If you just enable zram but didn't setup vm.swappiness (since vm.swappiness by default is 0%, mean no swapping), zram will not working properly (and may cause problem?)
[Samsung Galaxy Nexus] Astug:
Had a random reboot last night on r40ext, settings: interactive, cfq, ZRAM on through Trickster (had to enable it, reboot and enable again to get it to work).

I was using the 9GAG app, then went to the homescreen and opened Chrome, the phone froze and rebooted.
[Samsung Galaxy Nexus] d0ge01:
Strange issue about SR, i'm not sure if trickster display bug or real...

This is my voltage used by SmartReflex

192mhz - 820 mV
350mhz - 840 mV
535mhz - 835 mV

So , 350 mhz use more power of 535 mhz step, so, i'm using 535mhz as min as well without any problem in battery drain ( and without any battery drain advantage, 5mV is too low to be noticed).

Boype, 192mhz and 535mhz are calibrated with SR too, or this addicted step use static voltage ?
[Samsung Galaxy Nexus] siealex:
Try to disable SR and set 735, 780, 840. Will it freeze or reboot?

[Samsung Galaxy Nexus] d0ge01:
Already done this test many times

384 is stable with 800 mV

192 is stable with 750 mV

535 is stable with 835 mV

my question is , are all this step calibrated with SR? is SR "bug" ?
[Samsung Galaxy Nexus] r3act:
Stable 40 this morning picked up the phone off of my desk and had to enter SIM-PIN, thus a reboot overnight!

Stock kernel flash with dalvik and cache wipe on CM10.2 I don't even mess with ZRam or anything else.

It seems to happen with cfq sheduler (which I always set to keep the stock CM feeling) sioplus seems ok so far...
[Samsung Galaxy Nexus] wasdf:
Try to use deadline instead, afaik cfq quite buggy (please search cfq on franco's kernel thread, they have discussion before, and franco tried to use different version of cfq before but as i remember some members still reporting random reboot)

Guys my phone overheats even when using browser or messaging is this normal? Runinng newest fancy kernel and paranoid rom
[Samsung Galaxy Nexus] daniil1410:
I've been using r40 for ~20 hours. My importation is that is very battery hungry. r40-2 was way better. Can someone confirm?
[Samsung Galaxy Nexus] JBNex:
No it's not. Try changing the CPU governir to Interactive
[Samsung Galaxy Nexus] d0ge01:
Where do you live?

Little overheat ( max 60° ) is quite normal in summer , when except 60-70° it 's not normal

Are you using SR right?

Are you using interactive ? ( interactive seems IMHO overheat more than ondemandplus )

Are you using cfq or sioplus? ( these are know as "not stable" scheduler )

Are you using overclock? ( overclock cause overheat )

If all this answer is false, set in trickster -> governor control : interlow_freq = 535000 , interhigh_freq = 750000 ( not sure is 750mhz , too lazy to see myself )
[Samsung Galaxy Nexus] john317:
Where do I find the settings for it?

---------- Post added at 12:56 PM ---------- Previous post was at 12:55 PM ----------

Actually I don't know where to find the settings for it sorry quite a newbie
[Samsung Galaxy Nexus] Astug:
That's true, I actually remember that.

Though, CFQ is the stock governor, right? Have these random reboots been reported on stock rom/kernel combo?

Is the one in Fancy a modified version?
[Samsung Galaxy Nexus] Sik-1:
Download trickstermod from the play store and your good to go
[Samsung Galaxy Nexus] john317:
OK thank you what are the beat fancy kernel settings for Samsung Galaxy nexus?
[Samsung Galaxy Nexus] Starsream88:
R40 update is just AWSOME !! Great speed and performances, never had such smooth experience ! Great work [MENTION=4615478]boype[/MENTION] thank you

Some useless bench, but the score is improved :
[Samsung Galaxy Nexus] pkgnex:
You guys are confusing CFQ with BFQ. BFQ v6 has had stability issues, CFQ is the stock scheduler and is probably the most rock-solid choice for stability (although Deadline is close).
[Samsung Galaxy Nexus] lparcshinoda:
Shouldn't this info be posted (with some guide or such) in the OP as advice? [MENTION=4615478]boype[/MENTION]

Anyway... how much swappines do you think is good?

