By screen fading away do you mean it goes black?

If yes, dont use reading mode or anything that makes screen greyscale like bedtime mode.

If you mean the screen is sometimes unresponsive (sort of) after a reboot then ive noticed it only happens if you touch the screen while on the boot animation.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Cap'tain Champi:
Yes, it goes black.

When the bedtime mode turned off by itself in the morning, it went back to normal.

Didn't understand at first but you are right!

I will be aware on that point now! Thanks for your answer :)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Cap'tain Champi:
Also I figured out how to set a battery limiter for charging when the phone is on, like on lineageOS 18

By default it is at 75% maximum, it can't charge up to this value. If it was already higher than 75%, it will maintain the battery charge.

One method : go to TWRP > Advanced > File Manager, go into /data/adb/service.d and create a new file here : folder icon on the bottom right, open the terminal here and type "nano battery-limiter.sh" (file name as you want), it will open a notepad where you can type "su -c echo 1 > /sys/class/power_supply/battery/store_mode", save your changes (CTRL+O) and quit the terminal (CTRL+X). You can restart the phone

By typing that in this folder, you will set at every boot the value "1" in the file called "store_mode", otherwise if you set this directly in the file "store_mode" it will be overwritten to 0 on the next boot.

If you want to change this 75% maximum value, you can go into the same file in service.d folder and write another line in battery-limiter.sh to set another value (like 80) in the file store_mode_max.

"su -c echo 80 > /sys/class/power_supply/battery/store_mode_max"

I haven't tested this, 75 is okay for me.

Thanks to Ivan_Meler for the method, already described months ago in this thread :D

Thanks for the efforts with this ROM, it runs really well!

One thing I've noticed is WiFi seems to turn itself off every now and then. When it does, I need to restart the phone to make it work again. Unfortunately battery usage is much heavier on 4G so it results in battery drain when this happens.

Any suggestions as to what might be causing this?

So I accidentally flashed lineage-20.0-20220908-UNOFFICIAL-herolte.zip over the top of my regular working S7 running the previous build of 19.1 from this thread last night... It was late and I was on autopilot so I just blindly downloaded the top result from Ivan's download page and flashed it via adb sideload all without registering I was flashing the wrong image. Pretty funny but pretty dumb - unsurprisingly it didn't go well 😂

I'm not that bothered as everything important is backed up via nextcloud and it kind of needed a clean reinstall anyway but I would like to get back into the data partition to have a poke around and maybe grab some configs, etc. Before I bite the bullet and just wipe/reinstall it anyone got any suggestions?

Before the bad flash it was running twrp-3.6.1_9-0 + lineage-19.1-20220806 + Magisk 25.2 with device encryption ON - which seems to be the main problem now.

I accidentally dirty flashed lineage-20.0-20220908 over the top which resulted in not much: 20.0 isn't compatible with encryption I understand so it started boot but never asked for the unlock key.

I upgraded twrp to the latest twrp-3.6.2_9-0 which didn't help and then just went ahead and dirty flashed lineage-19.1-20220907-UNOFFICIAL-herolte.zip over the top of that. Currently it boots and accepts the encryption password again but unsurprisingly boot loops after about a minute of starting up.

Additionally I don't seem to be able to do nandroid backups via adb through twrp which I was going to use to dump the various partitions out separately to restore later. In fact on this phone with twrp and Ivan's roms I don't think I've ever been able to access or mount /data via twrp - is that normal?

Anyway are there are any clever ninja tricks I can try here to backup/restore my data partition onto a clean install or even dd it out via adb or something? The phone does at least currently have the ability to decrypt itself and start boot.

And if anyone was wondering if it's possible to dirty flash 20.0 over the top of 19.1 with device encryption in play I can at least definitely answer that: no, you most certainly can not!

hi everyone !

i don't know how to search in this topic/thread (you can tell me how to).

i have an issue with this rom. The fingerprint scanner work only one time.

I tried wipe cache (art/dalvik), reboot, use shema to unlock and after in sleep mode, normally i'd be able to use my fngerprint to unlock, but it don't work. I can fell the vibration and that's all. i have got 4 fingerprint registered. If i delete one, i can't registered another. button menu grey. I can't do anything.

So i reflash the rom. Wipe everything (system, data, etc...). After that, during configuration, i able to registered fingerprint. It works one or two times. After that, it don't work anymore.

have you a suggestion ?

I use flamegapps 12

No magisk.

thank you for your help.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] meesam3379:
If it's about adding multiple fingerprints

Afaik there's a limit
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] harnis:
It's not about that. My fingerprint scanner don't work. If i delete one or two or all my fingerprint registered after i can't add one. Menu buttons are "grey" (can't tap on it).

