[LG Optimus 3D] botson71:
Perhaps the cause of the problem is the same (baseband crash followed by RIP) but the result is different. On GB you have ghost calls, on Froyo you don't. Let me put it simply:

- On Gingerbread: When someone calls you, he hears the ringing tone and after a while the ringing stops without any message from the network operator that the O3D can't be reached or without any call forwarding to the voicemail.

- On Froyo: When someone calls you, he hears a message from the network operator that the O3D can't be reached or his call gets forwarded to the voicemail. (based on what dsmboost said)

So on Gingerbread you have a "ghost call" (neither the caller nor the O3D owner are aware of the missed call) while on Froyo you don't (the caller is aware that you can't be reached and/or he leaves a message on the voice mail. And the receiver is aware of the missed call since he gets a message on the voicemail).

And don't take my experience for granted. Hundreds of people here have reported ghost calls on Gingerbread but only three people (here, here and here) have reported a RIP event (but no ghost calls) on Froyo.

I suspect that this is because on Froyo, in case of a baseband crash the RIP process fast and the phone recovers much faster than on GB (especially the older versions like 21A... the recent versions like 21D are recovering faster).
[LG Optimus 3D] TylDurden:
I never had any issues on Froyo. I had plenty of "Ghost Calls" on GB where I could see the person calling me, when I tried to answer the screen just froze and a few seconds later I would try calling them back and the RIP message would appear, meanwhile they were trying to call me back getting no response at all.
[LG Optimus 3D] nanodigit:
Is this a ghost call?

Is this a ghost call?

On GB I got a behavior where an sms pops up only when an sms app is opened. The timestamp for the message is usually equals to the time the sms app was opened. Meanwhile this message could have been sent an hour or so earlier.

Today, I got this behavior on Froyo! But never missed a call though. I'm still going to stay Froyo.
[LG Optimus 3D] dreccon:
I don't know why but this question has been spinning in my mind these last few days. GoLauncher has a built-in task manager/killer. Perhaps it is killing an essential system process that misbehaves. So let me ask again. Is there anybody here who has experienced a ghost call and does NOT use GoLauncher?
[LG Optimus 3D] botson71:
I never used Go launcher on O3D, only the default and Zeam launcher.

Also if I remember correctly, the task killer of Go launcher wasn't built-in but a separate app/widget. Did that change recently?
[LG Optimus 3D] dreccon:
OK, so Go Launcher is not to blame. It also seems I'm wrong about the task killer being built-in. Thanks for clearing this up.
[LG Optimus 3D] ThiaiZ:
A lot of people.

I am bored of checking this topic every single day for a new rom. What about you guys?
[LG Optimus 3D] dromico:
me too :( but I like the display of my optimus 3d and I like video and photo functions of my optimus 3d , I feel like following a girl with no chance with her... it's stupid but I can't stop...

Maybe I need a psychoanalyst, but a good one...
[LG Optimus 3D] vpamir:
same here.
[LG Optimus 3D] dreccon:
First ghost call after one month with a new mainboard. My phone is going back to service.

I don't know if this is coincidence but one day before the ghost call I had flashed the DNA 2.0 ROM via CWM. I'm not saying that the ROM is to blame but flashing itself does something to our phone. How else can anyone explain that I never had a single ghost call (or RIP message or battery drain or any glitch for that matter) for a whole month as long as mu mainboard came with preinstalled Gingerbread?

You may argue that CWM doesn't touch the baseband. True! It may just be coincidence. I just felt like mentioning it.

As far as cool_recep's boredom, I totally agree. That's why I'm going to give up on the 3D functions for now and ask LG for a full refund or a replacement with another model that is ghost-call free.
[LG Optimus 3D] cool_recep:
Maybe some of us have broken down the baseband while flashing it. But what about others who have updated their phone via offical ways like FOTA and Phone Update tool?

By the way, go to youtube and search for Optimus 3D videos. I have spammed every single video with ghost call comment. Please thumps up so everyone can see..
[LG Optimus 3D] dsmboost:
The 2nd time my friend called me, he said it rang like normal a few times and then went to voicemail. No errors. He thought the call was going through like normal.

Either way though, it's unacceptable and makes the "phone" feature of this device useless.
[LG Optimus 3D] botson71:
I think that flashing is not responsible for causing ghost calls because as many people have reported here, they are experiencing ghost calls w/o any flashing/rooting/CWM/custom ROM but just upgrading to GB with the LG official tools.

