Kernel Adaptation

CM 12.1 is snappy but the warming up issue and overheat issue while playing light games.

I was wondering if anyone had a solution to this. I know its a Kernel Problem.

The stock rom for the n910p is good in battery life, fast charge, thermal fixes and is all because of the stock rom kernel from samsung. I tried flashing it in CM12.1 and it stuck at boot. Is there away to import the Samsung stock kernel from the note 4 in cm12.1?

If you made a nandroid backup of your stock rom? try recovering your modem and efs. Should work. It worked for me at least
[Sprint  Galaxy Note 4 Original Android Development] chris378:
It says my phone is not rooted..is this ROM pre rooted? If not how can I get this ROM rooted? Sorry for the noon question
[Sprint  Galaxy Note 4 Original Android Development] G U C C I:
Its in the developer settings I believe
[Sprint  Galaxy Note 4 Original Android Development] chris378:
Gotcha I'll look into that, other issue is that my phone will not connect to LTE, I have done the *#*#4636#*#* fix but I'll out it on CDMA auto PRL, I'll wait 30 secondd and get 3G but then when I switch to LTE/CDMA auto PRL I get nothing and a ! next to the signal strength Instead of 3G or 4G

System Settings - About Phone

Tap "Build number" 7 times

Back out to system settings and you'll see "Developer Options".

Tap that.

9 lines down you'll see "root access".

Tap that and select "apps only".

Can anyone share average screen on times running Cm12.1 and stock battery please?

My note 2 typically gets 6-7 hrs screen on time - just wanted to see how the note 4 compares...
[Sprint  Galaxy Note 4 Original Android Development] Psytra:
I am a pretty light user but I have 1h53m screen on time with 70% battery to go. My browser uses more power than the screen.

Edit:

50% battery usage now. 2h28m screen on time which is 9%. Browser is 11% with 1h14m CPU total.

Edit2:

Battery at 31% with 3h51m screen on time which is 13%. Browser is 19%.

If I didn't use the browser as much it would easily last 6-7 hours of screen on time. Hope this helps.
[Sprint  Galaxy Note 4 Original Android Development] XAlexander_AlexanderX:
Running smooth over here :)
[Sprint  Galaxy Note 4 Original Android Development] Drayspencer:
After flashing the OG5 .tar and odin TWRP 2.8.7 I flashed SuperSU 2.49. But once I flashed CM 12.1 and booted the system Root Checker said I was "not" rooted. I simply went back into TWRP and flashed the 2.49 zip again and all has been well since. Hope this helps.

[Sprint  Galaxy Note 4 Original Android Development] chris378:
Yes I got the rooted issue resolved by developer options : ) Thanks but still having issues with getting 4G, I have followed all instructions on this forum and I have also looked around for other fixes and still no luck : / is there a .zip file I can flash to fix the issue?

---------- Post added at 10:47 AM ---------- Previous post was at 10:35 AM ----------

I also noticed that I had my work emails forwarded to myphonenumber@messaging.sprintpcs.com so that I would receive them as SMS..is this option not available with this ROM? If so what should I do to start receiving them again
[Sprint  Galaxy Note 4 Original Android Development] BlackSheepA1:
I been using trltespr cm12.1 and the only issue I've stumbled was the heating issue near the back camera and the gaming peformance heats my phone excessively and battery drains very quickly. Is there a possible way to port or install the BOF5 stock kernel to CM12.1? It would be the most stable ROM for the Sprint Note 4. There's got to be a way to port the BOF5 Kernel to CM12.1! Someone please get back to me! :)
[Sprint  Galaxy Note 4 Original Android Development] G U C C I:
Nope. Stock is based on touchwiz which is all proprietary
[Sprint  Galaxy Note 4 Original Android Development] BlackSheepA1:
You've got a solid point. I can't argue with that. I been trying to dissect the stock kernel to see what makes it very stable and had no luck. Hopefully I keep doing research and fingers crossed I stumble into a kernel most similar to that of the Touchwiz Kernel. Thank you iTzFeRReTTI!
[Sprint  Galaxy Note 4 Original Android Development] G U C C I:
We're stuck using open source drivers and such which will never be as good as Samsung's proprietary drivers
[Sprint  Galaxy Note 4 Original Android Development] BlackSheepA1:
;) True we're stuck with open source but there is always a way! Recently tx_dbs_tx figured out how to enable root in N910P COG5. Which was impossible at first. Not all bad :) Someone somewhere is trying to achieve the impossible possible! we just have to be patient (sometimes) lol
[Sprint  Galaxy Note 4 Original Android Development] chris378:
I have found a way to fix all issues I have come across but I cannot find a way to get 4G working : ( 3G works but cuts in and out, when I go to APN settings then is none, it say "APN settings not available for user"...does anyone have a fix for this issue? I've spent days researching and trying fixes, none of them work : /
[Sprint  Galaxy Note 4 Original Android Development] chris378:
Boom! I figured out a fix for No APNs and No 4G..I'm not recommending this just saying it worked for me.

