[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] 2o324ohfw:
My review - Very first custom ROM experience coming from stock S7 (Canadian W8). I hope I am following the forum rules, but I don't know how to tell the difference between base issues and the S7 specifics, and don't know how to find known issues.

Notes:

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

The good

- Hats off to the developer - 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. Often when I boot, I get a message that the SD card needs to be taken out and put back in, but I learned to ignore the message.

- I had concerns about the camera from reviews and comments, but those are unfounded at it works very well. I had some storage problem where the camera complained it could not access SD, but I just changed the setting and all is well.

- Set up Google Pay.

- Android Auto is much more reliable.

- No problem casting (tried youtube).

- Battery life is improved.

Issues:

- Current major problem is the call volume, with or without earphones. The volume is insanely loud, and nothing I tried can change it. No controls seem to be available. I tried volume contolling apps to no avail.

- My Gear S2 watch cannot work. I followed the instructions on post t3743138 but Samsung Gear still refuses to open.

Minor things:

- First boot after install kept going for an hour before I hard reset, then it booted up quickly.

- Had intermittent times when wi-fi would turn off for about a minute then come back on, when I was downloading my apps, so under heavy usage.

- The system freezes once day, sometimes even while vibrating. VolUp-Power-Home reboots out of that and I am quickly back in business.

Fingerprint functioning :

Lockscreen. Worked all time. Stable

Google pay. Start working now.

Revolut. Start working now.

Not functioning :

PayPal. Hangs at setup. Finds fingerprint but stops before next step. Haven't checked log.

Keypass2android. Hangs at setup. Finds fingerprint but returns acc to log with exception code 3, system id and fingerprint mismatch.

Keypass Dx. Seems to setup correct but at next start says not setup. Haven't checked log.

Two local bank ID apps. Both says not supported without exception. I think that this is correct, android 10 isn't implemented yet. Haven't checked log.

There are a couple of more apps to test but haven't the time right now.

Anyway since Revolut works this issue must be connected to app functions. All of them work with pie stock. So right now I'm looking forward to app updates...

Thank you, the roms is awesome and I use it daily, my S7 is awesome now!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Ivan_Meler:
So here is a progress update, Fingerprint issues have been completely patched, Mobicore and fingerprint implementation has been completely reworked which was a mess, In other news GPS has also been fixed which involved reworking whole RIL stack and im testing builkd with those fixes at the moment there are also a lot smaller fixes in this build i will post in changelog once new build is up in few days hopefully if everything goes alright

I am looking forward to try your ROM since last year but I will wait for OTA update support for your ROM. Do you have any plan to add this feature to LineageOS 17 soon?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] cgirerd:
Thank you so much for your work Ivan!! I switched from an s7 to a redmi note 4 two years ago because support was not that good, but I'm back to my s7 now. Really like this phone!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Lailouezzz:
THAAAANK YOU !

You have offered a new life for my S7 :).

A list of my issue after 2 days :

- Quickstep error (when google play service for ar is in recent application) so I can see my recent app

- Restart randomly with GPS inactive (when downloading in playstore or other)

- Speaker error logcat (I heard my speaker sizzling every error audio_hw_primary (invalid argument)) : SEE SCREENSHOT

ww.noelshack.com/2019-44-6-1572721691-screenshot-20191102-200355-terminal-emulator.png (add w, it's my first post)

- In option Display->Style->Dark Mode (error when changing value)

- LiveDisplay not working for me

- SnapChat issue when playing video or vocal (sometimes not work ? SnapChat bug or Android ?)

- Youtube issue when playing video (sometimes I have infinite loading)

- In TWRP I see a strange things : the system folder is located in /system/system ? WTF ? It's normal ? (the system partition is used for the root path, I can't see system in proc/mounts ? That's normal ? Go see that in File Manager (In TWRP Recorvery)) :

1- Mount system in TWRP

2- Go Advenced->File Manager

3- Go /system and see the content

4- Go /system/system and see the content

- All other issue already quoted

Simple curiosity, Is it possible to compile yourself LineageOS 17 for S7 with your source ?

Sorry for my english I'm french.

Nice, I will test the ROM today

Can't seem to get past the initial setup. Getting an error that "Android Setup keeps stopping"
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] kimush:
Try booting to TWRP, mounting System and deleting the /system/system/product/priv-app/Provision folder.

