not so good news...
I looked around because I got ghost calls on stock kernel, too and (only) found this:
It's about the LG Optimus and has also a talk about that here at xda:
When you take a look at the answer LG gaves (1st link, 1st post) then the patch is BASEBAND (radio/modem) related which means we maybe can not solve that by the kernel (only).
@samno seems to have a "ghost call" patch made for his ROM before that above patched firmware. Unfortunately he has not described what he exactly patched in the Kernel(!!!!!) to fix the issue.. I wrote him a while ago but no answer yet.. His git commits do not show that patch either (or I'm not able to find it).
You can find his Kernel thread here: http://forum.xda-developers.com/show...36&postcount=2
so at the end it MAY be possible to fix that by the kernel but no one knows HOW (besides @samno of course) and it MAY be possible to fix by using another baseband then UCLJ3 or RUXKJ which both were tested and having those ghost call issues.
The other open question for me is: Is this issue in other ROMs like @bubor CM11 too??
I will test also the other basebands we have for this device maybe one of the others have not that problem... The other choice we have is hoping that @samno is answering and let us know how to hopefully fix that.. Is it voltage related? CPU freq? what has he done for his ghost call patch....?!
In the meantime I try to catch logs (logcat & dmesg) when the ghost call happens..
But back to serious: The problem is that there is no real patch available by LG or him. What he had done was to do a file diff between v21a and v20p firmware's and merge the changes. so as there are many changes no one knows what has fixed that besides LG of course.
So we are at step 1 back again. I will ask in the other forums if they have encountered that issue, too.. we need to narrow that down where this comes from.
btw: I currently trying and trying to reproduce a ghost call but it does not happen anymore.. this is strange.
Would be really helpful if the users here using sediROM could report the following.
This is really simple - can be done quickly - but may help a lot!
- which kernel and modem do you use - A hint like "installed sediROM Version X.X with default values" is enough but when changed anything let me know what
- I have received ghost calls (missed calls)!
I have never missed a call (I'm pretty sure)!
I have no idea if I had received a ghost call or not...
Any answer highly appreciated!
