Porting to Samsung Galaxy Note 4 SM-N910P

libremax

@tigerpro Congrats, 3 Samsung Galaxy Note 4 models are now in UBports installer.

Can you precise what is functioning and what is not on those devices ?

tigerpro

@libremax at the time of this writing,

what works:
Audio
GPS
Status LED
Video Acceleration

what works with quirks:
BT (if disabled requires reboot to enable again)
SMS/MMS (seems to work overall, but sometimes there is no notifications for recieved SMS/MMS, Sometimes won't send SMS/MMS either)
Auto-Brightness (Sometimes has to be toggled off then on after a reboot)
Camera (GStreamer camera is needed for Camera to not crash the device, otherwise view finder shows then device crashes after a few seconds)

what doesn't work:
In Call Audio (Logs show it is working but it does not actually work, mic nor sound work)
S-Pen (detected by kernel, mir/unity does not handle styli input currently)
Sensors (they are detected, but no values are added)
Fingerprint Sensor (halium needs a repo for biometry services)

I think that's everything, if I missed anything I'm sure someone will chime in and ask, I also welcome anyone who'd like to try and help, to please do so.

@tigerpro Thanks for your answer
What about hotspot functionality ?

tigerpro

@libremax I only tried it once for a couple minutes, it turned the hotspot on, then off, and the device I connected was able to get to google, but I had the Samsung Quirks from Florian installed, and I didnt have it on for more than a couple minutes, so I would say it seems to work, but its not fully tested

Hi!
Congratulation for this port, I read all the work you have done to finish that it was very intresting.
I have this device but it have a hardware, stuck in boot loop if it's not plug to power supply. Anyway it still works so I want to install UT.
The devices is now on unofficial Lineage 16.0 (android 9), i used odin to install it and I have the TWRP recovery. Samsung drivers, ADB minimal and fastboot are installed on the PC Win10.
Do I have to go back to a stock to a stock rom to install it through the UBports Installer? I guees yes, which one is better?

Thanks.

@tchan if you already have twrp and a custom ROM installed, then your safe to install with the launcher, you dont need to revert software or anything. I will caution to make sure its a snapdragon variant as my port will not work on the exynos variant. I can say from experience, the bootloop issue your experiencing is a bad battery, I have 2 devices that had this issue till I replaced the battery. I would like to ask that you report back what happened if you do go ahead and try to install my port.

@tigerpro
Thanks for reply, I will retry, it didn't work yesterday.
When it reboot in fastboot mode after the first step, I saw "odin mode" on the first line code, is it a problème? Nothing after. Also I have to select the phone manually i the installer. Maybe I should remove the other phone driver before. I will check again if ADB reconize the phone. Cable is a USB 2.0
The phone is N910F it's a snapdragon normally. I thaught it was a battery problem but I change it 1 year ago...
If I manage to install UT I will check the battery.
Thanks!

Edit: after retry same problem, the phone reboot in fastboot through the installer but after I have this error : Error: heimdall:flash: Error: {"error":{"code":3221225781,"cmd":"C:\Users\<user name>\AppData\Local\Temp\1lbGW63w4cPeKpcts4AvNGVgPjG\resources\app.asar.unpacked\node_modules\android-tools-bin\dist\win32\x86\heimdall.exe flash --BOOT C:\Users<username>\AppData\Roaming\ubports\trlte\firmware\halium-unlocked-recovery_trlte.img --RECOVERY C:\Users\fanny\AppData\Roaming\ubports\trlte\firmware\halium-unlocked-recovery_trlte.img"}}
If it's not the right place to talk about this I'am on Teleport @tchan74.
I reported the issues on the Github UBports installer to.

tigerpro

@tchan that is an issue that I have not been able to resolve, I believe it may just be a limitation of the installer, when that error comes up click ignore if it is available and it should proceed as usual

@tigerpro
It's ok now ! ( my girlfriend have now a dual boot with ubuntu on her computeur and it was easier )
I write this from the phone you ported ! I hope you will find a solution to fix the audio call bug. I will check others fonctions.
It's very sad that you can't use your galaxy note 4 anymore cause the network support in US.
Thanks for this port.

so I found myself with about an hour of free time over the past couple days and decided to check into the wifi not re-connecting properly after a reboot, I suspect it is related to efs, I was able to verify it is mounted, but I have a suspicion its not mounted in the correct location, so that leads me to this question, is there a better way to force the correct location rather than putting a bind mount in init? Im not sure what else this will fix, or even if it will fix anything, but its a start since android mounts efs to /efs, and UT is mounting it to /android/efs, I suspect the stuff that is working is not fully working due to that.

Thanks for for your time.

@tigerpro related? https://forums.ubports.com/topic/6027/wifi-mac-adress/5

@doniks thats actually what made me think to check it, the difference is for my device efs is mounted and I can access it, but its mounted at /android/efs rather than /efs hence me asking if anyone knows if that matters, or how to fix it

flohack

@tigerpro The mounts in /android are made deliberately to not "collide" with the root file system. So you cannot change that. But the container should actually "see" those mounts at / ... if this is not the case, efs might need some treatment in the lxc container setup.

tigerpro

@flohack so if Im understanding correctly, the android side sees /android as /? if that is the case then how would I massage the lxc container to get the blobs to see the efs partition?
