[LG Optimus 2x] doncoop:
You can add my Optimus 2x to the list.

Received Wednesday. Charged while @ work. Came home and seemed ok.

Went about setting it all up. Then had to charge again so did while still on.

Got black screen. Phone was very hot but it was at the top for me and not where the battery is.

Removed battery, put onto charge again and it did it again quite quickly. Put on charge overnight and was still on this morning.

Just got a reboot at 50% battery while @ work, but thankfully not the black screen (phone was not hot at all).

All in all not good :(
[LG Optimus 2x] rockerduck:
I'm unistalling recent apps I put.

Myprofiles

Missed call deluxe

now I cannot reach > Settings > Audio > Volume. It crashes...

Don't know if this behaviour is reboot problem related...
[LG Optimus 2x] pulsation:
Not sure at all ; as pointed out by PatrikS, there may be a problem with cpu frequency changes. Anyway, it doesn't exclude the fact that there could be more than one problem at a time :(
[LG Optimus 2x] professor78:
Having problem with phone just turning off also, its happened 3 times now, always when on charge via mains. had it 2 days. Its at stock build (in uk)

Lg have a big problem here....
[LG Optimus 2x] jivemaster:
Seems you guys are narrowing down the culprit of these blackouts/random reboots.

I can see the factory programmed sleep setting frequencies theory being highly probable. Frequencies are possibly too low for the phone to wake up in a reasonable time after the power button being pressed, which could also cause a subsequent reboot if not attended to.

I have only witnessed one reboot while the phone is charging. Every other time it has been when the phone is idle.

I'm still wondering if I should be having this assessed and replaced under warranty or not. Warranty assessment will likey report back that the device is fine since its not rebooting constantly - just once every now and then at a random time. It would be lucky if a reboot occurred during the phone's time with technicians. I'm not sure if all the trouble (including the up to 30 day wait) will be worth it. In the end, a software issue can only be fixed by LG (or a custom rom). I am not prepared at this stage to pursue the latter because I need to keep my warranty intact in case it does need replacement.

I would encourage everyone with the random reboot and blackout issue to continue to post here so we can measure how many here are affected. Thread has had 27,000+ views thus far lol.
[LG Optimus 2x] rockerduck:
I did a hard reset just now. Only astro and ezpdf installed. Superoneclick still inside...

waitin' for next reboot
[LG Optimus 2x] 1695:
Add mine to the list to. just got black screen, totally unresponsive. LG ROM v10b, rooted.

have we any official news from LG ? First post should be updated frequently to sum up the thread, which is becoming quite hudge.
[LG Optimus 2x] jivemaster:
I totally agree. I would also encourage people to inform LG (or the supplier of their phone) about the issues so that word gets out.

Although probably the most productive method is for the issue to get some larger tech blog exposure - just like the Nexus S and Atrix reboot issues did. The more public it is, the more LG may feel inclined to actually acknowledge and fix their buggy software (or acknowledge a hardware fault and replace handsets if applicable).
[LG Optimus 2x] :
Even that I've had only one reboot, like explained earlier today, I've complained to LG about it and everybody should do the same.

Mike
[LG Optimus 2x] 1695:
So, massive email contact all at the same time, worldwild ^^ ?

That's why I'd like to get a summary easily readable on the first post, to be able to provide useful infos and TRUE infos.
[LG Optimus 2x] sebsal:
I've already emailed and called LG. They said to return the handset to the supplier as it was obviously faulty.

When I said to them there's been a lot of reported faults with this phone they said they weren't aware of this and to try a replacement first. Failing that, i'd need to send them the phone under warranty and potentially wait 28 days for a repaired model
[LG Optimus 2x] .:george:.:
They said the same thing to me, however I'm not giving my 2x away! :D I tried to flash different rom today, see how it goes...
[LG Optimus 2x] rockerduck:
1.30 hours since hard reset. No reboots so far
[LG Optimus 2x] RedeemerSK:
Maybe if some 'lucky' guy would be able to get 'stuck with black screen' while on adb (iirc) connection and get logs in the moment when he presses the button to unlock the phone (what wouldn't work obviously)

... to see if the phone was alive before button push. If it was, then we're little closer to solving the mystery.
[LG Optimus 2x] djmcnz:
Did that, see the lockups thread over at MoDaCo... post is by me.
[LG Optimus 2x] 1695:
People on custom ROMs are experiencing random reboots too...

I'm sick of LG saying "not aware, ask your supplier to switch for another device".