I haven't tried it, just a guess.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] VGMC0001:
I do not see a "Provision" folder in the Priv-app folder.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] kimush:
Maybe use a different gaapps package. Try 'gaapps beta'.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] KevMetal:
delete the actual setup apk from priv apks

well delete ..better just copy it to sd

then delete ..then see ..if it doesnt help put it back

by provision he meant to say android provisioning ..

same process ..first try one ..then the other ...then both ...but keep a copy to put back on sd unless you wanna just dirty flash rom over after delete and no success

---------- Post added at 04:15 PM ---------- Previous post was at 04:14 PM ----------

before doing that try to boot without gapps ...if it doesnt startup without gapps another gapps package wont make a difference
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] VGMC0001:
So first I deleted the setup.apk. It booted without error but was quite buggy. Home button wasn't working and some random reboots.

So I wiped and reinstalled without Gapps. It booted without errors again.

Then I installed Gapps. Still looking good.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] KevMetal:
what gapps are you trying
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] VGMC0001:
BiTGApps
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] dlcarvalho:
Unfortunately both build 1 and build 2 doesn't work on my SM-G930F. I have wiped system, cache and dalvic. They stuck in lineage boot logo. I have wait around 30 minutes and nothing (with and without bitgaps)...

Thanks [MENTION=4610599]Ivan_Meler[/MENTION] for the efforts.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] mammenj:
The second build is so far awesome, clean installed it so no issues in installation.

I am using s7 as backup, so not tested fully but seems lot less buggy. I really want to come to S7 after this build.

Thanks [MENTION=219320]Ivan[/MENTION] :good:

BTW, the dark mode is not working for me.

Any feedback on call quality?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Gargoyles:
Sometimes, I had to wipe internal storage too, and that did the trick.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] carlos964:
I too had the same problem. I have formatted and installed build 2. It is better to make backups first
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] hamidreza.r:
build2:

bugs:

1- Camera didn't work (can not connect to camera error)

2- when i touch the screen , back and another one button Led is up. its not good

3- brightness level didn't show true percent (in middle show 35%)

4-call app so buggy

btw thank you.

Again, please attach logcat to help Ivan solving the issues
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Timthedog:
[MENTION=9662044]rdelmont[/MENTION], by some means (I'm not qualified? ) I cannot add logs as attachment to my messages which is the fast and simple way to give Ivan this information.

I certainly know that debug based on just words from users isn't the easiest task. But hopefully the lifting of the fingerprint issue at least can help other junior members to test or avoid problems.

So I'm sorry, but as long as this forum give me problems not connected to S7 LOS there will be no logs.

Best
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Timthedog:
Ok, since this discussion seems to raise an interest for the fingerprint issue let's do it. I've got the old log from KP2A Authorization failure that I try to attach , but failed due to forum rules. Sorry it's build 9 but I do not have time to do it better right now.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Darkstriker:
Thanks for providing the info on which apps still have issues. You just saved me an hour trying to test it, since KP2A working is absolutely essential to me.

Regarding you blaming the apps, I don't think that is correct. I have an Android 10 device and so do some of my friends and KP2A works just fine with their FPs. Also Android 10 is almost a year old at this point, so I wouldn't hold must breath for an app update that helps fix these things.

Hello, good job wit the rom. it´s have some problem with the battery, it wears out very fast . Sometimes restart alone. The app WhatsApp have problem with de camera. Two times, I´ve do forced restart, the screen froze. Sorry for my english.

Problem with proximity sensor

Hi,

it seems the proximity sensor is not working correctly with this ROM - that's at least what I observed, coming from the LOS 16 from ivan for the Galaxy S7. After updating (with fresh install of course) to LOS 17.1, the proximity sensor is no more working (always reports proximity = 0.0cm). I found this out, because the display is switching off immediately when a phone call is started/incoming, and there is no chance to switch it on again, but the other party finishing the phone call, or rebooting the phone. Looking at the AOSP phone sources, this behavior can be confirmed when proximity sensor is not working/stuck at 0.

Anyone else observing this problem? Is this a ROM issue? Any workarounds - phone calls are really awkward with this behaviour?

Thanks blei
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Zuikkis:
Try pressing the power button.. On my phone, display is also switched off, but power button wakes it.

