[LG Optimus 2x] hkkp:
Got my O2X three weeks ago, no rooted. In the first day it went freezed (blackscreen) 10+ times. it happened in different situations,

. while charging via USB.

. during a call, after I finished the call the phone was like dead, I couldn't hung up.

. doing nothing, it was just on my desk.

And it auto reboot few times too. The LG booting sound woke me up at middle of the night, like alarm clock. :( The second day I did a factory reset. It seemed got a bit better, only happened 2~3 times a day. (should I feel happy for that?)

When this freeze problem happened, I'd try to make a call to this O2X unit by using another phone. From the other handset I can heard the phone is ringing, but the O2X unit (in front of me) has no responds. So I believe the phone was not really shutdown, it was just somehow felt asleep but couldn't wake up. This is more worst than actually shut off, though. If people calls me at this time, they might think I am not answering their call...... :confused:

I read quite a few people talking about charger here. I am sure that is not the case. I never have problem with LG AC charger, th problem happened to me while charging was via USB connected to computer, and I used the same cable for both USB and AC. I also tried HTC charger and other no name charger I bought from street stall, no problem at all. I would say this freeze problem is nothing about charging. It only happened when the screen goes black. I'd try to press the power button when the screen just gone black (within few seconds), everything seemed normal. But after say 10 more seconds, things might getting weird.

Ended up I bring it back to the shop where I bought it. I told the salesman about this issue, he didn't ask anything then gave a new replacement. two weeks now, the new unit is working fine, no more problem. ;)

BTW, both units have exactly same baseband version 1035.21_20110218, kernel version 2.6.32.9-dirty, build number FRG83G and LGE version LGP990-V10a.
[LG Optimus 2x] nold-i-spolen:
Just updated to:

Baseband version 1035.21_20110405

I forgot to check what version i was updating from

Lets see how it goes
[LG Optimus 2x] nold-i-spolen:
Well, it just shut down (as in needing a battery pull)
[LG Optimus 2x] SBMkee:
-

Hey,

im also new for android stuffs, but i really want to buy a phone like this.

is there anybody, who has a properly working one ? or everybody has this issue ?

i have already ordered this device, so it will arrive @ Monday or maybe on Friday..

So what are your suggestions ?

And did everybody get this error ?

cheers,

SBM
[LG Optimus 2x] kostasalfa:
Sh$$$ it just happend to me too shortly after updating the baseband!! Didnt even give me some time to cheer!!

But it was on first boot, so probably i will give it another chance!!
[LG Optimus 2x] .:george:.:
Well, it's been a week now since I've flashed Paul's custom rom (FR10 at the time). Before that on stock rom I've experienced 3 or 4 shutdowns in a week, not while connected to AC adapter (just random time of the day). Since flashing a new ROM problem seems to have disappeared, I can't tell if it's gonna go back, as I said, I reflashed a week ago. *knock knock*

What happened though was one reboot when I was editing something in some app, so I blame the app for reboot, no reboots since then (saturday).

I'm using original charger, my phone's baseband is 1035.21_20110218, build FRG83G.

I hope the problem really is gone and that this post helped.
[LG Optimus 2x] spawndk:
I never had any shutdowns on mine - now one month old

Only modification I have made, is installing and using Go launcher instead of LG launcher, and not using the LG weather widget. Else everything is default stock rom

I bought one for my son also at the same time - he has had some random shutdowns, he is using stock launcher - no modifications on his.

Perhaps try using Go launcher instead of LG launcher ?
[LG Optimus 2x] bryant_16:
Oh my.. shutdown again after the new update? That's bad.. how is it going on now??
[LG Optimus 2x] awf:
Well I'm back to the default LG launcher from launcher Pro and leave all running in the background except car home kit (stopping manual once after boot) ;-)

- Removed the battery widget and leave the F mobile setting listener service running...

- So I'm back to a default setting and have a few custom widgets running.

- Back to the default lock screen with pattern security enabled...

- Phone is non rooted from the start

Have the feeling that all the default LG services need to be running for some strange reason by LG...

At this point no reboots no lockups uptime now 57:42:18 so going to see if this helps :-)
[LG Optimus 2x] hatrole27:
Try to update to paul's ROM (FR11, latest ROM). This will make your phone run smoothly and fast and best of all eliminate the random reboot in my case.
[LG Optimus 2x] AyYusa:
application can lead to
[LG Optimus 2x] vicster:
Stockified my phone last night, update to the latest radio via LG-update. Been running ever since noat reboots at all, been chargeing with original LG and thru usb

Still watching it closely

/vicster
[LG Optimus 2x] AyYusa:
Install the new and current vesiyon
[LG Optimus 2x] Artemon9:
I cannot update..:-(

LG app says: there's no update :-(

I'm on stock v10b, but rooted.

