Really? I find the firewall to be extremely useful in blocking ads from apps that don't otherwise need net access. The SMS/call blacklist is very useful as well, and keeps logs of the texts/calls blocked, unlike blacklist features built into ROMs. It also has file scanning, SMS scanning, and webpage scanning. I'd hardly call it useless.

Yes, there are other ways to block ads. Yes, there are other ways to block calls/SMS. I just think its pointless to bash apps just because YOU don't like them.

First of all, great work on the kernel! Working very well for me so far on 4.3.

I really like the idea of the whitelist (prevents out of memory situations from closing the launcher), and was wondering if there are ways to expand on this functionality? For example, I would like to ensure Navigation, Google Music, and Tasker are never killed. Sometimes one of these three get killed which is quite inconvenient when using it in the car.

I understand not all users would want these processes "exempted" from being killed, so I was thinking if instead it was possible (or if it already exists) to have a init script or a list which the kernel could read. Thoughts?

After reading through the OP and the information provided for the more important features I was very eager to try it.

I've been a f.K user since I got my phone and in all that time, none of the other kernels have been able to provide me with a similar, let alone better user experience (refering to stability and battery).

You have definitely done an amazing job because I'm loving it. I've been able to reach over 3 hours off screen-on time (standard version), which I've never been able to do.

So hats off to you and a big thanks for all the work you've put into this.

Maybe you guys could write a whitelist editor app. It wouldn't be too hard. You might need to signal the kernel when the list changes. Heck maybe just read/modify/write something in /sys filesystem. I personally would not use it. I'm boring, and mostly just want my phone to work.
[Samsung Galaxy Nexus] Taomyn:
Can anyone advise me on this please?

I'm also curious as to why a custom kernel installs busybox to somewhere that can potentially effect the rest of the phone and not place it somewhere specific to the kernel as apps like TiBU do. For example, in my case CM10.2 installs 1.21 (much newer than Fancy), but with a version in sbin the CM version is overridden by the path.

Thanks in advance (8W860563GM935670J).
[Samsung Galaxy Nexus] AbhishekS:
I have some doubts. I know this is basic stuff but I've never tried it and am a complete noob at it.

1. Why do people undervolt? What does undervolting do? How does it affect the phone and the user experience?

2. Is it safe to overclock? Can it damage the hardware?

3. What is zRam? Pros and cons of using it?

4. What are governors? Which is the ideal one for good performance as well as battery life? Or does it different device to device?
[Samsung Galaxy Nexus] sajty:
ad 1) Undervolted device produces less heat and gives more battery life.But if you undervolt too much,you will get freezes/random reboots.

ad 2) Overclock produces more heat,so basicaly it can damage you device,because heat is killer of electronics.On the other hand,if your device is not permanently in high temperatures,overclock should not do any damage.

3) http://xdaforums.com/showthread.php?t=2320734

4) Every governor scales frequencies different way and thats basic difference.For example,interactive is very aggressive in scaling,so it provides (teoretically) the best performance.On the other hand,it will eat more battery.

Busybox is included in the RAMdisk (/sbin) just in case there's no busybox present in the ROM. I just copied an old portable version some time ago from somewhere. Just copying a version included in Cyanogenmod does not work (it's non-portable).

Thanks a lot.

1. Thanks! How do I undervolt? Can I do so using Trickster? Can you suggest an ideal value? I'm not a hardcore gamer.

2. Clear

3. Thanks a lot. I read the first post there. It seems that zRam is not too useful for devices having more than 512mb of RAM. So is it really useful on our Nexus? And how much extra battery does zRam eat on our device as compared to zRam being off?

4. Clear. Can you just tell me which is the best for battery life and basic usage like Browser, Facebook, WhatsApp, Twitter, Instagram, Tapatalk, etc? :)
[Samsung Galaxy Nexus] siealex:
Yes, you can use trickster. Try to decrease all mpu voltages by 75 mV and test your phone. If it does not crash at full CPU load and at all frequencies, try to undervolt 10 mV more. Continue until phone crashes or reboots. Go one step back and try to undervolt each frequency separately. When you find the lowest voltages at which your phone is stable, increase them by 10 or 15 mV and fix.

For Galaxy Nexus' stock voltages are:

350mhz - 1025mv

700mhz - 1203mv

920mhz - 1317mv

1200mhz - 1380mv

So if you dont go above 1380mv, there should not be any hardware damage.

My voltage settings with Fancy Kernel as follow:

mhz - mv

1536 - 1350

1420 - 1250

1344 - 1175

1228 - 1120

1036 - 1050

729 - 900

537 - 850

384 - 775

192 - 720

For sure it is hardware dependance, especially for the 192Mhz voltage, which is the freq. that phone usually sleep with, if you set it too low, you may be not notifiable the phone is freeze already when it sleep. For me, I tried 710 mhz before but it freeze so I +10mv to 720mv and it running fine now. You have to find the best voltage for your phone.