1. Download this ROM http://xdaforums.com/showthread.php?t=3179078

2. Back up with Titanium Back up (User Appd only)

3. Back up SMS

4. Went to TWRP and did a full wipe 3 times.

5. Installed the ROM and let it fully load up.

6. Went through the startup process but didn't setup anything.

7. Did a PRL and Profile update.

8. Went back to TWRP and did a full wipe again 3 times and reinstalled CM and GAPPS.

Now I have all APNs and 4G works : )

I apologize up front if my instructions are amateur lol I've done this for years but by far from a master at any of this lol just a lot of fun for me
[Sprint  Galaxy Note 4 Original Android Development] nivron:
Do not flash the 0826 nightly if you use Chrome. There was a bad upstream merge that makes it nonfunctional. I do not know if it affects other browsers at this time.
[Sprint  Galaxy Note 4 Original Android Development] monkey3ddd:
Chrome is borked, but the stock browser works.

Hopefully fixed for tomorrow.
[Sprint  Galaxy Note 4 Original Android Development] nivron:
I've done an unofficial build which has the fix in it. Tomorrow's nightly should be fine as well.
[Sprint  Galaxy Note 4 Original Android Development] monkey3ddd:
Did you post the unofficial build and I missed it?

Thx
[Sprint  Galaxy Note 4 Original Android Development] nivron:
No, I only built it for myself -- testing some other stuff too, not really usable as a daily build.
[Sprint  Galaxy Note 4 Original Android Development] gimmezell:
Hello, I just installed the latest nightly today. What nightly can I dirty flash to get Chrome working?
[Sprint  Galaxy Note 4 Original Android Development] nivron:
You can flash the 0827 nightly from here or update via CMUpdater.
[Sprint  Galaxy Note 4 Original Android Development] Nrod0784:
So I did the fixes outlined for GPS and sms and data... However I still cannot send mms. Any help would be appreciated. Thanks!
[Sprint  Galaxy Note 4 Original Android Development] mediawiz:
Ever since 8/25, every nightly build for Sprint Note 4 has had the (often recurring) issue that the "Global" setting in the "Preferred Network" dialog is missing. :( This seems to happen a lot with nightly builds for Sprint GN4.
[Sprint  Galaxy Note 4 Original Android Development] mikexmayhem:
Anyone figure out how to get network settings go to stick yet without having to access *#*#4636#*#* menu?
[Sprint  Galaxy Note 4 Original Android Development] G U C C I:

[Sprint  Galaxy Note 4 Original Android Development] logikzzz:
Any kernel that supports viper4android out there? I've used a couple different ones and they lead to lockups occasionally.
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
I use LTE switcher and just make sure I am on CMDA before booting/rebooting and toggle LTE after boot/reboot. I don't think there is an official fix for this specific CM based issue. I know its a hit or miss with different phones, for example mine ALWAYS has to be forced to CDMA to send texts on boot/reboot whereas others seem to work fine.

To me though, its a small price to pay to have a smooth, stable AOSP and not be forced to use the horribly bloated stock TW OS. I gladly use CM with setting to CDMA on every boot.
[Sprint  Galaxy Note 4 Original Android Development] Patch7:
This is actually the first version of cm12 that works for me without having to manually force and switches to CDMA mode. It works after a fresh install and has been working flawlessly so far
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
Thats interesting, what nightly version are you using specifically? I would like to try it.
[Sprint  Galaxy Note 4 Original Android Development] Patch7:
The latest nightly. Sept 15th. It defaults to cdma/gsm/lte and works good as is.
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
Really? You can send texts while on GSM? I never could but will try it right now, thanks! I will let you know in a few minutes...
[Sprint  Galaxy Note 4 Original Android Development] mikexmayhem:
How's it go groovy?
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
To be honest, it seems to be working but before I confirm 100% I'm doing alot of normal use and rebooting many times.

