Hey Francisco,

You have done some wonderful things with this kernel, the phone is lasting 18+ hours!

I have found that the NFC function is unable to turn on. Is this a known issue or not? I couldn't find anything about it in my readings. Sorry to bring it up if it has been covered. I'm using modaco ir8 and this kernel. When it was just Paul's kernel the NFC worked. Any workarounds?

Thanks in advance.

Dimitry.

That's right. I can echo 1 into hotplug_enabled after phone booted, but if I reboot the phone it'll change to 0 again even with the script I posted couple posts back.
[Samsung Galaxy Nexus] franciscofranco:
Thats a known issue from that rom, not my kernel ;)

Ok thanks, I think I know what it is ;)
[Samsung Galaxy Nexus] bebolf:
Just wanna share the result of my battery life thanks to Francisco's fantastic kernel!

kernel: franco.Kernel-nightly #10 (default settings with hotplug enabled)

rom: AOKP build 14

Edit:

mind there were at least two reboots as you can see from the graph ;)

Hi! Been using this kernel for my GNex since build 7 and I have to admit , it's a very fine piece of kernel for our devices . Good job franco. To pay a tribute to your efforts , I went ahead and purchased ur app from market to keep uptodate and utilize features of your kernel thru ur app. The battery is highly improved. I am getting nearly 18+ hours with moderate usage of the screen on for browsing and watching video and playing games.

With last nights update to v10 , I am getting an issue where after I turn screen on to unlock the phone , the screen comes on for a half second and than a semi dark color background overrides the phones screen with black blotches all over , and I have to turn the screen on off like 6 times to get back to normal screen .The screen is operational , but can't see anything other than a semiblack background with spots.

would actually like to see this answered as well.
[Samsung Galaxy Nexus] franciscofranco:
Yes, that's fixed in tomorrows #10.1.

Dalvik cache and cache are completely independent of the kernel, they are not needed to be wiped for a kernel flash.

No, you have to head down to the General section and ask it there, this ain't a "help bootloader" thread.
[Samsung Galaxy Nexus] rafi300:
franco, thanks ! by the way , I downgraded to my previous stable kernel nightly 9, yet still I have the same bug of black screen with blotches in the phone ? Could you kindly explain the phenomenon behind that ? It should of fixed it right?

I meant x% per an hour. I just woke up, lost 5% in 7 hours with WiFi on when plugged in, gps on, 3g on, sync on for all google, hotplug on, scaling between 700-1200, conservative, lightflow enabled.

I don't think this can be any lower, but if you insist, I'll disable lightflow for tonight :p

Btw I think LightFlow CAN cause battery drain, if it's been setup with lots of notifications and each with manual clear. Mine is set for only 6 notification types, and they are active only for 30 or 60 mins.

If you receive 3-4 notifications during the night, the phone has to wake up to change the light's color in every ~10 sec until you clear them, which can take pretty long if you're asleep. :)

But this is only my opinion, I'm not sure it works this way.
[Samsung Galaxy Nexus] ljwnow:
I just noticed that my phone won't utilize 700 MHz much, almost zero. I am using the conservative deamon. Is this normal? And why?
[Samsung Galaxy Nexus] kabauterman:

[Samsung Galaxy Nexus] lamecake:
Hi franco! Kernel is running like a charm! Thanks for your continuous efforts.

Question: did you already include updated omap clock data? And would it be possible to add an extra oc slot? I tried imoseyon's kernel and my phone seems to handle 1,42 fine. Your kernel is better on battery tho :d!
[Samsung Galaxy Nexus] notreally:
+1, downgraded back to r276 and CNA 3.6.5 feels faster. I wish I knew how to provide some hard data, sorry.
[Samsung Galaxy Nexus] Savant:
Don't have that problem with cna or rasbean.
[Samsung Galaxy Nexus] chugger93:
My wifi gets stuck often on 276. Seems more when I get home and leave the phone off for an hour. Turn it back on, wifi never connects. If u goto the settings menu and toggle off wifi, it'll act like it toggles off but doesn't. Reboot fixes the connection issue....dida search in this thread and noticed others reported it but on earlier builds.

