Hi,

Just got an answer back from LG. In my email, I was saying that "many users, at international scale, had random reboots/black unresponsive screen issues, and that all our contact attempt lead to an answer like 'not aware, change the phone'" and asking if "now, the problem was known/taking in account/being studied".

The answer was... "update your phone".

...

There is no update available right now (at least in France, the last one was v10b, my black screen accured after that update). But it might mean that an update will come to fix it ? (pure speculation).

No news from the guy who had infos from nvidia or I missed it ?
[LG Optimus 2x] rockerduck:
No more reboots since my hard reset done last thursday at about 4pm.

Only one black screen the same day (but no more).

I reset the phone using power+volume_down.

Then the phone was still rooted

Today I'll change the stock launcher with LauncherPro and install my purchased Beautiful Widgets... and see what happens...
[LG Optimus 2x] kostasalfa:
When i try to check manually for updates ( settings-about phone ) i get an error every time.. no message that your phone is up to date or no updates are available etc..

I get a server connect error , id check failure ?? your phones ok with that ??

Ps.. tell lg that not SOME phone are affected!! If not ALL, maybe a good 80 % or more.. so its not a “small“ issue!!
[LG Optimus 2x] Vertigood:
Just now I noticed one thing..

My battery was at about 70%, then I plugged the phone to the computer with the usbcable to put something on the sdcard.

When I checked the phone just some minutes later the battery was at 36%! A huge drain just by plugging it to the computer?!
[LG Optimus 2x] jivemaster:
My 2x has 38 hours up time... but a reboot always happens... eventually.
[LG Optimus 2x] doncoop:
2more BSODs (black screen of death) while charging last night. Gave up and charged with my ps3 which worked perfectly.
[LG Optimus 2x] TCARMICH:
spoke to LG support and they say this is a general device fault with this model and that I should return it to the retailer as there is no solution at this time and obviously the phone powering down/locking overnight is not fir for purpose....

They did ask me if it was rooted but then said that didn't affect the issue as it affected rooted and pristine devices.

tc
[LG Optimus 2x] 1695:
Yaaaay... -_-

No more infos ? Hard/software issue ? Nothing ?
[LG Optimus 2x] kostasalfa:
We gotta have details here this sounds serious!! If its hardware we should all take em back and get refunds no other units!!!
[LG Optimus 2x] Hannes The Hun:
*IF* it is a general hardware failure, LG will have an official announcement over the next few days. I don't believe anything that some support guy told one poster on a forum, and neither should you.
[LG Optimus 2x] Artemon9:
I have the same id issue,when trying to update my phone.
[LG Optimus 2x] speedx2:
One more here: Got it yesterday, was working fine at the beginning (charged via USB from PC.) Put it onto the LG charger at night, turned off. Could start it normally in the morning. On the next day, things working fine, until I put it on the charger again. Freeze which could be only solved by removing the battery. Later on, tried a call, after finishing the call the phone turned off and I had to remove the battery again to get it back working. So far, no problems under load. Loading from USB/PC seems to be ok.

Interestingly, I also have the 20110218 Baseband which seems to have this issue more often? The rest is as usual.

Did anyone who sent the phone in get a replacement already that works? I'm worried to send it in for a potentially 1 month repair or so if they have no clue on what is going on.

Anyone who knows if the update that is supposed to come out in 2 weeks is addressing this issue? Any confirmation on whether it's a software or hardware issue?

That really sucks, going to contact LG support and send them a link to this forum, so they don't tell me that I'm a single customer with issues.
[LG Optimus 2x] kostasalfa:
You are right man, but the official lg silence is killing me!!

All 2x‘s are affected! ( did go to a huge local dealer and the guys there reported over half of the phones send back!! )

Next few(meaning??) days wont be good for expansys so i can get my money back!!

Allthough i still think its software, as underclocking to 800 mhz helps my device cut down the failures by 70-80% !!
[LG Optimus 2x] CCloak:
My experience is that there is a much higher chance that the phone bsod when it is hot but idling. The phone never bsod even when its hot as long as the screen remains on.
[LG Optimus 2x] jivemaster:
Strange - I've never had heat issues in either scenario. Phone has always felt normal to the touch when picking it up when either happens.
[LG Optimus 2x] speedx2:
I also had it reboot/freeze both when hot and when cold (idle), but never while using it -- temperature does not seem to affect it much. Hot when idle does not seem to increase the failure rate. However, hot when charging means freeze for me (charging from PC works fine usually.)
[LG Optimus 2x] TCARMICH:
Sure, I just called them because it didn't seem anyone had actually got any feedback from LG themselves and it could have been an easy/known fix.

