the only problem.
I was always on stock, but since flashing the newest Modaco ROM (FR19) I've not had a single problem, the phone actually works as the piece of high-tech gadgetry I expected it to in the beginning. It's been nearly 2 weeks since switching to a custom ROM, and finally I'm loving this phone. I was reluctant to do it earlier as I waiting for the official LG updates, but after all their tardiness I decided enough was enough and went Modaco.
My advice: if you're unhappy with the phone as it is, try at the very least 1 custom ROM (both Modaco and Cyanogen are popular) and see if it improves your experience.
I have this problem too sometime
Only solution is to turn off the phone and turn and everything become normal
But after sime day if use same happens again. I suspect there is a program start to run in bg non stop
Btw i am in fear edition 12.2

Ermmm.... correct me if im wrong, but to my knowledge v10c roms uses 622 RIL.. which has a 622 basebnd too.. why are still on 405 baseband? I really recommend 622 baseband as its the least power hungry baseband I've used since 405, but then again, some other factors might affect ur battery too.. but alot of ppl give positive comments on 622 baseband
.. shld give it a try.

Thanks for your replies!
@Crofteh
I am generally a big fan of custom ROMs and always used one on my last android phone, but I liked the stock LG ROM enough to keep it until Gingerbread would arrive. I hoped to test official LG GB without wiping and then upgrade to a GB build of MoDaCo or CM.
That is what I thought, but who knows how long LG will still need for GB.
@Netuser
Thanks, I also suspect some App to uselessly run non stop as the phone feels warm near the camera, which indicated SoC load.
@tablights
I have the unbranded German version which came with a V10b ROM and a baseband number I forgot. After updating via the LG PC tool it changed to V10c and 0405 Baseband. Since that there was no official Baseband update for my phone. As far as I know, the German Vodafone branded phones got the 622 Baseband in last weeks update.
I will try to manually update to V10e via KDZ updater since it apparently does not wipe in the procedure.
Should the issue still persist I'll give MDC r19 a try.
I think the best bet to avoid the heating problem is to remove the micro SD card. Or try another one not greater than 8G. Don't use 16G or 32G - less costly for you if it burns out.
How is that related to the SD card? My 16GB card worked flawlessly all the time.
Same here
Hi,
I had exactly the same Problem, Phone got incredibly hot, was always warm even in airplane mode and died after 5h in stand-by. I tried all Basebands, different ROMs, reseted the battery stats several times, tried charging and uncharging several times. I logged the battery usage and got it down to maybe 20mA which should give me something like 75h in standby, still the phone shut off after 5-6h. I didn't use a SD-Card so it had nothing to do with that and it didn't change with different Software so i'm sorry to report: it may be a hardware problem. Either the battery broke or the handset itself didn't survive the temperature and is now draining (you could try another battery).
I sent my in and DHL lost the packet so no more Info from my side
btw, i also had the german version bought at Amazon.
Good luck finding the Problem !
I hope it won't be necessary to send it in. At the moment I am trying to rule out all possible causes. I signed out from the google labs project that lets you download parts of maps, since I activated that shortly before the problems begun and I could imagine that constantly downloading maps could cause high battery drain.
I have no time to do a custom ROM install including all backup and restore stuff atm as I am busy writing my diploma thesis for the next two weeks. But I will try that if nothing else helps. If that does not help, I will send it back.
Did you get an replacement or a refund?
If you got a replacement, does it have any issues like backlight bleeding ?
If you got a refund, did they pay the price you bought it for or the price it costs now? Cause there is a steep difference in price from then to now.
Juice Defender?
I had the problem and the problem is solved after I install juice defender.
I'm still in the process of getting a refund.
I think they will pay what i payed. But it is exhausting getting them to do anything and while i do that I'm back to my good old and terribly slow G1
Good luck with that!
Would be nice if you could let me know how this was resolved so that I can decide what is the best way to go should things not get better.
Thanks!

