[Sprint Samsung Galaxy S 4 Android Development] JesseAaronSafir:
Thanks for the update. I bit the bullet and followed [MENTION=2858249]slf123[/MENTION]'s recommendation and upgraded to the latest KT-SGS4 kernel and manually applied all of ktoonsez's own settings. The first thing I noticed is that, as you said, the music stutters when using the ktoonservativeq governor. I switched to "ondemand" and now it seems to be working fine. However, I think many of ktoonsez's settings are specific to the ktoonservative governor so I'm not sure how much of his custom settings I have left. I have in the past tried setting the "Media/Music Min Mhz" to much higher numbers, even almost up to the CPU max and still had music stuttering, which makes me think it's more of a governor issue. I also wonder if it could be an "Internal Read Ahead Buffer" or "External Read Ahead Buffer" or "I/O Scheduler" issue. On mine, I am using "sio" scheduler, as recommended by ktoonsez and I have my "Read Ahead" buffers both set to 2048.

I'm hoping there's actually nothing wrong with KT kernel on this ROM as long as you get the settings right. It's just hard to know what settings are optimal and what is needed to prevent the problems we've seen. Since yesterday afternoon, I haven't lost data at all and I don't think the phone has become unresponsive while charging either. So that's not definitive, but it is encouraging.

Yeah I want to say that this may have been a known issue and the solution is as you said to remove with TB and reinstall from Play Store. However, I've been using Google Voice Search without FC and I didn't do anything to it this time.

Thanks for the update. We need more data points to find out if those settings "fix" the problems. I have several OEM cables and chargers because I invested upfront in two of the official Qi charging pads, which came with chargers and cables. I believe Samsung gave me 20% off accessories when I got the phone so that pushed me to do it. I've had other problems with cheap cables.

Actually, I still have trouble connecting the phone storage to my work laptop via USB, even using the OEM cable. I've been able to get it to work sometimes by removing all the USB drivers and reinstalling specific ones but it's definitely not reliable. It's very frustrating. Most of the time I either eject my microsd card and put it in a card reader and transfer to/from it or I use WiFi Explorer to use WiFi to upload/download to the phone. I have Windows 7 64-bit and my laptop has a number of USB2 and USB3 ports and I have a USB3 dock and a USB3 hub and I've tried many different ports. The computer will know that something is plugged in but says it doesn't have a driver and none of the drivers I've been able to download and install from Samsung or Windows Update make the phone storage show up.

I've been able to use 3Minit alongside with Xposed with no problems. Of course we're all waiting for more of the new 3MinitSettings to be ready anyway. It's not that my Xposed modules go away, I don't think; rather, it's just that the Xposed Framework goes inactive, which causes none of the modules to work.

I have had your experience EXACTLY before where I set the Media and Bluetooth kernel settings to very high CPU and STILL the music stutters. Try using "ondemand" governor, "sio" scheduler and 2048 "Read Ahead" internal and external buffers and see if it still stuttering. I'm on the MF9 firmware and running the KT-SGS4 7/12 kernel just fine. AFAIK, there's no issue running NAE kernels with the MF9 bootloader. I did NOT have luck running the NG2 kernel on the MF9 bootloader as WiFi wouldn't turn on. I also tried the NG2 modem with both the NAE and NG2 kernels and couldn't get WiFi to turn on. So thus far I have not had any luck running any of the NG2 stuff on this ROM (at least with the MF9 pre-Knox bootloader). Anyway to answer your question, I see no reason you couldn't update your KT-SGS4 to the 7/12 version while on the MF9 bootloader. That's what I did and everything is working.
