1) This user suggested in another thread ( http://xdaforums.com/showpost.php?p=32235455&postcount=2905 ) that we can leave the Froyo baseband, flash whatever Gingerbread ROM via CWM and then use GetRIL to restore the layer that communicates with the baseband. That way we could use the Froyo baseband together with any custom Kernel and still have no ghost calls.

2) My understanding is that the ghost calls issue is caused by a baseband hang. The patch in v21e is in the kernel and it is simply a workaround, not a true fix. The kernel detects the hang in the baseband, kills and restarts it before the hang becomes noticeable to the user, whereas in previous kernels the hang would remain undetected for hours causing the full-blown ghost calls issue. If this is true, then using the above method should work and we should be able to use the latest CyanogenMod with the old baseband and without ghost calls.

All that remains is someone brave enough to try it...

Anyone know if the firmware works on v21e p920h of Brazil?

operator TIM?

how can i know that i have ghost calls? maybe sound stupid but i dont know
[LG Optimus 3D] pthacker85:
ghost calls solved with v21e
[LG Optimus 3D] dreccon:
XBSA's ICS port is not compatible with v21e so, if you want ICS, you have to flash an older baseband (whichever works best for your country/operator) and this means the ghost calls issue may come back. That is why I tried the ICS port for one day only to satisfy my curiosity and then reverted back to Gingerbread.

What I did before the v21e update was to forward calls if unanswered for 20sec to my wife's phone. This way, if she got a forwarded call and I didn't have a record of it, it was a ghost call. :cool:

i have rogers o3d (p925g) tried to root without success, so cyanoging is out of question , and didnt found a simple way to flash back to froyo!

is there any news about a possible fix ?

i have v20c on my o3d and no available updates with the lg update program

I re-installed everything fresh and the phone had been working perfectly.

there is no root yet but at least the phone is working like a phone again.

Please give feedback! as I am still skeptical about the problem being fixed!

Good Luck everyone, I was one of the first people to report on this issue on LG website where you can find here,

I have tried many roms, but this is the first time that I did a full factory reset after flashing with a formatted internal SD.

Excellent work my friend! That page with all the ROMs was awesome! I'll try the v20a and report as soon as I can.

>ThiaiZ

If v20a can, at some point, be rooted, do think you could cook a ROM that installs easily through CWM based on it?
[LG Optimus 3D] ThiaiZ:
Yes, I can do that.

I followed your instructions and flashed the v20a for Greece/Cosmote. It took like 30min for the update window to un-freeze on my old XP laptop (so be careful everyone - as Barracuda said: LET IT RUN).

After factory reset and initial setup, things seem to be running OK. All I have to do now is wait and see if I miss any calls. I'll report...
[LG Optimus 3D] dreccon:
Today, while trying to make a call (with v20a ROM), I got the message "Reorganizing internal process. Please try again later". It took about half a minite before I could make a call. I had seen this message several times with v21a, so this is not a good indication. I'm afraid that if this "reorganization" happens while receiving a call I'll still have a ghost call.

I also have the ghost calls issue in GB and I downgraded to Froyo but never actually tested if it works. I switched back to my iPhone because I dont wanna miss any important call.

Man, that explains a lot. I fully charged my phone all night. The following day I went to work but I forgot my phone at home. When I came back after 8 hours, battery was dead. I had 5-6 missed calls and 2-3 sms. I couldn't figure out how the battery died. With normal use, battery drops to 15-10% after 24 hours.

Never thought that baseband problem have caused this

GHOST CALLS ON v20a

I'm sorry to bring the bad news but v20a still has ghost calls. I confirmed two of them today. Let me stress that this firmware cannot be rooted yet!
[LG Optimus 3D] Barracuda77777:
Very Strange, 20A have solved Ghost calls for me, it looks like it depends on the network, in any case it shows the lack of compatibility of an unlocked O3D running on GB. So if you want to travel around leave it at home.

in the meantime, LG is still investigating the issue and will issue a fix sometime in the next century......
[LG Optimus 3D] dreccon:
I am really tired of all this. I'm going back to Froyo (v10b - it is what I bought the handset with) as soon as I find some time. I hope ICS gets released as promised and I'll re-upgrade then.

[LG Optimus 3D] raskall:
My experience is that it is NOT cpu speed-related. I have used setcpu and sett minimum cpu speed to 600 MHz. Still it stops working when I have high speed enabled.

I saw someone saying that it was the HSPA network that caused it and that people in areas that do not support HSPA doesn't have this problem.

