beta build, waiting for stable

Hello, I'm a huge fan of the whole rom, I always test and install the latest builds, but I'm less concerned and more happy with the final stable build. When I installed the last build I was constantly getting this weird display glitches: color bars, screen blackouts, random crashes, reboots and so on. I wasn't getting these problems with the other builds. Tried to reinstall the rom couple of times, still having the same problems. So I wanted to wait for the official build or any suggestions.

Thanks! for any replies. ?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] fer493:
Hello, thanks for the build. It is excellent. Any idea when this will move off beta and be considered stable? Thanks.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rho-bot:
Guys, SW will never be "stable" (in terms of bug-free). Even on official LOS, thy stopped years ago from having a stable release, there are only weeklys or dailys (depend on the build roster).

Forget about the "Beta" label in the thread headline. Try & report issues with logs, to improve this ROM.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] jaroulz:
Guys, I have a big bug since I've updated with the latest MOD version: when I initiate a call by touching the phone icon next to the contact name, nothing is happening... except that it is actually calling in the background! So I can call but I have no way to manage the call on the screen, no way to hang up too! Does anyone have the same issue and how to solve it?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] gentlelord:
Is That The Only Bug You Have Observed/ Discovered So Far ?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] jaroulz:
Solved, I had no default calling app in the settings... Now that I've ticked Telephone, everything is fine.

Other bugs were low volume (had to edit the .xml file as usual), volume changing from low to very very low (need to reboot to fix it) without apparent reasons and phone total random freeze (need a forced reboot).

Build 9 is working fine, no errors so far, random reboots are also gone.

Are you aware that the signal strength for WiFi is working but not for Network?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tvfan1:
Hi, How were you able to manage the low volume issue? I applied the new XML file that was posted here but it's still super low- can I change the values in the XML manually and if so which settings ? Thanks!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] jaroulz:
just go to system/etc and edit the mixer_paths_0.xml like this :

open the xml in a text editor and replace all

Volume" value="26"

by

Volume" value="32"

save and reboot

Mine replaced 30 values in total.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] drgonzo69:
Hi,

I installed latest build and everything works fine but I can see that different networks strength are all weak (wifi, 4g and bluetooth with LDAC in my case). I have some wifi loss that i had not with stock samsung firmware.

Did you experience these problems too?

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
General and usual reccomandation is to update baseband, you may download the latest stock ROM on sammobile and then flash just the modem files

Will there be an google play protect certificate update in the future?

Because some apps are disappeard from the playstore since i installed the rom.

Best regards, and thanks for this great rom!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
To solve this problem you need to recertify your phone with google, follow this guide: https://www.phonearena.com/news/Reg...d-services-Android-certified-support_id104243

mic picks up speaker sound on call when on speaker phone

First of all, swell job on the ROM.

This is by far the most stable Android 10 ROM for S7 right now, but I have one major issue.

I experienced one issue with LOS 17.1-20200506, while on call the other party can hear my phone's speaker. Also every once in a while there is echo that the other party hears while I am on speaker and the while I am earpiece the other party will get echo randomly every once in a while. This was tested on Regular Call, Hangout, WhatsApp and Messenger.

How can i turn off the softkeys permanently? The app "buttons light and touch" does not work.

Thanks in advance
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] lilithsspawn:
Are you sure this is a certificate problem? Is your system rooted? Some apps like Netflix don't show up if the system is rooted, and a solution would be to download them from the Aurora Store.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
That's OK, GP jeep saying device not verified on my phone as well, seems to be normal.

After the procedure, did you try to reboot the phone and search for the apps you wanted?

I had the same issue with Netflix and I fixed with that BTW.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Zuikkis:
Install latest version of Magisk (canary branch, 20.x). Then enable Magisk Hide from the Magisk Manager.

Check that you pass Safetynet check in Magisk Manager.

Then clear all data and cache for Play store app, and reboot. Then restart Play store, and it should show that you are certified, and Netflix is available.

This has worked for me with most of the custom roms, including this LineageOS 17.1. All bank apps and Pokemon Go work..
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] drgonzo69:
Thanks for your reply rdelmont.

For now I rolled back to Lineage 16 which seems more stable and with no network problems with my phone.

When version 17 is flagged as stable I'll try it again and I'll flash modem files if I still have network problems.

Thanks!

Hi I want to get some logs out of my phone so that I can report a bug or two, I have read the How To guides but they are bit out of date and I can't find a proper LogCat program for my phone.

