as a counter-question to the bug in the led notifications: does it work for someone?

Howdy!

After installing the latest stable, two things happened:

1) Lastpass started crashing when logging in with fingerprint. Password login works, and fingerprint works in other apps.

2) I can't connect to my car with bluetooth anymore, it complains about invalid PIN!

Given this, I thought I'd downgrade to the latest "non-stable" version, because it worked very well for me. I had TWRP backup from 8.8.2020, which I restored. But, the problems persisted! Lastpass still crashes and car bluetooth still doesn't work.

Is there anything else not affected by TWRP restore?

Edit: Looks like I might have been mistaken.. Downgrading Lastpass to previous version made it work. Also car firmware updated recently which might explain 2)...

Hi Ivan. Thank you for your work. I have done clean install. The rom is generally stable but although the camera has permission on sd card, it can't save to sd card. Secondly, is notification badges can be bigger? Have a nice day.

Hi thanks for the hard work, this version and the precedent have a bug, on my (SM-G930W8) the callers ''double hear'' themselves like an echo. I did not notice this problem in other roms (all the other rom have a batterry drain issue and unexpected reboots). Since it's my daily driver I'll probably have to switch to another rom until this issue is solved. Still it's an awesome rom. Thank you for your efforts.

Edit: JUst saw the echo problem was signaled before, sorry. Also the call recorder function creates blank audio files.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] geezahak:
Thank You

Fumbled my way through to getting a working install and am really pleased to now be free from all the Samsung and Google bloatware. Never installed gapps and am finding the barebones android experience an awesome reminder of what a pleasurable experience having a simple but effective device running latest android on older hardware can give. Thank you, for helping keep my perfectly healthy hardware survive in the wild a bit longer.

LineageOS 17.1 on Samsung Galaxy S7 rocks.

Am also really pleased to see this is still actively being worked on - have 20200603 build installed and am looking forward to trying 20200911 and see if i can learn a bit of how TWRP should work.

Found the install process for TWRP clunky af but am really glad i persevered.

Really hope more folks and more devs make more use of AOSP - it best thing Google are doing just now. They seem to be ruining mainstream android experience imo. eeesh those youtube on android updates ..... :eek:
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] tvfan1:
Same for me , when connecting through BT the phone doesn't ring+ there is a latency of about 7 sec till the other party can hear me

it's been like that since build 12..
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] windoofer:
Does that rom support volte?

Is there a option without root? i need to run software which dos not work with a rootet rom.

BTW: i tested the rom 2 weeks before, but the fingerprintsensor did not work with the setup...
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] geezahak:
It is a real shame there is no actual install guide for LineageOS 17.1 maintained by Ivan Meler or by anybody else on Github. I installed LineageOS 17.1 20200603 build without root and have broken Trust, SELinux as well as zero encryption and can not get android 10 desktop mode working with secondary display after installing Lawnchair launcher. The development of ~~windows~~ ooops android 10 desktop mode has been "dropped" by google, apparently. Which is a big let down for me. :(

Searching this thread for "install guide" gives https://xdaforums.com/search/thread/3980101?query=install guide which seems to indicate root and magisk are needed.

I tried using the "guide" at https://www.getdroidtips.com/lineage-os-17-samsung-galaxy-s7/ and it too suggests root is needed, if you follow the link for installing TWRP and rooting Samsung S7 but i also do not want root and found https://xdaforums.com/galaxy-s7/development/recovery-official-twrp-herolte-t3333770 shares info for both root and non root options for TWRP on Samsung Galaxy S7 but the outdated dm-verity and force encryption disabler zip caused my stock os to become unbootable whereas was bootable albeit without TWRP recovery before hand. lol Recent Google updates may cause need for root, as Google want to lock your device to your google account just to use Youtube app or youtube website on android. Which is massive bad move by them. i already looking at getting an iphone for first time in my life because of their recent antics. Even MS did not force live account with win 10 to lock device to live account.

So there is no concise guide. We all have to fumble or "hack" our way through and asking about such "low quality" things such as Install Guides simply seem to get ignored here.

Not sure where non developers wanting to use LineageOS 17.1 builds could go to discuss all these things. Appreciate XDA forums are really intended for developers.

Not sure if we could just use rooted device to install LineageOS 17.01 and then revert back to non root and re lock bootloader. Sounds like a TWRP and/or Odin feature request.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] girtsn:
default clean install of this rom (and Lineage default in general) is non-rooted

flashing Magisk is optionally added to get root

nevertheless, some software wrongly reports custom roms as "rooted"

in some cases, Magisk + configuring hide works better on custom roms than not noroot

there is really no magic, don't want root access don't install Magisk
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] chrisrevoltes:
Maybe because its Ivans opinion, that someone who wants to flash a custom rom, can at least do some minimal research. For your info: It's the same way for the S7 as for most of the other Samsung phones (and others). Just 3 weeks ago I postet my steps in this post.

In generall you're right that it would be more convenient, but calling it a real shame is very disrespectful.

Why did't you flash the newest STABLE version (20200811 or newer)? Maybe that fixes your problems.

