Okay guys, I have a really funky and 100% reproducible bug here. (On my device, anyway)

While bed time mode is enabled (including black&white screen which I intuitively presume is relevant, haven’t tested it though), any reboot of the phone will result in the lock screen being visible for a tiny bit but then it quickly fades to black and *stays black*. The touchscreen is still usable if you’re enough of a psychic to know where you should touch, but it’s pitch black. Until bedtime mode is disabled as per the settings, or until I manually disable Digital Wellbeing. What I can confirm is that pm uninstall -k --user 0 com.google.android.apps.wellbeing works to restore the screen.

I updated to this lineage 20 ROM afterwards while the issue was occuring (and used above workaround afterwards) so I assume it also applies to the lineage 20 ROM. Is this a ROM specific issue, or a LOS/Digital Wellbeing issue? Seems like a major bug like this should be more well known if it applied to everyone though. Can anybody confirm this?

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Ivan_Meler:
digital wellbeing/ night mode is not part of the rom itself gapps probably lack overlay for minimum brightness
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chomsky55:
adb sideload lineage-20.0-20221004-UNOFFICIAL-herolte.zip serving: 'lineage-20.0-20221004-UNOFFICIAL-herolte.zip' (~21%) adb: failed to read command: Success

and on the phone it just says: patching system image unconditionally...

It's not running anymore but the blue bar is still animated..can't exit or restart the sideload, The md5sum checked out fine. After a forcefull reboot I of course end in a bootloop. Rebooting to twrp and sideloading the zip again gives the same error and same bahaviour it just exits at a different percentage.

Does anyone have a link to the previous update?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Ivan_Meler:
shouldve used ota or flashed it without sideload, rom itself works fine tho adb on your host pc messed something up while serving update likely
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chomsky55:
I always sideload and it always works out fine. I'm on the latest adroid-tools package...I use Arch btw

EDIT: After downloading the zip from github and trying again it functioned this time! The other zip I downloaded which failed was from Mega. Weird thing is that usually the phone stays rooted but not this time.

Found a bug on the camera app. When I tap on the photo I just snapped, it doesn't bring up the gallery app (no photo preview).
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Kippy51:
For me it works; even get a pop-up were I can choose which app to open with: gallery App or etc. And just once or always.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] vizolover:
Thanks for the reply, I found the culprit. It was Gcam Services I had previously installed in order to use a Gcam port. It apparently takes precedence as the default app to open the preview (having Gcam services makes the OS think you have Google Photos installed and even get a prompt to update the Google Photos app). As soon as I uninstall it, it works as expected.

But I found another bug where my selfies (from the stock camera app) are coming up in the wrong orientation. 🙃
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Kippy51:
You might be right there .. My selfies get turned 90° to the left @Ivan_Meler

cant reproduce that
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] master373:
Do you use stock camera app or an different app like gcam port, open camera etc ? What gallery app do you use and which camera settings do you use ?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] vizolover:
Yes stock camera app from the latest build. Selfie can only shoot in landscape orientation. Opencam and gcam work as expected. Stock gallery and Simple gallery pro produce the same result, stock camera settings.

Video on the other hand has the correct orientation 😂
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Techguy777:
do you guys have Bluetooth problems? I have had it stop working all together. IT will not find devices. It works at first then after using it for a few hours. It also happens on my poco f3 so I believe android 13 isn't working right. I do like the rom though.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Techguy777:
I also have static when playing music. I did get it working by clearing the data for Bluetooth 13 app
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Techguy777:
Its been a few years since I played with the S7. Did it get only like 3 hours of battery Life? The apps say its using 33 percent battery an hour. Is that the rom?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] netra3441:
Hello Forum,

just have a question for understanding the right way:

Actually I run my Samsung Galaxy S7 with LineageOS (LOS) 19.1 and NikGApps 12.1.

For installing LOS 20.0, must I do the install from scratch?

Means, first install newest TWRP with Heimdall and then the LOS 20.0 plus the corresponding NikGApps 13?

Or can I just load the installation file of LOS 20.0 and of corresponding NikGApps 13 onto the SD-Card of my S7 just to do the upgrade for both with the built-in LOS 19.1-upgrader?

Greetings

Hey, I was wondering if you could add a blue light filter where the screen goes orange. There's gray-scale, but I believe that's not effective at reducing the amount of blue light.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] przvl:
I've been using the rom for about two weeks now and got two bigger issues:

While it worked fine in the beginning, I'm getting massive slowdowns now from time to time, anyone else has related issues? For me it happens especially with the camera and Telegram (when using reactions, my keyboard won't work for several seconds).

edit: I wiped Cache + Dalvik-Cache already, but it doesn't help.