Anyways...just figured I'd point it out and see if others had similar issues :)
[Samsung Galaxy Nexus] KJW979:
Ran a comparison of all TCP algorithms, pretty much for me they all ran fairly comparable but got best result with the yeah algorithm. Result was 13Mbs down, almost 20Mbs up. Pretty much all of them gave me at least 10 up and 12-13 down. Gonna stick with yeah for now.

Not entirely sure but I think westwood still came out on top. It definitely felt faster in my tests on both wifi and cell today. veno did okay but didn't seem quite as snappy. illinois seemed to get sluggish at times.

r281:

* No changelog provided is intended because I need unbiased feedback on this new version

Also new updater version hitting Google Play as soon as they refresh the servers:

6.9.3

* To break the ice from the latest 2 Force Close fix builds I thought it would be fun to give a more social aspect into the app. So now we have a Share settings option in the Menu button and lets you share some of the most common, but yet useful, settings with your friends and family via Google+ and other apps. This is just an early introduction of this new feature that I hope to see grow with your feedback and suggestions.
[Samsung Galaxy Nexus] yellowdie:
Awesome! As always, I wish you could give more than one Thanks! Lol
[Samsung Galaxy Nexus] kyokeun1234:
Hmm ok. I'll flash it tomorrow :)

Swyped on my Galaxy Nexus running AOKP with Franco Kernel
[Samsung Galaxy Nexus] yellowdie:
Well, I see we're on 3.0.44. I have no issues so far. Still running 512 fine (I got artifacts up until r277). My wifi connects 0.5 seconds faster (consistently 8.5 seconds vs 9.0), but not huge--may be a fluke. Honestly, for the first time it feels a TINY bit choppier. Normally its amazingly smooth, this time I have an occasional little micro lag but only if I am actively looking for it. So far it looks great! I'm gonna run it more and see. :) Thanks!
[Samsung Galaxy Nexus] osm0sis:
I agree. Using my usual settings (which had things ridiculously smooth on r277) it now feels a bit more sluggish out of the gate with r281, for example, in the app drawer. Once all icons are loaded both perform equally well, of course, but r277 seemed to handle the initial icon loading(?) more fluidly. Definitely a bit more consistant microlag in swiping homescreens as well.
[Samsung Galaxy Nexus] yellowdie:
Man, Os, you are always on this thread--it's like you live here. Yeah, I guess I do, too. :p ;)

And I totally concur. The app drawer and the settings page, but most clearly when changing pages in Nova Launcher.

[Samsung Galaxy Nexus] osm0sis:
I check it on my phone at lunch at work, and again in the evening while I'm doing other stuff for school or watching tv. The quote a few pages back about checking "that kernel gpl franco thing" more than facebook definitely applies to me too :p

Stock launcher here, btw.

I randomly stumbled on decompiled code of franco's updater (earlier version, don't ask me where since I don't remember) last week when I was hunting for all the undocumented sysfs commands and I believe all it did for that option was delete the log file so it just doesn't exist for boot.
[Samsung Galaxy Nexus] franciscofranco:
Do this:

echo 300 > /proc/sys/vm/vfs_cache_pressure

Does it help or not at all?
[Samsung Galaxy Nexus] J-Hop2o6:
You want us to blindly flash it :eek: lol. But i see some reports above saying its a bit choppier.
[Samsung Galaxy Nexus] yellowdie:
Same here. :)

And most apps feel fine and snappy. Really, it's mostly the launcher (Just Nova, I don't have the stock installed) and the settings that I can see the lag. Shoot, I'm gonna take my own advice I gave someone earlier and reflash it again. lol. Could be a bad download (I did autoflash the first time).
[Samsung Galaxy Nexus] franciscofranco:
Run the command I posted 2 posts ago please.
[Samsung Galaxy Nexus] osm0sis:
I'm going to go with option c) made it worse? ;)

Now even on the preloaded icons the app drawer lags. Homescreens also seem slightly worse.
[Samsung Galaxy Nexus] yellowdie:
Actually, it feels like it does help! I'm rebooting and gonna set the phone down for a min then come back to see if it's placebo. :) brb!
[Samsung Galaxy Nexus] franciscofranco:
Takes a while to build all the cache etc. Let it run for a while.