He said they were advising return to retailer as there is no fix right now HW/SW, and if I missed returning in the retailers window of free return (7 days) LG would only be able to take the device for warranty repair, and if it was rooted they would not repair it as the warranty would be voided .... so safest to return it to retailer. As it happens mine isn't rooted but for those that are, beware.
[LG Optimus 2x] .:george:.:
FYI, if you unroot, your warranty is still in play :)
[LG Optimus 2x] ReiskaSeta:
just charced my phone on wallcharcer.. now phone is in bootloop...GJ LG..
[LG Optimus 2x] kencheung2008:
Tested again with another charger.

My non-official charge is 0.2-0.4A &0.5A.

PC USB port is 0.5A.

And LG official chager is 1A as per the label.

maybe it is the cause of "freeze".

"Reboot" could happen anytime, i guess it is the software problem.
[LG Optimus 2x] speedx2:
Also trying a different charger now. 5V and 850mA.

Edit: Loaded over night, no freeze.
[LG Optimus 2x] Artemon9:
I used my Samsung charger again overnight.No freeze or shutdown.
[LG Optimus 2x] hisham2k:
Same here. for no reason at all. shuts down and I have to do a battery pull to reboot.
[LG Optimus 2x] awf:
Have the phone now in use for a few weeks and have since last week randomly reboots during long idle periods (in the early morning)

Have had a few freezes or lockups during idle periods (solutions is to remove the battery)

Working on the lg launcher on a non rooted phone.

Phone isn‘t warm or even hot when the freeze occurred but just had a idle period.

The reboot happens also during idle periods :-(

My son purchased togetter with me the LG-G990 and doesn‘t have the problem at all go figure!

On the edge to return it going to contact LG for my VIP service ...
[LG Optimus 2x] frittenpiekse:
After one week without problems i got issues in the last three days.

first it freezed while in idle (after 5 minutes of waiting the lockscreen showed up but didn't react so that i had to remove battery. next day it rebooted while i was at work and it laid on my desk (idle), after entering my pin i had to restart because sd-card wasn't available. and today i woke up and it was shut down :/

while charging (original charger) i didn't have any issue till now.

Android 2.2.2

Baseband 1035.21_20110218

[LG Optimus 2x] pulsation:
Hello all,

Three days now since shutdowns / reboots didn't occur on my device.

It's impossible to say that there is a magical solution to these problems as several days can pass before they occur again. However, just in case, here is what I did 3 days ago :

* Installed Cpasjuste's tunable kernel and PimpMyCpu (keeping standard frequency and voltage settings)

* As the battery drained very quickly after installing this kernel, tracked background processes with Battery Mix. The standard (non-LG) twitter application drained most of it, so I removed it. However, other application with background services like k9mail or appbrain run well.

* Never shut down the phone while charging ; because before, charging the phone a whole night while it was shut down put it in an inconsistent state several times (had to remove and put back the battery so that it can be powered on again).

* Still using the Samsung charger, or connecting the phone to a computer.

Hope this can help. It's seriously annoying to find your phone shut down in your pocket when you expect a call.

Wish a very nice week end to you all :)
[LG Optimus 2x] blackcmos:
I didnt exerienced this at al, i use this phone now for more than a week and no lagg or reboot at all. i didnt root my phone yet.
[LG Optimus 2x] aco47:
So You have already swapped your LGOX2 at the dealer or what??
[LG Optimus 2x] aco47:
This thread is growing...

Hi all LGOX2 owners,

I had no idea this thread would come to this when i first posted the issue in #1.

I must say i have not experienced the problem since i posted it, but I did talk to LG customer support the other day. The Guy I talked to (offive type service clerk) had not heard of this yet and didn't seam to make a case out of it. Badly. He just requested me to get the phone swapped for a new unit. I will give it some more days before I make up me mind. But of course, if it happened twice, the it will most likely appear again sooner or later.
[LG Optimus 2x] De1v3c1o:
I'll have the same problem.