So far no issues other than a slight data loss but not sure exactly what caused that yet.
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
Not sure why admin added this note as it's not relevant at all but that's fine.

Any way GSM/CDMA/LTE seems to be the working across reboots/updates so this is great. I'll keep testing and report anything if I find any issues.
[Sprint  Galaxy Note 4 Original Android Development] ffolkes:
Does anyone know how to get the barometer sensor working? I've poked around in the kernel, and can control it, but I don't know where Android is looking to read that data from.
[Sprint  Galaxy Note 4 Original Android Development] D_Smuv_:
How can I make the volume louder?
[Sprint  Galaxy Note 4 Original Android Development] mikexmayhem:
Good to hear. I'm testing it myself. So far with no luck. I'll keep messing with it
[Sprint  Galaxy Note 4 Original Android Development] Patch7:
It worked for me in the 9-15 nightly build. However after installing the newer nightly build it doesn't work anymore. I need to manually change to CDMA and then lte/cdma to get it working. I relflashed the 9-15 build and it works again without any manual change or setting.
[Sprint  Galaxy Note 4 Original Android Development] mikexmayhem:
I can't even get data on the 915 build. I may try some other ones though
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
It's working flawlessly for me through reboot/shutdown/ETC!!!!
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
Edited to add airplane toggle
[Sprint  Galaxy Note 4 Original Android Development] wrchad23:
on the 9.18 and 9.21 nightly I have SMS issues after reboot. I'll try the airplane mode trick.

*edit* airplane trick doesn't work. Only thing that works is changing to CDMA (auto) then back to LTE/CDMA (auto).

I also notice after I reboot sometimes it will be on LTE/GSM (auto) which gets me no signal. The toggle above gets it working again. Sometimes when I reboot it's on LTE/GSM/CDMA (auto).

I noticed if I switched to CDMA and back to either LTE/CDMA (auto) or LTE/GSM/CDMA (auto) it will work okay. But everytime after reboot it requires the manual toggle.

AudioFX Screen Blank

My AudioFX screen is blank - cant see any audio settings, nor adjust anything within it. Only thing i can adjust is reverb and randomly click where EQ's should be and it will adjust the preset to custom. Doesnt seem to make any sound adjustment tho. Is there another app, or a way to get this working? Was installed clean install.
[Sprint  Galaxy Note 4 Original Android Development] wrchad23:
Mine has the same issue.
[Sprint  Galaxy Note 4 Original Android Development] m4xwellmurd3r:
Is there any way to manually set the LTE band priority? I just realized my phone will ONLY grab band 25, even though I'm in a band 41 area (sprint spark) my gf's phone can pick up on band 41, but mine just goes to band 25. I'm thinking of flashing an odin stock rom to update my firmware and stuff and seeing if I can somehow get band 41 working.
[Sprint  Galaxy Note 4 Original Android Development] G U C C I:
Anyone getting notification issues and crashing apps on the 9/23 nightly? I did and then reflashed 9/22 and it was fine
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
Unfortunately for me, I have discovered while on GSM/CDMA/LTE I am unable to send MMs pictures. It happens on all CM/AOSP ROMs. The error toast notification is no APNs selected. If i change back to CMDA/LTE the APNs load and MMS pics send with no issues. So I will be testing manually adding APNs to the GSM/CDMA/LTE network and see if it works but as of now I cannot leave on GLOBAL (GSM) or no pics will send.
[Sprint  Galaxy Note 4 Original Android Development] altimuh:
Just got my note 4. Other than this issue, how solid is Cm12.1 for the note 4? (I had it on my note 2 and it was my daily driver - there were a few quirks, but for the most part it was great)

The issue with the mms and global conflict - do you need to select cdma/lte on each reboot, or does it stick?

How much screen on time are you getting with Cm12.1?

Does quick charge work?

