Obviously ICS alone will be awesome to have on this phone. However, this device isn't getting any younger so getting the latest android will really rejuvenate it. More devs will probably be interested in the marquee if it's on the latest and greatest software. Also, (and I'm no dev), but I've read that ICS to jellybean is a much easier task than gingerbread to ICS. If so, it makes sense not to waste a lot of time on ICS when you can use that time on JB instead.
Regardless, I'm just happy that you devs are putting so much work into this phone. It's seriously a completely different device coming from stock!
Great job all around!

I was about to get a eco v, than tdm and blood got ics working now I wanna keep this phone. Stock ics is better than any other manufacturer skin.

Currently playing around with the image formats for the camera.
It looks like the front and back cameras actually have different image formats. Switching the preview conversion function for the back camera from y422_to_yuv420() to yuyv422_to_yuv420() made it look better. Still not correct, but better.
The IMX072 driver source claims that the sensor supports exactly one format, V4L2_PIX_FMT_SRGGB10, which is known as Bayer10 RGGB. I don't have an IMX072 datasheet (is it available?)
I'm trying to wrap my head around these formats and write code to convert SRGGB10 to YUV420 for the back camera.
Handy references for color conversions:
SRGGB10: V4L2_PIX_FMT_SRGGB10 ('RG10'), V4L2_PIX_FMT_SGRBG10 ('BA10'), V4L2_PIX_FMT_SGBRG10 ('GB10'), V4L2_PIX_FMT_SBGGR10 ('BG10'),
YUV420: V4L2_PIX_FMT_YVU420 ('YV12'), V4L2_PIX_FMT_YUV420 ('YU12')
Conversions: YUV to RGB Conversion

Oh, and a couple more things:
After fixing up the latona camera code to only use supported methods, the save picture code is running out of memory during JPEG encoding. There must be either a way to have hardware encode it or an OEM camera library function that is optimized for this.
There doesn't seem to be any support for auto focus, but the OEM libraries have some function names that looks interesting.

Well it looks good on paper lol but one must take into account the further we move away from Android 2.3 the higher the number of incompatible apps in the market. As it stands Android 4.0 only accounts for about 15% of Android devices, that's nearly 10% less then 2.2. I believe Google realized this and that's why it only went up 4.x opposed to hopping to 5.0 and it may just be my imagination but it seems like the only apps updated are corporate, home brewed (from our community) or editors choice and besides I hear porting from ics to jb is a breeze so plz 1 step @ a time lol.

Found this but don't know how much help it is.

Thanks I'll take a look but the latona camera code does have a neon lib already.. Check the code drop.

This is the color conversion function I was looking for all day...

I hadn't seen gabwerkz code repo, thanks for pointing that out. "Social coding" is difficult for me to do, my first instinct is to hack it up myself.
Judging by his commits, he may have the camera and camcorder fully working. Or at least mostly. So I'm thinking we should have camera, camcorder, and vibrator this week. Yay!

Hmm, after flashing the LS855 zip plus the vm855 fix, I see "Sprint" on the lock screen and the notification drop down. I guess that must be controlled by eri.xml. which is in framework.jar.
So we have:
framework.jar at 3.9mb for one line of different text.
Mms.apk at 2.9mb for about 10 lines of different text.
build.prop at 5kb for a few lines of different text.
So we're looking at 6.8mb of unique data per phone, times 3 phones (for now). That is two more than a basic ROM would have, because a basic ROM has one set of unique data, of course.
So for a unified ROM, we can expect the size to increase by about 13.6mb or about 13%. That's a whole lot more than I was expecting.
And it will be somewhat worse on the thunderc family because they all have slightly different proprietary files for the RIL.
But wait, I remember that edify has built in support for bsdiff formatted binary patches, which I think is very similar to rdiff. So I'll need to look into that, especially for the sniper family.

Tdm, just thought I would mention mms works sending and receiving on my AS855 Ignite with the sprint Mms.apk from the LS855 build

Doesn't CTMod have a screenshot option built in? Then you could use Tapatalk to upload it after configuring androidforums account to it... then voila you can insert images into your post easily!