This is NOT normal. I'm on r40, everything stock but the min screen on to 192, max to 1036. I leave my phone plugged in overnight, every night, and it sleeps like a baby. Using Slimbean Beta 3.
[Samsung Galaxy Nexus] stevensoaj:
Did you guys read the changelog? Swappiness is set to 50 by default, not 0. Mine is also not set to 0, and I have not set swappiness manually. You're both on r40ext right?
[Samsung Galaxy Nexus] Astug:
Correct, my bad. Should have searched franco's thread myself.

Though that means that the random reboot I had on r40ext is caused by sth else, but what? Ö
[Samsung Galaxy Nexus] boype:
I won't do any undervolting 'out of the box' ... That's up to you guys :)

Actually, only the 384, 729, 1029 and 1228 MHz are really smartreflex calibrated. The other steps just use the value of the closest previous sr-calibrated frequency and apply an additional static margin on top of that. So, all of the frequencies are somewhat dynamically calibrated by sr, but only four frequencies are truly sr calibrated.

I think zRAM uses quite a bit of additional battery

Is that a rather large improvement? I'm not really following any benchs...

What stevensoaj said :)
[Samsung Galaxy Nexus] lparcshinoda:
So to enable ZRAM I don't need any int.d script? Correct?

[Samsung Galaxy Nexus] splus:
40ext was really, really hot for me, whatever app I used.

I had to temporarily flash the stock kernel (Cataclysm ROM), just to get by through the day.

Interactive with hispeed freq at 729, tried both BFQ and Deadline, no Zram.

I haven't had any heating problems in previous releases.
[Samsung Galaxy Nexus] Pkt_Lnt:
How true. :(
[Samsung Galaxy Nexus] daniil1410:
Possibly. But, in my opinion, 40-2 with ZRAM was better.
[Samsung Galaxy Nexus] AbhishekS:
My phone charges really slowly. It can take 5-6 hours or even more to charge fully.

Can it be related to the fact that the phone doesn't enter deep sleep while charging?
[Samsung Galaxy Nexus] siealex:
No, check your charging adapter and USB cable. My phone charges 2.5 hours with screen always on.

[Samsung Galaxy Nexus] Seraz007:

[Samsung Galaxy Nexus] parkson:
Hardware issue - phone only charges at USB rate, no matter which charger/cord combo you try. Same happened to me and Verizon had to replace the phone.
[Samsung Galaxy Nexus] AbhishekS:
But when I flashed back to 4.2.2 everything seemed to be fine. Could be a placebo and I was on 4.2.2 for merely 2 days, so couldn't get time to verify it either.

But it isn't a placebo on 4.3 for sure as I'm repeatedly facing slow charging speed.

Going to Settings->Battery says 'Charging (AC)', so is that all I need to check or could it be that even though it says 'AC' it charges at USB speeds. And if that's the case then how do I check the ACTUAL charging speed value?
[Samsung Galaxy Nexus] Blackcrx:
Check the output current on your charger. Also try another charger.
[Samsung Galaxy Nexus] AbhishekS:
It's the original Samsung charger.
[Samsung Galaxy Nexus] Blackcrx:
Try a different USB cable? How long is the cable?

The longer the cable, the slower the charge.
[Samsung Galaxy Nexus] AbhishekS:
It's the original cable too. :p

And I have no extra charger or a cable for a few days at least.
[Samsung Galaxy Nexus] bittermormon:
I have a hard time believing that a 6 or a 3 foot cable charges any slower than a 1 footer without any sort of proof.
[Samsung Galaxy Nexus] siealex:
Check the data pins on the USB cable and on the device. If they are damaged the phone will charge slowly. Also check them on the charger, they must be connected together.

---------- Post added at 08:29 PM ---------- Previous post was at 08:28 PM ----------

Too long cable can prevent the phone from recognizing the charger as the AC adapter. I had the same problem on Asus P750.

Anyone having wifi drops on r40?
[Samsung Galaxy Nexus] Blackcrx:
Might not be as noticeable comparing 6' or less cables. I have a 12' cable I use.

Longer the cable, higher the resistance, less current.

Same reason why USB1/2/3 all have different max length specs
[Samsung Galaxy Nexus] TinyFeather:
Whooo, r40 rocks! :D

Thank you so much!
[Samsung Galaxy Nexus] bittermormon:
I understand that theoretically it could slow it down but I can't see it being a real reason why his phone would take 3x as long to charge.
[Samsung Galaxy Nexus] Blackcrx:
You're right. I simply suggested that he try a different USB cable. I've had USB cables that have gone bad and took forever to charge and transfer data.