After the reboot the value will be back into default.
[Samsung Galaxy Nexus] yellowdie:
Yep! On it!

Interesting. lol

Franco, when you say echo a command, would it do the same thing to open the file in a root browser and edit it manually? I install Terminal to echo what you said, but I'm more comfortable making the change manually.

---------- Post added at 11:20 PM ---------- Previous post was at 11:19 PM ----------

lol, I just discovered that. :)
[Samsung Galaxy Nexus] chugger93:
So like I said previously I'm still on 276, and not only does the wifi still stick, but my speeds seriously don't show up like they should. Screenshot attached. I'm literally 15 feet from my AP, and I should have at least 48 or 54Mpbs, not 11. It was 5, but went to 11 when I took the screenshot, and went back down to 5.

THose values never indicated the correct ones for me. Not even in the 240 series either... so weird. Granted I'm not on the latest build here...but I'm surprised noone else has noticed something like this. Unless of course I'm the only one derping here! lol
[Samsung Galaxy Nexus] yellowdie:
Whoa! I just got a SOD. I haven't had one of those in a long time! lol Pulling the battery now. :(
[Samsung Galaxy Nexus] osm0sis:
Must have been the cache rebuild, like you said. Now I think it's roughly the same as before the tweak (ie. app drawer quick once loaded, homescreens feeling slower than r277).
[Samsung Galaxy Nexus] KJW979:
Not noticing any lag in r281, everything seems to open and close instantly. Ran Netflix and Hulu plus with no problem. Even settings doesn't seem to lag. Running it at 1305/384 with dynamic interactive.
[Samsung Galaxy Nexus] yellowdie:
Wow, HUGE difference. I had lag, checked the /proc/sys/vm/vfs_cache_pressure file and it was 100, changed it to 300, no lag, changed it back to 100, HARDCORE lag. When I manually set it to 100, the phone feels like I'm crawling. lol. I don't know why manually setting it to 100 and defaulting to 100 would make sure a difference. :cowboy:

EDIT: Okay, I don't know what I broke, but now manually setting it to 300, its still lagging like crazy... :/
[Samsung Galaxy Nexus] osm0sis:
That's probably the cache rebuilding like franco said. I assume it does that every time you change the value.. also why I initially thought the tweak made it worse. Give it a minute. I'm trying again now too.

Edit: Seems a bit better on homescreens with the tweak, but still microlags more than r277 when the swiping animation slows (beginning/end).
[Samsung Galaxy Nexus] franciscofranco:
Guys keep testing and reporting, Ill check them all in the morning.
[Samsung Galaxy Nexus] RoscoeDpG:
i been running it since he posted the new build and seems to run just as smooth as 277 i dont see any diff, yet anyway
[Samsung Galaxy Nexus] osm0sis:
Yeah bed time for me too. I maxed out my mobile data for the month (1 week left) dicking around with the TCP algorithms today, but I'll check in at lunch from work if I can lift the wifi password off one of the machines. ;)
[Samsung Galaxy Nexus] chugger93:
I decided to take it for a run...just got done building dalvik and whatnot. Seriously my phone feels snappier then ever. I once had lag using nova, exiting apps and swiping real quick, and don't see it now. Granted its pretty earlier to tell, but god dam I'm liking it!! I'll test more tommorrow morn
[Samsung Galaxy Nexus] momomok:
r281 seems to fix the rare memory leakage under CNA3.6.5

