[Galaxy Note 4 Original Android Development] just1nsama:
Running it on mine since yesterday, i have N910W8 running on stock MM and this the first custom kernel i am trying on this device. It is some what stable as long as i don't mess with freqs and the ondemand governor as it reboots my device on the first scroll up or down. That being said it might just be the mpdecision acting up when i'm playing with freqs, i leave it enabled because it is the main feature i am looking for as it really helps with battery life ... but i would really like to be able to play with min/max freqs and use ondemand governor while not having the stability issue.

Not inquiring, just reporting behavior i have noticed playing around with this kernel with the N910W8 variant.

Big ups on the work done, i know compiling stable kernels is no picnic.

[Galaxy Note 4 Original Android Development] audiomarko:
Hello, RAM121, in the Spezials in your Kernel stands fixed for F2FS. Ich if a ROM (MickyROM 3. 1 N915FY) on F2FS has formatted and your Kernel geflasht. Rest kind in the Recovery. It functions only of the MickyKernel. I would use your Kernel with pleasure in F2FS file system because man more put can (experiment). Can you realise this? Furthermore great work
[Galaxy Note 4 Original Android Development] blackhawk_LA:
I don't understand. You should try to explain it better. Do you mean you were able to boot your rom on f2fs? I think it was not working.

In case you think it's working for you, have you checked it? Using system panel you can see if it's working or you are using ext4fs
[Galaxy Note 4 Original Android Development] audiomarko:
Google has been translating. See new translation
[Galaxy Note 4 Original Android Development] blackhawk_LA:
More or less I understand. But I haven't seen any ROM/kernel for N910 that truly supports f2fs. It seems very hard to implement, so I think that it's not going to be a priority.

Although it would be great since performance is MUCH better with this filesystem.
[Galaxy Note 4 Original Android Development] ruicc:
I had the same problem, it was showing: "CTS profile mismatch". This is what i've done:

- deleted busybox from system/xbin

- enable magisk busybox and magisk hide on settings.

Reboot and passed safetynet
[Galaxy Note 4 Original Android Development] Ram121:
F2FS support is present in the kernel, just a minor modification is required in ramdisk, but that modification breaks magisk.

Last time it was tried with that modification, cache and data was F2FS and System was ext4.

Much trial was not taken. Personally I have not taken trial. Also it need modification in updater script of rom also

Best battery settings on RC2 for N910F....???

I've used ram kernel for a few weeks now.

Currently running the latest RC2.

Only problem is battery drain with the device if I just use -70 undervolting.

+ Changing GPU governor to powersave (phone perfectly stable)

If I change CPU governor to zzmove and try profile 4 (zzbat) or 11 (zzrelax) the phone frequently enters deep sleep and shuts down randomly every 30 minutes or so. So I've left the governor as interactive (default).

I tried to enable Lspeed as well and while that seemed to work the Wakelock blockers are showing as on in Lspeed and off in Kernel Auditor.

I know someone else reported this on an older version but can someone please confirm if the same is true on this version of the kernel as well.

Please also advise if there is a work around.

I'm using hardrock83 update7 ROM.
[Galaxy Note 4 Original Android Development] Tesla:
Hi.

1. When you use zzmoove, will it shut down even if you don't undervolt? What about other zzmoove profiles?

2. Do you have logs? (IMPORTANT)

3. In Lspeed, are "on" not actually off in that app? Read carefully the deskription.

4. In general it's a bad thing to use two apps that interfere with the kernel. Maybe try without KA and only use Lspeed or the opposite?

For testing purpose.
[Galaxy Note 4 Original Android Development] Ram121:
See screenshot (page 38 of thread)

Benefits- Improves stability, battery and performance

Yes its true for this version also

Above post is also true, using two apps/mods simulteniously will create problem

[Galaxy Note 4 Original Android Development] u81:
Thanks for the prompt response.

I haven't actually tried zzmove without undervolting.

I do have better battery stats installed so I'll try to get logcat.

The reason for trying Lspeed is that I don't know how to tune CPU governors manually in kernel auditor + zzmove sleep of death etc.

