[LG Optimus 2x] rambell:
I had the phone for 2 weeks now, never had an issue with it until it suddenly shuts off yesterday and rebooted itself. Not too sure what to make of it, most likely if it doesn't occur again, it should be working fine. I think.
[LG Optimus 2x] awf:
Well my first one was fine the first 3 weeks after that a horror story...
[LG Optimus 2x] rambell:
Oh well, it rebooted again today. It's been uplugged for over 60 hours, not sure if that's a factor.
[LG Optimus 2x] Wwax:
More and more convinced that most of the problems is due to heat, not because it gets very hot but the saftey treshold is set waaaay to low.
[LG Optimus 2x] geistio:
I just experienced another "sleep of death" on the latest CM7 build.

Luckily I could connect via adb and do a "logcat".

This is what I got:

pastebin.com/prGFPNMt

(I cannot post links yet... sorry!)

This is the output from "dmesg":

pastebin.com/ARJS66K1

And this from "ps":

pastebin.com/jhvXC9ui

At least to me it seems that that "system_server" somehow crashes and effectively turns down the whole system.

Maybe we should get this pastebin-link to the CM7 developers?!

Any volunteers? :)

Dont own Optimus 2x, but the owner of Tegra 2 Tablet(Toshiba Folio 100). Watching this thread cause wnt to buy Tegra 2 phone due to performance gain...

My vote goes for Tegra 2 raw & ****ty drivers, Imho they do cause Tegra 2 devices to hang in the middle of nowhere.....SoD is also a syphtome
[LG Optimus 2x] xmoo:
I think it may be a hardware issue. Went to the local phone shop here, and the O2X they has. Had a uptime of 240hours!!! So no SOD or reboots... Was running 10A tho
[LG Optimus 2x] zorgl:
mine seems more stable since i no longer use 'advanced task killer'

i still had one freeze, but no more i'm-dead-please-remove-my-battery.

rem: i also charge it via the usb, not the charger, will try the charger again...
[LG Optimus 2x] kostasalfa:
Disabling autokill on screen off helped me with reboots too
[LG Optimus 2x] r1si:
don't use task manager !
[LG Optimus 2x] awf:
Well my impression is that the freeze issue (battery pull) is software related (some software invoke an old out of memory issue (or memory leak))

Which explains also the lag and the phone becomes unresponsive ;-)

Try a reboot before the phone has the lag and very slow unresponsive symptoms...

Have to find time to start a process log file :rolleyes:

Despited the fact we have here an second O2X running 8+ weeks now and uptime 320 hours without any problems.

The spontaneous or wall charger reboots are most likely hardware just go for a replacement :o

Up until now had one freeze with the replacement O2X which I probably can pinpoint to other software (have to test more)...

No spontaneous reboots anymore, but there is always a but lol

Have to test more because I'm very cautious with this phone to conclude anything with a almost two weeks replacement old O2X...

I prefer a Gingerbread update without any LG software :eek:
[LG Optimus 2x] ozivillan:
mine seemed quite stable for about a week, this was after i made arangments for it to go back for replacement or a credit, last couple of days it has started freezing and rebooting again, have stated on my returns form that i do not want it repaired as i don't think something can be repaired if they don't know what the problems are with it, not happy with the situation, costing me nearly $100 to return the phone, if they replace the phone and it still has problems then i think i will just relagate it to the bedroom to be used as my alarm clock , oh hang on can't do that either as it seems to have trouble in that department too :eek:
[LG Optimus 2x] mohicanrat:
my 2x cannot have this problem. because i always charge with optimus one charger.

i know charget 2x have something wrong.
[LG Optimus 2x] pulsation:
Well... it would be useless even as an alarm clock if your phone freezes randomly, wouldn't it?
[LG Optimus 2x] Andy_Satriani:
yup, im using my sister's blackberry charger and it doesn't hang anymore. hopefully it stays that way
[LG Optimus 2x] waynefox:
Mine just shut down again. Battery was at 51%

put it on charge in the car. When i got home, it was off. Switched it on again and battery was at 1% and it powered off again due to low battery.

The phone was quite warm though from charging in the car
[LG Optimus 2x] Pfeffa-rah:
Had the same problem.

After I deleted (renamed) F-secure and CarHome it didnot happen again.