My phone isn't ROOTED so I need one that will work in that situation, can someone please recommend an APP I can use.

Hi

I've installed build 9 and it seems to be better and more stable than previous build, thank you again Ivan! But the old fingerprint issue remains, some (all?) apps will not install fingerprint as an authorization method. The fingerprint is accepted by the setup and recognized by system, but when it shall be validated by auth system it fails. Since I'm new to forum I'm not allowed to add the log as an attachment (??) but can I add the critical part below even if I'm really aware of the rules and should avoid this, hope it will help the dev team.....

This is the log from KP2A trying to set fingerprint as auth method, encrypting step, where it fails (sys returns -3) and shows some cryptic text, completely nonsense....(should have been "function not supported by system")

The masking is by my me!

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
Needless to say, but for S7 we have 19 variants all around the globe, each one with hw differences from the others. That's why sometimes stuff works and sometimes does not... In that case, grab logs and attach here, maybe Ivan will get to fix the issue
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tvfan1:
changed , saved and rebooted, works great, thanks!

BTW- is 32 the Maximum? what will happen if it'll be changed to 36 (to make it even louder) any risks?

Thanks again!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] jaroulz:
I never saw anything higher than 32 in terms of volume value in the xml so I would not go further, it might ruin your speakers.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tvfan1:
Thanks [MENTION=5184683]jaroulz[/MENTION], I will keep it as it is. with this minor tweak it's the best ROM I've used in a while (better than LOS 16 IMHO)

Hi,

I flash yesterday and everything works great.

My phone freeze (had to force a restart) at the first login on instagram but now i'm logged there is no issue.

Is this possible to root my phone on this version ?

I already tried to flash an old opt-encrypt without success.

If one of you have a working tutorial i would be gratefull.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Timthedog:
Hi

Continue investigating the fingerprint issue. The errorcode -3 stands for "right fingerprint, wrong system" and is connected to the keystore that isn't possible to access or wipe easily. The error is probably generated in the basic AOSP of LOS and maybe not a issue for this forum.

Anyway it points out that there are fingerprints not connected to LOS in keystore database that match the key requests from the apps. So my problem is probably that I forgot to wipe fingerprints in my previous ROM.

If I 'm right I have a couple of questions :

LOS itself seems to handle this problem. How is that done and can it be used in app API?

Is there a way to "clean up" the keystore without knowing the keys?

The only workaround is probably to restore old ROM system and wipe the fingerprints used in that system. Or is there another way?

In general installation instructions it's stated that security locks shall be disabled before installing new ROM. But maybe it should be stressed that old keystore keys must be wiped out as well? Or have I missed that information?

This issue is in AOSP part of the system. Which is the correct forum to address it?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Zuikkis:
Nah.. I don't believe this. I have never wiped any fingerprints when changing between roms. New ROM always asks fingerprints again. This problem would be much more common, I doubt anyone wipes fingerprints when changing ROMs.

Might be different if you dirty flashed without wiping...

Perhaps you need to factory reset, then install again? According to TWRP docs, "A factory reset will also wipe sd-ext and android_secure if your device has those items."

Maybe fingerprints are in android_secure? Does herolte even have one?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rainer777:
Hi,

I switched to the latest build yesterday. Rom works fine.

But I cannot get write access to external SD card. For example the camera APP cannot store pictures in SD card.

Any hints for me?

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Timthedog:
[MENTION=5559607]Zuikkis[/MENTION], thanks for your reply!

Agreed. This issue should be more common if I'm right. And I've never deleted fingerprints when changing ROM, mostly cause I'm not used this function for apps before, and like I said LOS itself, like other ROM, seems to cope with it anyway.

And no, I 'm don't dirty flash when I' m started with LOS at 17.1 build 7. Actually I went all way from RR, via factory reset, via stock 8.1 to make sure that boot, modem etc. are up to date. The issue was there already then. Since build 7 I've dirty flash without any other problems.

Regarding the keystore area it's a interesting question! Since also Knox is kept there, will factory reset also reset a Knox trip? I don't know.

And if the areas are the same, we'll...

My next step is to rollback my system same way and see if fingerprint remains connected to old ROM. If this not helps I will do a new install from scratch at least system and the concerned apps.

S7 have a secure area, at least to keep Knox.... (and acc. to AOSP source).

