ROM is running very good. But there are two problems when calling:

1. It's not possible to adjust the callers volume, and it is really low. //edit:// I'm aware of the attempt of some users here to fix the audio problem with the xml file, but it's also no working solution.

2. It's not possible to use speaker during a call, because then the mic is not working anymore.

Thats my best practice :) I always do a clean install.

1. Take a Backup of your phone

2. Boot to Recovery (TWRP)

3. Wipe > Advanced Wipe: *DALVIK, *CACHE, *SYSTEM, *INTERNAL, *DATA

4. Wipe > Format Data

5. Install the ROM Zip & GApps (e.g. via sideload Advanced > ADB Sideload and command "adb sideload app.zip")

6. Boot the phone to LineageOS

7. Check stability & functionality

8. Boot the phone to Recovery

9. Install Magisk Canary ZIP; Download here: https://github.com/topjohnwu/magisk_files/blob/canary/magisk-debug.zip

10. Wipe DALVIK

11. Boot the phone to LineageOS

12. Install None-Root-Apps (DKB TAN2Go, Circuit, Nine Work, ..)

13. Repack & hide Magisk Manager (if not working, deactivate Google Protect)

14. Use Magisk Hide-Function to all None-Root-Apps

15. Be sure, that developery options are deactivated

16. Check functionality

I ran into a problem when after restarting I can not unlock the phone. Cleared davlik, system and cache before installing the new version. The first boot after installing the new version was successful. Then the phone was completely discharged for several days. I charged and turned on the phone. At boot, the pattern key is recognized, but the standard launcher does not load and the pattern dots is shown again. There is no way to unlock the phone. Reverted to 20200603 version. Now the phone show message "Wrong pattern". Had dirty flashed 20200720 version again. The same result. Pattern is accepted but the launcher doesn't show. Had deleted lockscreen.db as mentoned at https://xdaforums.com/galaxy-s7/dev...-17-0-galaxy-s7-build-1-t3980101/post83113659 It helps me to unlock the phone.

I'm using pattern key and fingerprint to unlock the phone. Magisk and opengapps is installed.

Hi,

Don't know why but my schema lock was different after the last experimental release installation. I removed the locksettings.db in /data/system to be able to access on my phone again.

Hello. I came from Lineage OS 16.0. Installed it for daily use last weekend. One difference I noticed, the signal seems to be slightly weaker than in v16. It was always difficult to get signal inside my flat but not it seems to be nearly impossible.

I have a question. Is it possible to enable wifi calling or VoLTE somehow? Cant find it in the setting.

No other problems at all. Thanks for your awesome work.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Kippy51:
Settings, mobile network, calls over 4G (or how it's called in your language). If you enabled voLTE in status bar settings, it will show that symbol. At least when your network provider supports voLTE.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] winblocker:
The Network icon is not showing signal strength in the recent preview version of the ROM (maybe it did not even before).

I had Moro kernel 8.0.1 and 8.1 without any issue on previous LOS builds. Now I'm on new experimental build of LOS (see post #2 of this thread). This build is good for daily usage for me (except one time issue with pattern logon). Selinux is working fine. No wifi disconnects.

Regarding the recent experimental version of this ROM and the noted problem with taking any photos, is this just when using the ROM's own built in Camera app or does the same problem afflict any camera app you might install, such as Open Camera?

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] sailorpito:
First of all many thanks for you work, awesome rom!

I've just installed 0805(clean flash), camera and sound it is ok now!

I've set up a pattern screen lock to try encryption. Encryption went fine but when I use twrp it won't ask for the pattern I've set up earlier and so it can't access /data partition. Is it normal behaviour or maybe I'm doing something wrong..

Please let me know if you need any logs, thanks again

Still getting random black screens on my SM-G930FD :( , had to hard reboot with power + volume button. On LineageOS 16 i was getting random reboots once a day approximately. I wiped everything and just installed this rom (no gapps nor root, i had fdroid and a few apps (newpipe, slide, etc)), maybe there's something wrong with my device(?, stock rom worked fine

---------- Post added at 11:40 PM ---------- Previous post was at 11:30 PM ----------

By the way, before installing any custom rom, i was on stock nougat, i hadn't updated to the latest oreo, is it possible that i am missing some firmware update or something from samsung(?, should i flash a stock rom and update?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] girtsn:
Besides the FRP lock issue below (perhaps related to device policy app and changes in Google suite policies), build 11 was very stable no random reboots anymore. Thanks a lot Ivan, great job another donation on the way.