Second issue:

The flashlight will turn off once the screen gets locked or turns off due to inactivity. I guess this is a bug and not a feature, right? I read that there are issues with long-pressing the On/Off button for activating the flashlight (which worked in previous LOS versions), so is this related to it?

Besides that the rom looks and feels great!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] zehkul:
For the phone sometimes hanging issue (it also results in bluetooth underflows and hence choppy/missing audio while the screen is stuck) I tried getting some logcats from the moment things started going south. Apparently the phone hangs so hard that logcat timestamps are jumbled up.

Doesn’t seem to be highly dependent on which apps in particular are opened, just on the system (RAM?) being under heavy load which it doesn’t deal well with.

My device is set to german language, so i didn't know how exactly its called. But search for settings -> display -> colors and activate nightlight
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Dom Elder:
Oh wow, thank you. I didn't find it before
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] przvl:
Good to know I'm not the only one with this issue. I assumed these lags are not tied to specific apps, but it makes sense that e.g. camera app requires a lot of ram. I hope we find a solution for that.

edit: I checked the Memory usage in Developer Options, and after Android OS (~1.1GB), Telegram is the second most memory demanding app (~700mb). It makes sense lags happen when there are issues with memory handling.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] netra3441:
Hi @dan54140

thank you for your response.

Actually I run TWRP 3.6.1_9-0-herolte on my S7, and I wonder if this would be ok for the LOS 20 too?

I have upgraded several smartphones for friends to LOS, but in each case from StockROM.

With the LOS 20.0 and my own S7 this would be the first upgrade inside the LOS, therefore I was unsure, how to handle.

But I still have downloaded newest TWRP for the S7, its 3.6.2_9-0, and also LOS 20.0 and the NikGApps 13, and in next week I will do the upgrade.

What I really miss, would be an LOS upgrade system like with the StockROM, so that one must not install everything new, because this is a damn bunch of work, and as a handicaped person I try to avoid such long periods of sitting at my desk... ;)

Greetings to all

Hi @ssauger,

I am from Germany also, but because English is the ruling language here, I reply in English.

Could you please tell me, where that settings for the nightlight is to find with the german language menue?

Or is your S7 in LOS 20? I still run 19.1... will upgrade next week.

Greetings

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] ssauger:
Yes, my device has LOS 20 installed. If it is also available in 19.1, i think you will find it in Settings -> Display too.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] netra3441:
Thanks, have found it in 19.1 under Settings -> Display -> LiveDisplay -> Display(Screen)mode -> Automatic

(in German: Einstellungen -> Display -> LiveDisplay -> Displaymodus -> Bildschirmmodus -> Automatisch)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] przvl:
It's always recommended to do a clean install (wiping data and installing from within TWRP) when changing the ROM or LOS version (e.g. from 19 to 20). But once you run a version (e.g. this LOS 20.0 version), you can install regular updates from within Android without having to wipe anything first.

Signature Spoofing is a feature required by a very popular open source app called microG, which allows the user to use apps that require google services without actually having to use google apps.

There is a very clear explanation of signature spoofing here, but be aware that signature spoofing is a contentious feature, and the blog post linked is opinionated.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Privacydroid:
Thanks for the info, i will read that.

I heared about microG but didn't know it's releated to signature spoofing.

So signaturespoofing is mandatory for using microG ?

Anyway, i preffer not to use microG, nothing from google at all is the best choice... (opinionated i guess...)

So will all the future builds be called signatue spoofing instead of alpha beta WIP or stable?

I asume, it will say somewhere if the build is stable or not anyway?

I'm on LOS 19.1 was thinking to update to 20.0

Does the camera record in 4K
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] master373:
No the stock lineage camera supports only 1080p. If you relay on camera the samsung stock rom is always the best choice in terms of quality
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] netra3441:
Well, the Samsung Galaxy S7 has a hardware bug in the WiFi, so that on some S7 it drops.

Same with my Samsung Galaxy S7.

Its not a problem of LineageOS, its a hardware problem in the S7, what was present on some S7 also when using the StockROM.

Excuse me. It was not my intention to mess up this forum with useless posts and to take up your time. I have therefore deleted my post.

My apologies once again.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Ivan_Meler:
dont you think comparing binary files where source for every file is available is a bit counter intuitive, let alone the fact you didnt compare actual files and just their existance and that you didnt even compare actual audio effect files, i really didnt want to have to explain this for i dont know which time but you were sort of pushing it

To everyone who is facing the issue of apps not opening, I isolated the cause to be formatting SD card as internal storage. Right now you can only use SD card as portable storage.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] netra3441:
Well, thats pity!