It's not to the community to look for workarounds ! As good as Paul is, and others are, they shoudn't be fixing LG's mistakes.

It just pisses me of.

How much emails will it take for LG to say "Yeah, we know, we are working on it" ?

Plus, I would be glad to send back my LGO2X to repair, if it was not for nothing. They'll just either not be able to reproduce the bug, are change it for another device which will reboot exactly the same after a while.

I insist, we should write some "model" report e-mail, and "spam" them until they stop saying "we are not aware of that, never heard of it".

Bye.
[LG Optimus 2x] rockerduck:
3.30 hours since hard reset. No reboots so far...

I'm thinking about the possibility of software problems causing reboots (at least in my case)
[LG Optimus 2x] doncoop:
Just a thought, but some people have said the black screen is to do with the timeout. Do the people that its happening to a lot know whether they locked the phone while it was charging or just let it timeout? does that make a difference?
[LG Optimus 2x] 1695:
The black screen occured after I locked it. I always do, never let it timeout. And it froze. Don't know if there's a link though, I'll let other people tell us.
[LG Optimus 2x] durzagott:
Black screen occurs after I lock it too, not tried just letting it timeout yet.

Had it happen to me four times on the walk home this afternoon. It was in my pocket each of those times and today is a warm day in the UK. I suspect overheating is the culprit in this case, but that's just a guess.
[LG Optimus 2x] RedeemerSK:
Hm .. as I'm no kernel expert and can't see it there ... is there in the log any evidence that the phone was running fine when you tried to unlock it and that made it crash ?

Btw, I got freezes while locked by both timeout and myself.
[LG Optimus 2x] sebsal:
Makes no difference. Locks up either way when charging.

The interesting thing for me is it does not lock up if I'm charging and listening to music, so it seems as long as the phone is doing something, it won't lock up.

However, if the phone is doing nothing and I charge it, it locks up 100% of the time. Mine does seem worse than most though and I sent it back this morning
[LG Optimus 2x] mikeyd85:
Same as you guys. First charge and it died! I hope that it can be fixed via sw update!
[LG Optimus 2x] Mittaa:
Hi

Have anybody tried to swap batteries between a faulta and a not faulty device?

I might have something to do with the battery? Or am I totally far out :D
[LG Optimus 2x] djmcnz:
No, not that specific evidence... and it might not be the same problem (same symptoms though). The log covers free, locked, re-freed but doesn't provide a ton of insight.

@all - try turning WiFi off when charging... we have a suspicion.
[LG Optimus 2x] professor78:
Hmm, I have done many many tests and reboots/lockups over the past 6 hours and I very nearly always get lockups with the combination of :

Charging from mains + Wifi + Screen sleeps when charging.

So the screen going to sleep while charging and wifi on kills it... Replicated this about 15 times.

I have ticked the option of "Stay awake" (which is in application management/development) and have not got it to lockup in 2 hours no matter what combination i try.

See if this is the same with yours?
[LG Optimus 2x] sebsal:
I've never had wi fi on when charging :(
[LG Optimus 2x] davjan:
my phone never automatic shuts off

wifi sleep policy is set to never

[LG Optimus 2x] :
This morning was a random reboot and now I've had the first freeze! Phone was resting on the table and when I remember to pick it up, it was completely frozen!

Mike
[LG Optimus 2x] 1695:
Personnally never had a reboot, but the freeze occured while wifi disabled.
[LG Optimus 2x] rockerduck:
Since I didn't experienced any further reboot (but one black screen for the first time 2 hours ago), I think it's time to better understand the problem from software side.

Could be useful if everyone specifies:

black screen or reboot problem

how often it occurs (randomly, every hour, while charging... etc.)

if the phone is rooted (superoneclick? other method?)

the launcher used

particular applications/widgets installed (e.g. profiles changers, custom notification apps etcetera)

thank you
[LG Optimus 2x] :
Lets start then.

My first reboot was this morning, two days after having received the phone.

> It's rooted with superoneclick

> Baseband 1035.21_20110315

> Clockwork recovery

> Paul dexopt fix

> Android 2.2.2

> Kernel 2.6.32.9-dirty

> Build FRG83G

> LGE Version LGP990-V10b

Only new widget is the Battery Monitor Widget and Data Counter Widget. Have also running the 3G Watchdog, the Touch LED Notification and Power Scheduler that was configured to shut down wifi and data between 0h and 8h.

After this random reboot, all worked fine until 30m ago when I've picked up the phone and was with a black screen and the only way to recover was by pulling out the battery.