Do I have to unroot?
[LG Optimus 2x] mikeyd85:
Same. I tried unrooting. No joy.
[LG Optimus 2x] 1695:
You just have to wait for the update to be released in your country. Be patient.

Or flash with Paul's update.

Let's focus on the real purpose of the topic ;)
[LG Optimus 2x] siggehandf:
Been using the LG launcher for a while, switeched to ADW launcher yersterday and haven't had any problems. Maybe it's a LG widget or software that is causing it?
[LG Optimus 2x] MrThomsen:
I don't seem to have this problem. Atm my O2x has been unplugged for 15 with medium use still have 42% battery left. I do remember it draining some battery at first but then i used the controls in the notification bar and turned of the GPS and no problems after that (did some other tings to but a believe it was the GPS that used most of my battery at the time).
[LG Optimus 2x] dkb218:
Getting the G2X next week. I hope this isn't a problem with the USA version. This will be my first LG phone. First problem, it goes back to T-Mobile and I wait for the HTC Sensation.
[LG Optimus 2x] Vertigood:
Just updated my phone..lets see what happens :)
[LG Optimus 2x] Glutues Maximus:
Updated earlier today, still the same screen freezes (goes black).

Is it just me or does everyone elses screen/battery go quite warm if you don't pull the battery straight away after the screen freeze. Leave it for say, around 10 minutes. I'm starting to think this is some kind of HW-failure :(
[LG Optimus 2x] naimmkassim:
Did any of you use software "Any cut" download from market?

I use before and activate the Hidden menu, since then the reboot problem started.

After diactivate the hidden menu and remove "Any cut", no more reboot now.

Already 3 days without reboot :) Cross my finger hope this is the source of my reboot problem.

P/S: Previously I face 2 times reboot after receiving sms from someone. I already use my O2X for 1 week now.
[LG Optimus 2x] vicster:
In back again with a new update:

Still runing complete stock with latest official update.

Phone has been running stable ever since i updated at 20:20 tuesday, been chargeing in the original charger all night.

Later today i will root and flash modaco r12 and see if the phone continues to run perfectly

End off report

[LG Optimus 2x] bidurmarasini:
hi . getting optimus 2x this week end .. any suggestion ?
[LG Optimus 2x] MrThomsen:
My O2x just froze yesterday just before going to bed, so it doesn't seem that the update stopped the problems for my phone =/
[LG Optimus 2x] lmerega:
Second night passed without problems using stock rom 10a with root enabled and w/o Car, F-Sec and some others.

Still using a 350mAh charger.
[LG Optimus 2x] doncoop:
Don't use the wall charger :P
[LG Optimus 2x] 1695:
Keep in mind that we DON'T know the cause. Let's not assert unproven things. The only reboot I had was after a charge from my computer.

Made about 5 full charge from wall socket without any problem.

Have a good day, reboot-free I hope, though !
[LG Optimus 2x] withoutwings:
Happened to me just before in my pocket, and yes it was warm(er than normal). The battery had lost 10% of charge after I pulled it.

Although I don't think it's hardware related as what someone earlier observed (via ADB) was that a certain low-level kernel process (scheduler? I can't remember..) gets stuck at 100% CPU usage and means the phone won't respond any more.

Sent from my LG-P990
[LG Optimus 2x] vanahaim:
Me too.. Almost whole day without reboots, but now are back :(
[LG Optimus 2x] philliid:
Power-off and lockup Summary

After reading through this thread, I think there are various issues causing the problems, some software and possibly some hardware related, summarised below.

Hardware related:

1) Phone locks up when charging, only solution is to remove battery.

This seems like a hardware fault, either relating to charger or phone itself. Some people report no problems, others report USB charging works ok, others that a different makes of chargers works better. Some people report issues only when battery charge is < 20%.

Most chargers these days use switched mode power suppliers, these are inherently noisy and need to be carefully filtered within the charger and on the phone itself. This noise can be coupled onto the power supply of the different IC's in the phone. Because not everybody sees these issues, I am guessing that this is related to tolerancing on the filtering components.