Upgrade to build 12 and back to open gapps went smoothly as well.

Fingerprint not working in some apps is a pain but has to do with Lineage itself I now understand from previous feedback.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] crazydrive22:
Yeah, you should flash Oreo via Odin. This will update your Bootloader.

You can also use this to re-partition your device, maybe a partition is damaged.

Download a 4 (or 5) Part Software from Sammobile or with Samfirm (only 1 part will not work).

Extract the PIT-File from CSC and put in to the PIT section of Odin. Also tick re-partition in the options.

Then fill the rest with the files you downloaded (BL, AP, CP and CSC, not CSC_Home).

Flash the hole thing and it's done. After a reboot, return to Download-Mode and flashTWRP again (via AP).

Reboot to TWRP and flash LineageOS (and all the stuff you need) from there.

And do a hecking backup before. :)

If Odin is stuck while flashing, try a different Version. In my case 3.14 was working well.

[Build 12]:

- Funny video phenomena when using Facebook Messenger video call:

I see my partner "Avatar"-like: Blue skin...

Seems like blue and red color are switched, green seems to be OK. More interesting: A taken screenshot of the video Avatar scene shows proper colors.

Using regular camera app for taking videos works properly.

- Is there a chance to modify NFC settings in libnfc-sec-vendor.conf permanently to

ISO_DEP_MAX_TRANSCEIVE=0xFEFF ?

I don't know the background as per default it is set to 261, which gives NFC extended length error for some apps.

To anyone with Magisk installed, after updating to the latest update, is anyone having ctsProfile fail but have basicIntegrity pass? I'm not sure if it's the ROM that's causing the failure or if Google updated Play Services so I'm just checking everything that's changed on my phone first.

Edit: Did a dirty flash as well, might that be the cause?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] sailorpito:
clean flashed latest update, both ctsProfile and basicIntegrity true
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Mr Creosote:
Awesome stuff, thanks. I just updated to this from Lineage OS 16.1 (clean flash obviously :D) Everything seems very stable and smooth.

The behaviour of the signal strength indicator is very different now. I live in a fairly rural area, where I have a strong H+ signal, but rarely pick up 4G/LTE. Where 16.1 was showing a full strength or nearly full strength signal, this looks like it's barely got signal most of the time, sometimes it goes up to maybe one bar. I can see from doing a speed test that there's no problem with the connection, it's just as fast as it was.

I'm not sure if this is actually a problem, or if 17.1/Android 10 just has different ideas about what counts as a strong signal? Perhaps it always counts H+ as a weak signal, and only considers 4G to be a strong signal? Is that possible?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] sponge4:
Thank you very much for your efforts!

I tried to install build 12 with latest gapps and I renamed the locksettings.db* files, so they won't be found.

The phone boots and asks for the decryption password, then a screen appears like (not exaxtly the words): could successfully unlock the partition but the data on it is corrupt. Please press "wipe all" to continue. You lose all your data, try to reinstall what is offered when you log in at google.

Is there a way to avoid this?

Thank you!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Jesus Krist:
What a update! Thank You very much [MENTION=4610599]Ivan_Meler[/MENTION]. ROM is great. Didnt faced any issues. Only smoothness of the ROM seems to be worse in the new build. Last time I tried build 8 and it was butter smooth.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chrisrevoltes:
I didn't test it, but I doubt it. This is not an official certified ROM, like those manufacturer put on the phones.

This isn't even LineageOS "official" (see here: https://download.lineageos.org/).

There are rumors that you can try to certify yourself, but this didn't work for me on LOS 14.1.

Besides does this make any difference in real wold? Not really.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Mr Creosote:
Sounds like it's probably not how it's supposed to behave then. I'm wondering if re-flashing the baseband would fix it. I've found some discussion of similar problems with a bit of googling, though not for the same device or android version. In those discussions, it was suggested that it's a baseband/radio firmware issue.