After I updated to the new baseband it started again and this time it was much worse.

I used the VIP service and they swapped my device within 24 hours as promised.

The new phone is much snappier then the old one, even with all programms reinstalled. I got the new one 3 days ago.

However,

This afternoon when I switched it on, it asked for my PIN (simcard unlock) so I am afraid it rebooted again... :(

Am I correct is thinking so?

Phone IS rooted.

No apps removed/frozen (yet)

Baseband: 1035.21_20110405

Kernel: 2.6.32.9

hello,

wanna buy LG optimus 2x.. so.. is this problem solved or not? I can get Optimus 2x or desire s.. but think that desire s is just a make up... nothing new inside 1 year old desire
[LG Optimus 2x] felixthecat:
sim lock

mine does not seem to restart or freeze but (and this happeded to me whilst using it ) quite often I need to unlock the sim. This was not after a restart. There was no LG logo or sound when it happened. Quite often I come back to my pone and it is asking for sim lock code. but as sooon as i enter it it is back wehere it was eg brouser. Is this the same issue as others ?????????/??????????????????????????????????????????????????????????????????????????????????????????????
[LG Optimus 2x] bryant_16:
Hey guys,

Just an update. Previously, my phone stock or non-stock rom is always having the random freeze where I need to pull my battery to continue using it. The phone couldn't go through the 40-45 hours of uptime before it will freeze.

So I bring it back to the service centre to let them have a look. After 1 week, I collect back my phone and they told me that the camera unit of my phone is faulty and they have replaced it with a new one and up till now I'm having 80+ hours of uptime.

I have tried previously to use different charger but to no avail. So it might not be due to the software but the hardware of this phone which is such a pity.

That's all. Hope this information help you guys.
[LG Optimus 2x] jivemaster:
I cannot see how the camera would have any relation to the reboots. It's shoddy software plain and simple.

Of those that haven't had the reboots, the vast majority have been running custom roms or at least have root and removed some of the bloatware.

This reboot thing seems common to other tegra devices, which could mean some of the tegra drivers or parts of the kernel are rubbish and cause reboots.
[LG Optimus 2x] bryant_16:
I don't know too but at least this is what he told me. He mentioned about the wrong voltage or whatsoever in the camera that resulted in the random freezes.

Take it with a pinch of salt.
[LG Optimus 2x] xromx:
Hello. Im a new owner of P990 2X since May 6. I had no problem until yesterday when I tried to charge the phone with the stock charger. After 20 minutes, I heard a beep on the phone and I thought it was an incoming mail. But it really was a restart an the screen showed a pin request. I entered the pin but 1 minute later, it restarts again. After the fourth restart, I unplugged the charger and I noticed the phone was really hot. With no charger attached the phone shut off and I had to take the battery out (It was still hot).

I waited to the phone reached normal temperature and I charged it with the USB cord and no problem (the temperature was OK).

Since then I have no problem but I dont know if its normal that the phone gets so hot while plugged with the stock charger.

I tested the voltage from the charger and it reads 4.8 V. It seems normal to me.
[LG Optimus 2x] Denonite:
Just wanted to share something I discovered over the last few days.

My phone only shuts off/freezes (requiring battery pull) when I leave it to go to sleep. (under CM7.11 Nightly and all previous versions)

If I finish using the phone and press the power button the phone can last all day without freezing but leaving it to sleep itself will result in a freeze two out of three times and it happens quite quickly.

So this instance may be something with or voltages dropping too low when the phone automatically gradually sleeps after use rather than when the power button is pressed to force it off.
[LG Optimus 2x] PERSONA:
I have a similar observation, that it would hang when it enter sleep mode. However, even I press power button manually such that the phone went to sleep mode, after waiting for some time, it would still hang.

But as long as I don't let the phone went to sleep mode, the phone is working fine.
[LG Optimus 2x] charleybrown_de:
This is exactly my observation as well! Then, when you notice that the phone is dead and pull the battery the battery level will have dropped a lot! For example, if you realize after about 30-45 minutes that your phone is dead and pull the battery to restart it, the battery level will be about 15-20% lower than before the freeze. Much more than what is usually consumed in the same time. So the phone does not seem to be really dead but rather doing something that consumes a lot of power...
[LG Optimus 2x] doncoop:
I have the feeling that it has happened to me when I have locked the phone I'm afraid.