Also some ppl aren't aware that longer cables or even different quality cables change charging speed.

He could have swapped cables and not known about it
[Samsung Galaxy Nexus] AbhishekS:
Woohoo!! Battery Widget Monitor Pro was showing charging speeds ranging between 192mA to max 500mA.

Just borrowed a friend's BlackBerry USB cable. And now the charging speeds are above 800mA and sometimes around 1100mA. So the cable was faulty!

Problem solved!!!

One last doubt though. Can using a Blackberry USB cable to charge my phone daily damage the phone's microUSB port?
[Samsung Galaxy Nexus] Blackcrx:
Boom!! bad USB cable.

Doesn't matter what USB cable you use. They're all standard micro size fit.

I would suggest getting a name brand one as opposed to cheap eBay ones tho.

As mentioned the cable size could be different thicknesses which affect charge speed and data transfer speeds.

Not to mention some of the cheaper USB cables have poor fitment and could damage the actual USB connector on your phone
[Samsung Galaxy Nexus] cmoG530:
BlackBerry is fine. I'm using one and it's really durable and the charge time is great.
[Samsung Galaxy Nexus] AbhishekS:
Well the last statement has frightened me a bit. But as the [MENTION=2011394]cmoG530[/MENTION] says, Blackberry should be fine I guess. :)
[Samsung Galaxy Nexus] RNZart:
yupp, no problem at all...I've been using BB cable on my last 3 phones :silly:

I also seem to be chewing through battery with r40 compared with previous versions with the same settings.
[Samsung Galaxy Nexus] chikimonke:
With or without zram enabled? Per [MENTION=4615478]boype[/MENTION] post earlier, zram might be a bit battery hungry.
[Samsung Galaxy Nexus] thomstrack:
Same here! (without zRAM enable)
[Samsung Galaxy Nexus] d0ge01:
Yes sir, your are theorically right but a cable with a 5 cm difference can not cause problems , only USB work good upto approximately 5 m ... it's not real problem on our phone, damaged cable can cause this issue, but 5 cm different lenght can't cause any issue .

I had this issue with damaged cable ( 1 of 5 pins have been damaged ) , to resolve this issue try with stock AC adapter with different cable ( any USB-Mini USB - B is good IMHO )
[Samsung Galaxy Nexus] DaNi_!:
Hi all!

I'm proud to be the designer of the new fancy kernel logo :). I made a signature too (actually the same as the previous one, but I made some changes to the circle). For the ones who are interested in having a logo of the best kernel for Galaxy Nexus in their signature, here it is:

Its with zRAM enabled, but I've always had zRAM enabled. The battery drain is higher on r40 though.

[Samsung Galaxy Nexus] ChazzMatt:
RE: Nexus 4 price cut

What is there to talk about? Nexus 5 is coming in October/November. We've hung onto our Gen3 Nexus until now -- might as well wait another couple of months. :cool:

I'm not spending $250 now on a 1-year old Nexus 4, and the spend another $350 in a couple of months on a news Nexus 5 -- and then have to get rid of TWO old Nexus phones (Gen 3 and Gen 4).

---------- Post added at 04:24 PM ---------- Previous post was at 04:23 PM ----------

Keep your Gen 3 Galaxy Nexus for a couple more months until Nexus 5 is released.

Gen 1: January 2010

Gen 2: December 2010

Gen 3: November 2011 (after October announcement)

Gen 4: November 2012 (after October announcement)

Gen 5: November 2013 (after October announcement) < bet on this. ;)
[Samsung Galaxy Nexus] Charmacas:
And again I really have to say that without ZRAM the phone seems a lot snappier. :)
[Samsung Galaxy Nexus] Hoochie_Coochie:
Well to talk about how cheap the nexus 4 is. As the new nexus is clearly gonna be more expensive.