Any phone call issues? (on the note 2, callers would hear their own voice as an echo.... Slightly unprofessional for business calls... Lol)

Thanks in advance!
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
VERY solid, no issues or FC's. i get very good time with my phone, it will last all day if I just leave it idle for phone/texts but if I play a game, it will sap it in about 2 hours.

No call issues, clear as a bell. The Note 4 in my opinion has been the best in the series so far (other than only having one modem in the device whereas my Note 2 had two so I wouldnt lose data when i received a call).

Setting to /CDMA does not stick for me but others have said they dont have to but I always do.
[Sprint  Galaxy Note 4 Original Android Development] nimaim:
CM runs awesome, only problem is u lose some nice features of the phone unless u do some crazy workarounds: native spen, better cam, better data speeds, fingerprint reader, and any TW features like wifi calling. With CM, this phone is essentially a nexus 6 which is saying a lot.
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
True but that's with all devices going from a TW ROM to AOSPs. The speed and untouched OS without the bloat is more than enough a trade off for me to be happy without the nifty feature we lose.
[Sprint  Galaxy Note 4 Original Android Development] sekinger:
I did a clean install of Oct 3rd build and have noticed the phone is running warm and battery life is way down. Anyone else seeing anything odd from that build? I think I'll wipe and install today's build just in case something small went wrong during my recent install.
[Sprint  Galaxy Note 4 Original Android Development] pstarkey001:
May have to give it time to settle if you haven't already. Usually takes a few days.
[Sprint  Galaxy Note 4 Original Android Development] sekinger:
You may be right but I've not had any other flash get so warm or run the battery down so quickly. I didn't have the patience to watch the battery drain in 5 hours. When plugged into my laptop, it was draining faster that it could charge.

I wiped and installed Oct 5 but could not get registered on Sprint's network. I went back to my previous backup and all is running well. After a day or two I'll try again.
[Sprint  Galaxy Note 4 Original Android Development] pstarkey001:
As far as battery drain that is largely due to being plugged into laptop because it doesn't put out enough power to keep up with charge. Try using charger that came with your phone.
[Sprint  Galaxy Note 4 Original Android Development] sekinger:
I understand the differences. I've been around the CM community since the original motorola droid and cm6/7.

My laptop does put out enough power to charge my phone. With that specific build my phone ran warm and the battery drained in a quarter of it's usual time. I restored back to a 9/26 build and all is good.

I was simply trying to tell others that I had an issue with that build and the next one too. One caused the phone to run warm, the other build failed to join the sprint network.
[Sprint  Galaxy Note 4 Original Android Development] Axiom119:
Flashed the 10/8 nightly. I can no longer send SMS. I can still receive though. Google Partners, whatever that is. Force closes.
[Sprint  Galaxy Note 4 Original Android Development] D_Smuv_:
Anyone know when there will be a android 6.0 marshmallow rom for our note 4?
[Sprint  Galaxy Note 4 Original Android Development] dtr145r:
I couldn't send sms on 10/10 either...
[Sprint  Galaxy Note 4 Original Android Development] dtr145r:
Anyone have luck with sending sms on the newer build yet?
[Sprint  Galaxy Note 4 Original Android Development] monson987:
I can send/receive SMS/MMS on 10/10 nightly. I did a thorough wipe before installing. Camera is a little finicky at times, especially when an app like "MD Scan" tries to access it (camera scanning to PDF). Sometimes my touchscreen doesn't respond (usually when the phone is in deep thought processing something), but resetting fixes that. Also discovered my Google authenticator app doesn't work for whatever weird reason (Dropbox doesn't like the codes it gives me), but the solution to that was switching to SMS authentication. Other than that, runs smooth, GPS and all. Battery life is amazing!
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
I would give it a while for the code to be released
[Sprint  Galaxy Note 4 Original Android Development] johnp1991:
This rom was working good until i lost data and the phone says emergency calls only. Help anyone? I want this rom as my daily driver bummer
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
Use the testing mode and set back to CDMA then turn off the radio and back on
[Sprint  Galaxy Note 4 Original Android Development] johnp1991:

What you mean by testing mode?
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
Oh sorry, open the dialer and type *#*#4636#*#* and the test menu will open, then follow the steps
[Sprint  Galaxy Note 4 Original Android Development] johnp1991:

[Sprint  Galaxy Note 4 Original Android Development] mikexmayhem:
Keep reading this thread. This issue has been explained many many times
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
and did you set to /CDMA like the advice i offered after opening the testing menu?
[Sprint  Galaxy Note 4 Original Android Development] johnp1991:
Got it to work thx for helping now just one problem. My gmail wont send emails.
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
welcome, go into settings, apps, all apps, find gmail and clear cache and clear data, let it re-download your email and retry, it should work now. there's a bug with Gmail if you flash and or use a nandroid with emails not sending
[Sprint  Galaxy Note 4 Original Android Development] johnp1991:
Thank you you have helped so much. Rom seems usable now.
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
Welcome, remember to do that if you restore a Nandroid OR install a new flavor AOSP and GMAIL doesn't send. Its a pretty much sure fire way to fix it.
[Sprint  Galaxy Note 4 Original Android Development] youssef7:
Okay I have a zerolemon battery for the note 4 10,000 mah. I love this rom cant wait for finger print or more features. BUT the battery life!? Its horrible. My note 4 with the zero lemon usually last 2 days+ with cm its one full day. What gives? Its ok but needs to be pointed out and I hope the next couple nightlies can help the battery! because I really don't want to leave this rom. Thank you for all the hard work!
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
Does the zerolemon battery really add more life to the charge or is it hype?

And don't expect any better life with AOSP out of the box without tweaking it plenty on your own. It's not the nightlies it's the way the cores are used
[Sprint  Galaxy Note 4 Original Android Development] youssef7:
Yea your regular battery is 3000 a zero lemon for the note 4 is 10000. Also I have tried cm remix and didn't really like it because it was way to buggy. So your saying cm12.1 is just bad on battery over all? Because I read reports of people saying they see no difference which some say its really bad
[Sprint  Galaxy Note 4 Original Android Development] ffolkes:
With the latest Plasma kernel (which I'll be releasing within a day or two) using stock settings, I get fantastic battery life using the 12.1 nightlies. So far my record is 2 days 1 hour (49h) on standby, with 4 hours screen-on (not just idle screen on, actual use: messenger, texting, reddit, instagram, etc) and using whatever brightness was comfortable at any given time. I use a stock battery, so I'd imagine a zerolemon would be ~x3.
[Sprint  Galaxy Note 4 Original Android Development] youssef7:
Wow okay yea I never got into kernals. I see the admin linked us to a different thread. But I hope what we are talking about is fine here. Okay so whats the kernal that I should flash right now? And how does it work just to recovery flash kernal and rebot? Thank you

Does this break or make the nightlies anymore unstable? Whats the cons of not using the kernal that comes with cm12.1
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
[MENTION=349360]ffolkes[/MENTION] do we have any kernels for sprint Note 4 AOSP? I only found one's for TW but loved the kernel on my note 2.
[Sprint  Galaxy Note 4 Original Android Development] youssef7:
Okay I have a very important question for the developer or anybody that has info on this. Is fast charge auto turned on in cm12.1? I need it to be off to charge my zero lemon. I noticed my zero lemon wasn't charged even when it says 100% so I was wondering is there anyway I can calibrate it any better on cm12.1? Thank you

One more question why no apps 2 sd?
[Sprint  Galaxy Note 4 Original Android Development] youssef7:
ughh i messed with the privacy guard and now I cant send text msg. I HATE THIS ABOUT THIS ROM. You mess with o much and sending texts stops working and the only way to fix it for is to load a ****sung rom and then flash back to my lovely cm12.1 lol ughhh im just pissed because im at work and my phone cant be doing this kind of crap while at work.
[Sprint  Galaxy Note 4 Original Android Development] GROOVYJOSHCLARK:
I have NEVER heard of that issue ever. Are you sure you just dont need to set to /CDMA in the testing menu? If you are going back to TW you are most likely just setting your network to /CDMA. What happens when you try to send and are you 110% sure you are on /CDMA when sending texts?
[Sprint  Galaxy Note 4 Original Android Development] youssef7:
Yea I have to go tw then back to cm12 then do the whole registering network and stuff while im connected to wifi then I can send msgs and go on lte with no problem. Even after reboot idont have to do anything just works normaly if you register the network but u can only do it on wifi forsome odd ass reason. its really annoying because my phone is now ****ed while im at work and I just wana throw my phone and set it on fire lmao jk