However agree with the battery % dropping (just did it to me went from 50% down to 21%).

Here is something though. Had no network signal for 20 mins prior to the BSOD. We all know that the cell standby is waaaay too high, perhaps its trying to network connect in some way. I cannot profess to reading the manual but people have commented on sometimes seeing E used.....surely you have 2G or 3G and nothing else (in the UK) so what is the E for?

Just ramblings of the disgruntled
[LG Optimus 2x] charleybrown_de:
The "E" is for EDGE, a kind of enhanced 2G. It's faster than GPRS but slower than UMTS or HSDPA (3G). See here: http://en.wikipedia.org/wiki/Enhanced_Data_Rates_for_GSM_Evolution
[LG Optimus 2x] awf:
No it's not normal and that is the hardware issue go for a replacement ;-)
[LG Optimus 2x] tdci100:
Got my 2nd replacement today.

This one was replaced over VIP service (service available in NL and Belgium).

Not sure it's a refurbished unit, but it came as phone body only in a plain white box with a sticker and its IMEI number.

The phone is supposedly coming from the Netherlands according to the company in charge of the exchange. Default language was dutch at boot.

Anyway, it was a V10a and 20110223 baseband, exact same version as my two previous units at first boot.

Upgraded to V10b and 20110405 with LG Update Tool.

Will test stock ROM for a day or two then move to custom ROM.

I'll let you know if I have any problem with this 3rd unit. If I'm having issues, I'll request a refund.
[LG Optimus 2x] LickMyEar:
All, please leave some feedback here http://www.facebook.com/lgmobileaus so LG can do something about it. We have strict laws in Australia and if they cannot fix this problem, they cannot release the phone here.
[LG Optimus 2x] blackcmos:
Updated to 10b last week, no probs at al till now no reboots,( none i noticed) on 3g i get a full 34 hours on one battery, i dont know why some users of the 2x are having so much troubles! Maybe it will be better at the stock 2.3 gingerbread :)
[LG Optimus 2x] awf:
Update 14:

My first O2X replacement is behaving (VIP service) as it should be no problems anymore (had one freeze which was caused by software one week ago)

3 weeks now updated to V10B the moment I received the unit (running stock non root).

battery/charger/USB cable/cover aren't replaced so the reboots (and spontaneous reboots) was due to heat generated by the unit.

This one generates a lot less heat and finally stable still cautious but it looks promising :-)
[LG Optimus 2x] Denonite:
Further testing and a day of woe today. Many freezes but one further observation.

It's only freezing with the battery below roughly 75%. Above 75% battery all is good.

I can't hack it behaving like this so it's back to Pauls FR15 release (did a back up before going to CM7).

This is why it looks like a software issue to me. My phone was fine on stock, fine on 2.2 FRXX releases and I only get freezes on CM7.

At least I'll have a fully configured CM7 back up for when they fix it.
[LG Optimus 2x] walkerx:
since i've been on this replacement phone and upped it to 10D I've not had one freeze or reboot so far in just over 2 weeks.

One thing I have not done is started the F-Secure AV software which I had done on my other phone
[LG Optimus 2x] tdci100:
Got my 3rd unit monday.

No problem at all on tuesday on stock rom.

Installed latest Cyanogen last night. BSOD after unplugging from USB.

This morning, BSOD around 1 hour after unplugging.

Now back on Modaco Vanilla Fr12.. will see how it goes.

The 3 units I got are all coming from the Netherlands.
[LG Optimus 2x] choccy31:
My phone came with version 10b when I got it and have these issues.

LG have released a new update to V10D now.

Gonna try it tonight when I get home.
[LG Optimus 2x] biasquez:
your phone is european or italian version? i'm italian and i have firmware v10b but when i try to update it, lg mobile update doesn't see v10d...
[LG Optimus 2x] awf:
Same here :-)
[LG Optimus 2x] choccy31:
I'm in the UK.

Does anyone know if you can deactivate the Security App?