In addition to [MENTION=246790]girtsn[/MENTION]s search results, here an older but accurate video I found for you: https://www.youtube.com/watch?v=a8-ISL3gM_s

That google droped it is sad, but its not the blame of LOS defs. Btw, I didn't knew that there is such a mode in LOS17.1. But if you explain what you have tried, I would like to try it myself.

Odin is not even closed source, its presumably not even official released for the public. Heimdall is its open source alternative. (source here)

Im pretty sure that TWRP wont give an option for a locked TWRP.

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] geezahak:
[MENTION=8406503]chrisrevoltes[/MENTION] Sorry you feel i was being disrespctful when saying "really sad", i just really do think it really sad that so many Samsung devices come to an early EoL because of greedy companies like Google and Samsung. It thanks to devs like Ivan Meler and LineageOS that some continue to be used. i was really just trying to say more owners of such devices that have reached end of life support officialy can benefit from projects like Ivan Melers LineageOS 17.1 if there were better installation guides provided. There are many guides but they just seem to be hard to follow, somehow. i had to rely on many guides to get LineageOS installed, but it a broken install. So still looking for the guide that works.

https://www.xda-developers.com/make-android-10-desktop-mode-useful/ clearly explains google dropped development of desktop mode in android 10 which would of meant desktop mode was native to android

For android devices that do not support DisplayPort AltMode I use a docking station that uses DisplayPort Presenter apk to allow usb secondary display and adds huge I/O expansion to any android device

https://www.raidsonic.de/products/adapter_multidocking/multi_docking/index_en.php?we_objectID=4993

That together with Sentio desktop app makes for a fairly cool desktop mode and am sure Sentio desktop app is the real proof of concept behind Launchair. Sentio desktop app has not seen any updates since android 10 beta was released ...

The video at https://www.youtube.com/watch?v=a8-ISL3gM_s really was a great help in making sense of the written tutorials i referred to earlier. It also proves root or magidisk are not needed for lineageOS 17.1 [MENTION=11098205]windoofer[/MENTION]
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Wattsensi:
It is indeed really sad, it all creates unnecessary e-waste in developing countries, also even if its old my S7 is still a powerhouse that deserves to be up to date. All in the name of making more money, this short-sighted mindset is leading us to the destruction of our planet. We could instead recycle old motherboards, display panels and make repairable phones but companies are greedy and CHOOSE to waste precious rare earths that usually involve slavery to mine.

We're saying no to this wasteful attitude.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Kernle 32DLL:
So, finally made the jump to 17.1 last week. Everything is dandy, except two problems:

1. fingerprint sensor is only working half-ish. I can use it to unlock the phone, but not in apps (e.g. for Keepass, or banking apps)

2. bluetooth range is awful. For my headset, I literally have to hold my phone in front of my face. Putting it in a case (or my pockets) practically means instant signal dropout (on stock all is fine)

I made a clean flash, installing a full stock package beforehand. Point 2 was already a problem with 16 for me, hence the clean flash to rule out any problem in that regard

Hello,

I have an issue after installing this custom rom (or any other one): I have no service. No SMS, no call, no data.

I tried :

1) reinstallation of last stock rom with ODIN. everything is OK

2) flash last TWRP version with ODIN

3) installation of LineageOS with TWRP: still not OK

4) after modem flash (coming from last stock rom in 1)) with ODIN: still not OK

thanks !

Quick newbie question...Do I have to wipe all data and reinstall all my apps each time a new security patch releases? If not, how do I keep all my data while updating?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] shaq1907:
No you don't need to wipe for updates. You can just install new roms via TWRP without any wipe. Just installing way.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Wattsensi:
If you need to flash your modem to make it work then make sure it works on stock ROM before trying out AOSP, perhaps you flashed the wrong modem image. I have full radio capabilities on AOSP.

Also did you unlock your bootloader (on stock ROM, enable developer options and enable OEM unlock in developer options. Your bootloader is now unlocked)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] ch0tax:
I, too, have bluetooth range/signal strength issues. Clean install, tested two pair of bluetooth headphones, music transmission is cut off completely whenever I block the headphone's bt receiver with my hand at 1m distance between phone and headphones.

Both headphones work perfectly fine on other phones.

Otherwise awesome rom, thanks for keeping our S7's alive! :)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Arbre4:
maybe it wasn't clear. I did what I wrote (1,2,3,4) in that order. I used the same modem image on stock and lineageOS. and yes, developer option and OEM unlock is enabled.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Wattsensi:
Try checking your IMEI. If it returns an anomalous number, you could have the infamous EFS problem. Try mounting /efs in TWRP (just mount and unmount it) If you get an error, restore the EFS backup that I REALLY HOPE you made. If you don't get an error then backup it immediately if you haven't
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Arbre4:
héhéhé... Nop, no EFS backup here sir. But my phone is currently working perfectly with the stock rom. I should do this EFS backup :D
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Wattsensi:
Good to hear, if your modem works with the stock ROM then you should just flash LineageOS and it will work. Is your phone dual SIM? I think some AOSP ROMs have issues supporting dual SIM. SM-G930FD is a dual sim Exynos S7
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Kernle 32DLL:
Can confirm both problems on the 2020-09-11 build with my regular G930F, too. As for the echo: It only happens when using the phone directly. Using a headset there is no echo.