[Q] Galaxy note keep turning itself off randomly

Hi
I am new to Android world. So please handle with care
I used to use an iPhone. Recently (bout 3 weeks ago) I bought a galaxy note and am loving it.
I was going through a lot about Android system and found out 'rooting a phone'.
so I rooted the note and installed Rocket rom v22, GoLauncher Ex and few apps like Setcpu, Adfree, Bank, Xchange etc. I don't have games or many apps on my phone.
My phone turns itself off randomly every now and then. during phone conversation it rebooted itself once so far. and when my phone is stand-by, I found my phone is turned off.
I am not sure why it's happening. Is there any settings i shouldn't set?? or ???
Could anyone please tell me how to fix this issue?
If the phone is faulty, I need to make my phone as the same as when I first got which I am not sure how to :-( yet
The first thing to do is go completely stock. Flash the lastest stock rom and see if that fixes the problem.
When using ICS ROMs there's a known bug called Sleep of Death (SOD) that is similar to what you're experiencing. The phone simply won't turn on the screen and you have to press the power button for several seconds to turn it on again.
Almost all GNote users experience this issue so don't worry about it. Going back to stock will not solve the problem.
Hi
Thanks for the reply.
Before the rom v22, I had v19. my phone still did turn itself off several times. after flash the room v22, it didn't happen as many as v19 so I am not sure that the ICS causes the issue.
anyway, I will try the one you suggested and see how I go.
Thank you

I am more worried about the alarm. if the phone turns itself off while i am in sleep, i won't be able to hear the alarm going off.
well if that happens again, i might have to get a alarm clock.
i was thinking of setcpu app might cause the issue... not sure though.
Thanks for your help
I experience the same issue when i was running stock. I've tried several stock versions but the problem still exists.

I have definitely never ever experience SOD when the phone is stock and lock.
The only time i did experience SOD is when i change to modded kernel.
I'm running stock with cf root and have never ever experienced this, so not all notes are affected. That would really suck!

Never had Sleep of Death on stock rom.
I am on stock ICS Rom n it has happenedwith me twice.
My GNote goes dead randomly and only starts up after pulling out battery.
Weird!
Install an ICS from Clean
Start from a Stock ICS rom using PC Odin, then follow my Post as follow :
http://forum.xda-developers.com/showpost.php?p=26772618&postcount=12
Try another rom other than that you had, or a higher versionof it.
The MIDTEAM v1.4.2 is Good and Stable.
Good Luck
I had this problem most of ICS ROMs on my Galaxy Note. SO I guess it's an ICS related bug and it is very uncomfortable to have to reset it to unlock it .
I too have tried several Stock ROMs but it still gets into the Sleep of Death at least once a day.
I guess that it should help to have a Kernel that changes the Deep Sleep settings...
Of my 2 GNotes, one of them had this problem. Happens when you put the note on the table with small drop or whatsoever.
The problem disappeared when inserted 3-fold 80g paper between battery and the edge of battery compartment. The battery tolerance is not so tight so when small drop (like putting on the windowsill) happens, the phone shut down.
The problem completely disappeared after inserting paper.
Of course, more professional would be go to Samsung repairs and show it and ask for replacement - either battery or phone internal casing. You can reproduce the problem by turning the screen on and dropping phone 10cm into hard surface.
But I did not bother.
I won't say that yours has exactly the same problem. But check the tolerances of battery 1st. Sometimes solutions are too obvious to see 'em.
I upgraded from stock to CM9 3 days ago and my Note has turned off several times a day since then. Never before upgrade, so I don't think it has to do with battery being loose in its compartment - not in my case.
I am loving ICS, but I will have to downgrade to gingerbread to get rid of this irritating bug.
this is happening to my galaxy nexus!!! yeah it turns off at random like sleep of death and small drops can trigger it. if i knew this could happen i would have never rooted
lol root itself has nothing to do with it.
if small drops cause it, and paper adding in compartment fixes it. its the gap between battery and whatever should fixate it.
if it occurs during deep sleep, dig into logs what you can find there. Also check roms/kernels feedback if others have it with that version. Many ways to illiminate possibilities.
I miss some good analyzes in this is issue from those experiencing stuff. Android I guess is not user friendly that way.