He rebooting all the time.
[LG Optimus 2x] ULJ:
No reboot problems here at all. Got my O2X yesterday but have been using it every since :D
[LG Optimus 2x] Naadi900:
Yes I have. Used the Dutch VIP service to change the phone for misaligned touch buttons.
[LG Optimus 2x] xmoo:
I withnessed it 2 times just 1 day.

Nothing else.... Never again.....
[LG Optimus 2x] rifmouk:
hello everybody

it seems , it's better if you delete Car Homme App and F secure after rooting

see that

" +1 I recommend you first uninstalling the Car Home app and F-Secure (if you are not using it) because it is highly responsible for freezes and instabilites (AFAIK). "

on this post http://xdaforums.com/showthread.php?t=953182

see you soon
[LG Optimus 2x] Naadi900:
Just had another hang while on the charger. Was just on the charger for maybe 20/30 minutes. Phone was half under the blanket accidentally and very warm... so maybe this was a problem caused by overheating.
[LG Optimus 2x] Novek:
I had two or three random reboots yesterday, after first charge. Phone is rooted, but haven't removed anything that would cause fc...

today I haven't had any reboots, but can't be sure it won't occur again...

but I think it's just a random sw bug, if it was the hardware, or related to the battery or connectors it would act a little different I think....
[LG Optimus 2x] jwedda:
Just another response otherwise it looks like the 2X is bad all over.. ;-))

Had my phone now for 10 days, rooted 30 mins after unboxing.

No reboots yet, but car home and f-secure frozen with TB.. ( as well as the live wallpapers, LG Home and a few others )

Phone is working beautifully.. call quality is suprisingly good.. Skype via 3G/H and wifi is perfect.

((( And OT Only thing that bugs me is the hdmi out.. tried it yesterday but seems like it's showing 480x800 on my 1080P television. Lots of jagged edges when showing recorded 3gp files taped in 1080P. Haven't tried lower bitrate 1080P stuff yet )))
[LG Optimus 2x] bryant_16:
That's bad. Hopefully the majority of 2x users are fine.

Certainly I would have to think twice before getting it.
[LG Optimus 2x] ULJ:
Well, the amount of phones that are produced are huge so there will always be some that are affected by faults/errors - mostly hardware. Take the Nexus One/HTC Desire with the faulty power button, same goes for the Nokia N8. Apple with yellow bubbles behind the screen. All manufacturers produces phones with faults - thats just how it is.

My O2X functions perfectly - both hardware and software wise.
[LG Optimus 2x] Naadi900:
Crap, just now had a reboot while charging...

left it on the charger, started up. 5 minutes later the phone is frozen, no ADB available, only way to bring back to life is by pulling the battery.. Gonna call with LG about this..
[LG Optimus 2x] maedox:
You are all reporting issues, but none of you have said anything about software version numbers, baseband version etc. Don't you think that is essential for other reading this thread?
[LG Optimus 2x] Naadi900:
Maybe that is indeed essential.. haha.

[LG Optimus 2x] bryant_16:
So many instances of phones rebooting?? That's bad..
[LG Optimus 2x] kencheung2008:
:) Thus, I would like to conclude,

to avoid freezing, use charger with 0.5A or lower,

although the charger process takes longer.

Auto-reboot, seldom occurs with Paul's custom rom.:)
[LG Optimus 2x] speedx2:
Hm, did a software reset (i.e. reset to factory defaults) and charged with a 0.8A charger, and no freeze/reboot so far.
[LG Optimus 2x] reidar.ostrem:
I'm using both my HTC Desire charger 1A and LG Original charger.. I do not have problem with reboots and freezing.. (Just to add to the confusion :))
[LG Optimus 2x] kostasalfa:
Lets hope lg responds tommorow..I ve read in an optimus 2x forum that the issue is froyo,and will all be fixed with the gingerbread update that will rushed out faster due to this. But all this might still be speculation..

Anyone with no freezes??( still ! ) What baseband is more bug friendly?
[LG Optimus 2x] Cronner:
Can confirm random reboot on unrooted phone and rooted phone :( both phones does this
[LG Optimus 2x] speedx2:
What forum? I‘m also hoping that its software only, especially as the pre-release devices had similar issues (see for instance the engadget test.) I seriously doubt they gave faulty hardware to journalists and blamed the software.
[LG Optimus 2x] kostasalfa:
It so worrying that they didnt fix it by then..all reviewers saw those problems and though thatvprerelease software is to blame for..i think i read that in optimus2x.net..