bad reception on non LTE cells

Hello all,

After updating from LOS 16 to LOS 17 I have encountered problems with phone call quality. On idle the phone has good reception on an LTE cell even with mobile data off but once a call is made does not matter if incoming or outgoing the phone switches to other non LTE cells and have miserable reception on them. Barely any reception, the call is very low quality and the voice transition is intermittent on both sides because of this. I have updated the modem and bootloader to the most recent I found, but the thing did not improve. Also I dirty flashed from LOS 16 to 17.1. Can try to clean flash but I do not know if there would be any improvement, otherwise the OS is stable. Also the phone is rooted using Magisk. Could someone give an advice how to improve the call quality? Does anyone have the same problem?

Thanks

I have a noob question, so I did fresh install LOS17.1, wipe everything and all, and flashed TWRP 3.4.x.x all works fine... now I did encrypt my phone, and I know that TWRP 3.4.x.x doesn't support back-end encryption, to update the current OS to the latest patch from this month, do I really need a TWRP that support encryption? or can just flash the OS via TWRP since I don't think it doesn't need to access /data? any idea if that flashing would work?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Ivan_Meler:
Also some info about android 11/R build, Ril now works so does camera and everything else i tested excluding bluetooth and adb

Bluetooth should be easy enough to fix as it will require rebase of custom bluetooth implementation on top of new hal (Not too hard), as for adb (other usb modes do work) google removed legacy handling of FunctionFS, So that wil lrequire some kernel changes, After that is handled first builds should be out
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Arbre4:
It's not a dual SIM.

Try a "smaller" GApps package, like pico.

If you need some missing apps then, you can load them from PlayStore.

Hi, but I get the browser, the emailer and the music player even if I do not not have any gapps package installed. My question is if I can remove these default applications that I do not use (and, if possible, then how). Thanks in advance for any suggestions!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] downhere:
I see. You're right, it's not GApps related.

I use the Start Screen options to hide those apps.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Mint Julep:
Everything is a file !

You can use a rooted file explorer (I use Mixplorer ), go in the root partition, ans delete directly the apps you don't want.

Be carefull : some can be hard to get back. If your not sure, just change the extension of the apk file.

Moreover, be sure to install replacement app before you get rid of stock apps. Because if you delete your internet browser, your sms app, or your keyboard before getting a new one, you'll have trouble :)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Hemuli:
I don't know what you want to achieve by removing them, but there are even more ways to do it than already mentioned.

If you want to just hide them, you could simply disable them from the settings. Or if you want to go full hc, you could build the rom yourself without the apps.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Ivan_Meler:
Another quick progress update on R/11 builds, i resolved adb issues, this leaves bluetooth on non working list but while testing rom i noticed that hwc can randomly crash when switching orientation or going full screen. This will have to be looked into a bit further before release but once those 2 issues are solved 11 builds should be out and stability wise they should match current Q/10 builds
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] sailorpito:
Just install Magisk Debloater module, it does what you want and it's easier to recover uninstalled apps in case you need it

Phone connection dropping

Hi all,

First of all, thank you very much Ivan for keeping the S7 alive and updated. It’s much appreciated.

Your latest version of LOS is pretty much perfect except for a few things which others have already mentioned.

I seem to be having a problem that I can’t find anyone else having, tho.

Whenever I make a call or receive one, the connection just drops between 5 and 20 seconds.

As you can imagine, this pretty much renders my phone useless as… a phone.

I’ve tried the two APN’s that my provider offers (T-Mobile NL) but it makes no difference.

Phone calls are just a no-go for me with the 11.09.2020 build.

I was thinking it may be a problem with the modem firmware and tried to flash the latest official version with Odin for my region, but that failed.

Not sure what else I can try except going back to LOS version 16, which worked perfectly.

Just wanted the latest security updates so I gave this version a go.

Hope someone can shed a light on this.

I’d post a log but so far I haven’t been able to get adb working on my pc. Another conundrum.

-edit-

I had another go at flashing the official Samsung modem firmware (G930FXXU8ETF2_G930FDNX8ETE1_TNL in my case) with a newer version of Odin https://xdaforums.com/android/software/patched-odin-3-13-1-t3762572) and this seems to have fixed the call dropping to a degree. Made two calls to test, first one dropped after about 3 minutes but the second one lasted for over 10 minutes. Good enough for now.

The person I called did mention the echo, but it was less obvious than before I flashed the InCallEchoFix.zip someone posted here. Thanks for that too, can't remember your name.

Another issue I have is battery drain.

Fully charged when I go to bed, my phone will have lost approximately 30% of it's charge when I get out of bed.

That's in 8 hours time while the phone is completely idle.

On LOS 16 it would lose less than half that.

I've looked at the battery stats in Android and all seems normal, no anomalies reported.

The 3c Battery Manager app also doesn't show anything out of the ordinary.

At last I checked with 3c System Tuner's task manager and that didn't show me anything to worry about either.

So what could be causing this absurd drain? Is anyone else experiencing the same thing?