If so I might give that a try for a few days and see if the same issue occurs.
[LG Optimus 2x] Ben86:
My LGP990 history:

-Got the Phone on 2. of April

-From day 3 i have had lots of problems (wont wake up from standby, no network, reboots and so on)

- sent it to w-support and got back without a repair but some scratches

- got a replace from amazon and yeah it worked for some days

- now i got the same **** again

anyone who changed from LGP990 to SGS2 and want to report how it is?

I recognized one interesting thing. With the first decive i used the hdmi out pretty early and like i just wrote i got the problems pretty early.

some days ago i used hdmi out with the second device. until this the device worked fine, just some lags. But since i connected hdmi on it the lgp990 get real bad. i wouldnt call it a phone anymore because i cant even have a call without the fear it will break the call
[LG Optimus 2x] theonlyq:
I have V10d version and it asks for PIN from time to time. I don't know if it reboots or just the modem service crashes, but what I can tell is that it overheats around the camera and the battery drains (for example it happened once to go from 80% to 17%). I don't know if it's related, but since I've uninstalled the automatic task killer, it got better.
[LG Optimus 2x] choccy31:
I have contacted BBC News tonight as maybe they can run story on the tech page?

Maybe if others emailed them too, they will be more willing to run it.

I copied the link to this http://www.trustedreviews.com/news/lg-optimus-2x-suffering-freeze-and-reboot-problem

[LG Optimus 2x] Pfeffa-rah:
I might have fixed mine... not sure yet....

I got a new phone via the dutch VIP service, but this one started rebooting the 2nd day allready. Also my battery was always verry warm/hot and would barely last a full day.

So... three days ago I tried EVERYTHING I could think of that might cause any problems.

1. Installed Clockwork Orange Mod Recovery to make backup.

2. Use Clockwork Orange Mod to format my 32GB SD card.

3. Flash Paulobriens Stock Performance Pack (http://xdaforums.com/showthread.php?t=1027291)

This took me a few hours. It started behaving verry funny. (E.G. battery 42 deg.C. but it would show 92% the whole day...)

So I rebooted and since then, it works like a charm!

No battery drain when not in use

Fast

Stable

offcource, it's just been 3 days and the reboots and shutdowns only happened to me 3 or 4 times a week....

So I'll just keep my fingers crossed.

I'll let you all know if/when it starts rebooting. (throught update here and a new message.)

grtz,

Pfeffa-rah

update: Today it shut of and I hed to remove and replace the battery. It wad not on a charger but just in the pouch, not doing anything.

I'll call the VIP service again and let them swap my phone around for the 2nd time. This time I'll tel them to also bring another battery.

:(
[LG Optimus 2x] BURNEE:
Well, I see a lot of you complain but has anyone actually tried this kernel http://xdaforums.com/showpost.php?p=12789611&postcount=1 ?

It's probably not the most stable or reliable kernel but if it fixes the problem then we have nothing to worry about?

Happened to me for the first time today while charging via USB from my work computer. It just rebooted at a 100% charge? WTF?

[LG Optimus 2x] IPdaily:
Hi, i‘m new here and to android devices, so thought i would share my exerience, especially after reading so much on here about all the issues. My phone is stock, unrooted, uk v10b.

I thought i was lucky with my phone - had it for almost a month and a half and after a week or so the battery lasted me full day with pretty heavy use (for me at least, i love the phone and still can stop picking it up every 10min to check fb/go online/play games/constant wifi on etc, with quite a few texts a some phone calls, take off charge at 6:30ish am and plug it in at 10pm with ~20% still left), the phone only shut down on me twice till today with only one or two re-boots until a week ago. But since then it reboots every day once, mostly in the mornings when i unplug it (coincidence or not, but worth mentioning, because if it‘s not, it might suggest hardware issue and not software, probably a rubbish component, i‘m not an extert though, this is an educational guess).

So anyway, like so many on here, i am not happy. I signed the petition and hopefully lg will gat the message and address the fault.

Cheers

Is just a fu**ing copy / paste of an old article is not true :mad:
[LG Optimus 2x] IPdaily:
A pure guess, and apologies if already covered elsewhere, but has anybody considered that the problem might be with nvidia drivers, there might be a bug that causes a memory leak or something which might cause a reboot or shut down. I have nothing to back this up with, this is simply a speculative comment. Might be worth checking if hasn‘t been yet.