Also worries me that there is still no media attension!! No google responce!!

HAVE HAD SOME I FANBOYS LAUGHING AT ME..AND THEY WERE RIGHT!!!

THE ADVERTIZED AS FASTEST ANDROID PHONE OUT TODAY CANT STAY ON FOR THREE HOURS!!

This is not a bug is a big joke to all of us who did go and PREorder those lgs.. Should have heard and waited for gs2..

Last hopes for tomorow its too long since the phone its out with no official responce..
[LG Optimus 2x] thatguychris:
I've also had this problem twice now had the phone a week also had the lockscreen lag and very concerned about the battery drain issues, when is the update due and do we need to use the LG update tool?
[LG Optimus 2x] kostasalfa:
Lets hope it stays that way with your phone.. ( dont want to be the messenger of some bad news but guys in the thread had not ANY problem for like 9-10 days and then it started to them also )

Btw, whats your phone info??

( mine just fell in a ..constant bootloop, last two days its almost unsuable.. )
[LG Optimus 2x] jivemaster:
We did a factory reset and had 50 hours uptime over the weekend, then it rebooted and froze the next day. A factory reset will not fix things.

And screw ups while charging is just a coincidence imho - ours only ever did it once while connected to a charger, every other reboot and black out happened while idle. We've had ours for 10 days.
[LG Optimus 2x] xmoo:
My Max was 119 uptime hour.
[LG Optimus 2x] reidar.ostrem:
Well, my phone is 25th days old :-)

Right now running Mcr Fr10, and using the 0315 baseband.
[LG Optimus 2x] bryant_16:
Don't know what's wrong with my phone. Just couldn't pass the 38th hour up time mark. Always after that, the phone will just hang by itself, and I need to battery pull it to restart the phone.

Any help guys?
[LG Optimus 2x] ericc191:
This makes me really uneasy about buying the G2X..
[LG Optimus 2x] jivemaster:
You're almost better off powering off and on the phone each day to reduce the chance of needing a battery pull.

Dude that's epic. We have never got near that.

You would hope the g2x, having a different rom altogether, would be far less likely to have these issues.
[LG Optimus 2x] jtroye32:
Yes, let's hope vanilla android will fix all this.
[LG Optimus 2x] ericc191:
I was pretty pissed at HTC for the G2, so I'm hoping LG comes through with a working G2X and a fix for the O2X.
[LG Optimus 2x] speedx2:
I was just told by a LG support guy (LG live chat)

* Phone rebooting/freezing: First question was what SIM card I have, and that I should put in a 1.8V SIM card.

* Freezing while charging: If the charger freezes the phone regularly, then it's a hardware defect.

I have a 3V SIM card, trying to get a 1.8V SIM card and see if things get better.
[LG Optimus 2x] djmcnz:
Well, I just got another frozen phone when I got up in the morning but it was not off... after much playing around with adb, which kept timing out, I got the following log:

http://pastebin.com/wrhVFzeF

Hopefully it helps somewhere along the line but I suspect this is the major cause, it's repeated throughout the log:

I/ActivityManager( 1114): Low Memory: No more background processes.

Which results in all sorts of problems...

I/ActivityManager( 1114): Low Memory: No more background processes.
I/ActivityManager( 1114): Process android.process.acore (pid 28471) has died.
I/ActivityManager( 1114): Start proc android.process.acore for restart android.process.acore: pid=28514 uid=10001 gids={3003, 1015, 4002}
I/ActivityManager( 1114): Low Memory: No more background processes.
I/ActivityManager( 1114): Process android.process.acore (pid 28559) has died.
I/ActivityManager( 1114): Start proc android.process.acore for restart android.process.acore: pid=28571 uid=10001 gids={3003, 1015, 4002}
I/ActivityManager( 1114): Low Memory: No more background processes.

Which indicates to me the system is just chasing it's own tail...
[LG Optimus 2x] pulsation:
Sure... :/ Honestly, I bought the o2x just because it was quite cheap and should have been good performance hardware for more than on year. When people started talking about shutdowns, I hoped to be lucky and get a correctly working device, or that these problems would be solved by a firmware update. But either haven't been the case yet :p

Are these problems hardware or software? If they are hardware, will there be workarounds? Would it be possible do diagnose it, as the device may work as expected for days when returned back to the after sales service?

