What recovery [and what version] are you using? What is your s4 mini version? What CM rom are you flashing?
[Galaxy S 4 Mini Android Development] saintetienne:
CMW based v6.0.5.1 , I9195 lte , cm 12 5.0.2 20150415 and 2.2.0 eur ,

cheers
[Galaxy S 4 Mini Android Development] llapao:
I am on latest cm12.1 from [MENTION=3261191]F4k[/MENTION]. Do you flash the kernel right just after the rom? And before that delete cache and dalvik too? And before rom delete data/factory reset?

The only thing I can think to help you is to try cm12.1.
[Galaxy S 4 Mini Android Development] saintetienne:
Yes , same as you describe , I may try 12.1 over weekend ,

cheers

[MENTION=3261191]F4k[/MENTION] I get issues with video, invalid argument stuff. "q blank display" issues. QCD_DISPLAY or such, I didn't save the logcat. I see nothing during and after boot. The phone works fine otherwise. I got this with 2.1.6 (when I tried LP 5.1, your build), and the new 2.2.0 .
[Galaxy S 4 Mini Android Development] Supernico00:
I don't know anything about governers , IO schedulers and all that , what would be a good configuration for a nice balance between battery life and performance ? :3

Thanks in advance ! And great kernel by the way :)
[Galaxy S 4 Mini Android Development] TiTAN-O-One:
In my opinion, Smartmax for governor and Fiops for I/O. So far, gotten 4 hrs screen on time on battery with like heavy use of Whatsapp and social media + browsing.

Clocking ur cpu to 810mhz is enuff perfomance to kick some butt when gaming. Asphalt 8, lowest graphics, run smooth.

Oh, make sure u undervolt ur CPU
[Galaxy S 4 Mini Android Development] Supernico00:
How much can you undervolt on the S4 mini ? Before it starts to be unstable :>
[Galaxy S 4 Mini Android Development] wout.vde:
I've been on latest kernel and rom for a few days , and i'm experiencing just a few issues.

First , youtube video's seem to lag in the beginning of the video , it plays correctly after a few seconds. Some other video's on random sites seem to lag the phone a lot when trying to scrub through the video.

Second , trying to use audio usb devices lags out the phone untill it eventually crashes.

Anyone had any luck with audio usb devices ?
[Galaxy S 4 Mini Android Development] zorglub!:
On a previous Rom, cm12 based, I undervolted all frequencies -100mv and it worked fine.

Min freq was 162Mhz BTW and the phone woked up like a charm !!!

[MENTION=3261191]F4k[/MENTION] : a few french users complained on a forum I use that your kernel was not working... because they were confusing between 5.0 and 5.1 versions. As they exactly have the same file name since version 2.2.0 I suggest that you refer the lollipop version in filename to prevent further mistakes like that. Maybe it happens a few times all over the world :)

Big regards,

hi

Hello i can install this Kernel on RESURRECTIONREMIX ROM my phone is 3g dual chip
[Galaxy S 4 Mini Android Development] kyrillos13:
A comment on the sidenote.

I recommend you Samsung 850 Evo series (TLC cells). Its the best SSD IMHO if you want to have only your operating system on your SSD. If you wanna compile builds everyday on SSD (=high number of GB written everyday) then you should look for Samsung 850 Pro series (MLC cells), which can handle 3+ times more terabytes written before wearing out. Maybe you know these already, maybe you don't. Anyway, make your choice and enjoy.:good:
[Galaxy S 4 Mini Android Development] F4k:
Samsung 850 series are too expensive, Crucial MX200 have Micron MLC flash type, do you think that I should choose the Evo series over the MX200?
[Galaxy S 4 Mini Android Development] kyrillos13:
Hmm then i think you should go for MX200. Its at the same price as evo, but MLC cells. Go for it!
[Galaxy S 4 Mini Android Development] jnvdh06:
Hey guys. Dont know if you know about this app, but Aero Control from Play Store is awesome to control kernel settings etc. Try it.
[Galaxy S 4 Mini Android Development] tostep:

Which partitions can be formatted with f2fs? System, data and cache? I ordered a S4 mini and want to do a clean fresh install of f4ktion CM12.1 kernel and ROM, and format all possible partitions to f2fs. Is the twrp-f2fs version in the f4ktion download folder also able to handle ext4?