Software related:

1) dexopt running in engineering mode

Summarised at MoDaCo (search for thread lg-screwed-up-bad-heres-why-your-ui-is-jerky) and fixed by Paul at MoDaCo. Causes slow downs and random weirdness, e.g. when using music player

2) F-Sec and Car apps

Possibly cause phone to run slow and phone to reboot - no lockup

Please correct me if I am incorrect or have missed anything off the summary list.

[LG Optimus 2x] lmerega:
I do think that it must be something related to warm.

In fact, using the 1000 mAh charger, my battery goes to 37° celsius.

Using the 250 mAh, it's under 30°.

Moreover, I unplugged my Phone 2 hours ago and it's still 100%. I have not used it inany way, and the batter is 22°.

Looks like a cold battery is better than a hot one...

Just my 2 cts.
[LG Optimus 2x] lmerega:
Update available in Italy too. Updating now.
[LG Optimus 2x] lmerega:
New stock version
[LG Optimus 2x] 1695:
Hi,

New reboot, and again occured when I clicked "Unmount SD Card to safe remove".

My reboots are definitly linked to SD card (got three of them, all when acting on it : activate mass storage, deactivate mass storage, unmounting SD card...).

EDIT : precision, I haven't be clear enought : the problem in my case seems to be linked to actions on the external SD card, not the card itself.
[LG Optimus 2x] nold-i-spolen:
There is no 'cure' for these problems yet, but some people have experienced a reduction (some even a complete stop) of random reboots using the Fr-xx-.

Try it and tell us your experience.
[LG Optimus 2x] bryant_16:
Have you flashed?
[LG Optimus 2x] doncoop:
I've not had any more reboots or BSOD's.

I've completely walked away from the wall charger and am only using PC / PS3 to charge the phone. takes FOREVER but nothing bad is happening so I'll live with it.

Battery drain is still a drag mind. If they fix the cell standby I think I can get 2 days out of this puppy.

Come on LG give us an update!!!!
[LG Optimus 2x] mikeyd85:
Can't say I've had massive battery drain issues...

Left phone at 7% charge when I went to bed at midnight, alarm woke me up at 7am with 6% charge remaining. I'd easily get two days if I didn't use it for hours on end.
[LG Optimus 2x] doncoop:
Excuse no linky (@ work so keeping internet usages as low as possible) but Danish site reporting gingerbread for June / July according to engadget.com
[LG Optimus 2x] 1695:
Again, my first O2X rebooted even if I always use the computer to charge it. Took 10 days before the first reboot though.

The second one, charged by computer too, reboots when performing any action on the external SD card (accessing files, demounting, enableing mass storage...). Not every time though.

Bottomp line is : always used my computer to charge my phones, and still, got reboots.

Yup, saw that too. LG is starting to piss me off. :@
[LG Optimus 2x] spawndk:
Could be related to bad partitioning/formatting of your SD card

backup content and reformat SD Card using the phone
[LG Optimus 2x] mikeyd85:
http://www.androiduknewsetc.com/201...tting-down-and-update-to-gingerbread-in-july/

I've got another place printing the news that there's a problem :)
[LG Optimus 2x] jivemaster:
Good work. The more stories published the better.
[LG Optimus 2x] sebsal:
I sent mine back for repair as it froze every single time I charged it. The company I returned it to say they've tested it over the last 3 days and cant get it to freeze.

Assuming they're telling the truth, the only thing I can think of that would be different for them is the phone no longer has my Sim Card or my Micro SD card.

My Micro SD card used to be in my Hero and I didn't format it in any way before using with the 2x.

Probably clutching at straws here but maybe it's sim or SD related?
[LG Optimus 2x] mikeyd85:
Could someone who has this issue please record a video (with time stamp) of

A) You putting it on charge

B) You trying to wake the phone, only for nothing to happen

and pop it on YouTube?

I'm going to contact BBC Watchdog on this one. ;)

Edit: Sesbal - I formatted my SD card before putting it in my Optimus 2X after it had been in my Hero and have the same issues.
[LG Optimus 2x] Wwax:
Will do when i get mine back from "repair" (nothing was done) restarts efter 5-10 minutes twice then hangs (ie black screen battery pull) battery at 30-50%.