Just a chat about how good a deal this is.
[Samsung Galaxy Nexus] namtombout:
Probably because this is a kernel development thread
[Samsung Galaxy Nexus] Bosio91:
Not to burst anyones bubble, I was considering still on buying a Nexus 4 but is there any facts about the Nexus 5 coming out? And I don't mean this Moto X phone which I wouldn't pay a cent for...
[Samsung Galaxy Nexus] Hoochie_Coochie:
True...sorry to derail
[Samsung Galaxy Nexus] sruel3216:
Feel like r37 is still the best in last few builds
[Samsung Galaxy Nexus] ChazzMatt:
Yes, lots.

1) Google is doing a Nexus 5.

2) Last two years has been released in November, after October announcment.

3) Will come with Key Lime Pie 5.0

4) In May of this year, CEO Larry Page visited LG headquarters in South Korea, where he was shown the prototype (according to LG sources talking to Korea Times newspaper).

5) In July -- a month before the LG G2 was officially revealed, South Korea media outlet Daum published the specs -- which were on the money -- and confirmed the G2/Nexus were on a linked development path. Since they got the G2 specs right, they were talking to LG sources who knew, and that means the G2/Nexus 5 is also confirmed (again).

6) Vietnamese sources where LG has factories says Nexus 5 is coming, based on the G2.

and I hate the Moto X too. But a Nexus 5 on a G2 foundation, maybe even internal fraternal twin like the G/Nexus 4. You betcha.

---------- Post added at 07:24 PM ---------- Previous post was at 07:19 PM ----------

I'm not buying a 1-year old Nexus for $250 (4.7", 720p) to replace my 2-year old Nexus (4.65", 720p). :rolleyes: Not when the new Nexus 5 (5.2", 1080p, Snapdragon 800) is coming for the same price I paid for my Galaxy Nexus, $350.

When you see everyone with the Nexus 5, you will HATE buying the old Nexus 4.

My sister last year bought an iPhone 4S just a month before the iPhone 5 came out. I hate iPhones and told her all the reasons she should get an Android, but she didn't listen -- and since she didn't ask my advice about the iPhone she bought the last year's model at EXACTLY THE WRONG TIME. I couldn't believe it, but she just didn't know any better. EVERYONE knew a new iPhone was coming out with bigger screen, faster CPU... except her. So, she locked herself into a 2-year contract with the "old" iPhone. :)

You buy a Nexus 4 and come November you will want the Nexus 5 instead of the "old" Nexus 4. All the developers will be flocking to the Nexus 5...

Many kernels have an extra CPU frequency 920 MHz. Why doesn't Fancy have it?

[Samsung Galaxy Nexus] wasdf:
you wont able to go extra 920 Mhz unless increasing CPU voltage, but for Stock Voltage (1380mv) it is safe and rock solid to use 1536 Mhz

I believe the reference was to the frequencies jumping from 729 to 1036 without the 920 in between. As for why it's not there, I would imagine [MENTION=4615478]boype[/MENTION] has decided it was unnecessary.

Hi,

here's the attempt to fix the random reboots some users experience:

Kernel image:

http://boypetersen.de/fancykernel43/tst/fancy_kernel-tuna-4.3-pre41-1-ext.zip

The (potential?) fix (if anyone is interested):

https://github.com/boype/kernel_tuna_jb43/commit/24d62e2fdb09d6620f0a151cbeae928424660f78
[Samsung Galaxy Nexus] pcphobic:
[MENTION=501758]zoomy942[/MENTION] Yes, there is a reason.

On some Galaxy Nexus (like mine), we get poor total Screen Usage time (around 1 hour 40 minutes if solely on 3G only) if we use OnDemandPlus.

So we use Interactive and also change the scheduler to either Deadline or BFQ.

I can now get between 2 hours to 2 hours 50 minutes of total Screen Usage time when solely on 3G only especially with certain tweaks to the kernel settings via Trickster MOD app.

Hello I've installed this kernel and works really good by now, but I found my phone really hot in the upper part when browsing with Chrome (then it went cooler when using Tapatalk). I've had the GNexus for a short period of time so I don't know if this is normal or not but anyway it was so so hot.

[Samsung Galaxy Nexus] ChavitoArg:
It seems like every user its complaining about this, but not just here, in every single thread. Check paranoid thread for example. Common if you heavy web browse and your browser use a lot of cpu, plus you are on 3G or receiving a lot of data trough wifi, and with the screen showing reaaally shiny colours IS EXPECTED that your phone gets hot. No phone is safe of overheat, if this heat is far from normal your phone will shutdown itself, get over it.