However, even if there is a slight possibility that flashing is responsible, this probably has nothing to do with the hardware but only with the software, namely the poor implemented Gingerbread on O3D. Because the same flashing/rooting/CWM/custom ROM don't cause ghost calls at the same phone when Froyo is installed instead of GB.
[LG Optimus 3D] panzeraggro:
hello guys, after switched back to froyo and v10d bb, I still not have issues with gc <3 . I have 1 question : do I always have to stay in only 2g mode or may I switch on 3g safely?
[LG Optimus 3D] dreccon:
Obviously, the phone uses some kind of low-level firmware in order to flash the EPROM. If the bug is there,or even in the EPROM itself, it won't matter weather we use official or unofficial tools or if the ROM is stock or not. I can't explain why the bug affects only Gingerbread. All I know is I used Gingerbread without problems before flashing and Gingerbread with ghost calls after flashing via CWM (that is without touching the baseband).

Anyway, it's probably pointless to argue. This bug is very elusive. Now that O3D-Max is out, since the hardware is almost identical, let's see if we can get a working port for our device.
[LG Optimus 3D] Magic_Knight:
Froyo doesn't have GC issues at all, so you can safely use both 2G and 3G mode.
[LG Optimus 3D] superage:
I have No Ghost Call - Tested > 500 calls.

Hi

I do not know if this post useful or not but I was very interesting to do the test myself.

My O3D running stock rom GB 2.3.5

Baseband L6260_MODEM_SIC_01.1042.00

Kernel 2.6.35.7+

Build Number GRJ90

Firmware V21a Nov-15-2011

I bought this phone about 2 weeks ago from ELGIGANTEN store, Kungsgatan, Stockholm.

I did upgrade to GB using LG mobile support tools.

Rooted using Super One Click 2.3.3

Installed CWM from ROM Manager

I used system tuner to disabled start-up for many apps. I keep only the important apps.

I manage to have free RAM > 220 MB.

I did call test for 3 days (24-26 April) from my O2X and Galaxy Tab 7.7 to my O3D.

O3D Battery Level > 90%

Day 1#: ~75 calls in 2G, ~75 calls in 3G

Day 2#: ~100 calls in 2G, ~100 calls in 3G

Day 3#: ~100 calls in 2G, ~100 calls in 3G

My O2X roam in Telia. Numbers from Indonesia (Operator Telkomsel)

My Galaxy TAB 7.7, Telia Sweden Number.

My O3D, Telia Sweden Number.

And the result was good. I never have a ghost call. All the calls successful and my O3D always ringing.

I may do more tests with different condition.

1. Test when RAM < 100 MB and Battery > 90%

2. Test when RAM < 100 MB and Battery < 15%

If some of you know how I can reach the free RAM < 100 MB, please let me know. I tried to start many apps but the free RAM still around 150-180 MB.

[LG Optimus 3D] Stunningkun:
Well if u r testing the conditions under which GC occur. Last time it happened was 4 days ago, in the morning the usual quest of finding the mobile and called through my land line number. The call was going though but phone wasn't ringing. I eventually found it. I called again but the same result the interesting part was that as i was holding the phone when I was calling I can hear the noise which happens on landline phones when a cell phone is near by on call but my phone was silent. My verdict the baseband was working but the rest of OS was not able to detect and ring the phone (I guess thats what GC is :)). After a few retry I restarted the phone and the phone started working normally. I was on v20b the first it happened on it since release. I switched to v20g yet to falter.
[LG Optimus 3D] IFLPI:
Here in Poland one person wrote on the forum that he returned the phone to the operator with this ghost call issue, and they gave him the possibility to exchange it to the new LG Prada. He accepted it, and wrote that prada is blazing fast. Much faster than sgs2 or phones on custom roms.

OPTIMUS 3D with Gingerbread ROM (V21A and 21B) RANDOMLY MISSES CALLS! It means that when somebody calls us, THE PHONE DOESN'T RING and there is NO RECORD OF A MISSED CALL!!!

LG, please FIX THIS! The Gingerbread update was issued on Nov 15 2011 and you have not provided a solution YET. A lot of your customers are frustrated. There is even a thread for GHOST CALLS on XDA Developers.

Don't forget, no matter how sophisticated, this is still a phone. Missing important calls is a serious reason to NOT buy this device.

UNTIL THIS ISSUE IS RESOLVED, I CANNOT RECOMMEND THIS DEVICE TO ANYONE.
[LG Optimus 3D] ThiaiZ:
how ? Isn't LG prada a single core phone with 512mb RAM + GB ? How can it be faster than dual core phones ? Specially the SGS2 ?
[LG Optimus 3D] IFLPI:
Lg prada 3.0 is omap 4430 1 GHz dual core, with 1 Gb of ram. The guy wrote that soft is very optimized, and very responsive. Dunno, for me that phone also was not interesting, but even you ported the prada ROM and it was very responsive. So maybe crappy lg is starting to compete with Samsung starting from now. Unfortunately we have less luck with this lg 'ghost call phone'
[LG Optimus 3D] ThiaiZ:
You are right sorry. Maybe had in mind something I saw before the Prada release, but anyways I still have doubts that it is better than sgs2.
[LG Optimus 3D] IFLPI:
Yes, it sounds doubtful, but the guy had sgs2 (his girlfriend) for a long time, and he bought her Prada. He owns galaxy nexus, and is saying that prada is quicker than them both. Other ppl also was very suprised that anybody writes so good about the lg phone. Maybe i will also try to return the phone to have it replaced. But it dependends on the operator good will I think.