Galaxy Note Sleep of Death on 4.1.2 JB
I'm still trying to figure this out... I had hoped that with Samsung Stock upgrade to 4.1.2 it would be fixed but its not... anybody still experiencing this problem?
Things that I have tried
Move all apps from Internal SD Card (USB) and format
Factory Reset
Paper wedge between battery
Opened and re-connected all connectors to Motherboard
Install CPUSpy (deep sleep is OK)
I'm at wits end now, and this problem is very apparent. I havn't wanted to flash to a custom rom, because I've seen reported that it still happens with whatever ROM whether stock or custom
Any more ideas on how to make the Sleep of Death go away?

Turning off problem too
I don't know if it is exactly the same problem, but my GNote keeps turning off every time, but not seem to be randomly. Looks like ti shut down every time a high performance is required. I tested several roms, ICS and JB, custom and stock, but the problem still goes on.
Please, any ideas?

[Q] phone won't turn on sometimes, and requires reboots.

Its a Hong Kong bought LG P990 with GB, bought two years old. Rooted but 100% stock, just deleted pre-installed apps. At first it happened only once in a while, now maybe 1-3 times a day. It won't turn on. I don't know if its actually off or if the power button doesn't work. So I have to pull the battery and restart.
Its seems that about a year ago one day the power button require quite a bit of pressing to get it to turn on. Like I have to push really hard just to get it to turn on. Its been that way ever since. I always would have to do a restart every week or so because the thing would get REALLY buggy or REALLY slow. Then it started to not turn at all, the power button. It would do that about once a month, then once a week, then three times a day yesterday. This happen exponentially.
Its always been buggy and slow. I only have about 10 apps on it. Barely using any space.
Is it dying? How to tell if your smartphone is dying? How often do people replace their smartphones?
hi! you should try to:
a) flash the rom again and try to do it as clean as you can(try a hard reset then flash)
b)either use a rom that is already modded without the apps that you care to get rid off or watch if the problem is caused by the removal of unwanted app
c)have a little patience and test
hope it helps!

Thank you for your help. But I did the root and deletion of stock apps a long time ago. Why is this problem starting to get worst now? Or are you referring to the general slowness?
I never flashed a rom before so I don't really want to start. Unless its the clear answer to solve my problems. Is that what your suggesting? I have thought abut it, but I wonder how much worst I can make it. Plus, I am just scared I'll screw it up.
My v20s stock rooted rom was performing pretty well by my standards but after changing basebands and removing some unwanted apps i had some trouble with playstore(after using 3g internet, when switching to wi-fi it would not download or update apps) and the phone sometimes just shut off removing the battery being the only way to solve both problems.
Since i flashed the new v30a everything is peachy except the phone and that damn chrome app are a bit laggy sometimes(mostly chrome).
My advice to you is to ,one by one, try to eliminate each possible cause.Also flashing a new stock rom is not hard(and i guess neither a custom one tho i have no experience with that) so have no fear and please do read the tutorials for each rom. Good luck!

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

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

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

I hope you will find a solution for your problem.
But I have to admit I had to smile ("grinsen" in German is a much better word for it) when I saw your title:
Freezing even when >30°C
i'm not able to run device anymore but i already tried this app for checking emmc and this is the one with that bug. But it doesn't matter, because i was flashing only safe kernels, and i don't think this emmc is problem. I think the culprit is graphic chip, or CPU, or CfRF (Chip for Random Freezes)
I was not able to find any similar problem. Tomorrow, i will try to put device into download mode, flash any custom safe kernel with CWM, leave device in this recovery, and see if it freezes again. If yes, the only option is to get device warmer for a few degrees (300-350°C with my heat station haha ) and i will see if there was any cold solder joint. If not, device will be dead anyway so i have nothing to lose

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

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

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