This LOS doesn't work with Snapdragon 820 SoC which is used in G930U variants of the S7. I'm not even sure if your bootloader can be unlocked.
[ROM][STABLE][Signature Spoofing/MicroG support] LineageOS 18.1 for S7 Exynos

yeah, the bootloader can't be unlocked for s7 snapdragon
Sorry buddy, your device is NOT eligible for intensive modifications, as your hardware is not the same as the international S7.
Check out:
Click here.
If you managed to flash Snapdragon TWRP, you may not be able to flash this ROM, and I highly recommend not to even try, as your device WILL literally die.
Check S7 Snapdragon section for ROMs.
When I set the brightness to the maximum, after locking the screen, it changes to zero and the brightness bar remains at the same level (100%).
The function keys (those next to Home button) vibrate when the screen is locked.
only regret is not having the Samsung stock camera doing its dirty job well
@Ivan_Meler and everybody here:
Do the SamsungHealth and related apps work with this great LOS release? As I own a Samsung smartwatch, I would like to still have it synced with my S7.
Which camera would you recommend? Or which modifications (if there are such) for the camera app that comes with LOS 18.1?
It is a pity that the vendors' stock camera apps cannot be integrated in LOS (or other custom ROMS, if I see it correctly). Is there anything that could be done about this for LOS 18.1 on the S7 exynos (herolte)?
Anyway, thanks a lot @Ivan_Meler for the great work!

but it's a bummer that even following the steps to the letter, it crashes me .

Hi dear, may I know how do you update your baseband while sticking to lineage os? I did some research on it but so far I can't get a clear answer. Do I need to go back to stock rom to update my good old baseband via odin? Or there is other trick get job done faster?
You can update the baseband with Odin, no need to go back to stock rom.
You can Download Firmware from sammobile and select your Country then Flash BL and CP in Odin only
sammobile.com/samsung/galaxy-s7/firmware/SM-G930F
AP: is your system partition with recovery and stuff.
BL: your bootloader
CP: your modem
CSC: this is what features you get in some countries or carriers like Wi-Fi Calling.
CSC and AP is only for samsung stock rom
If you flash CSC will wipe your data.
If you flash CSC_HOME will not wipe your data.

Great to hear! So to update the baseband will only need to flash latest BL, CP and CSC_HOME to keep recent data will do.
Some applications (likes LinkedIn or Spotify modded) do not work with wifi, it results is offline, but as soon as switch in mobile data, works
no CSC and AP is only for samsung stock rom
you should only flash AP and BL with odin

Anyway I already flashed BL, CP and CSC_HOME , it works great now
Thanks for you kindly reply.
Sometimes the microphone doesn't work. Restarting doesn't help, only wipe dalvik/cache helps.
The thread below seems to indicate that it is possible to get Volte/wi-fi calling working on the SM-G930FD version of galaxy S7 (dual sim).
[EOL][ROM][STABLE][O][8.0][ERG2][31.08.18][SM-G935F/FD/K/L/S/W8] SuperMan-Rom V3.0.1
What does this rom feature? Well it is based off from the latest G935FXXU2ERG2 (Oreo) base, with all apps removed that can be downloaded threw the playstore, so it is debloated as well. I really like touchwiz as it is on 8.0, that's why I only...
Is that only possible with the stock ROM and not lineage OS 18.1 ?
I am interested in wi-fi calling due to poor cellular signal on T-mobile network if possible.
I found something that doesn't work. It is a little know/obscure feature of our devices unless you are a running or cycling enthousiast. And that is ANT+.
I recently bought a home trainer which is compatible with Zwift (kind of a serious video game where you can cycle in a virtual world). I can link my hometrainer via bluetooth and it works perfectly. However I would like to pair my Garmin forerunner 235 to have a heartrate monitor. Unfortunitly that watch only supports ANT+ for heartrate transmission. I used it succesfully with strava on the S7 in the past, but Zwift can't find the device.
So done some digging:
- reinstalled ANT Radio Service
- Anttester says built in ANT detected: NO
I happen to have my wife's old S7 with a broken screen with stock rom on it and it works there:
CM18.1:
Stock S7:
It might be just a permission issue. However ANT Radio Service never asks for permissions and I don't know how to give an app or service persmissions it is not asking for without root acces.