Thanks a lot.
[Galaxy S 4 Mini Android Development] s.goten:
I'm try this kernel and it works fine. Thanks F4k. :good:

Just a question: I have tried performance control app to modify voltage settings but app don't works. (FC when in voltage settings tab and also in other tabs).
[Galaxy S 4 Mini Android Development] F4k:
This kernel supports F2FS on all partitions, I mean /system, /data and /cache.

But warning, if you format /data as F2FS all your internal sd card will be formatted, make a backup first.

2.2.0 for i9195 is not working

Hi.

Kernel 2.2.0 is not working with CM12 nightly 25/04 on i9195. Trebuchet continuously crashes.

Thanks for your attention.
[Galaxy S 4 Mini Android Development] ghuertasw:
C'mon! At least read the thread's title... There's a new kernel update.

Try it! ;)
[Galaxy S 4 Mini Android Development] hawaianas:
Hi.

The kernel update you're referring to (2.2.6) is for CM 12.1 (LP 5.1) not for CM 12 (LP 5.0).

As you can see on F4k's files Basket Build

https://basketbuild.com/devs/F4k/kernel_f4k-lp/eur_lte/#

There is no update for CM12, while such update has already been released for LP.5.1/CM 12.1

https://basketbuild.com/devs/F4k/kernel_f4k-lp/eur_lte/lp-5.1

Byez.
[Galaxy S 4 Mini Android Development] ghuertasw:
Oops! I'm sorry, I thought the new release was valid for both 5.0 and 5.1... :o
[Galaxy S 4 Mini Android Development] hawaianas:
No problem mate ;)
[Galaxy S 4 Mini Android Development] zarolio:
I just clean flashed CM12.1 and f4ktion 2.2.6. Everything works great.

Thank you F4K.

I have just a couple of questions. Is the hardlimit file no longer necessary? I tried to flash it and it led to a disaster, but without it the cpu freq jump back to default (i use kernel adiutor). Also i can't find interactive governor for GPU.

Thanks in advance.

a little question

to connect an OTG device , the notification icon appears for an instant and leaves.

Is it possible to configure it to stay active ?

thanks
[Galaxy S 4 Mini Android Development] zarolio:
As i posted a few days ago, i recently clean flashed CM12.1 and f4ktion 2.2.6.

Everything works great, but i cannot oc the cpu. The cpu freq jumps back to 1.728. I ve used Kernel Adiutor (and other apps) with no success. Performance control app keeps crashing.

Also flashing the hardlimit files caused bootloop.

Any suggestions? Am i doing something the wrong way?
[Galaxy S 4 Mini Android Development] sasank360:
Even I tried those hardlimit files on 2.2.6 f4k kernel for I9195. They did not work for me.

May be they are incompatible with latest versions of this kernel.
[Galaxy S 4 Mini Android Development] zarolio:
Thanks for your reply. I thought i was the only one having this problem.

So how do we oc the CPU?
[Galaxy S 4 Mini Android Development] sasank360:
I do not know :confused:
[MENTION=3261191]F4k[/MENTION] How can we overclock cpu on latest kernel ? Hardlimit files do not work.
[Galaxy S 4 Mini Android Development] F4k:
For me work's fine, I'm using OC at 1.94GHz

You can OC using PerformanceControl app too.
[Galaxy S 4 Mini Android Development] zarolio:
Thanks for your help.

I ve tried performance control. It crushes all the time. I ve tried other apps too (kernel adiutor, tweaker etc) with no luck.

CPU frequency always jumps back. I ve checked from the CPU statistics.

It seems like the hardlimit cannot be broken.

I be done a clean install of cm 12.1 and kernel 2.2.6.