Same issue when i use Ericsson, HTC or LG original charger.
[LG Optimus 2x] 1695:
Nope, did that on both cards, didn't solve the problem.
[LG Optimus 2x] vanahaim:
So, the situation about reboots is better for me after I checked the option "manual network search" and have chosen my provider..
[LG Optimus 2x] arielext:
How? I only see an "automatic choose preferred network" (or some in the likes) and when i press it jumps back the previous menu (which is the mobile network settings menu)
[LG Optimus 2x] vicster:
Also in danish Technews

LG better wake up and smell the coffee soon or this might go down i flames for em'

[Edit] [Status Update]

I updated my phone on tuesday at around Eight a' Clock, before i did that i stockified my phone completely via NVFlash

I have yet to experience any problems with reboots, shutdowns or anything of the sorts. i had all the above trouble while running custom fr11(10)

not saying that the MoDaCo is the issue here, at all. Since people on stock also seems to have problems.

Phone still going strong, been chargeing in my Original LG-Wall charger, my PC, my Mac, been playing around with different launchers listning to music while going to and from work.

the phone is buggered quite abit due to all the LG-CrapWare but non the less running without any issues..

[/Edit]
[LG Optimus 2x] vanahaim:
Strange.. I have this option.. :confused: (latest modaco rom, latest baseband). But it's not the final solution of rebooting - every hour interval is reduced to 2-3 per day.
[LG Optimus 2x] 1695:
Quick question :

I saw on another forum that somebody from LG might have said that the bug is caused by "debug mode enabled" (yeah, ironic huh ?). I seriously doubt it (if it was that simple, LG would have fixed it yet, plus debug mode is supposed to help fix bugs, not create one)... Anyway, debug mode was ON on my device when crashing, so I can't really judge, what about yours, just to be sure ?
[LG Optimus 2x] xmoo:
My debug mode is disabled from day one.

And only withnised 3 times that the phone shut off and I had to remove battery.

And I got it since day 1 release.
[LG Optimus 2x] djmcnz:
And yet how many of you have gone to the effort of setting up a log collection so we can actually see what happens?

Mine has locked three or four time total (+4 weeks) and I have logs from two of those but it simply doesn't happen to me often enough. If we have logs we can cut down on the idle speculation.

In one case mine was an out-of-memory race condition (which supposedly can't happen in Android) and the other was a power subsystem failure. Both software, probably not related.

Some of you are experiencing it multiple times per day, when the phone is not being used. Well it stands to reason it's also happening at night.

Why not plug the phone into a computer before you go to bed and start spooling the logcat output to a file?

If when the phone crashes the log will stop and you'll have a clear indication at the end what was happening at the time. It may not tell us the cause but it will show the symptoms which may help us with the cause (even if we can't do anything about it).

adb logcat > mylog.txt

Feel free to PM me if you get a good log. Although they should all be posted to www.pastebin.com and linked to in this thread.
[LG Optimus 2x] mikeyd85:
The main issue with that is on a USB port, the phones don't tend to fail.
[LG Optimus 2x] khyaris:
Then try with adb wireless if your device is rooted..
[LG Optimus 2x] Glutues Maximus:
I'll definately try that when I get home. Thanks for the tip!
[LG Optimus 2x] mikeyd85:
I did not know about that. Hmmmm. I'm taking this one back on Saturday for a new one. If that one crashes, ill root and test. As it is, I've unrooted this one for now and won't have time to test.

That really is a nice tip there... nice one.!
[LG Optimus 2x] yongwk:
Hmmm guys, i have just unroot my phone. Revert to stock Rom and baseband. Upgrade using LG software to the latest Rom and baseband yesterday.until now, no more freezes and hanging! Try it
[LG Optimus 2x] naimmkassim:
What is your latest rom? 2.2.2? baseband?

Naim
[LG Optimus 2x] vanahaim:
I did it - complete reflash - and whole night (7 hours until now) without reboots.. :)
[LG Optimus 2x] lmerega:
72 hours still going... no reboots using 350 mAh cchsarger. This night I'll try the 1000 mAh
[LG Optimus 2x] 1695:
Still got reboots frequently when accessing external SD card, and after having formated it from the phone (SanDisk SD card). Tried multiple cards, same issue.
[LG Optimus 2x] Blizze:
Here too, no shutdowns and I have tue phone for a week now.
[LG Optimus 2x] bamso:
From stock till modaco fr6 or 7 i had reboots and freezes, but since then it has been running very smooth, and no real errors.
[LG Optimus 2x] vanahaim:
So, I think the flashing of whole bin file (latest firmware) + baseband can be definetely the solution of random reboots (at least for me).. Thanks nasirahmed for posting!

PS bin file contains a lot more than system, recovery etc. so restoring of latest modaco doesn't destroy positive effect.
[LG Optimus 2x] Cronner:
First it was reboot's now it just got all black screen on both mine and my girlfriend's 2x needed to pull the battery, clearly the phone has issues.