This is consistent with my experience: With the phone set to "2G only" (just edge network) I never have ghost calles or missed texts. As soon as I enable the H the phone starts acting up and stealing my calls.
[LG Optimus 3D] Kresstian:
Hi. Does anyone know an app that can monitor connectivity, and make a log entry whenever connectivity is lost? After what i can understand, the ghost calls happen when the baseband crashes and connection is lost.
[LG Optimus 3D] vanvn297:
after a long time of trying different rom, i decided to turn off 3G :D. slow internet connection is still better than ghost calls thought.

people have you heard anything from LG about our issue?

I didn't hear of such thing. Maybe those people didn't flash the 21e baseband with the ROM.

The best way to flash a completely new ROM is the KDZ method. Here is the guide: http://xdaforums.com/showthread.php?p=18082599

As I already said, flash the 21E firmware. It fixes that problem.

guys, i tested a little today... there is no way of knowing or to force baseband crash...when it hapens it happens.

so i called myself for 100 times today, and it finally crashed.

funny thing is that sometimes it recovers by itself. i am calling, and there is message saying that my phone is off. Then minute later i call again, phone rings. So obviously baseband managed to restore itself.

Then by investigating a little more i figured aut that restart connections app from market does nothing, and then tryed airplane mode. And it worked. no calls. airplane mode on, airplane mode off. ringing again.

So what i did, installed tasker, and set it up to enter airplane mode for 3 seconds every half hour. So i guess it wil work this way ok for me.

I went back to gb bcos i really hate froyo, and there are no good roms.

Only thing i dont know how to set up, is that tasker executes airplane mode even if i am in a middle of a call.

So if anyone using tasker, how can i set it up to ignore all rules if phonecall is in progress?

Thank you

solved in tasker...not to enter airplane mode while in call.
[LG Optimus 3D] udobhv:
Hello,

I solved my problems... :D

1. Battery drain

I just installed "Juice Defender" and it helped...

2. Ghost calls and Black Screens

I rooted my phone and installed an CPU-app. After that I set my minimum core clock to 1000mhz and chose the autostart option...

Looks like the phone has problems to wake up from standby...

Thats it ... no more problems...
[LG Optimus 3D] dreccon:
I finally decided to downgrade to Froyo. I found my operator's v10k firmware and used the above method. When flashing was finished i switched on the phone and got into a BOOT LOOP! If that happens to you, do not worry, it's easy to fix:

1. Go to RECOVERY MODE. To do that first switch off the phone by long-pressing power or by removing the battery and putting it back on. Then keep 3D button and Vol-down pressed and press power until screen on. Release power but keep the other two buttons pressed until you see the recovery screen.

2. Select FACTORY RESET. Wait until it's done.

3. Select RESTART.

The phone will now boot normally.

I'm still so sad to see there has been no movement on a solution to the ghost calls problem... I have switched back to my iphone 4, while I look at my O3D sitting on my desk daily. :mad:

Can't use a "phone" that won't receive calls :confused:
[LG Optimus 3D] Barracuda77777:
It's am using my Iphone 4 as main too but at least I have a second sim card that I am using in the O3D, had ghost calls today, very disappointing, the sad part is LG are denying that the problem exist. I am still the only one in Australia with problem according to LG.

As soon as the SG3 is out I will be switching. LG so much potential with this phone but crappy software. I think the hardware section of LG is miles ahead of their software development.

Froyo is not that bad...

I'm running Froyo now. It's not that bad! There are only few things I'm missing:

1. The thumb handle for the text cursor.

That's not really a problem because I have installed Go Keyboard and enabled the arrow buttons to move my cursor.

2. The 3D button does not act as a shutter button in Camera.

There's no way around this, but it's not a big deal.

3. I cannot use videocalling in Skype.

This is important but I can sacrifice it in order to have no ghost calls. There are also modified versions of Skype from droidrx and theos0o (hope I got the names right) that allegedly support our phone (haven't tried them yet).

EDIT: THE LATEST OFFICIAL VERSION OF SKYPE SUPPORTS VIDEOCALLING AND THE FRONT CAMERA ON FROYO.

4. It is not possible to overclock.

That is not too important. Our phone is fast enough the way it is!

That's about it. Everything else works fine. The phone is very responsive and the visual difference is minimal.

Is there some other important difference that I'm overlooking?

OK, LG is crappy and can't figure out the bugs in its firmware, but do we really need to have a dysfunctional phone just to have the latest version of Android?

I do hope that we do get our ICS update in September and that it is has no more bugs! Until then I'm sticking to Froyo.

Ok, now I got "ghost calls" on Edge network also. BUT I will try to try another conclusion:

Is the problem related to switching between technologies on weak signals?