I've uninstalled the Power Scheduler and Touch LED Notification and put it to charche overnight. Let's see if it wakes me up tomorrow morning like it has done today.

Mike
[LG Optimus 2x] mikeyd85:
Wifi off seems to work but my battery was at 95% + at the time anyway. Will keep an eye out. I also killed data btw.
[LG Optimus 2x] Glutues Maximus:
Phone still working fine after undervolting it. Thinking of buying a new battery, go back to stock settings to see if it's the battery thats faulty.
[LG Optimus 2x] jivemaster:
Pretty sure the wifi on/off and stay awake wifi settings have no bearing. All our reboots have happened at home with wifi on and keep wifi awake on, as well as with no wifi on altogether. I will test this theory though.
[LG Optimus 2x] ReiskaSeta:
My phone died 2 times in half hour after using wifi.. phone is rooted and using tkrom. Now removed external memocard and testing if it helps..

Android 2.2.2 and baseband ends 223.
[LG Optimus 2x] 1695:
Here are the details :

- Stock ROM

- Baseband : 1035.21_20110218

- Kernel : 2.6.32.9-dirty

- Build : FRG83G

- V10b

- SuperOneClick root

- Some apps forzen (F-Secure, Car.. That's pretty much it)

- No automatic Task Killer

Never had a reboot, but I had one black screen, after 10 days of use.

I was looking some stuf on the web, after what I locked the screen I put the phone on my table. Few minutes later I tried to unlock it : impossible. Forced to pull the battery out.

Battery was around 50%. Temp° was normal. Wifi was disabled. 3G was disabled.

Idea that might be stupid but : could anyone code an app which log pretty much every thing precisly ? Could help...
[LG Optimus 2x] hajan0512:
According to Nvidia, the bug has been filed and LG is working on it. Hopefully it will be fixed be Gingerbread released...
[LG Optimus 2x] 1695:
Well if that's really right, it would be the good news of my day (which is just starting back in France, 9AM) !

Could you be more specific on your sources ?
[LG Optimus 2x] Naadi900:
Sounds good..

You have a source?

I still blame the charger for freezes (battery pull state).

Used the sony ericson charger from my girlfriend after mine made my phone reboot immediately.

On her charger it charged my phone fine (from +-10%).

The difference is (by heart, might be mistaking) her charger is 4.8 volt and 0.8amp and the LG (had some russian on there i think..) is 5 volt and 1 amp.
[LG Optimus 2x] jivemaster:
This better not be a late april fools!
[LG Optimus 2x] durzagott:
Oh wow, that would be excellent. I can put up with it if there is a fix coming soon!

Do you mind if I ask where your got your info from? I'm twitching about returning the phone today, but I will hang on a bit longer if necessary.
[LG Optimus 2x] durzagott:
Actually, I have a similar result. I charged from my old Nokia N97 charger last night and everything was fine this morning. Nokia charger is 5.0V 1.2a -- LG is 4.8V 1.0a
[LG Optimus 2x] rockerduck:
Since yesterday 4.00pm (hard reset) I didn't have any new reboot so I think it is a software problem.

Main apps before:

Superoneclick

App2SD

Move2SD enabler

LauncherPro + homesmack

Astro

Beautiful widgets

Extended controls

Myprofiles

Missed call deluxe

Advanced task killer

Ezpdf

various markets and few other things.

Now:

Superoneclick

App2SD

Move2SD enabler

Stock launcher

Astro

Ezpdf

few markets

hope to know more about Nvidia acknowledgment sources
[LG Optimus 2x] pulsation:
Using cpajuste's kernel since yesterday noon, without undervolting, to see if governor / scheduler kernel modifications would help first. No shutdown / reboot for now, let's cross fingers :)

However, background processes drain much more battery than before, and setting governor to power save doesn't seem to be kept in Pimp My CPU.
[LG Optimus 2x] 1695:
Well you know, mine took 10 days before first black screen, and it occured after no software change in the past 3 days... So, according to me, that doesn't prove it's a sw problem.
[LG Optimus 2x] :
Well, it hasn't rebooted or freezed during the charge. Let's see how it handles during the day.

I forget to mentioned that I have F-Secure and Car Home frozen by Titanium Backup since the first day.

Mike
[LG Optimus 2x] rockerduck:
A time related problem?

