hehe, wrong... my led is still alive and he is greeting you

not exactly MIN but LAST quality which should be checked if anything higher than LAST failed. however MIN quality is igonored because of additional compression rule: jpeg MIN, AVERAGE, MAX file size...

the funniest thing: camera can crash because of too high MIN file size rule
for example in situatuon when we set MIN file size to more than 100kb and then we take very bright snapshot. result will be very small 50-70kb file with 95% quality (even if MAX quality in driver is much lower). bright areas and gently blurred areas = very good compression (small file, big quality). that's why sometimes camera can crash when ENM was used - driver has too high MIN file size limit (often is 400kb). i found this long time ago, that's why 6.5 has MIN file size = 0


very good point!
it's rather some influence on battery when snapshot is unsuccessful then it must be repeated, sometimes even many times. in practice it's almost impossible to take max 600kb photo with more than 90% quality. if we set MAX quality to more than 90% then some first snapshots may be unsuccessful - loss for the battery? surely yes

Tuner

currently i'm working on it will be available soon with tool v0.3

BOSSHOGG

in normal driver macro mode is: full range (macro range + normal range) - stupid idea but not mine
macro range is ~10 - ~40 cm


video quality can not be set, only max possible fps (i already have max, 15fps)

@Raiderski: I thought you would say 'no'. Actually i found the retry-times when I took pictures at night with flash and the led kept flashing for 5 times then it saved the pictures.

@About the lifetime of the camera: Raiderski is right at a certain point. But there is no need to worry about 90% more (90-95) since I tested at 100% and it works fine, apart from places with very high details -> not good. I will carry out more tests for 95% compression on CID36/49 so that the phone will work better. This problem used to be on board a long time ago when the first modders encountered it. I will test with various values of these 3 properties:

cam_ss_sync=*;
cam_ss_sync_9=*;
cam_ss_retries=*;
Is there any comments about Colour of CT1 and CT2

@_@ I love my lunch time

Yape, that why I think 89% on a4a is the most stable and 91% of raiderski is Perfect 95% for cid49/36 will take me time (but it is alright on w810i).

For w810i at 95%. I have found the LED is flashing more than 3 time, shall i switch back to 89%.

not exactly. snapshot retakes are because of not fitting rules of jpeg compression: quality and file size. if you want higher quality then file size will be higher too. right? if max quality is increased then file size should be increased too in suitable proportions. unfortunately every modder forget to set proper file size rules for max 95% quality

610kb file size limit and 95% quality? well... impossible!
that's why you have retakes - 95% quality = big file size and camera is trying to fulfill file size rules which are much smaller

so, all modders pay attention on that! file size limits suitable for max 95% quality:

jpeg min size = 400kb
jpeg average size = 650kb
jpeg max size = 750kb

Raiderski, based on those values, and giving a try on lpachoung driver, this line of code should become into.....?

$c0 08 #SET_JPEG_MIN(01,00) #SET_JPEG_MAX(02,4e) #SET_JPEG_AVG(01,f4)

I hvent checked them yet but according to his tip, it must be like this:

$c0 08 #SET_JPEG_MIN(01,90) #SET_JPEG_MAX(02,ee) #SET_JPEG_AVG(02,ba) #SET_JPEG_QUALITY

And this from me: cam_data_offset=2;
cam_vf_sync=7;
cam_ss_sync=f;
cam_ss_sync_9=9;
cam_ss_retries=d;
