Google made a lot of performance promises for Android 12 so it should run even better, but why stop to 12 if 13 can be done

The 18.1 is very impressive, runs great, some bugs there and here like sometimes the simcard stops being detected so I have to reboot, or GPS not working, but it's a great OS. Reminds me of stock ROM with all the features backed up of 18.1

For performance, the best thing to do is screen resolution + freezing apps + removing thermal throttle (the base thermal throttle of 18.1 is top notch but if you want to squeeze more performance from the SD805 at the expense of more heat, it's better to remove it)
[Galaxy Note 4 Android Development (Exynos)] Star Spangled Banner:
And the worst rom for our device is cyanogenmod 14 and lineage 15.

But it 's very good that our device is still alive and gets new custom roms.

And who knows ,what's wrong in custom roms that S-Pen does not work here ?

Is it impossible to make S-Pen work in custom roms with its stock-features?

From my own experience running 12 and 13 on MSM8974 (SD800) and a pretty modern budget phone (A20e with Exynos 7885), the animations are very sluggish compared to 11 and even with that disabled, is still slightly less faster than 11. And IMO the huge buttons look awful..

This rom isn't for the SD805 Note 4, it's for the Exynos 5433 variant.. Maybe you're on the wrong forum?
[Galaxy Note 4 Android Development (Exynos)] LegendOcta:
This is pretty offtopic but I'll post it anyway..

So, after 8 years of hard working, my Note 4 (SM-N916S) completely died yesterday.

I could enter TWRP but it was extremely sluggish, and booting android resulted in 0.5fps boot animation or a infinite reboot with weird graphic effects appearing on screen. Probably a cold solder joint. I tried to disassemble the phone but broke it even more and even dropped it in the process, now the display assembly is completely toast..

As the motherboard, the display, and the frame is all in a bad shape now I'm probably going to put my good ol' Note 4 in the drawer instead of repairing it. At least for now.

I just want to thank @ananjaser1211 for making this device usable for all these years. From RefinedNougat to LineageOS 18.1, the roms really made the phone worth using.

Hope the rest of the Note 4s stay strong.

That sucks to hear, thank you for being interested in my projects for many years now, while i wasn't able to deliver to the level of some other phones i maintain the note 4 remains my favorite platform dev and community wise due to people like yourself.

Good luck with your new device!

[Galaxy Note 4 Android Development (Exynos)] khamakelz:
Iam using N910C.. Been using this rom for some months now..... I love it ..thanks 🙏 to the developers...

Here is my issue

When ever i try to install custom ROMs starting from refinedNougat to this one... After booting into the new rom I usually dont have network connection so I use the EFS backup.

But the main issue is that I loose network connection when my data is on, mainly when the battery is around 62% and below

It will still show like a have data connection(LTE and network bars) but once I dial a number it will write "connection problem or invalid MME code" to regain connection i usually go back to the recovery mode and restore the backed up EFS from the stock ROM. When I stay without switching on the data the phone doesn't loose radio connection until the battery dies.

please help solve this problem coz its tiresome... everytime this happens i need to go back to the recovery mode 🤒 eeeh

have Tried many new batteries to no avail
[Galaxy Note 4 Android Development (Exynos)] Flo_dWild:
Good rom for daily use. Thanks
[Galaxy Note 4 Android Development (Exynos)] Flo_dWild:
I've experienced it. because the EFS information has changed. try going back to the stock ROM Marshmallow and flashing the appropriate CSC and have got root access. Download Phone Info ☆SAM☆ V.3.8.5, select secret code 2263, set Band Selection and Net Mode to Auto, and never turn off any Band. Don't forget to backup EFS for the next custom ROM. I hope this helps.

Hello, thank you for this ROM ananjaser1211

. First time to flash it in my Note 4 with extended battery. I'm using 18.1, I have a problem with banking apps. I used magisk, install modules from Shamiko and Safetynet. But it still doesn't work. Also Gboard doesn't show up so I installed other keyboard. Anyway, still a great ROM. I have a question, can we use kernelsu on our phone? is our phone arm64-v8a or arm-v8a? I'm really not sure. Again, thank you so much. First time to post here also :)
[Galaxy Note 4 Android Development (Exynos)] rpst_:
all roms on exynos note 4 are 32bit which should be armeabi-v7a. And for the safetynet google is currently doing some changes that break stuff. There was a new module that fixed it but it also got broken a few days ago. As for kernelsu it won't work as it requires either arm64-v8a or x86_64.
[Galaxy Note 4 Android Development (Exynos)] Buratei:
Just tried the latest test build

the good: no more system-wide lockups, seems rock stable

the bad:

1) system settings page still crashes when accessed from the quick menu (botched install, maybe?)

2) unable to sign into LGU network.

- the same USIM worked fine on the SM-N910K with this rom

- LGU network is visible when I tap automatic carrier discovery, but hangs forever when I select LGU from the list of discovered carriers

- manual APN editting is disabled (disconnected from the carrier)

Is there anyone facing GPS issue? Dont get right location.
[Galaxy Note 4 Android Development (Exynos)] rodolph66:
Hi everyone, before anything else I would like to greatly thank this community and all of its members and developers for the amazing work being done to keep many of our precious devices alive and kicking.