This is my wife's business phone so trying to experiment with various scenarios is a bit difficult, but I shall try.

When using zzmove using profile 4 or 11 , I've experienced sleep of death on both.

Do you expect the battery savings to be higher without undervolting and trying zzmove profiles on their own.

Can't use Lspeed on its own as doesn't support undervolting.

Again, many thanks for responding so quickly.
[Galaxy Note 4 Original Android Development] Tesla:
Hi m8.

Do you have any news or log?

To be honest i don't know what it will do to battery savings.

Every phone is different that's for sure. And use vary. So all we can do is follow what have worked for others or try our own settings.

How about you try with just Lspeed? Don't bother with other apps for now. Clear data and uninstall them/it.

//Tesla.
[Galaxy Note 4 Original Android Development] u81:
Mate, many thanks for asking.

What I've done since our last contact is as follows:

1- wipe data for kernel auditor

2- wipe data for L speed

3- flash the emergency settings cleanup zip that you posted earlier in the thread

4- rebooted the system

5- revoked SU permission for L speed

6- using kernel auditor - changed CPU governor to zzmove & profile 4(zzbat)

7- CPU hot plug - use intelliplug

8- changed GPU governor to powersave

9- battery - usb fast charge

I didn't get any sleep of death as yet but the phone seems to miss all of WhatsApp calls but not all Viber calls.

Battery drain seems lesser in comparison to yesterday.

About two hours ago I started undervolting the CPU at -60 in addition to the above config.

I'll post update again.

Thanks for asking.

And of course a big thanks to Ram for giving a new lease of life to our very fast/ capable hardware let down by Samsung's deliberate software meddling.

Samsung galaxy note 4 N910F

Hardrock83 update 7 ROM

Ramkernel RC2
[Galaxy Note 4 Original Android Development] Caalex:
I've been having give battery trouble with RC2 I can't get it to last me the day... waiting for your update and I will try the same set up :o

Does changing CPU voltage help with battery consumption or just crashing?
[Galaxy Note 4 Original Android Development] blackhawk_LA:
Reducing voltage always save a little bit of battery (don't expect half an hour more of screen on time) and also reduces overheating (for me this is the more important reason to use it).

But undervolting leads to instability when reaching a limit. So try step by step, and don't tick "set in boot" until you find it is stable. From what I've read, most users can undervolt from 50 to 100 mV. I encounter a few reboots when going more than 80mV
[Galaxy Note 4 Original Android Development] u81:
With -60 mv undervolting, I didn't experience any reboots or sleep of death, but the phone couldn't be answered when ringing on a good few occasions hence I've just changed the undervolting values to -50mv.

Let's see how it goes.

I fully agree that the device runs a lot cooler with undervolting, so there's bound to be a battery saving and I think it is noticeably better than the phone was a few weeks ago when I was on stock ROM.

Hardrock83's update 7 ROM made a great deal of difference in the fluidity of the ROM and I think Ram kernel RC 2 is benefiting from that too.

I would still like to observe for a bit longer before I can quantify the benefits but I'm definitely feeling a lot happier with the current configuration.
[Galaxy Note 4 Original Android Development] u81:
[MENTION=5229173]Ram121[/MENTION] [MENTION=4901223]Tesla[/MENTION]

With-50mv undervolting the idle drain is at 1.3% per hour.

Not ideal but still a lot better than before.

But I've only been using the phone for about 10 minutes and the drain has jumped to 2% per hour already.

http://www.samsung.com/us/support/answer/ANS00033839/

I can't see how that could be kernel related. But then again,, the mysteries of android are many ;)

Have you asked the Dev of your ROM?

It's working with all other kernels you can use?
[Galaxy Note 4 Original Android Development] rob_z11:
Yep. I have been keep hearing various answers over the years. Some say it is kernel related if they have implemented support. I had run dual boot for a long time, and had MMC error. I ended up swapping system board, and I am now afraid to stress my phone.

Sticking with ported rom or stock, and try not to run aosp rom such as lineage or others.