It happen's on both rooted and unrooted

Have made asupport ticket til LG
[LG Optimus 2x] 1695:
How would you do that please ?
[LG Optimus 2x] bryant_16:
Same here. Also having the black screen then need to pull the battery. Are you using the lg stock charger?
[LG Optimus 2x] bryant_16:
Are you rooted??
[LG Optimus 2x] Vertigood:
Since I updated..(day before yesterday) I've had no lockup. i should mention that I don't use my phone at work so it's not on 24/7. But still...

Battery is pretty sucky though. It can drop 20% within 1 hour if I use the phone..maybe some webbrowsing and a short call or some gaming. :( That I don't like.

Batteryuse it says 50-60% when it's idle (radio). What does that mean?

Been charging from both original charger and through the computer.

Not rooted.

EDIT: Ok, short after my reply yesterday I installed the Launcherpro app and tried it. Shortly after that the phone froze. And during the night it had froze again while charging. Battery at 100% when I turned it on.
[LG Optimus 2x] lmerega:
Same here. Yesterday evening, while browsing the Internet, phone rebooted. No more ideas. Any official answer from LG yet?
[LG Optimus 2x] Mittaa:
Random Reboot poll

Hi all

It would be nice to know how many people experiencing this problem.

In XDA Atrix forum people have a similar problem and polls show that about 30% of the people (reading that thread) have this problem:

http://xdaforums.com/poll.php?do=showresults&pollid=4438

I do not know how to create the poll ... so one of you have to do it :)
[LG Optimus 2x] xmoo:
I remember when I did some Android phone testing some device from Acer & HTC had the same issue.

That was fixed by software. The reboots were cause by the memory management.
[LG Optimus 2x] Koyuki-kun:
I've had it too. When i put the phone on the charger at night i have had a 50% chance of the phone turning off by the morning.

Maby it's got something to do with the way the battery stops charging at 100%, in stead of not letting more power in - it accidentally decides to power down completely
[LG Optimus 2x] Miracle1980:
But someone mentioned before that the phone shutted down even during calls, so i don't think that is related to the way of charging.

I ordered my phone already and i hope that there will be a solution for this ''major issue''....
[LG Optimus 2x] KernelCrap:
Mine just shut off it my pocket. Not a technical shutdown as I had to take out the battery for the phone to show anything on the screen.

Hmm....
[LG Optimus 2x] djmcnz:
Can you trim the kernel log and post it to www.pastebin.com?

Ideally the excerpt we need is the few mins before the reboot and about 1 min after the reboot.
[LG Optimus 2x] Naadi900:
Will do, edited my post while you posted this. Here's pastebin: http://pastebin.com/shtnKyfm

How could i forget about pastebin haha.

Hope it's usefull!
[LG Optimus 2x] chrisdok:
I seem to get this problem when charging using the adapter, no problems charging via USB though. Happened 2 times in the last 3 days. The battery was at 50-70% ish in both cases.
[LG Optimus 2x] DenZj:
Hmm weird pronlem.

I've noticed some spontanious restarts im the first couple of days when rooted. The restarts where when i snoozed/pushed on some onscreen buttons while still some asleep. This was while the phon was charging/full and still on juicing.

After freezing the carhome app and installing an different alarm (gentle alarm app) i didn't have any freezes so far.
[LG Optimus 2x] mfmarasligil:
hope that its just about software. :mad:
[LG Optimus 2x] Sir Anselm:
Well, I overslept this morning. My 2X had shut down during the night, connected to the charger.

Had to pull battery...

Android-version

2.2.2

Baseband

1035.21_20110223

Kernel

2.6.32.9
[LG Optimus 2x] Eddiemc:
Same issue as the rest.. Phone dies during charging. Tried both a htc charger and the original charger. Same problem: Only when connected to the ac power.

It seems that the phone does it after it's become fully charged: If left on it will reboot, and if no user input (unlock etc) it will die. Hence every morning I wake up to a dead phone and have to pull battery.. If i wake up during the annoying startupsound and unlock it, it will mostly reboot again after a few seconds to a minute (once or twice), then be working normally after that..

23th february baseband and the 32.9 kernel as with everyone else with the issues.

For those who have not had any issues, what baseband/kernel are you on?

There seems to be a lot of us having this issue, anyone know anything more of what is causing it? The rma/postage/hassle thing will take a lot of time, so if it's software it can be fixed.

Wish you all nice working phones..:)