I'm not sure if there is some config setting, "power button wakes display"
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] blei:
Thanks for your tip, but doesn't help, power butten does not switch-on display - that's what makes calls so awkward. Also found no setting "power button wakes display" in the ROM - the only one I found was "volume button to accept a call" - but this is disabled (on purpose). But I understand, you have the same issue with this ROM?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] mubaidr:
I have the same issue. I thought it was the hardware issue. :s
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Zuikkis:
I used Sensor Test app from Play store. Proximity sensor is working, although it only seems to have two states: 0cm and 8cm.

For me the only problem is that after the call I have to wake the display with power or home button. Not a big deal.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tvfan1:
I woke up this morning and the phone was dead, i had to put it into recovery mode to get it back. this is in addition to daily reboots that are more frequent than in previous builds. I have submitted logs for the last 2 boots I had. thanks in advance for looking into this (+ it'll be also great if there is a fix for the BT issue that makes it really hard to use the phone in a car environment)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] blei:
The behavior you described, was what I observed with LOS16. But now with LOS 17.1 it's as described even worse. Proximity Sensor built in my S7 is a AMS TMD4904. [MENTION=4610599]Ivan_Meler[/MENTION]: This seems to be an issue - can you check on that - if you need further logs let me know.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] girtsn:
June update (build 10)

0. wifi is extremely unstable, each day it goes to mobile connection and have to restart to get Wifi back

1. volume low on incoming calls, vibration on call too weak

2. random reboots quite often, multiple times per day - usually just starting a new application perhaps to do with Magisk

3. Chrome often choking up when loading resource intensive pages - seems fixed, don't have this anymore
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Roberto W.:
i am using build 10 about 12 days now and i have a couple of errors and missbehavoirs, but till now no crash or reboots.

my setup:

moro kernel

no gapps, i am using nanodroid + playstore

magisk

edxposed

major issues:

-low volume

-wlan disconnects on weak networks

-stock mail app does not update incomming mails automaticly

-display stays on randomly, no standby

most of the issues produce log entries with error messages. i will try to catch them.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
I doubt Ivan will support for issues if you are using third-parties kernels... In the OP you'll find the related disclaimers
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Roberto W.:
the major issues apear on stock kernel too, as i see here.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] downhere:
[Build 10]

Had reboot again. Log is attached.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Timthedog:
Thanks! Valuable information. I got only a stock Pie to compare with so it's really interesting to read that at least KP2A fingerprint works on stock 10. Which hw do you use, is it Samsung as well?

Ask because FP includes also a hw part. So could it be a hw error? I mean of course LOS 10 combined with s7 hw. FP works all right on my s7 hw on stock oreo. My Pie is not a Samsung but here works FP as well.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Darkstriker:
It works on my Mi 10 and Galaxy Note10 as well as my gfs Mi9. I'm positive that this is a driver-related issue on the S7 with AOSP Android 10 or the Note-based Android 9 builds.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Helmy José:
I dont have any problem with that. Works perfectly
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Timthedog:
It looks like you have been testing more than me on this issue. Nice! Well it's seems that we're tracking this issue down. As soon as I am able I will submit logs on my part to help Ivan close this [MENTION=2097072]Darkstriker[/MENTION], do you have the ability to provide some logs to help Ivan? I'm right now really short of time....
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Darkstriker:
I may in the near future. For now my S7 is my daily driver and I simply need my FP to work. I'm just grateful it is finally an acknowledged issue and that you prevented me from having to test it myself only to find out it doesn't work yet.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Zuikkis:
What is this "KP2A" you are talking about? KeePass? Is it easy to try if it works?

Fingerprint is working in all apps for me. Google Pay, Lastpass, bank apps..
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chrisnice906:
This been fixed yet?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] ibrahimqureshae:
Hey guys , is there any way to change my csc? I don't have call recording on my phone.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] padraigdoran:
Just install Call Recorder by Skvalex. It should work with default settings but try ROOT MODE recording if you need to.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Timthedog:
[MENTION=5559607]Zuikkis[/MENTION], it's keypass2android I'm referring to. For me I get an exception when I try to setup FP in settings. The procedure start all right, but it ends with code - 3, which acc to source means system ID and fingerprint mismatch.

So it's really easy to test for just this app. But right now I believe that this issue is driver related. Does it works for you on s7 /Los 17.1? If so I'm back in that this is a problem for me and my phone setup. So will you please test and confirm if it works correctly for you?