Because running on Edge only eliminates the problem while I work in my home town. That means not commuting by train.

Today the problem arised during a 75 minute train ride where I lose connection several times. Do the baseband crash when signal is weak and trying to revert to an "older" type of network?
[LG Optimus 3D] dreccon:
>rascall

I don't think this is the case. We seem to get ghost calls even if our phones are set to use 2G only (see above posts). Actually this was the catalytic event which led me to downgrade to Froyo: I had a ghost call after I had set the phone to 2G.

I think I have tried everything. I have flashed v21a with factory reset, v20a again with factory reset, tried these with 2G and 3G mode. Tried both with upped min-clock frequency. There's no way out, the ghost calls are always there. The only real way to get this phone functional again is to downgrade!
[LG Optimus 3D] Stinger2U:
Hi guys. I bought my Optimus 3D 2 months ago and never had any problems until I upgraded to gingerbread. I waited for the official LG update via the LG Software Update program and updated my phone one week ago. Since then I've had a few ghost calls. I can't believe LG missed this in their software tests. Tried the 2G trick but it didn't work, but at least it seems there are less ghost calls when only 2G is on.

EDIT: I have e-mailed pocketnow, phonearena and engadget about this issue. I'm hoping if they write an article about it, then maybe LG will respond quicker and fix the issue.

For those who are planning to downgrade, I tried the latest official version of Skype and it works perfectly on Froyo. Videocalling is enabled and the front camera is also enabled by default.

Really? Or sarcasm?
[LG Optimus 3D] fclage:
fixed?

Strange... i've fixed the problem... no more ghost calls, lost sms or rip messages.

A few days ago I got fed up with that when my phone went offline for an entire morning, and I lost important calls.

I formated the phone (power+vol down) and made full factory reset + cache reset (a few times i confess but I don't think overdoing it does any difference tho).

I keep everything on all the time (gps+wireless+bt+3g+full bright) and use juice defender gold (bought 1 month ago) to optimize battery... I've also noticed that the battery usage is a bit lower (with everything on, + calls + sms + email (exchange) + fb (1h interval) + remote management (tv/logmein/rdp) + skype + bit of gaming) last me for the 24h i need until the next charge.

The only thing I miss right now is the root for the v21b firmware i currently have.

I'll post an update if I start to see any rip message or ghost calls.

Hope this helps

Wikipedia entry

I just edited the wikipedia page for Optimus 3D

==Software==

The Phone Runs on Android 2.2 (Froyo) from stock. It can be updated to Android 2.3.5 (Gingerbread) although some phones may require a computer to do this.

Since the release of the "Gingerbread" update (mid November for the European open handsets), many (if not all) of the handsets suffer from what the users themselves refer to as random "ghost-calls". While a caller trying to reach an Optimus 3D owner hears a normal ringing tone on his side, the Optimus 3D doesn't really ring and there is no record of a missed call either. This way, the called party has no knowledge that somebody tried to reach them until the caller complains in person. There is a dedicated thread for the "ghost calls issue" at the web site of XDA developers ( http://xdaforums.com/showthread.php?t=1475351 ) and several complaints have been sent to LG's support page and Facebook wall by users from different countries. Sadly, LG have made no public announcements regarding the issue...

LG have announced that Android 4.0 (ICS) will be released for the Optimus 3D in the Third Quarter of 2012. Users hope the upate will fix previous issues, although they demand that a patch is released as soon as possible.

Here is the message I sent to engadget:

==========================

Dear Engadget editors,

We, all LG Optimus 3D users, are suffering from the buggy Ginger Bread update that LG has provided after months of waiting.

The update made the phone unreliable since it introduced a problem called "Ghost-calls". This problem can but you in trouble since somebody may call you and you are not notified. He just will come to you next day and says why you don't answer may calls and reply to my SMSs? Your answer would be that you didn't receive anything!

This problem caused many problems for consumers and many on them are mentioned in this thread at XDA-Developers forums:

http://xdaforums.com/showthread.php?t=1475351

Many of consumers believe that the problem is related to Ginger Bread base band.

To conclude, LG's engineers are not aware of this problem and we have been waiting for an update to come but nothing happened. We are asking for you to write an article which may moves stagnant water.

==========================

I encourage all of you to do the same.

Barracuda77777, it may be a good idea if you share the video that you've recorded so that we can use it also as a proof.

When the phone changes the conection, the wifi drops, the indicators turn white and no incoming calls.

I am a telecommunications engineer and are very interesting in the problem.

I'm still making tests, but i don't have any tool for log the activity of signal changes. I'm searching.