[LG Optimus 2x] thomasdr:
So I got this phone since tuesday, it's my first smartphone and so far I've had 2 freezes. Twice after heavy usage when my battery temperature is pretty high and I tried to charge it again.

Battery life seems low, and does some weird stuff. Yesterday it was at 100% at 2pm and it was at 0% at 8pm or so it indicated. the last 20% were lost on standby within an hour, the phone was pretty hot 32-35 C° for doing nothing.

Anyways, an hour later I tried to boot him again and my battery was back at 18% lasting another 4 hours on standby.

Anyways, after 30mins of playing games my battery reaches temperatures of 45° and on standby around 27°. Don't know if this is normal because I've never owned a smartphone before.

Should I be getting a new one if it continues freezing or doesnt it solve anything?

Then, sorry to have posted it :( I didn't know that. :(
[LG Optimus 2x] awf:
Update guys I'm going to call tomorrow and for the first time I'm really mad had the first spontaneous reboot on the replacement phone (second one) was dead had to restart with pin...

I hate this one and going for a refund... :mad::mad::mad::mad:
[LG Optimus 2x] kchakkar:
I have had my phone for 2 weeks now and have had no re-boots. Even when using my phone in hot weather - the back got a little warm but no-reboot. Used GPS alot which works great no problems locking to signals. Tried lots of games and no freezing or re-boots.

The only problems I have is poor battery life and signal loss sometimes when inside a car i.e switches to 3g- then 2.5g then loses signal for 2 seconds then connects again. Also sometimes the menu lags - but I assume this is because of Froyo 2.2 and will be corrected in 2.4 or 3.1.

I think I am one of the lucky one:D
[LG Optimus 2x] awf:
Well I wouldn't spoil your enthusiastic experience, but both my phones (first + replacement) where the first three weeks fine hence even with a uptime of 160 + hours but then :eek:
[LG Optimus 2x] tdci100:
I've got the same feeling. I posted this idea a while back in this post.

You know how some laptops never wake up from sleep on Linux ? Usually due to poorly implemented drivers.. I have the feeling this is exactly the same problem on our phones.

Look, how could it be hardware related while my unit BSOD like crazy on CM7 and have 48 hr uptime on Fr12 vanilla ?
[LG Optimus 2x] tdci100:
Have you installed anything particular lately ? Or absolutely same condition and 3 weeks fine then it starts BSOD'ing out of nowhere ?
[LG Optimus 2x] xmoo:
So we need to warn LG that there doing a awesomejob, but nvidia isn't? :P
[LG Optimus 2x] awf:
Thanks, but the first one had heat issues (became really hot during wall charge) and all the other issues too , this one I keep also pristine (non rooted phone) to rule out any stuff and as an IT guy the first thing I check is what maybe has changed...

Normally if it's hardware it doesn't has to occur directly, but most of the time in the first few weeks (this holds for all electronics in general ;-)) symptoms will occur.

Noticed when the uptime goes up at some point there is a dip in memory usage almost starvation (memory leak behavior)

First symptom was one week ago a BSOD and now a spontaneous shut down :(

Amazing how instable this one is and the lag issue...

Frustrating to spent this much time on several O2X phones (when it's stable and no lag I really like the phone)
[LG Optimus 2x] IPdaily:
That‘s not what i am saying at all. It seems everyone is looking for a problem in the same place and the drivers could be part of the problem, not necessarily the cause. Everyone, including me, is so excited about tegra2 that nobody seems to step back and check whether nvidia has delivered on all levels here, wouldn‘t be the first time drivers caused problems like that.

Ps:i am an nvidia fan and am not bigging lg up, we might just need to look at a bigger picture to find the solution

Update - what update?

Hi guys,

I too have just started to suffer the random shut downs - 2 weeks after getting the phone.

I read about an update out today. I run over to LG's support site install the [terrible] update software.

Guess what? No update for my phone (it is not network locked) so I am still on the buggy V10d.

I have a standard install of the OS and no additional applications above and beyond the Opera mobile. Battery life is a joke unless I select 2G only option.

Thanks

P.S. - On another note has anyone got any plans to visit LG on their tour in the UK? I can't post the link as I'm new but search a well known search engine for 'lg mobile 2x tour westfield' and you'll get the link. Might be a good chance to get some publicity to the problems.