[EDIT:] Now I've tested the rollback and it ends without any changes, there where no fp left at rr. And fp issue remains and my theory failed . Right now out of time so I have to leave issue at is, that is no fp in apps. I've also checked a bit more on another stock pie system and fp works, but not stable. Maybe I've to wait a few more updates..
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Mint Julep:
Is it only with camera app ? If so, change app. Try footej camera |works for me)

Try to use a files manager to access your sdcard.

Dude could you let me know how you generate your logs?

As I am having reboot, fingerprint and sound issues and I really like this ROM, but losing faith. Yesterday it rebooted three (3) times and also overnight with the boot overnight stuck on the boot animation.

Cheers
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Zuikkis:
There seems to be some magic in reboots. Sometimes after reboot the phone is very unstable, freezes randomly and apps crash. Then reboot again at it works perfectly. But sometimes can take 3-4 tries to get it stable.

Once it successfully boots in "stable" mode, it can go on for a week without booting.. I'm afraid to reboot it when it's working. :)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] crazydrive22:
Yes, of course.

First of all, you need a Computer/Laptop and a USB-Cable for Data.

Go to Settings on your S7 -> Developers Settings and activate Android Debugging (yes at the Popup).

You have to install ADB on your Computer (works for Windows and Linux).

If it's done open a command Window as an Administrator (just type cmd on search, klick right, open as Administrator) or open console on Linux.

Type the following to run adb and check the connection to your Device, what of course must be plugged in:

adb

(will show you a list of commands)

adb devices

(a Popup on your Device must be answered with yes)

If you can see the Device-Number in cmd, you're ready to start.

Finally, you need some commands to get your log.

I found a nice list of commands here:

https://wiki.lineageos.org/logcat.html

Sometimes it's a bit tricky to get adb working but there are a lot of sites with helpful informations.

Edit:

Try Moro Kernel, you can find on XDA.

Maybe it will fix your Problems with reboot.

Hello everyone,

It is my first time installing something on my Galaxy s7 edge phone and I would like to know if someone can tell me step by step to install it correctly. It seems that the steps to follow are implied and there are many threads and they confuse me. I don't want to be wrong. Could someone tell me how I should do it?

Thanks in advance,

Very good

I would like to know if someone has been able to use the browser application for a while and how the mobile has been carried, that is, how much battery has been consumed and if it has overheated during that time, it is very important to know, because I have installed the rom of lineages in another lower cell phones S5 and S4 and this has happened to them I would like to know the ones that have this rom installed, the mobile heats up and the battery discharges quickly.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Girkers:
Thanks for detailed post I really appreciate it.

I liked your idea of trying the new Kernel first as overnight my phone just died and did not even charge even though it was plugged in. Felt like a bit of a dufus though as it took me about three (3) hours to work out how to flash the Kernel trying all different kinds of things with fastboot trying to get it to work. Then could not believe how simple it was sideloading it through TWRP and it was all done and dusted after two (2) minutes.

Anyway I see how this Kernel goes and then try getting some logs if things go funny.

With this new build I was having issue with my speaker phone not working properly and I knew I had read earlier in the post about the mixer_paths file. So what I did was download the file and replace any Volume value 32 and under with 38 and any 60 with 62. I didn't touch any of the values that were already 100+.

Uploaded the file, reboot and test worked perfectly. File attached for everyone's reference

Please be aware that the value 38 is quite loud but I am old (47) and my ears are tired so be careful I have had to adjust the volumes down a bit, 32 is the recommended value.

Headset mic not working

Hi! Thanks for awesome work.

Everything seems to work well enough but I can't use my 3.5mm headset to chat with people. I can only talk to people with the phone next to my ear. I had the same problem a couple months ago when I tried this rom and I temporarily switched to LineageOS 16.0. Mic worked just fine on that one.

I tried copying the mixer_paths_0.xml file to /system/etc but the problem still persists.

Thanks in advance :)

In build 9, after a dead battery or reboot phone gets too hot and freezes after a point. After reboot it takes minutes for phone to become a useful situation. Background jobs and sync takes too much time after rebooting. During that syncs and app loadings after reboot (waiting without doing anything) phone again gets realy hot and can not be used.

Is there anyone else facing this kind of problems. I installed rom clean twice but, problems are still the same.

Edit:

Also, during that hot stage phone can not be charged. It losts battery during that stage while plugged in (\w samsung cable and adaptor). CPU temps hit 45-50C according to twrp.