I think i made a mistake but i don't Know where. I will try lineage 18.

If somebody had a clue, it will be nice. Thank you for your answer.

Same WIFI Problem here.

1-2 times a day Internet connection gets lost, but WIFI is still on and connected to the Router.

It only happens to Lineage 19.1 Galaxy S7, other devices using Lineage 17 or Android are running fine.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] pawelluk:
I have an issue after encrypting, and then going back and flashing rom again. Seems that I have no network, and did check that baseband and IMEI is still there. Not sure what happened. Did a bit of a search on here, but no helpful guides.

Is there a way to check the EFS partition against some kind of a layout it should have, what files should be there? I did a backup, but it might have been affected - not sure.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] netra3441:
Hi,

this WiFi issue is not in LineageOS, it is a special hardware problem of the Samsung Galaxy S7, I had also in StockROM (was Android 8 Oreo) and have it actually in LOS 19.1 in Ivan Melers great version too.

Many thanks to Ivan Meler, and my greatest reverence to him and to all those, who make LOS possibe on all compatible hardware. I am an elder and severly handicaped person, I have not the money to buy new hardware, and your folks great and honest work helps me to have actual Android on my seven years old Samsung Galaxy S7, wich still runs properly.

You guys do a good and honorable work expecially for those, who cannot allow oneself a new hardware.

Great work, folks, I really appreciate this!!! Thank you guys so much!!! Thank you, Ivan Meler!!!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] harnis:
So... i downgrade to lineage 18. And everything works great. Fingerprint scanner works perfectly.

Very smooth and fast rom.

Thanks for Ivan Meler. You had done a perfect job. I'm so grateful.

Hello, I installed this ROM a few days ago : for now i did not found any issues, thanks your for your clean work :)

Fingerprint is working, no wifi issues, good battery life.

About phone echo, neither me or the other had any with basic or signal calls. I only found one Friend having echo on his side, but it seems to be an issue on his end (he already reported it before i got this Rom)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] niz321:
Okay I spoke too fast, I got an issue that seem to have been encountered in this thread about vibration level : none of the levels available in accessibility settings are working for me. Phone vibrates in twrp, but not in rom

I am still trying to find out why.

Edit : found it, battery saving mode disables vibrations.

Is there options to have some power saving mode without disabling vibrations ?

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Kenajcrap:
This issue persists on the latest patch. A new full adb logcat from app launch all the way to the moment error pops up is attached, lmk if I can give any additional information to assist with debugging.

The first pertinent error seems to be

keymaster_tee: [ERROR]: (nwd_keymaster_tc_api.c:1913) KM_TZRunCommand returned -28.

I know literally nothing about any of this, but TZ normally refers to time zone.

Could this be the key manager not handling different timezones correctly and that is why this has not been fixed for me yet? I'm in UTC -3:00 if that helps with troubleshooting.

Thank you a ton for the continued support.

Hello @Ivan_Meler

I hope that you are doing great.

First, thank you very much for this great custom ROM that revived my phone from the brinks of death.

Actually, I have a little problem with the latest version of this ROM, when I try to place a call while using a Bluetooth headset the call goes on normally but with no sound on the headset, I wasn't facing this problem on the 07.09.2022 version, on the other hand the headset is working normally when I'm receiving a call and on all the apps like YouTube, WhatsApp, etc ...

If you have time to spare, It would be much appreciated if you could include a fix for this problem in the next release.

Thanks again and have a great day
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Massedil:
Hello everyone !

I can confirm that with the last October update, the GPS is working again fine, thanks.

But I now also experience a strange behavior with the Bluetooth connection : when I connect the S7 to a Bluetooth speaker to listen to music, it is very very laggy so it is unusable. The same Bluetooth speaker works fine with my S5 on LineageOS 18.1. I tried to change Bluetooth parameters in the developers options menu but without success. @Ivan_Meler, do you know what can happens ?

Thanks
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] droopy4096:
just switched from 18.1 to 19-20221005-UNOFFICIAL-herolte (seamless upgrade all in all). Quick observations:

* Bluetooth reliability improved over 18.1 experience

* battery life reasonable

* lost ability to configure camera to save to SD

* overall there's a sense of minor lag, almost imperceptible but I can swear it's there.

* some UI oddities are likely 19.1 - specific and not this port-specific.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] droopy4096:
One thing about Bluetooth : since 18.1 my car audio stopped displaying currently played songs/audio info. Not sure whether it's newer android "feature" or deficciency of LOS or something to do with this port to sgs7

Quick heads up everyone: the latest twrp-3.7.0_9-0-herolte.img is broken.

https://github.com/TeamWin/android_bootable_recovery/issues/270

You can re-flash the previous twrp-3.6.2_9-0-herolte.img over it if you run into this issue before it is fixed.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chairmanmiaow:
And while I'm here I thought I'd post a belated follow-up to my own post from a few weeks back and basically recant the whole lot of it.

