[Galaxy S 4 i9505 Android Development] Funky-kun:
I'm coming from stock 4.3, rooted, MKF.

I flashed an older version which I started testing (with good results), but was getting some battery life issues... turned out to be a defective battery. :( Got a new one, installed latest stock ROM last friday, let it settle and tested over the weekend.

I used the following KTweaker settings:

I/O scheduler: ROW

CPU governor: ktoonservativeq

governor adjustments: touch_boost_cpu 810

screen off profile: 810

screen off GPU: 320

I'm still new to this, so let me know if I did something wrong. With this, I managed an Antutu score of 27, 700. Stock KT settings get me to 28, 300.

The ROM feels blazing fast in general use. Gone are all the UI stutters (even with nova launcher replacing the Lagwiz launcher) that plagued the stock Sammy ROM. 3D performance in Asphalt 8 is noticeably better than stock. With the help of Tasker, Smart IR Remote, Lux Auto Brightness, and LightFlow I miss almost nothing from stock.

Except the camera. (known focusing issues, no 16:9, etc.) I tested a few, and it really seems Snap Camera is the best alternative to stock, but the HDR mode is pretty bad... and there is a really big issue I didn't see coming. For the first day camera apps (Snap Camera and Camera JB+) worked as intended in HDR and night mode. However, after that they started behaving the same way as stock - not focusing on touch in night mode and HDR mode. This is a really deal breaker for me. :(

The above mentioned KTweaker settings give a pretty awesome battery life. One night worth of standby, a full day of above average use (including gaming, 45 minutes of music and background sync for a bunch of apps, most notably Dropbox for photos) and I managed 5 hours of screen on time. See screenshots below.

However I encountered some other issues.

For example, when I get calls, the screen turns on a few seconds after the phone starts ringing. Flashed the rom after a full wipe, also did the recalibration procedure, to no avail. Actually I'm pretty sure the issue is not related to the proximity sensor at all, because the same thing happens when the alarm goes off - the ringtone starts, and the screen on lags behind it.

There were a few rare hickups when browsing, and some random stuttering when playing Jetpack Joyride. A few times even the swiping on google keyboard started to lag like crazy. When poweramp is playing (with an ongoing notification), swiping the notification panel is slow as well. I'm pretty sure this is related to my KTweaker settings, so I'll need to work on that. Switched to stock KT settings for now.

On some apps, sometimes the sound seems to have issues. For example, in Candy Crush sometimes the beginning of sounds is cut out ("-vine", "-licious" instead of "divine" and "delicious"). Kernel related?

And last, hen going switching to nova launcher via the home button from some apps (e.g. Clash of Clans), the wallpaper appears half a second after the icons, the background staying black before it happens. I don't remember this happening on stock Sammy.

Does this ROM support the faster charging with the original Sammy charger? Is it ROM related at all? I saw fast charge in KTweaker settings, but it seems that refers to faster charging when connected to USB...

A small suggestion for improving the inverted phone app: in the call log, the call details screen shows the contact name in black font on a semi-transparent black bar over their picture, making it really hard to read. Maybe change the text to white?

Let me know if you guys have any fixes for the above problems or suggestions for KTweaker settings.

And thanks a bunch, [MENTION=4830253]Danvdh[/MENTION], for making this extra awesome ROM! :highfive:
