Thanks Ivan!! Downloading now. Is HWComposer working in this build?

Looking forward to seeing if the BT changes improves the call quality through my head unit. It worked, just not very well.

[Edit]Downloaded and dirty-flashed! So far so good. UI seems decidedly snappier, so I'm assuming HWComposer is working - although maybe that's just wishful thinking.

I would like to know if HWC is working too because I would upgrade from Los 15.1 if so.

can someone dirty flash from 15.1 to 16 ? I guess as gapps versions will be different.. i think the upgrade may not be possible.. anyone?

Don't dirty flash. Just do a Clean wipe and install

Ivan, you're really doing miracles. HWC is an issue for me, so I will have to wait a bit longer, but it is really outstanding work, well done! And thank you for your efforts.

Holy ****, that was quick! I wasn't expecting another update for this ROM for months! Fantastic job Ivan, I am really blown away by how well this ROM is turning out

oh yeah! last build I had issue (bug) with pressing on attachment in messaging and app locking/freezing NOW seems to be fixed as I was using it today with good success rate so tried 4 times and had app lock once so yaaaa! Have not tested the crackling sound during video as had last time but loving this build!!!

Hi!

Thank you, rdelmont and sharkcow. I first tested to disable "tap to wake up" in display settings > advanced but it did not work, it still autoplayed music in my pocket. But when I set "the skip to next/previous song with volume button feature. That has caused me quite some embarassment in the past... you can find the setting under system|keys", the problem was solved. Thanks again Sharkcow.

I noticed that my Samsung S7 (stock Android 8.0) provides much better sound quality than my Xiaomi Mi 8 with the latest MIUI11 by xiaomi.eu. Will I retain that level of quality with LOS16?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
There should not be any proprietary driver in AOSP roms, audio ones as well, so playback quality might differ from stock roms. Stated that, in my opinion playback on this rom is pretty good, both on speaker and headset, without any further mod, which you could eventually try (like magisk audio modules, for instance)

Two days of continuous usage of build 25. Rock solid to me... Did calls, sms, photos, whatsapp, surfing, emails/calendar, news reading, you tube and some weird networking stuff (rooted busybox + terminal emulator + hotspot). 0 issues to me, big kudos to Ivan :good:
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] elnicatuani05:
Has anyone had issues with WiFi during initial setup? Previous build wouldn't let me connect to my home WiFi network. I'll definitely try this new build, though I'd like some advice about what to do in case I experience same problem.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] HenryLolsen:
I installed the latest build today, the process went relatively smoothly.

However, multicore benchmarks are much worse (only 800 points in geekbench 5). CPU-Z shows that two of the M1 cores are deactivated... I guess that is not normal.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
That's normal, last two cores are used only when extra CPU power is needed. Just checked out on mine, right after launching CPU-Z all 8 cores are up on MHz for about 1 second, then core 7 and 8 go disable. All fine.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] HenryLolsen:
yeah, I noticed.

But it remains a mystery then, why the multi core scores are that low. Could you just test your device, so we can figure if it is ROM or device related?

In Geekbench 5 you should get around 350 for single core and roughly 1200 for multi. The respective values for Geekbench 4 are 1900 single und 5800 multi. My single core scores are reasonable, however the multi core ones are atrocious (850 and 3800). Therefore I wondered if it might be related to disabled CPU cores.

Maybe I should test a different kernel.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] foudroyant:
I took the plunge and installed this, for the trivial reason that as a "feature" of stock Samsung the notification doesn't blink for new text messages if the messaging app is left open on top. Overall everything works pretty well EXCEPT for the exact function I was looking for which is made much worse. For some reason the LOS Messaging app crashes on me whenever I click the attachment paperclip, it says close or wait, if I say close it hiccups and reopens, click paperclip again and this time it closes for real. Anyway I wanted to use the Google Messages app--but with that and seemingly all other messaging apps the notification light simply doesn't work for some unknown reason. Specifically, it usually will flash/light up for a couple seconds and then mysteriously stop, and I've tried every possible setting. Yet the notification light seems to work fine with all other apps I tried, with battery/charging, and it seemed to work with the Messaging app. I saw a thread where they patched Lineage OS 16 notification light for SMS with this behavior and it seems maybe that code was somehow narrow or inelegant, only working for Messaging not other SMS apps. Any way to get the darned blinky working for messages? Maybe I could buy for a few bucks a standalone app that will Just Work for this one thing I'm obsessed about
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
On mine, Geekbench 5 gives 380/818. Scrolling down the results, you have the overall ones for device type and I see that for S7 se have 267/711; guess it's aligned though
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] HenryLolsen:
No, the S7 Exynos should have 350+/1200+, the Snapdragon S7 is much worse (2xx/7xx).

I start to believe it might be related to battery status. Tomorrow morning, with 85+% battery, I scored 380/1200, now with roughly 55% left, it is back to 350/800. I think on Stock Android 8.0. this did not happen, but I am not entirely sure.

I'll continue testing...

edit: hmm, no, it is not the battery, even with 90% it just scored 800 multi core again...something is wrong there.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Digger_m:
Are there any fixes for the wi-fi disconnecting. As its ongoing not just when the phone sleep but when it's in use like when an a Facebook call or using internet radio. Would really appreciate any help on this WiFi disconnecting issue. Dose the los17 have this issue?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Matty1993:
Last 2 cores are set to disabled by default unless the cpu comes under stress and requires the extra oommpf only then are they activated this is to save power as having the extra 2 running while low_memory background apps and services are running etc etc etc would be just extra uneeded drain on the battery, try opening a decent sized game like PUBG then check your scores again while its still running in the background, could also be some memory_saving method somewhere or properties to save the cores from idling to high whilst not under load also anyways

Fantastic work to ivan as always havent had a chance to test latest build but will sometime this week on my tester :D

I installed the 20200218 build yesterday and things appear to be fine except for the network connectivity which only goes as far as H+, not LTE. Previous build that I had installed, 20200119 had LTE. Any idea ?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] downhere:
Have you checked preferred network settings?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] xoy74:
Of course, it's set to LTE (recommended). I've also tried to reset the network/wifi/bt settings. In case it matters, the model is SM-G930W8 on the Rogers network in Canada.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rdelmont:
I'd suggest to check the access point names under settings > networks > mobile networks > advanced. Sometimes you get automatic settings from your carrier which are not correct (It happens most of the times with so-called virtual providers, from which you get the settings from the underlay carrier)
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] nostromo12:
In the past I reported random crashes. Smart lock did not work properly, especially the trusted locations did not work at all. In that case the memory of the google services has to be deleted completely. Smart lock and android auto settings must be redone.

There was one reboot only during the last two weeks and android auto connecting is fast as lighting! :cool:

Thanks so much for keeping this device alive and up-to-date. Is there any chance you will add wireguard support to this or your LOS 17 kernel ? I was using the Reflux kernel to have this support, but it seems its no longer being maintained....
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] OllyFunkster:
Hallo! Firstly thank you for this ROM, everything I rely on seems to work so far.

Colour rendering in the night-time part of LiveDisplay is hilariously bad... I am sure this is generally in LineageOS rather than just this build, but a LOS 16 build for the S4 Mini (here) has Night Light instead of the two colour sliders, and does a really nice job of keeping colour looking good when in the night mode. What determines which style of colour adjustment is present in a build, and is there any possibility to switch it to Night Light in this build? Perhaps by editing some configuration on my device?

Thanks again.

EDIT to add: actually I don't think the bad night colour is the fault of the part that's setting the colour temperature - if you use the "Colour calibration" menu to e.g. turn the Red channel pretty much to zero, all the white stuff goes cyan but any pixel that's actually got a red hue to start with stays bright red!

Is this colour balance done in hardware or software?

How to enable SE-Linux?

Hi,

First, thanks a lot for this image.

In your build SE-Linux is disabled / permissive. Is there a way to enable it as additional layer of security?

The official linageos 16 for i9505 / galaxy s4 has SE-Linux set to enforced, so I would say it is not a lineageOS issue.

Thanks, Butch

Hi,

First thanks for your work on this ROM. I have two questions for Ivan_Meler:

How can I build your ROM myself? What special bits for it do I need to know compared to the instructions from https://wiki.lineageos.org/devices/herolte/build?

Do you plan to make your builds official? Is there anything blocking? Can we help there?

Hi [MENTION=4610599]Ivan_Meler[/MENTION]

To make the story short ;) : Since Microsoft decided to stop support for its phones, and the "worst", WhatsApp blocked the functioning of its app on my beloved L950 this past January, I felt a little bit "orphan" :crying:. Decided then it was time to go to Android, with no Google stuff if possible. After some reading... thought that LineageOS could be what I was looking for. Found a refurbished S7, very good shape. Then discovered that there was no more official support... And then discovered the XDA forum and your ROM : its great! Flashed it with no Gapp/OpenG and it suits my needs for the moment. Many thanks Ivan ! And thanks to all the people with their explanations/advices along the 200+ pages in this thread ;)

You know what? I'm happy :)

Stuck in startup animation

Hi at all,

I started my device in Download Mode and I restarted it. Now I'm stucking in startup amination. Is there a way to get it work again. I don't want to reflash it because it is in productive usage.

Could I delete the cache or other temp files to get it start?

I can't know that a simple restart will crush LineageOS.

Thanks for your help!

Have you allowed TWRP to install TWRP system app?

If yes, go back & disallow, as this will definitely block LOS from booting (as all other system apps which come without proper permissions)

Thank you! Your advice solved this issue!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Ivan_Meler:
new build is up with quite a few changes

- Merged XXU5ESD2 kernel changes

- Merged XXS6ESI4 kernel changes

- Fixed kernel side security issues related to binder

- Merged march security update

- Synced with LOS source

Im also working on a complete rebase which takes some time but should bring more stable user experience (Keep in mind im doing this in my free time)

That should help resolve any stability issues that might be present

Also big thanks to everyone who supported this project as that helps me with covering build server cost and coffee cost

[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rho-bot:
Yes, for sure LOS without GAPPS is working. Have it running myself with some alternative essential system services (AuroraStore,UnifiedNLP)

Just in case someone wants to use additional GAPPS, it is mandatory to install them directly after LOS flashing, no reboot in between...

Writing to external SD

Hi,

Thanks for the effort of making this work.

I have a question regarding saving the photos on external SD. As stock camera does not support this, I tried several other camera apps and they all have the common problem: when files are created on the card they, although perfectly valid, are shown as having zero size. Same happens if I put a file there using, for example, Total Commander. Some apps are able to see these photos (e.g. native Files, third-party gallery when validity check is turned off, Total Commander), some others don't (e.g. native Gallery, Nextcloud). All apps that are able to see the files report zero size. All necessary permissions are in place, including this fancy new-ish external SD access.

I narrowed the problem down to storaged. If I kill it, it's gets restarted (by some watchdog), then I see short notification about SD card check and right after that the files appear as normal and all apps are able to see them.

Although I made a workaround in Tasker to kill storaged every time Camera folder gets modified (it waits until screen turns off to avoid operation interruptions), it's quite annoying to resort to this dirty hack.

Is there a better way to fix this? Has anyone encountered this problem at all?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Digger_m:
Anything downloaded or stored created by apps fail on the SD card I have found. To save successfully to SD card I've found its got to be put there via USB. That sucks I understand it's part of the security android employs now. ? I gave up trying to save picture to SD card now I will periodically move them via usb

Hi, I have configured my microSD as internal ("adopted storage") and photos/downloads/etc. are stored on the SD without any issue.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Digger_m:
But can you then remove the card and access the data stored on it?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Kippy51:
Of course he can't! If you format SD as internal it's formatted as ext4 and encrypted. Basically it becomes part of your phone. His comment was nonsense.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] gnarf49:
Not nonsense, just naming a helpful workaround/solution. Yes, card is ext4 and encrypted, but who is using the microSD as a portable device by taking out and putting into other devices? Especially considering S7 is waterproof, so frequently opening the SIM/SD slot is not recommended.

Access via USB just works, no limitations there, because Android uses MTP since v4 or so.

One additional benefit is that the limitations imposed by FAT filesystem on mobile SD are gone, like special characters in filenames.

The only downside I can see is that TWRP backup to local SD can't be used after a full phone rebuild. But as said above, you can copy the backup via USB to somewhere else.
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Digger_m:
For me the reason for the SD card is to keep stuff on it and if the phone dies it's still available. This phone as plenty of storage don't need to add to internal with an SD card . That's my thought. Still the fact that the OS restricts what we can write to our SD cards is very annoying!
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Hemuli:
You actually can, there are guides on how to do it.

You could use some cloud service or, if you don't like that, use rsync to backup them to your own computer. What if the SD card is the one that dies or you lose it with the phone?

Hello! Is anyone have similar to this issue https://amp.reddit.com/r/LineageOS/...8_file_size_0_bytes_after_copying_to_sd_card/ ?

Thinking but dont remember since what build I got same bug on this rom - files copied to external sd have 0 bytes size in all apps before remounting sdcard or renaming a file. sd samsung 128 gb. tried format to exfat and fat32 with no luck.

Just seen posts above about same issue. As I remember it started after some update. Where can I get older builds to narrow problem?
[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] rho-bot:
Yes, same behavior here. Not sure if this is a bug or a security feature?!? But I consider this as a bug.

Had a similar situation with Whatsapp backup restore. File was seen by whatsapp, but filesize reported 0 bytes. Was a privacy protection issue, where the allowance during access notification was not enough, rights had also to be granted by App settings.

I also recognized some other minor flaws:

- LED notification for apps sometimes stops working, system restart needed

- Live Display Automatic mode sometimes stops working (stuck in nightmode), toggling the mode helps