We'll see what the reply will be. (I) Don't expect much.
[LG Optimus 2x] o_tiger:
Do U have freezes & reboots with custom ROMs too? With latest MoDaCo - Problem solved?
[LG Optimus 2x] kostasalfa:
If they dont respond soon, we must all try to publish these issues in sites like pocketnow, engadget, androidcentral etc.. this will have an enormus empact in a company that will try to sell millios of g2x phones to americans next month plus optimus 3d worldwide etc.. if you make such huge mistakes work on them . fast! if not, then forget the indrusty!!

I managed to somehow not having any freeze at all and only one reboot last 48 hours or so. Didnt do anything special but i ll post it..

Set cpu profiles for charging ( raised the minimun a bit ) screen off lowered to 800 max and for normal usage let it stock. Set screen not to turn off when charging by itself. When i shut it off manually no problems even when charging of course. Pretty much thats it.but it helped!!
[LG Optimus 2x] mikeyd85:
I've messaged Phandroid already on the matter to try get some media notice.
[LG Optimus 2x] jivemaster:
I did a tip-off to engadget including a link to this thread. Though they haven't acted on it yet. I asked them to ask LG for us to get an official answer on our random reboot issue. Don't know if we'll get any satisfaction though.

Maybe if more people submit similar tip-offs we can get this thing rolling.
[LG Optimus 2x] mikeyd85:
I've been emailing Quentyn Kennemer from Phandroid and he is going to get in contact with LG regarding the issue. :)

Edit: Alos: http://phandroid.com/2011/04/08/doe...oot-or-turn-itself-off-every-so-often-issues/ :)
[LG Optimus 2x] Wwax:
Update.

Sent the #¤%&¤% phone back, got fed up, the problems started again two days later but to the point it was unusable..

Only app installed was the jewels game. No other tweaks, apps, roms, launchers, nothing.

Going back to HTC and never looking back if the replacement dosen't work flawlessly..

The OX2 dosen't feel ready to be released, there were simply too many annoying small bugs from the start.

The short lag just before and after the lock screen on the worlds fastest phone is just perplexing.. Back to the drawingboard LG..

EDIT: Must add that when it was up and running it was a wonderfull phone, fast, really nice design, well built, fantastic screen!
[LG Optimus 2x] Ben86:
Hi,

got my LG2x from Amazon Germany on 02. April. Since then i had:

Blackscreens, Keyboard freezes, whole device freezes, voicecall only worked with loudspeaker (usual speaker would give a voice) and reboots.

I didnt change anything on system like root or else. I only use apps from market.

About the phone:

LG2x without branding

Modellnummer: LG-P990

Android-Version: 2.2.2

Baseband-Version: 1035.21_20110218

Kernel-Version: 2.6.32.9-dirty

Build-Nummer: FRG83G

LGE-Version: LGP990-V10b

Im not planning to send it back because i jsut fall in love with tegra :D

I really hope LG quickly comes arround with an update!

So atm my mood is like: :D -> :o -> :) -> :( -> :confused: -> :mad: -> jump to first ....

btw the kernels name fits to this problem ..."dirty" ...
[LG Optimus 2x] xantar:
At least see if it is a hardware or software problem ...

Not a good behavior on the part of LG.

It 's strange, however, that no genius by ste parties has not yet figured it would be a software problem
[LG Optimus 2x] SykesAT:
thinking about getting the G2X.

Are the problems detailed in the thread universal or are only a portion of O2x users getting them?
[LG Optimus 2x] Mittaa:
Universal or not - I'm waiting to hear some response from LG :mad:

And if no responce I will go for HTC Sensation or Galaxy 2 S ;)
[LG Optimus 2x] SykesAT:
Mittaa,

indeed. all if the issues have me second guessing purchasing the phone. Please see the poll I just made. Hope to get a better idea of how rampant the problems are.
[LG Optimus 2x] kencheung2008:
I am quite sure the one of the source of the shut off problem comes from the adapter.

I got the phone on 24 March and there is no reboot/shut down when using my non-lg-official USB adapter.

but last night, I, first time, use the official USB adapter. The phone shuts off when power is 100%.

That's !@#$%!###!

By the way, the screen may be out of control when using the non-official USB adapter.
[LG Optimus 2x] bryant_16:
Hey guys, I'm having the random shutdown today. The phone just switched off like that and I need to get the battery out then I can start the phone again.

Sigh..
[LG Optimus 2x] Triage1:
Hey everyone,

at those people whom device shuts off at loading, do you use the original usb-cable in the charger? or just plugged another one in? I've put another one in just to try if it will happen to me also.. ( it's my first load tho while phone shut down :D)
[LG Optimus 2x] amacrobie:
Have a 2X from superetrader; no issues when charging but I'm using an HTC charger with a Nokia USB cable (plugged into a 1m extension to make it reach my bedside table). Also use a Nokia mains charger at work.