I sorted out the busybox 'problem' by moving the busybox binary to a subfolder in /sbin (/sbin/binaries).

Also, I built a stripped-down 1.21.1 binary myself that only contains the necessary tools needed by the startup script. This way, the kernel image is a few hundred kilobytes smaller :)

I'll release r39 as soon as Linux 3.0.92 is out.

You don't need to remove it - it is already gone by the time you flash the new version. That's because the contents of the /sbin folder are all from the RAMdisk, which is included in the kernel image file.

r39 and Fancy Updater App

Hi all,

good news: r39 is uploaded. Some minutes ago, WiFi was broken with the 3.0.92 kernel release, but minutes after, 3.0.93 was released with the fix. So.. Here you go! Change log:

updated to Linux 3.0.93

SIOplus i/o scheduler: tweaks for snappier experience

Revert "Input: Send events one packet at a time" (broke PGM compatibility)

writeback journalling for /system, /data and /cache partitions (supposed to be a little faster; there's an 'unexpected' reboot on first boot after flashing a ROM / clearing cache!)

RAMdisk: remove redundant 'zipalign apks on boot' function

RAMdisk: remove redundant 'trim all partitions on first boot' function

RAMdisk: remove FUSS updater script due to URL-resolve-problem that came with Android 4.3 (Big thanks to gwindlord for writing it!)

some tweaks 'under the hood' regarding memory and DSS (check git if interested)

RAMdisk: upstream updates from CM10.2

RAMdisk: replace old busybox binary with a new, stripped binary that mostly has only the coreutils included and therefore is enough for the startup script

RAMdisk: move busybox binary to /sbin/binaries, so it won't interfere with the system's busybox

Also, Parthipan Ramesh wrote an app to update Fancy Kernel! I could not be more amazed and am happy to provide the apk in the OP in the download section. The app will check for a new fancy version on every boot and will give you a notification. Other than that, it checks every 5 hours for an update. The updater app is in an early stage and still misses additional functions. But the author assured he's on it :) Also, the app will be on PlayStore soon.

Have fun!

fstrim for /data only takes 5-10secs for me and about a seconds for system. Really enjoying r9 kernel on orca with everything stock except undervolting with mpu off, regulator undervolts, and custom display settings. :good:

Just a sidenote, I tested out the new AIR kernel before flashing fancy and couldn't boot, tried flashing stock kernel and other kernels. I'm not sure what happened after using AIR kernel, no crashes or anything like that, but I thought I would mention it in case anyone's having trouble coming from air kernel. I ended up flashing Rom and gapps back over to get the system back to normal.
[Samsung Galaxy Nexus] gwindlord:
That might be happen due to some kernels use ROM's ramdisk, and the other ones have their own. So if kernel of 1st type will be flashed over one of 2nd type, this would lead to bootloop. That's why it is recommended to flash any custom kernel over ROM, but not other custom kernel.

One second is short, but it is annoying, because I often switch of the screen by mistake, and it's long to wake up the device.

Lagfix requires 'Superuser Permission'.

Which, it seems your phone is denying. I've had Superuser do this 3 different times, it corrupts, won't respond, then just auto denies, so it looks like the app doesn't function, if you aren't paying attention.

Superuser is garbage software, and I'm amazed it's still in use. SuperSU and there is the port of the MIUI Security done by a fellow from Australia(I'm using it on a One V with 4.0.4, replaced Superuser), really prefer the MIUI one to even SuperSU, but it's a bit of a work in progress.
[Samsung Galaxy Nexus] SaskFellow:
Basically, because flash memory doesn't automatically delete the data that is stored in it's cells when the operating system deletes the data from the file-system, more data can't be written to the cell before it's emptied. This problem didn't exist with good old fashioned HDDs because they could just simply overwrite the sectors that were considered 'free space'. In fact that's why deleting files is so fast, because the OS is simply removing the references to the data, rather than actually deleting the data, unless actively install and use programs that 'wipe' the data from the disk. So this is where TRIM or fstrim comes in, it runs a basic scan and any of those blocks that should be free but aren't get set to empty, so they can be used.

In very simple speak, it's basically a garbage collection routine, it comes along and cleans up the litter so that the system can use the space more effectively and efficiently. It looks at the map and simply queries all the blocks that should be empty, if a block isn't, it tells it to empty itself, leaving it open and available.

Now there are downsides to using it too often, because flash memory does wear out over time. Though, that is leveled off somewhat, in that it allows the load balancing(so all the cells get used evenly) to work more effectively.
