mongoose, that 2MP mod is quite cool, it gives us the 2MP images (with this mod alone) that we needed massively tweaked drivers to get the same on the K750!
This tends to prove to me the K800 sensor is quite good.
Perhaps the phone is not really powerful enough to run full quality 3MP images (due to phone resources, no fault of the sensor or camera module itself.)
Or, perhaps camdriver just needs to be tweaked forperformance more than SE could be bothered with!  I'm going for that option.... 
I think you're right that the phone is not powerful enough. I don't think it has the capacity to cope with images much larger than 900kb. It is interesting that you can improve the 2mp images by increasing the MAX size and buffer to 900. But, you can't take the 2mp much above 900kb either without making the camera unstable. So, the phone is probably limited to creating a 3mp image is limited to around 900kb.
I think the jaggies are coming straight from the sensor and that the phone isn't filtering it out enough. And, I actually think the 3mp pictures are too Sharp. Perhaps if we find a way to reduce the sharpness the phone might apply some anti-aliasing. |

Hm.. I think phone actually already implement some \"blur\" for oversharp picture, but this can only happened if we set sharpening value to FF a.k.a reset sharpening level, so phone will judge it will increase or decrease sharpness picture that taken by sensor. |

What I do now is just set image size bigger (less compression, thanks mongoose), and make sharpening value to 0 a.k.a do nothing for sharpening, so what cam sensor get will untouched (we can retouch later with any digital lab software such photoshop or any other else), and set any images captured with Xenon flash to ISO 320 (originally ISO 400 but it's overbright, and try set to ISO 250 but some cases tend to darker).
Meanwhile I think this most better result I can get on camera phone, not overbright, oversharp or any other, it's more natural, like what I get on normal digital camera  |

nice work. Now I'm off to compile all that in a driver... 
2MP changes, plus sharpening 0, 100% compression, flash to 350.

Max, forget about 100% since I already try it reset (not saving) so I back to 95% only. |

plz upload mongoose3800's driver. I have a k810i, and i like the k800i camdriver better. Does mongoose's camdriver support VR @ 30FPS?
And if possible, upload some sample pictures (make this topic like supermod for K750/w800/w810 thread)

tested kopritis 2.8 vs 2.5 stock driver. 2.8 was much sharper. Now need to correct the white ballance... and enhance the VR from 10FPS to 30FPS. After that, we can concentrate on colors. |

What max file size do you have for 2mp? What buffer size have you set for 2mp. If you go above 900kb it will crash. I've been running 900kb with 2mp for 2 days now without a single reset and I have taken lots of shots. I've been playing around with compression ranging from 90% to 100% and have not had one single problem. |

OK - so I've got the 2.8 camera driver, and got XS++ up and running and connected to my K810i.
In XS++ what configuration do I use?
'Flash' or 'FSX'?
If 'Flash' then do I 'Flash Main Firmware' or 'Flash File System'?
Thanks in advance |

You must be using a different version of XS++ to me.
My K810i phone is not listed on there and the BreakXS box is in a different place.
Every time I try it I get a failed message.
Can anyone help? |

Vinny ur probably not following the instructions accurately. just try doing it step by step and ull get it, Max's guide is really helpful, there's also another guide, with pictures for XS++ on the forum somewhere. http://www.esato.com/board/viewtopic.php?topic=153990 |

Would it be down to the fact that the K810i is not listed in XS++?
I have tried it step by step more than ten times now and it's just not working!
Never mind - I had XS++ v1.5. Downloaded v1.6.8 and it worked first time