So, maybe the good choice would be to wait for LG's official position about these problems and if they can be solved, or strictly diagnosed so that we can return the faulty phones back.

If you're patient enough, it's still possible to wait for a working official or unofficial firmware that would workaround them without any performance loss. But as time passes by, other manufacturers may produce devices that work better.
[LG Optimus 2x] bryant_16:
I have rooted and froze car home app and f-secure app.

Will the above help in the reboot problem?
[LG Optimus 2x] 1695:
That's pretty interesting ! You should make sure Paul from MoDaCo sees it, or any good dev. It doesn't show the cause, but might help someone to figure it out ?

At my level, that make me think of software more than hardware...
[LG Optimus 2x] professor78:
Well for me I was having shutdown or reboots neraly every time I charged.

What has fixed it, and now have 83hrs uptime was :

Putting pattern screen lock on + Stay awake while charging.

But now I have another problem... When the phone is asleep it seems to turn off wifi connection, when i first turn it on you can see teh icon change from 3g/H to the wifi connection symbol.

I know its an issue as I have used 90mb of data while being at home all weekend and wifi has not been down!!!

Only get 500!!!!
[LG Optimus 2x] bryant_16:
Impressive uptime. Can I check with you if you are rooted?
[LG Optimus 2x] :
I have had one reboot and one freeze in the first two days. Now, I have the phone on since the 8th without any problem.

Meanwhile, and as I've complained to LG in the first days, i've received a phone call from LG informing that they could pick up the phone and send it to repair! I've told them that for now it's working and that sending it to repair was something I didn't like that much due to some reports on people changing phones and the new ones having the same problem! The guy on the phone was very nice and told me that if the problem happens again, I should contact them that they will pick up the phone and send it to repair without any transport costs from my side.

Let's see how it handles in the next days.

Check your WiFi settings. Go to Settings->Wi-Fi->Wi-Fi definitions and press the menu button and chose Advanced. You will see a Wi-Fi policy settings there with 3 options. I have mine to "Never", meaning that wi-fi never turns off. Maybe the option names are not the correct ones, but I don't have my phone in english.

Mike
[LG Optimus 2x] bryant_16:
Great! Is yours rooted?
[LG Optimus 2x] kostasalfa:
This is not a bug my friend.go to settings,wireless networks,wifi,wifi settings..then there press the menu button and then select advanced.. there change the wifi sleep policy to never!

Seems likevpauls rom so far has less frequent problems..will wait to check uptime..
[LG Optimus 2x] professor78:
Stock build...for now :)
[LG Optimus 2x] professor78:
Thanks for replies on wifi, got it now.

It would probably have been best to have the never as default! And I didn't even think about looking for more advanced options in that screen!

Cheers :)
[LG Optimus 2x] bryant_16:
Good for you!

Mine doesn't shutdown during charging but after the 40th hour mark, the phone starts to act weird and a battery pull is needed.
[LG Optimus 2x] :
Rooted, with latest baseband, but still with stock rom.

Mike
[LG Optimus 2x] bryant_16:
I see. Did you freeze applications like Car Home and F-Secure?

Where to get the latest baseband?

Before rooted, you got the restart problems all that?

Sorry for the numerous questions..
[LG Optimus 2x] :
Yes, they were freezed after I've rooted the phone.

Here

The only restart and freeze I've had were after root. The reboot I was when I was downloading some new apk and starting Angry Birds. For the freeze, the phone was on the table and 1/2 hour later when I pick it up, it was dead!

Pay me a beer one of this days :D.

Mike
[LG Optimus 2x] bryant_16:
But I'm glad that it is working fine after that. Somehow I couldn't get through the 40th hour mark so I rooted and froze car home and f-secure, hoping that it would improve on the issues.
[LG Optimus 2x] TCARMICH:
I also tried a USB travel charger which is 0.5, ad a Blackberry charger and no difference I wake up in the morning to a dead device which can only be restarted by removing battery. This morning I found the battery was completely drained having left it to charge from 55% last night.

This is definitely not usable!
[LG Optimus 2x] d3n1s:
Hello, I found after reading many forums on this reboot problem that Angry birds is often cited. I have an LG optimus for 1 week and I have reboot problems since two days since I installed angry birds! I do not know if there is a link, but Have you installed angry birds ?