But they 100 percent must know about the issue, thanks to xda, it became famous (ghost calling method :) )
[LG Optimus 3D] cool_recep:
Lg Mobile Update Tools was updated to 1.5.6.0.

Hope that this is a sign of ROM update coming from LG.
[LG Optimus 3D] cheong12001:
Actually, i have watched a lot of forum from china ( in fact i am a hongkong user), all of them said they haven't encounter any ghost call anymore when using v20g which is release from china Beijing, the KDZ is available from here

http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP920/ABUOML/V20g_00/V20G_00.kdz

This is very encouraging, and they said v20g have completely solve the problem of ghost call. Therefore i highly recommend all of you to install this v20g as fast as possible for testing! !! if anyone still have ghost call, plx say dont feel lazy to post on here!!! your experience always have good value for us to find out a ghost call free version:D
[LG Optimus 3D] cool_recep:
You sound like a douchebag LG employee. Why should I flash a chineese ROM to my phone when I am thousands of kms away from china? Do you guarantee that my operators signal will be compatible with that ROM?
[LG Optimus 3D] Meemo23:
How about you learn facts before you open your mouth.. You only need the baseband, The baseband is all that matters you don't need the actual rom it self you can root it and replace it with a custom 21D rom and still have V20G baseband.. People tend to forget that GC is a baseband problem and not the actual rom it self's problem.. To be honest i believe that guy because i have had V20G and i have honestly had no missed calls and i am loving my phone very much now..

Then again i could be lucky but i flashed V20G baseband and am using a V20G rom i made removing all Chinese crap out of it.. And adding all the 21D apps and framework. It also fixes battery stats so overall i am very happy now.. That is untill i get a gc then i will be pissed...
[LG Optimus 3D] cool_recep:
I know that baseband causes GC and I have Optimus 4G AT&T ROM on my phone to solve the issue.

But either way, I have to mess with all this stuff to flash that baseband. It has been 3 moths and LG is just watching us.
[LG Optimus 3D] oile:
just few questions then :)

How have you verified it is an all new baseband (despite the version displayed) ?

Any guide about how to flash the 20G baseband?

Doesn't LG Flash tool work anymore? R&D test tool ??

Thanks

my friend "tf1222" gave V20g a 4-days-test! quoted from him 'no ghost call' !!

all the poor signal circumstance which V21a would absolutely get ghost call, and Froyo would absolutely get auto-reply (or voice mail), but V20g get normal ring phone call. althought the signal sign goes nuts! u can't trust the signal icon.

BUT...

there is a problem, the V20g seems not that stabile, it got frozen several times. and while it hanged, you got gc ╮(╯_╰)╭ !!!!

he might keep testing v20g, 'cause V20G IS the best we can get so far!

again! thanks to u tf1222!!

due to my mood, i will stay in froyo for a while!
[LG Optimus 3D] oile:
Thanks :)

I've had obviously seen your thread before,

but that "flash it with smartflash" remained unclear to me..

..as the only tools I've ever used on O3D were LG Flash tool and R&D test tool .

Could help us further?

EDIT: I'd put V20G BASEBAND ONLY on my Acura v21D .. I surely don't wanna do a complete flash of the chinese 20G

Probably because their FB page is only some community/advertising spaceand has no real support purpose. They don't care about technical problems there.

You should Spam their technical support, if that's possible.

If they don't fix that crap in the next few weeks, I'm going to buy a Nokia Lumia 800. That really grabbed my attention :p
[LG Optimus 3D] dreccon:
I was there just now. Our posts are still there. You just have to click the link that allows you to view posts from everyone and not just LG.

Found this post under Vengeance thread. If it is really true, than we are all fu**** **. The cause for ghost calls would be hardware related than.
[LG Optimus 3D] zwoggel:
I was using both basebands and I never had problems with the FroYo version (10k that was)

Right now I'm using the GB baseband from V21A but disabled 3G and that also works perfectly.

I'm pretty sure it's the baseband. It's not only ghost calls but complete loss of network connectivity. Only rebooting the phone helped for me.