Any ideas would be appreciated.
[Galaxy S 4 Mini Android Development] racht:
I am using kernel adiutor as someone posted earlier, u can grab it here : Kernel Adiutor

Hey [MENTION=3261191]F4k[/MENTION] is it possible to virtualize storage on a smartphone? It would be grate if instead of an internal and an external memory there will be only one big memory!

hi, if i flash this kernel on s4 mini lte(cm 12) do i have to wipe data(and others, of course), and to reinstall xposed adn walkman?

sry for my question and for my english :)
[Galaxy S 4 Mini Android Development] Pangadaywalker:
I didn't. I only wiped what was asked Cache and Dalvik.

And I didn't re-install the xposed app. Already there. Only re-install on ROM updates.
[Galaxy S 4 Mini Android Development] andrei_david7:
second questin: i have changed bootanimatin on cm 12, and after flashing this kernel, when i power my device on, it shows ''set warranty bit:kernel sgs4 mini gt9195 '' and after that, a black screen, nothing else. what can i do?

le. the phone is ''working'', somehow, because it's overheating(~39 C)
[Galaxy S 4 Mini Android Development] Pangadaywalker:
Ok. This is the second time it happens to me and not sure if only me but look at both images:

USING PHONE:

CHARDING:

Battery simple drops from 60% to 25% with no reason. And when charging it jumps right back to 60% after couple minutes.

Anyone had this issue before?

Deleting the BatteryStats from the system folder would help in this case?
[Galaxy S 4 Mini Android Development] llapao:
For me the first that's a symptom of a random reboot... you have a reboot, after boot you get a different (but real) battery %.

The second, for some reason the CPU is locked, or deep sleep was prevented by an app.
[Galaxy S 4 Mini Android Development] Pangadaywalker:
Actually of that happen in 2 minutes more and less. I reboot get the 25%. I go ahead put in the outlet and within minutes it is back to 60%.

I delete the batterystats.bin and used some apps for battery calibration. Let's see if that will help. :silly:

Also again delete cache and dalvik. Hope this stops. It is pretty bad not to be able to trust your phone. :laugh::good:

Kernel needs an update , makes system UI constantly crash on CM12.1 14 may build (using team UB rom)
[Galaxy S 4 Mini Android Development] GNUDroid:
sure? I'm asking because I read on system ui crashes in recent cm 12.1 nightly -/independent of the kernel. see official cm 12 thread.
[Galaxy S 4 Mini Android Development] Supernico00:
Yeah , cause it works fine when I flash the rom but then when I flash kernel it doesn't boot, system ui keeps crashing

It sucks, because stock kernel has god awful battery life :/
[Galaxy S 4 Mini Android Development] Pangadaywalker:
[MENTION=3911413]Supernico00[/MENTION] is right. My S4 Mini and S5 both doesn't work with any custom kernel even after 1305.

So kernels will need to be updated. I am pretty sure F4K is already woking on it.
[Galaxy S 4 Mini Android Development] Tirofog:
Same, system ui crashes here on official 12.1 nightlies since 13th with this kernel.
[Galaxy S 4 Mini Android Development] Pangadaywalker:
Has anyone tried the kernel lately? Is it ok with i9192 nightlies?
[Galaxy S 4 Mini Android Development] csendre:
There were no updates so I don't see why would it work. Hope everything is OK with f4k, he hasn't posted anywhere since May 8th.

Dear friends, Lollipop update for our S4 mini has been canceled due to memory limitation.

If the reason truly was due to memory limitation, how does a device such as the SM-G360F which has the same amount of internal memory (8GB), and even has LESS RAM (1GB while the S4 mini has 1.5GB) still be able to get an update and offer an optimal user experience. Let's not forget that Lollipop itself was supposed to be a more optimized version of Android.

*This is a P E T I T I O N to show how many people use Samsung's Galaxy S4 mini who want to This is a petition to show how many people use Samsung's Galaxy S4 mini who want to see the update on their device.

nevertheless we should simply wait, maybe simply busy with real life things.

Ty! I like your ROM and kernel!