As I had complete backups anyway and had nothing to lose I experimented a bit longer with (very) dirty reflashes of a few different combinations of lineageos/gapps variants and despite having encryption enabled I pretty quickly hit a working setup that not only worked to get back into the phone but fixed everything so well I actually carried on using it for a couple more weeks before doing a full rebuild properly.

The only thing that didn't work after reflashing 19.1 and opengapps back onto the trashed phone was the good old broken google play store ("you are offline") issue - hardly surprising considering the circumstances. All the actual apps worked fine so the only thing missing for those two weeks using the phone post-disaster was google app updates and frankly that wasn't worth caring about.

So if anyone was wondering if it's possible to recover from accidentally dirty flashing 20.0 over 19.1 with full encryption enabled surprisingly the answer is actually "yes".

I'm sure none of the rest of you are actually dumb enough to do what I did but just in case anyone does, it's not actually game over.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Kenajcrap:
If I'm not mistaken, the "now playing" feature is only available if the Bluetooth controller is using AVRCP version 1.4 or up. Head over to the developer options and check which version it is set to. I'm unable to check for myself which one is the default due to an unrelated issue in this ROM.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Kenajcrap:
I normally dirty flash it on top of the earlier one. After doing a full TWRP backup, of course. Kind of a pain in the ass having to extract the boot.img, patch it with the magisk app, then zip it again and flash with TWRP. But since I only do it every few months, it's not a big deal.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] mavvy4ever:
Did you flash 19.1 oder 18.1 via TWRP? Or did you do a clean install with wiping first?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Ex novo:
If you have TWRP recovery installed just rename Magisk-v25.2.apk to Magisk-v25.2.zip, save it on external storage if ROM is encrypted and after update restart on recovery and flash Magisk zip.

Is it possible to easily fix 4K recording?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Hildi60:
Hi,

I m very happy with the Lineage OS but I have 2 issues which I didn t get solved

1.

I always get notices from "Seedvault" that a backup of the phone cannot be proceeded - although I have choosen in the settings

(System - Backup) my google account.

Can somebody help ?

2.

Since installing the latest LineageOS 19.1 from Oct 05 I experienced the following problem.

In areas with no or a very weak mobile signal My Galaxy S7 stops working - dark screen with a small clock - no reaction on f.e. (on/off - volume up/volume dow - Home button). The battery gets very warm. The only thing what helps is a restart.

how is this Rom compared to v18, stability/bug wise?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Hildi60:
Sorry i didnt express myself precisely.

I installed 19.1 in early august 2022. Then I updated this 19.1 in August, September and last at Oct 5. I did that with the <settings-system-updater>

The first issue I had from start in August

The second issue I had several times after oct 5.

But I cannot replicate it
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] netra3441:
Can it be, that beside the mobile connection you also keep active always your WiFi, when you go outside?

A lot of people here in Germany do so, they keep the WiFi always active, when leaving their homes, and then they worry, why the battery goes low.

This is, because the WiFi, when kept active, always searches for a connection, does not find it, and this operation empties out the battery. The WiFi is not an intelligent system, it does not recognize, that outside mostly there is no available connection, so it searches, and searches, and searches, and that costs energy.

So, try to switch of the WiFi, when you leave your home, and just use the mobile connection. WiFi use just there, where WiFi really is available.

Same with the mobile connection. If you are at home and have WiFi there, switch of the mobile internet, this also saves battery, but mobile costs too.

Another thing is, that people go outside with just a half charged battery. This happens, if one has only one charging unit at home. I have several charging units in my place, in each room, so I always simply can charge the battery, so I never forget to charge.

I hope, that helps you.

I have done some tests about the Bluetooth connection to speaker problem.

The same problem occurs if I try with another Bluetooth speaker, so it seems it is not related to the speaker.

But, interesting thing :

- When S7 screen is ON, there is no sound problem on the Bluetooth speaker (or very rarely and shortly)

- Problems occurs when the screen is OFF : the sound is laggy and cut

Is there something related to battery economizer when screen is OFF ?

Hello @Ivan_Meler

thanks a lot for your great work on the S7. We all really appreciate you!!!

I actually still run the LOS 19.1, because I will wait until I can buy another used S7 so I have always a backup system. Because of my physicial handicaps its actually important, that I always have a reliable working mobil phone ready to hand, and your LOS 19.1 works so properly on my S7, so that I wait with upgrade to your LOS 13, until I have a second S7.

Greetings,