With FroYo BB or GB set to 2G only -> no problems here.
[LG Optimus 3D] Willievi:
Ive been using the P925 ROM with Froyo baseband for a while now and that seems to have solved 90% of the issue if I set it to 2G only. Data drops every week or so and needs a reboot, so I reboot it over the weekend when i remember and have no issues further. 3G still has constant data drops and missed calls and non phonelike behaviour
[LG Optimus 3D] dreccon:
Right... so we cripple our phones to avoid ghost calls and disconnections. I must mention here that I've been using AnTuTu CPU Master Free and set the minimum frequency to 600 MHz and I haven't had any complaints since then. Then again I don't know. There's always a chance that somebody did call me and never mentioned it.
[LG Optimus 3D] sak500:
Didn't work for me. I set it to 600 min as well and after a day i noticed after a recent full charge my phone battery suddenly lost 30/40 points in just a short time that's when i tried to check my credit and the phone gave a msg of "internal reorganization" or some crap.

Two things come out of this.

1. upping the min clock doesn't work.

2. When you see sudden drop in battery then it's your signal not working properly and phone is busy trying to sort it out. I have cpu+temp widget and it kept showing 1.22ghz and not going down to 600mhz.

Anyone w/o rooting or installing ROM manager (meaning stock original GB) facing ghost calls?
[LG Optimus 3D] Barracuda77777:
I flashed 20B Australia Optus branded which can not be rooted anyways couple weeks ago and I still had ghost calls and having to restart the phone,

however, I have this morning flashed with 20A Australia which is none branded, looks very promising, I did a full wipe, system and internal SD, so far Battery is lasting well and no need to restart the phone, looks like it is fixed as before it never last more than couple hours, or hours 3 max. it is now 9 hours!

Edit: more than 24 hours no missed calls or sms and no restarts needed due to baseband crash
[LG Optimus 3D] dreccon:
This leaves us with two options:

1. If we mainly use WiFi for internet, then we stick to Gibgerbread and disable 3G.

2. If we mainluy use 3G, we downgrade to Froyo and remember not to set WiFi to stay on while screen-off (or we'll have the random reboots issue)

I still insist that until we have a patch we must keep posting to LG Mobile's wall every day because that is proof of how many we are.
[LG Optimus 3D] vpamir:
I flashed the 20g kdz yesterday. It's not completely chinese, it has english and 2 different versions of chinese, mandarin and cantonese maybe i don't know. I didn't want to restore my 20d backup over it because they might have done something to the android system itself to fix the ghost call issue besides the baseband and if i flashed back my backup then i would have broken that. Anyways it doesn't have google apps, no market, no maps nothing. It has some chinese replacements. I got rid of them all with rom toolbox. But first i rooted the phone with megatron which went flawless. I installed rom manager 5.0.0.1 and clockworkmod recovery 5.0.2.7 through it. Then i flashed gapps-gb-20110828-signed.zip. That gave me all the google apps including google play. After that i restored all my user apps+data from 20d using rom toolbox. The phone seems to be stable and responsive. I haven't encountered any ghost calls yet, i'm still testing. If i get a ghost call i'm gonna write here.

Another thing. It's not related to the ghost call issue but as a lot of people are following this thread i want to ask you guys something. I use sixaxis controller to connect my dualshock 3 to my o3d over bluetooth and it only works on CyanogenMod. But in CM HDMI output isn't working and i can't connect the O3D to my tv to play playstation one games using DS3. I know that it's because cyanogen mod uses a different bluetooth stack or whatever. What i need to know is if it's possible to replace the bluetooth stack of the official rom with the one which is inside cyanogen mod. Is it possible? Are there any threads which discusses this? If you could point me to the right direction, thanks...

Following up my previous post:

I did test running a game "Dungeon Defenders" with all apps started after reboot.

I can not check my free RAM was below < 100 MB, because I was playing game.

I did call test about 100 calls in 2G and another 100 calls in 3G. I set to 2G only or 3G only.

And the call always through. I never get a single ghost call at all.

I did also some tests with Bluetooth On, WIFI On, GPS On and make another 50 calls in 2G and 3G, and I am still not getting a ghost call.

I dont know what to do next.

I have inform you what I did at my very first time having this phone.

My O3D running stock rom GB 2.3.5

Baseband L6260_MODEM_SIC_01.1042.00

Kernel 2.6.35.7+

Build Number GRJ90

Firmware V21a Nov-15-2011

I did upgrade to GB using LG mobile support tools.

Rooted using Super One Click 2.3.3 or Megatron, I forget because at the same time I root also my O2X.

Installed CWM from ROM Manager

I used system tuner to disabled start-up for many apps. I keep only the important apps.

I manage to have free RAM > 220 MB.

I never install any killer apps.

Here is the list of running services on my O3D:

Settings

Sense 4 Clock White

com.lge.omadmclient

DRM service

Music

LG Keyboard

Cached Process:

Android Core Apps

Google Search

Home screen tips

Whats New

Messaging

Home

Alarm Clock

Superuser

Youtube

Gallery

My uploads

Google play store

Social+

As of now, I never experience any ghost call and am running V21A the one that most of you reported to be the worse ROM with ghost call.

If may be any of you can follow the same like I did and do the test ?