In LOS 19.1 this works properly, and just this feature makes the S7 with its low internal storage really usable.

So, actually myself I cannot change to LOS 20.0, because I really need this feature (SD card be formatted as internal storage).

Friendly request to @Ivan_Meler : Is this an issue maybe to be fixed quickly?

Greetings,

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] master373:
Well when i remember correctly Android scratched the possibility to use an sd card as internal storage or changed some internal stuff that broke it on Android 13.

If it was easy to fix ivan would do it.

Remember he is doing it as an hobby and has probally other prioteries
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] netra3441:
As working long time in the IT, I know really good, what a tremendous great work @Ivan_Meler is doing.

My Samsung Galaxy S7 with LOS 19.1 (Android 12) works properly with an SD card formatted as internal storage, and I do not know about, that in Android 13 the manufacturer (Google) has changed that.

I am also very sure, that Ivan really knows by his own, what to do and when to do, and furthermore, as a grown up man he really does not need a warranting spokesperson.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] cps2x:
I stayed on v16 during this time and recently when updating I discovered the problem, I have tried from v17 to v20 and indeed they all have echo. We must have a specific hardware, I do not know if it would be useful to give information about our phones but at this point it seems that there is no interest. In any case very grateful for the work done.

Hi,

I've installed the latest release, 20221119, and it's working almost perfectly! Awesome. I've made a full wipe/clean install with NikGapps and I don't regret anything.

Sometimes I have troubles to unlock the smartphone by swiping up, like a small lag in the wipe gesture. Firefox and Google Maps are a bit slow, but the S7 is getting old.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] MastahMatt:
I must weigh what I said previously. When using the camera, I have serious lags and sometimes, Application Not Responding. I've tried the stock photo App and the Google one, but the behavior is quite unpredictable. When it's working, it's working for both Apps, when it's failing, for both Apps too.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Devolix:
Hi @Ivan_Meler

Thank you very much for this nice work! It's impressing to see what people can make possible these days. My friends don't believe me, when I tell them I'm running latest Android 13 on my ancient phone. :) I love it and I'm glad to have an up-to-date security patched device without buying newer one in times everything becomes expensive, more and more. Keep it up!

Although I have a question.

While re-flashing to 20 from the 19.1 build, I noticed the camera quality worsen again. From stock to custom it already went bad, but later it got improved. I'm not sure what exactly it causes and how it can be fixed. It looks like a post-progressing filter what altering the image. Here you can see what I mean, left stock-image, right current build: https://ibb.co/f0P23LW

Is there a chance that you can improve the camera same as in the other builds? I've time and can test builds or donate/pay something if that any helps. Let me now. :)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Ivan_Meler:
oh hey post processing itself didnt change but the app did, check the settings in default camera app, it has 3 modea if i recall correctly zsl,fast and quality.

try setting it to quality you should be getting way better results by just doing that.

there are also apps that are way better than stock camera app like footej, gcam ports and even opencamera
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Devolix:
Thank you for the fast reply.

Unfortunately, nothing of it changed anything to it ("max quality" basically just doubled the file-size):

(Left to right: Setting to fast, Setting to max quality, Footej, OpenCamera: https://ibb.co/M86cMv8

When zoomed in, you can see the texture is like fissued: https://ibb.co/yBB7Qpw

It reminds me, when I'm using magical erase function in my photo-app on computer, on areas with several different textures or just by a large radius, the app overlays parts of it somehow, that is why my guess was post-progressing, here you can see what I mean by the magical erase fail: https://ibb.co/fYhZxLf

On the phone: Its like the system tries to correct/optimize the whole picture by applying this erase-thing endless times all over the place and making it worse that way. Since, it seems its in every photo-app, maybe it has to do with the drivers in android? Sadly I've no idea how the stuff works, so I'm just guessing. In the 19.1 builds the noise was in as well, but got reduced/softer after a specific build:

- Android 8 Stock: Fine

- LineageOS 19.1: Heavy noise

- LineageOS 19.1 (I think it was since 29.03.2022): Little noise

- LineageOS 20.1 Heavy Noise.

In the changelog:

- "Switched to source built camera provider lib"

Maybe it could fixing it here as well?

It could be also the case that it depends on specific phones, each model using different drivers for stuff, or any like that. Few months ago I have read here about audio issues. Some people reported that the caller has echos in call. (I have the same issue, but it not bothers me really - it just gave me the idea it could different on several phones, since other people reported the audio is perfectly fine for them)

Im using SM-930F (UK Import), phone says also "Hardware version 8", whatever it means. Hope that helps to identify the problem more. If you need any more tests or information, let me know. I would like to help. :)