and it is so DAMN smooth!! The app drawer is a bit laggy... I will try the command and see if it helps
[Samsung Galaxy Nexus] evostevo1:
No lag what so ever. I'm using nova launcher with arhd 6.1.0. Kernel app is set to 1305 MHz and interactive governor.
[Samsung Galaxy Nexus] yellowdie:
Okay, so obviously patience isn't my strongest skill. But I did a fresh install of r281, still had lag, echoed 300, and then set my phone down for five mins. Like magic! Super smooth, no lag! :D

I've been blessed with nearly perfect kernels from you since I got my Nexus. I guess it's about time I have one of those "problems" I've seen people mention! lol. But everything looks great now! Running smoothly. I'm also heading to bed. I'll follow up in the morning as well. ;)

[Samsung Galaxy Nexus] Hungry Man:
Been using the latest nightly for a few minutes. I don't notice anything lagging more than usual or any big issues.
[Samsung Galaxy Nexus] Ringo.C:
Running smoothly,,, still keep on testing:fingers-crossed:
[Samsung Galaxy Nexus] Culex316:
When I first flashed r281, it was noticeably a bit slower than r277 even at interactive with hi speed at 1228Mhz, min 384mhz, max 1536mhz, hi speed load at 85..but as soon as I did that command it was a bit more responsive..it even worked on my laptop running Ubuntu...now it's noticeably snappier.

So yes, the difference is somewhat noticeable, is this supposed to have a negative effect on battery life though?

Edit: by setting it at 500 I get awesome performance in games asphalt 7 ran more smoothly than I can recently remember

this new nightly also runs a bit cooler and did you do something to he sound? Maybe I am smoking crack but when playing a game I noticed the sound quality is better.

[Samsung Galaxy Nexus] nuwan32:
Just changed it to 1000 and gta 3 feels smoother. Might be just me. But I read up on this and apparently it has to do with oom values and higher it is the more aggressively higher your cache would be.
[Samsung Galaxy Nexus] fclifton:
I tried this with an app named Terminal Emulator. The response to the command is:

/system/bin/sh: can't create /proc/sys/vm/vfs_cache_pressure: Permission denied

Using Root Explorer I can see that the file exists, and it has the value 100 in it.

I'm not too familiar with this stuff, wondering what I am doing wrong?

You can make a script with that command, and let it be execute after boot. franco's kernel supports init.d I think, so somone (not me, I am using Rom Toolbox for that.) will hopefully tell you where to put it in order to be startet during or after boot.

You could also install Rom Toolbox or System Tuner, they both have 300 as default setting for vfs_cache_pressure.

[Samsung Galaxy Nexus] dandwhelan:
Very fast!
[Samsung Galaxy Nexus] momomok:
OK. so here's some thought about r281:

- battery is good (I got a solid 2h 34min screen on time - good enough for me)

- DAMN fast, feels like my Nexus just turo-charged itself

- vfs_cache_pressure tweak shows no major difference

- my Nexus become very laggy whenever my devices got disconnected (mobile data/Wi-Fi), it would be working normal once it reconnects
[Samsung Galaxy Nexus] zenzip:
franco maybe a noob question:

the choice of different TCP Congestion Avoidance algorithm from default (cubic) can affect on battery life?

2nd day of testing 281. Phone is still flying. No wifi sticks yet. Link speed seems to be good here at work. Will keep monitoring though.

Excited to see the changelog one day... maybe not much changed and its just my imagination! Doesnt feel like it tho
[Samsung Galaxy Nexus] timbck2:
I had forgotten about the changes to CORE undervolting in r277 and was still running 384MHz (my phone has never been able to handle 512,I got artifacts and instability). So I decided to try the 512 version of r281 - so far so good as far as that's concerned. I was seeing some microlags until entering the terminal command Franco suggested. Now everything seems much smoother.