As always big thanks to everyone who donated as that helped offset the build server cost and keep the project alive with yet another android version
17.1 builds will be updated in a few days
Enjoy new build and stay safe2For the issues with reboots and corruption with SD cards formatted with the exFAT filesystem that have been discussed recently, those would be caused by an update to the sdfat driver, used for exFAT filesystems, in the kernel causing kernel panics: https://github.com/LineageOS/androi...mmit/ddba1674688968d672c5529068b8690ee5e79da7
Over on another device, the Samsung Galaxy Tab A 10.1" (2016), which also uses a 3.18 kernel, I found that the updated version of the sdfat driver (2.4.5) caused kernel panics when writing heavily to an exFAT filesystem (on my SD card) using it. I could very easily cause a kernel panic by, for example, taking videos or downloading torrents to an exFAT filesystem mounted using sdfat. I'm thinking that similar issues are occurring here.
Assuming that the issues are really caused by the update (I can't think of any other possibility), the only fixes/workarounds are to use a kernel with that update to sdfat reverted, or with whichever parts of the update causing the kernel panics reverted or a proper fix to the sdfat driver. We're still using an older version of sdfat, 2.3.0, over on the Tab A.2
I have an S7 Flat...with 18.1 ..7th April build...and ASUS Merlin with AI Mesh. I had issues with the S7 being the only phone that consistently dropped out. I changed on the router Adaptive QOS, QOS tab...Enable QOS to .off...and on Wireless, Professional Tab..Multi user MIMO to disable. My S7 now is pretty rock solid connecting to my home router...at 866 not 443 Mbps. I did read somewhere that the WIFI chip on the S7...was quite new when brought out and is not particularly stable with MuMIMO. My router is an AX88U...and this also worked on an AC66U B1...hope this fixes it for you...took me months to work this out!1
I never said that the update causes issues with 3.18 kernels exclusively, although I might've subtly implied that. In fact, I suspect that similar issues can occur on other kernels with the updated sdfat driver, including kernels based on 4.4.
Updating kernels to newer major releases of the Linux kernel for android devices is very much easier said than done. That would require all of the drivers and other bits to be forward ported, which is extremely difficult, time consuming, and requires quite a lot of knowledge, and there is a very high chance of there being issues after getting everything to compile, and even more changes would be needed to fix such issues. Android device manufacturers and SoC vendors very often make very extensive changes to their kernels, and this is true for Samsung as well as others, making things all the more complicated. Almost (think >99.9%) everyone has to go with their vendors older downstream kernels as a result - if it was so easy to update kernels to newer major updates, no one or less people on fewer devices would still be using older downstream kernels. Many are still using even older 3.10, 3.4 and 3.0(!) kernels on older devices with backports. Drivers could also be written from scratch, but that has its own significant set of difficulties.
The last minor update for 3.18 was actually 3.18.140, released on May 2019 (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=v3.18.140), and it was updated for that long for the many devices out there running on 3.18. The 3.18 Android common kernel indeed continues to get updates, including some fixes to security vulnerabilities. On my kernel for the Tab A, as a compromise, I'm also applying changes from 4.4 as well as changes from the 3.18 Android common kernel and previously also, when it was still maintained, Linux 3.16.1@Bleifuss2000
The settings are retained, you do not have to set anything new when updating. -

Take a note that a lot of LineageOS features have not been completed yet this is not a device bug and please do not report those
in this rom thread as you will be reported to moderator also do not post bug reports for known issues or bug reports without proper
a) Logcat
b) proc/last_kmsg (or proc/kmsg)
c) data/tombstones
d) dmesg
Also do not under any circumstances post bug reports if you are using substratum themes or unsupported magisk modules or you have performed any system modifications
Install gapps right after installing the rom itself dont try to boot to system before that if you want to use gapps
NikGapps and BiTgapps were both tested and working

I do this in my free time so bear that in mind when you notice I didn't fix known bug in next available build, Currently i work on this alone and i am not one of those kangers that just copy source and claim it as their own work,
if you want to support the project feel free to buy me some coffee paypal.me/ivanmeler
Feel free to join telegram group with early builds progress updates and some off topic stuff Join
Due to requests from some users I added signature spoofing support to the rom which allows usage of MicroG
you can simply install MinMicroG and grant it needed permissions for signature spoofing to make it work as intended
Based On Android 11/R
