Custom ROMs External Screen Caller ID Issue. Solution?

[freibooter]

I recently upgraded to Erofich's excellent Windows Mobile 6.1 Standard ROM v9b and it is working absolutely brilliantly with only a single, but sadly agonizingly painful, flaw:

The external screen won't reliably show the caller's name and picture from the phone book. Instead it shows the caller's number and the "caller unkown" picture.
It never works on the first attempt after the phone has been turned on but when the person calls back a second time name and picture are usually displayed perfectly fine for this caller - until the next reboot.

Erofich claims that this sadly is a typical issue with most if not all custom StrTrk ROMs and I have no reason to doubt him. And since I otherwise love this ROM and already put a lot of effort into customizing it and setting it up perfectly I have absolutely no desire to test other ROMs for this behavior.

But since the caller ID works fine on the second time a caller calls, I'm wondering if this might be an easily fixed bug. Maybe there simply isn't something initialized on boot that normally should be?

So my questions:
* Who else experiences this bug?
* Are all custom WM 6.1 Std ROMs affected or are there exceptions?
* Has anyone already found a solution to this?
* If so, can it be applied to my current ROM?

I can't be the only one annoyed by this infuriating bug. I like to know who is calling me without having to open the phone first (the caller ID on the internal screen works perfectly fine all the time) or withjout having to memorize every single phone-number in my address book. :)

Hi

I'm using the Clean STD ROM WM 6.1 OS ver 5.1.19202

I have experienced this problem ONCE only, a few weeks ago but not since. I've been running the rom for nearly a year now and that was the only time.

What happened in my case was that it displayed the name but not the picture, which did appear eventually after several seconds just as I answered it. It seemed like there was a delay finding the picture or something.

What would be nice though is if there was a way to change the unknown caller picture (blue outline with ?) so something of our own choosing.

I don't care about the unknown caller picture, it fits nicely with the rest of the StrTrk external screen theme.
And I wouldn't mind too much if it occasionally took a little longer to show the correct picture.

But for me, the first phone call from a caller after turning on the phone (even when it has been running for hours) always won't show name and picture. If only one of both were missing, I could live with it - but this is actually causing some serious problems since I now frequently have to identify callers by their number and ringtone. :(

I think this is a bug in Erofich's ROM that somehow can be fixed, but if Erofich himself, probably the most experienced ROM-cooker in this forum, can't fix it, who can?

all of the custom roms (roms by me, GnatGoSplat, Pampooh, etc) are based on cingular 4.1.502.5 rom
try to take SubDisplayDll.dll from last Qtek 8500 rom, and rebuild your rom using kitchen

Thanks for the reply, Erofich.
My educated guess is that the SubDisplayDll.dll is not the source of the problem, it seems more likely that something that is supposed to call this dll isn't correctly started.
Well, since you STD_v9b ROM seems to have a time-bomb I'm forced to find a different ROM anyways :(
Well, this is my chance to find out how the others are behaving - lemons ... lemonade ... etc.

This is the Rom I've been using :

you could give that a try.

I don't think I had such problem with 1.1.7, less lag/delay before the name is displayed (will only get the number) in the call history as well.