I was pretty shocked when I discovered that Note 4 has made it all the way to Android 11 (Lineage 18.1), and pretty excited to actually give it a try. I am no stranger to custom ROMs and installing them, but their development is a complete mystery to me.

To cut to the chase, I have upgraded my 6.0.1 N910C to 18.1, but alas the WiFi is not working. I revert back to STOCk and all is well. Again I install 18.1 and no WiFi.

There were a few posts regarding this issue but all seemed vague. Regardless non worked. I have some suspicion that rooting the device might solve the problem, but I would like to be sure first. There is nothing to suggest that rooting would fix the issue.

For reference, my stock ROM is: N910CXXS2DRL1_N910COJV2DRL1_N910CXXU1DPI1_HOME.tar

this might give a hint if any, and would appreciate and suggestions for attempting to fix this.

All the best.

Is any posibility to use "Y" otg cable (with charging) on this rom ? I was trying to connect device, but after connecting charger nothing happens
[Galaxy Note 4 Android Development (Exynos)] Flo_dWild:
If you have returned to Stock Rom, flash 4 Firmware files with Odin Mode and format the data. It seems there is nothing wrong with the radio & EFS configuration. If the provider there supports all the bands on your EFS N910C, it should work well. The device will automatically change from data mode to radio mode when you make a call. Try again to change the network to 2G or 3G to make calls. If you can't change the network mode manually, even automatically, maybe your problem lies with the hardware (bad RF IC, the flex cable of mainboard to the charging connector not connected properly (there is antenna path), corrosion, etc.). because every smartphone device (especially Samsung) uses an IC Switch to change networks manually and automatically. check again *#0011# make sure IMEI Certi: Pass, MIPI test: success, RX-TX OK network is registered. Force reboot with 3 button Power, Vol Up, Vol Down until restart and you got signal.
[Galaxy Note 4 Android Development (Exynos)] rodolph66:
follow up to my earlier post... (NO WiFi)

Things I tried...

_ All roms I could get my hands on, LO 16.0, 17.1, 18.1, Ressurection remix, (old/new), Havoc Os

_ Tried each ROM with/without root. Also, rooted the devices after the update (not that it was going to change anything!) - all with Magisk

_ Applied the workaround from : [BUG] Booting with NearbyShare enabled can cause WiFi to stop working

_ Did some settings change in Dev Mode based on some YouTube fix for WiFi (specific for SM note 4)

So far no luck with WiFI. When the device starts, after selecting the language, the serach for WiFi page just can't seem to detect any of the 7+ WiFi signals nearby including mine. Tried manually adding the WiFi but it simply does nothing. Even after continuing without WiFi, and using data instead, not at any point afterwards deos WiFi kick off or starts working.

After each failed attempt, I revert back to Stock (6.0.1). With everything working normally. I'm surprised the device still works properly after what I took it through.

Next I will follow the guide to filling a bug report on github and provide what logs required, on the hope that there u=is a simple fix for this. Thanks and regrads.

Attached are two device details info screen capture from settings in Stock Rom, for reference.

Thanks for this amazing rom, my device is n910c, I installed this rom and found 2 problems:

1- If the screen is locked for about a minute, it does not wake again, I did not find this problem in rom Refined Nougat N7FE

2- usually freezes during starting, I wiped the cache and dalvik but the problem was not resolved

Please help me solve these problems, thanks
[Galaxy Note 4 Android Development (Exynos)] Buratei:
Dropped my N916K by accident and ended up with a cracked screen :(

Been using my N910S instead, and still have some ligering issues.

I mostly keep my phone in deep sleep mode with all radio functions disabled, and 5v power input is supposed to wake the phone and do the wake sequence via tasker. It is behaving a bit erratic in that half of the times it won't see the incoming 5V input. It isn't tasker's fault or faulty charger/cable either, It simply doesn't see any power with multiple different charger/cable combinations. Only that that fixes this is an OS reboot, which lends me to believe it is something rom-related.

At this point, I am debating if I should just use 5V trigger for a full cold boot instead waking, seeing how now I am forced to manually wake the phone by an external button followed by a manual reboot.
[Galaxy Note 4 Android Development (Exynos)] juandante:
Interesting setup. Did you try to monitor system logs or/and use a monitoring app such as AIDA64 to see if it can detect the source?

Also I had a problem back in the day, when I was attempting to get a 24 hour battery life, if the phone was to much low in deep sleep mode it would be so slow that it would take time to detect events, could even be minutes
[Galaxy Note 4 Android Development (Exynos)] juandante:
Well, you are on the thread of the most stable recent ROM, lol. For me, this is to this date the best ROM for the Note 4, there are some problems (I had random Wifi bugs) but most of the time they can be fixed with a reboot.
[Galaxy Note 4 Android Development (Exynos)] Buratei:
The only sort of monitoring I have is ampere for (simulated) battery voltage.