Hey!

I'm using the actual build 20200603.174538 on my SM-G930F

My phone crashes and reboot round about 10 times per day. Phoning via GSM is very quiet.

What can I do?

Greetings

Maeck
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Roberto W.:
it is a clear installation without any special software? i have g930f without crashes and reboots.

for better volumes u can try a modified mixer file mentioned some pages before.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] downhere:
What do you mean by "special software"?

Suffering from random reboots too, provided some log files already too, but still clueless about the cause.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tvfan1:
Same here- running on clean installation of the rom, not rooted, no other modifications (still using the original mixer), very frequent boots/ crashes and inability to connect to BT- already sent logs
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Zuikkis:
Hi! I tested and it didn't work for me either.

But this must be something in the app itself. Fingerprint is working fine in other apps, like Lastpass and Google Pay.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] maeck:
Yes, running on clean installation of the rom, not rooted, no other modifications. Didn't try the modified mixer, cause I thought it was changed in the last build and the problems should be solved - but it's not.

Also inability to connect to Bluetooth devices.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tvfan1:
+1 exactly the same behavior on my device
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Roberto W.:
for those who have reboots and crashes...can u try the moro kernel to see what happens? of course that is not the solution at all
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] downhere:
Bluetooth (headphones) is working without any issues here. But still having random reboots.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tvfan1:
my BT issues are with my inability to connect it to the car audio (there is a 8 sec. silence before the other side hears me..)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] :
Are there non-LOS based custom ROM's not having these issues at the moment.

Switched to LOS some weeks ago but is not working for me.

BT, reboots, low earpiece volume..... to much issues for a daily driver I am using for my work....
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
For daily drivers best to use LOS 16.0 which is stable. LOS 17 is still beta.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Timthedog:
Thanks for testing this [MENTION=5559607]Zuikkis[/MENTION]! But as [MENTION=2097072]Darkstriker[/MENTION] already have pointed out this apps works correct on newer Samsung devices (as well as other brands) with stock Android 10. His conclusion, which also is mine right now, is that 10 sw works for the apps and the apps behaves correct as well, but the glue between Android 10 and s7 hw, the driver for FP, one way or another fails. Of course I've already tested this apps on s7 latest stock, oreo, where they worked as expected.

So stock 10 is ok, the apps is ok... LOS 17.1 is in the middle to implement new Android versions on old devices /hw. So here we stands for the moment.

BR
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Darkstriker:
Those work because they don't actually encrypt anything. There is no need because Google and Lastpass both have direct access to all your data. They just verify that it's you using the device.

Keepass2Android on the other hand uses the Android security system to encrypt your password (or partial password) using the FP. That function is broken in this ROM for now.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] :
With the issues I have, I think the label 'beta' could better be 'early beta' or 'alpha'. But back to my question, I mean an AOSP / CAF based Q-rom, just because of the benefits of system wide black theming, intelligent battery management etc...

When there isn't, I will switch back to LOS16.

Edit;

Switched back to LOS16 yesterday which seems to solve all my issues.

As also that build seems still to get updated every month by the great dev [MENTION=4610599]Ivan_Meler[/MENTION], this is my daily driver now for the S7.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Zuikkis:
I installed Moro kernel yesterday, not a single reboot after that.. So it might be worth a try. Also some hint to [MENTION=4610599]Ivan_Meler[/MENTION] that the spontaneous reboots are probably kernel related.

Moro kernel available from here:

https://xdaforums.com/s7-edge/development/23-04-17-morokernel-1-6-g93xf-t3594754/page139

The topic is "hidden" in s7 edge forum, but the kernel is also for s7 flat.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tvfan1:
Thanks for the info

I am going to take it for a spin as the boots/ freezes are too often. I have 5 noob questions:

1. How do I flash it ? -TWRP? ( Is it possible to flash it on top of the current kernel?

2. Root- my phone is not rooted and I don't want to root it- can I still flash it w/o root and also keeping my phone unrooted?

3. how can I switch back (in case I need to)?

4. will flashing a new build from Ivan is going to revert me to the default kernel or is it a permanent change regardless of the rom I'm flashing

5. Any chances that flashing a new kernel will help with the volume/ BT issues I'm having?

Thanks in advance