Chap at work picked up a 2X from expansys two days ago; he's about to send it back as unusable as it reboots on a frequent basis. I believe he's using a motorola charger, but will check with him later.
[LG Optimus 2x] Vertigood:
I have the freezeproblem..but not often. And I have not downloaded a lot of apps at all,but! today I downloaded Nesoid lite and DroidEmu ROM..Just a short time after I got a freeze...and yet another one within 30-40 minutes!

I've now uninstalled them both to see if it happens again.
[LG Optimus 2x] xantar:
I do not think depends on the application ... It 's a problem of instability of the operating system (maybe Android 2.2 does not like Tegra 2) or a construction ...
[LG Optimus 2x] gaz31:
Had my phone since Sunday, luckily had know random reboots.

Used the LG charger the first 2 days with constant black screen each time it was charging, been using my old HTC hero charger since Tuesday with out any problems.
[LG Optimus 2x] mikeyd85:
Just testing this now. Did a fairly long charge fine. I wonder if the LG charger breaks my Hero...
[LG Optimus 2x] gaz31:
Tried the LG Charger with my Hero and did a full charge with no problems.
[LG Optimus 2x] kostasalfa:
Not a charger issue..using a nokia charger last two days. No problem during charges..but still some reboots and freeze during idle times randomly..

Help yourselfs by being heard.. here (greece) lg is not aware of any problem, and say nothing is reported!!

We must have an official answer even in the weekend.. something like..ok we are working on it..silence creates fears of defected hardware!!

Try to post your findings (not spam) and to inform lg, retailers and most important, tech sites..publicity is all we need to get some help..
[LG Optimus 2x] djmcnz:
I've been using my Nexus One charger since day one and have still experienced the problem.

I think it's important to try and distinguish between "shutoffs" and "lockups" and "reboots".

I suspect people with "shutoffs" actually have "lockups" - if the screen is off when it "locks up" it can appear to have "shut off". Occasionally, and inconsistently, the phone is still available via adb in the "lockup" state.

A reboot is rather more obvious because we can check system uptime.
[LG Optimus 2x] Vertigood:
Mine never "wakes up" again after a freeze. I've tried to wait it out but nothing happens.

In the last email i got from LG (sweden) they just said that to send it in for service is the only way I can go with "this problem"..and maybe a softwareupdate can fix it in the future.
[LG Optimus 2x] Vertigood:
Ok, have not had another freeze since I uninstalled the apps.
[LG Optimus 2x] MeX_DK:
I have managed to locate one of the reasons why the phone might reboot at random, even when its in use.

When I am downloading a large file over 3G the phone starts to slow down really really bad, and then at a certain point it grinds more or less to a halt and then it will reboot. It has just done so 2 times for me now, and did it 1 time yesterday.

So I am suspecting when it it is that the CPU gets pressed that it will then lock up and just die and then reboot.

Even attempting to simply start the download and leave the phone laying to download will cause an reboot. So here is at least one cause of the problem.....
[LG Optimus 2x] jivemaster:
The charger thing is just a coincidence. Many have had the issue both with and without charging. Only one of our reboots here occurred while charging. Every time it has occurred - either a reboot or black out, it has always happened after the phone was left idle. When using it, it never has the issue.

It's more likely software, battery or something deeper like a true mass hardware fault (the latter of which I hope is not true).
[LG Optimus 2x] naimmkassim:
Just got LG2X yesterday..18 hour usage with 1 time fully charge all night 100%..no reboot or shutoff so far..

P/s: im using my HD2 charger since i dont want to waste using new charger although the old charger (hd2) can still be use..
[LG Optimus 2x] debuf007:
That is what I have run in to as well. A battery pull should do the trick.
[LG Optimus 2x] hikkifans:
Yes, every of my reboots occurred while it was left idle.

And freezes occurs when idel and charging.
[LG Optimus 2x] Artemon9:
I've got my phone since wednesday.

I never used LG's charger before.

I used my Omnia2's Samsung charger, or USB data cable to charge the phone.

Yesturday evening I tried LG's charger.

The phone shutted down and the back of the phone was hot!

There wan not any shutdowns or restarts until this evening. :-(
[LG Optimus 2x] Vertigood:
Maybe some chargers are faulty..as well with other stuff :(
[LG Optimus 2x] naimmkassim:
Good finding..i will never use my LG charger if that the cause!!