I forgot to mention that this phone is a bit weird in that it likes higher voltage than what I am used to seeing on other similary modded devices. My nexus 7 used as car headunit, for instance, is happy with 3.9v-4.0v and never gave me any trouble with otg or wake/sleep detection. This galaxy note 4 like something much higher, like 4.7-4.8v. At 4.6v, it fails to complete the boot sequence and enters boot loop.

The buck converter initially had trouble supplying peak current during boot, so I've added some large caps and a diode to resolve that. Still, random 5v wake signal losses happen out of the blue.

For now, I am toying around with some software (tasker) workarounds.

To safeguard against false power loss

1) add a state variable which is set by the power resume task, and the power loss tasks monitors this variable for 7 sec to see if it gets reset

=> This should take out momentary lapses in usb cable/port connection

2) add a check for BT OBD2 adapter connection as an AND condition for initiating power loss task

=> I figured OBD2 connector should be connected to the phone as long as ACC power is being supplied to it, so it works as an effective indirect ACC detection

To safeguard against power reusme task being inadvertently rerun

1) add a check for nav app in foreground as an AND condition for initiating power reusme task

your problem is solve ? if not try this one.

1. Ur note 4 must latest stock rom & root, and Phone Info if u needed.

2. download and install Official SamFW Tool Latest

3. on SamFW Tool open tab samsung, ADB, connect ur note 4 with usb debugging activated, and click "Enable mobile data toggle", finish. restart and let check your mobile data connection 2G,3G, or 4G automatically change when u make voice call or MMI code.

this method work on N910H tre3gxx (with EFS & Radio Backup) and i change the AP to N910C for activating 4G Network.

mobile data wont change automatically when i try to make voice call, MMI, or turn on Wifi. sometimes the signal is null. i fix it use this method.

When iam using it with mobile data on it randomly looses network connection then starts a bootloop, another issue is when I restart the device it looses EFS it also bootloops, to solve this i go back to twrp and restore the stock rom's EFS
[Galaxy Note 4 Android Development (Exynos)] Flo_dWild:
if u go back to stock rom and problem not solved :

FIx DRK/dm-verity, Factory CSC and Serial Number

Hello, I have posted on various threads that i can fix DRK (Device root key), but after large demand in PM for the fix i have decided to make a tutorial, since i don't have much time to help everyone, this tutorial is only tested on SM-N910C...

xdaforums.com

go to mobile phone repair for hardware problem.
[Galaxy Note 4 Android Development (Exynos)] khamakelz:
Thanks for your help.

Indeed it has a drk error, i bypassed that by using the cf auto_root method. Another problem is about the EFS. The 1st time i flashed it, i did not make a backup of EFS so had problems with null IMEI,SN and i had no network, so I used cracked z3x and patched cert. the device was back to life but with a different IMEI and no SN.

So let me try that method will give feedback

Please help with banking app. Two days no clue.

I have a Note4 SM-N910H and needed to upgrade Android for a newer version because it is required by my bank application. So I flashed LineageOS 18.1, Gapps. Everything went perfectly well; in fact I love this "new phone".

The problem arises when trying to run HSBC bank application, wich detects that the OS has been altered. To find a fix I have read dozens of posts and youtubes, to find that this problem of the banking apps is a problem very common.

This is the last "setup" I managed to make:

- Reflashed LineageOs + Gapps again from scratch

- Installed Magisk Delta (kitsune-2 26.4) and rooted

- Within Magisk:

- Enabled Zygisk

- Enabled MagiskHide and hided Magisk

- On the Modules section, installed Shamiko 0.7.5 and SafetyNetFix 2.4.0

- Configured MagiskHide to hide Google Play Services/Store/HSBC Bank/ including all sub modules

- Cleared apps, rebooted many times

But HSBC bank app still does not run. ¿What I am doing wrong?

Two things about LineageOS:

- After any boot, LineageOS presents an alert that SELinux is Disabled

- Also saying that Encryption is Disabled

Thank you very much for any help!

Hi all, updating the Note 4 Rom - this post - is missing a step by step guide for all or any new comers. The SourceForge mirrors, and Wiki provide separate instructions for each part but does not provide any guide on how all parts are connected and where to start. I have noticed a few confused users and they reflect the same feelings I had when I first visited this post. In other similar posts there is always a brief step-by-step guide to accomplish the installation of the ROM. It would be much appreciated if such brief is provided here. Thanks again for all your hard work.
[Galaxy Note 4 Android Development (Exynos)] rodolph66:
As for the issue with WiFi, I have not been able to find a solution. The behavior is somewhat odd. In some cases when the wifi does work, the data connectivity fails. To get the data working I have to turn off wifi, restart the mobile. Then if data is working Wifi simply refuses to connect. In other words either Wifi or data can work at any point and shifting from one to the other requires restarting the mobile plus changing other network settings... (too much hassle).

I see that now one other person is having similar issues. Perhaps this matter can be looked into at some point.

Again, thanks a lot, and best regards