Seems to be no other problems with radio. I haven't used bluetooth, but GPS is working fine, hotspot works perfectly so far, it's much better than it was in 16.1, and no actual problem with signal strength, just with the indicator. I'll be going somewhere with a good 4G signal later, so I'll see what it looks like there.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Hemuli:
Did you read what the changelog says about signal reporting?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Mr Creosote:
I can see it says that there's more precise signal reporting, I'm just wondering if it is actually working as it should though? Because my signal indicator really isn't giving me useful information. There is no visible difference between a signal that can barely send a text message, and one that gives me a 23Mbps data connection with 51ms latency (my current speed). That's fast enough to comfortably stream 1080p video without buffering. I also often get latency as low as 41ms and speeds over 25Mbps with a H+ signal here.

The only way I can see that it would make sense would be if it only indicates a strong signal when 4G is available, and H+ is just always considered to be weak?

edit: just to add, I understand that there's a difference between signal strength and the data bandwidth that the network is currently making available to me. I'm talking about how this ROM compares to the previous ROM on this phone, and other phones on the same network. When I move around the area here, from indoors to outdoors, from being surrounded by trees to an open field nearby, there's either no change at all or very little change in the indicator, but I can tell from the actual performance that the signal strength is varying massively, and other phones/the previous ROM on this phone would show that variation with quite a lot of detail.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] qtdfiaui12:
Workaround: Go to Settings > Developer Options > Disable HW overlays (toggle ON). My games with 3D rendering also encountered this problem, it looked like an overlay since it disappeared when taking a screenshot.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Mr Creosote:
OK, I may have answered by own question to some extent. Just been into town where there is 4G, and the signal does show up as strong.

It still shows no change at all in signal strength when it has a H+ signal. Like I said, it's not necessarily a problem if that's actually how it's supposed to behave. I'm on a main road at the moment, passing by plenty towns, and the signal indicator just doesn't change at all as long as there's only H+.

I am wondering if it's just always showing the strength of the available 4G signal, even when it's connected to H+?

05.08.2020 build review

My 05.08.2020 build review - Updated my Canadian W8 S7 from experimental to the new build, all dirty flash. Then I installed clean while troubleshooting (and I don't think that was necessary).

Notes:

- I installed Gmail, the Google Dialer, and the Google Messenging client. I'm using the nova launcher. I don't miss AOD. Using DDG as main browser.

The good

- Hats off to the developer Ivan Meler - amazing job. Very smooth, fluid. It is a brand new phone. I am loving it.

- Fingerprint works as advertized and more reliably than stock.

- Fantastic that the SD card is now used as contiguous RAM. When I boot, I get a message that the SD card is missing but I learned to ignore the message.

- Android Auto is much more reliable.

- No problem casting (tried youtube).

- Battery life is improved.

- Previous call volume issues are resolved.

- Wifi and Bluetooth are working very well.

- Installation went smoothly. Did not have any passcode issues since I had resolved those when I installed the experimental build. I did not see any update about the Gapps problem previously posted, so I continued to use a slightly older version of those (June 30).

Issues

- The notification lights are not working, except for charging.

- Although the camera is launching now, it does not want to capture pictures (and cannot access SD). I installed GCAM for S7 and that is working well so no worries there.

- I realized that security was not passing. I understand that is expected with Lineage, and has nothing to do with this build. I installed Mag* and after Googling I found the props fix that completely resolves this. So now Google Pay is working for me.

- My Gear S2 watch cannot work with the phone, I can't get passed the "modified" message when the app starts. I followed the instructions on post t3743138 but Samsung Gear still refuses to open.

Minor things - these are very minor

- Great that the experimental build issues with some photos on web pages getting glitchy are now resolved. However, there is still a tiny bit of glitch still. It is barely noticeable now as it fixes itself almost immediately when it happens. I think photos selector views that let you switch left/right (e.g. Amazon or some news sites) are most affected. Very, very minor.

- Very occasionnally the phone takes a few seconds to wake up, making me think the phone is powered off. But then it wakes up and everything is normal. I must have noticed this only about once a day so far. No big deal.

Overall I am really pleased and will be sending coffee!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] cobrarx8:
To solve the issue with the modified message you need to change the fingerprint of your device. Do all these steps given in this post except for replacing the strings. Replace only ro.product.manufacturer with the "google". Then go back and pick 1, then type f choose 7 for google and pick 22 for Pixel 4. Restart and you can open the Wearable app to pair your Gear S2 https://xdaforums.com/showpost.php?p=78024599&postcount=7
