Hi guys. Just wanted to let you know what this mode is not working the way it is set to work, meaning photo quality is NOT at 100% and LG still snaps 97% compression rating in full sunlight, nature pics saturated with data, landscape. I suspect but not tested yet that low light pics will be 70% compression ratting meaning this mod is just not working. I will verify this. I have LP 5.1, rooted, busybox all working fine, flashed mod, rebooted. Same results. Here is data. Sucks balls. LG is blocking this mod somewhere else not in xml file. Basically 97% is first LG default value camera is using so it's not using modded value but still using default 97,xx,70 default values, meaning mod did not take effect.
Verified camera XML profile is set to
</EncoderProfile>
<ImageEncoding quality="100"/>
<ImageEncoding quality="100"/>
<ImageEncoding quality="100"/>
<ImageDecoding memCap="20000000"/>
However here is analysis of jpge taken with that profile analyzing copmression rating and it's at 97%.
"Approx quality factor = 96.95 (scaling=6.11 variance=1.09)" down below
Compression stats:
Compression Ratio: 6.50:1
Bits per pixel: 3.69:1
Program used, works good before on my G3 which had 100% photo quality. this software was doing 99.6% or something close.