Working perfectly!
[Galaxy S 4 Mini Android Development] andrei_david7:
And, if it is possible, can you modify screen sensivity to work with pens? S5 has this option, and I am asking because I find it very Cool

Back to cm11

I returned to cm 11 with f4k kernel 2.0.

Everything works great (oc, oc gpu, fast charge, bln etc). Not trying CM12(12.1) again.

After all the only improvement is ART (for s4 mini) and i didnt even notice any difference.

CM11 is stable and everything works as it should.
[Galaxy S 4 Mini Android Development] GNUDroid:
hey people stop spamming with wishes.

first of all: f4k is just one Person. we should be happy that at least one Person provides such a great cm kernel alternative. and further: if you want to help: first Google, if our device can do, provide technical facts and maybe patch sets from other devices. for example 2tap for wake: the s4 has no separate chip for that. for us if would mean that f4k could probably add this but the CPU would be always on. no sleep and 4h battery. :(

first of all: one person, second "thanks", third: speed and stability.

[Galaxy S 4 Mini Android Development] sasank360:
The official cm12.1 nightlies from the past 15-20 days have exhibited the same system ui crash with F4k 2.2.6 LP kernel.

Also frequent random reboots were observed. :( I took some logcats. But i misplaced those files. Maybe somewhere on PC.

Will post them soon.
[Galaxy S 4 Mini Android Development] Phenom2122:
Not sure if this info will be useful to anyone here but here are my observations when it comes to this rebooting story. I've noticed that there have also been a few people using F4k's latest CM build (0508) who mention random reboots. When I first installed it (first time coming from Android 4.4.4) and brought all my backed up apps with me I also got random reboots. Then a day later I reinstalled it clean and made sure to start again with all my apps too getting the latest versions and making sure there was no trace of any old data anywhere, not even on my sd card. I also stayed away from both Xposed and Performance Control (it crashes on my phone and cannot be trusted for now) and since then, I haven't had one single random reboot. My phone has been running perfectly for a while now, even battery life is awesome.

I may be wrong but I have a feeling that a lot of people's rebooting issues are because of old app data and because of apps that aren't completely compatible with lollipop yet.
[Galaxy S 4 Mini Android Development] Pangadaywalker:
I don't have any old data. What happens to me is the Multi Core Saver (something like that). Once I enable this reboots starts. I stop using it, and for 3 days in a ROM no single reboot.

I would say possibly this is the option you want to stay away. I am using AICP with F4K kernel and phone is fine after disabling that option (both S4 mini and S5).
[Galaxy S 4 Mini Android Development] csendre:
What do you mean by S5? You installed the S4 mini version of AICP with f4k kernel on an S5 and it actually works?

I disabled ambience display and still doesn't work. Also kernel adiutor app doesn't have any option to activate BLN, whereas in the past this was present.
[Galaxy S 4 Mini Android Development] tostep:
There is nothing to do with Kernel Adiutor if your have kernel with BLN support. Just install BLN control - Free or BLN control - Pro.

I have CM11 and BLN control - Free works fine. I only checked "Activate BLN":
[Galaxy S 4 Mini Android Development] llapao:
Maybe I wasn't clear enough.

My rom is CM12.1, using latest 2.3.0 kernel.

Kernel Adiutor has a BLN option where you can control _ANY_ kernel that has that functionality. In a previous kernel I was able to activate BLN via Kernel Adiutor; now I can't.

Also using BLN Notification I am experiencing issues, the soft buttons light once and then they turn off. No other notification app is on. Kernel was flashed via TWRP.

Thanks
[Galaxy S 4 Mini Android Development] Phenom2122:
I think that these are just things we have to deal with for now if we want to use Lollipop. There are most likely many things that need to be redone and that will take some time. A lot of people have been saying that BLN doesn't work. Take a look at the F4k's CM12 thread, in one of the recent replies a user has a possible solution but just remember that it's not perfect yet. We don't even have an official LP Rom for our devices.
[Galaxy S 4 Mini Android Development] Tirofog:
BLN does work for me, just no blinking.
[Galaxy S 4 Mini Android Development] GNUDroid:
