Can anybody tell me if you can record with the camera in the ROM?? I can't even do a Boomerang on instagram.

I found this thread of how to support oms in lineageos

It is possible to support​ with this thread
[Samsung Galaxy Alpha] Michilon:
Unfortunately at the moment there are no known ways to record . The inability to record is unfortunately an unresolved bug of this rom . Hopefully in beta 9 .
[Samsung Galaxy Alpha] davidcaicedo123:
Which one is the Beta with less bugs? Just want to know
[Samsung Galaxy Alpha] modpunk:
Yes, that's the issue. You can edit /system/etc/audio_effects.conf and remove everything inside the brackets of pre_processing and output_session_processing at the end of the file and retry. It is strange that the blobs segfault for you, they work just fine here.
[Samsung Galaxy Alpha] YokoBR:
Mine is g850m.
[Samsung Galaxy Alpha] modpunk:
That could be the reason.
[Samsung Galaxy Alpha] YokoBR:
It worked, bro! Thanks!
[Samsung Galaxy Alpha] YokoBR:
This fix has also fixed many other problems, like before, when I connect to the my car's bluetooth I had to reboot the phone to connect again, or it would be muted. Now it connects flawlessly, all the time.

Spotify had a loud noise before normalizing sound, now it's much better as it has the same volume all the time.

Also, facebook videos hanged back then, now they all play fine.

Everything that uses audio seem to be smooth.
[Samsung Galaxy Alpha] joseph18jk:
Plz fix the camera

The camera won't work
[Samsung Galaxy Alpha] victoram:
IT WORKS

The above mentioned fix also fixed video recording and no more crashs at whatsapp/facebook!, nice find [MENTION=6284133]YokoBR[/MENTION] , i am using a g850m too, i recommend anyone to use this fix, does it remove any function?
[Samsung Galaxy Alpha] davidcaicedo123:
Hey, I'm having a bug with the beta, the problem is that when the battery percentage gets on 15% the screen goes black, don't know why or how, it says system UI crashed. Any fix or is someone having this problem?
[Samsung Galaxy Alpha] victoram:
never had this, what alpha version you have?
[Samsung Galaxy Alpha] YokoBR:
[MENTION=4297219]modpunk[/MENTION] maybe would be good to have this on the first page, on the know bugs or maybe even make a flasheable patch :)

---------- Post added at 12:23 PM ---------- Previous post was at 12:13 PM ----------

Sorry, I didn't saw your question. No, it won't remove any function or feature. They're just pre/pos effects to equalize, normalize, to give better audio quality. But I can't see difference.
[Samsung Galaxy Alpha] YokoBR:
G850M Audio Fix

I've made a flashable patch to fix video recording, whatsapp/skype calls and a lot more.
[Samsung Galaxy Alpha] davidcaicedo123:
SM-G850M, I know, its strange never had this problem before.
[Samsung Galaxy Alpha] YokoBR:
I had only with beta 7 and 8.
[Samsung Galaxy Alpha] YokoBR:
I've tested the patch. It works. For those using SM-G580M that doesn't have root or don't know how to edit system files, just flash this with TWRP.
[Samsung Galaxy Alpha] subrashi cat:
Is this patch just for g850m or could it be used for g850f?
[Samsung Galaxy Alpha] O_Yashiro:
I have SM-G850F and i have the same problem, but that fixed the issue.

One issue i keep insisting on though, how can i initiate video calls through my operator(3g calls or whatever you may call them)?
[Samsung Galaxy Alpha] modpunk:
#lineageos-exynos is the new channel
[Samsung Galaxy Alpha] nuno.f.ferreira:
I guess you're in the middle of rebranding cm to lineage and build system is currently broken. I believe you've missed s/cm/lineage/ in device/samsung/sltexx/vendorsetup.sh but that's not all although I don't know what "all" is.

Catch you IRC one of these days.
[Samsung Galaxy Alpha] modpunk:
The vendorsetup.sh can be removed. It is obsolete in the meantime. Building the ROM works just fine for me. However I should update the README. Several repos aren't needed anymore.
[Samsung Galaxy Alpha] nuno.f.ferreira:
Not for me. What do you "lunch" then?
[Samsung Galaxy Alpha] echo124:
Auto_enable_data on mms please ;)
[Samsung Galaxy Alpha] modpunk:
I've updated the README and vendorsetup.sh. Don't forget to use the TESTING branch in android_device_samsung_sltexx
[Samsung Galaxy Alpha] nuno.f.ferreira:
Still no joy, sorry. I get.

# lunch lineage_sltexx-userdebug

build/core/product_config.mk:245: *** Can not locate config makefile for product "lineage_sltexx". Stop.

Device sltexx not found. Attempting to retrieve device repository from CyanogenMod Github (http://github.com/CyanogenMod).

Repository for sltexx not found in the CyanogenMod Github repository list. If this is in error, you may need to manually add it to your local_manifests/roomservice.xml.

build/core/product_config.mk:245: *** Can not locate config makefile for product "lineage_sltexx". Stop.

** Don't have a product spec for: 'lineage_sltexx'

** Do you have the right repo manifest?

What I can see.

setup-devices.sh still expects to find cm-proprietary-files.txt instead of lineage-proprietary-files.txt and Since $DEVICE in that context is slte, not sltexx it will always produce an slte-vendor-blobs.mk in vendor subtree.

Fixing setup-devices.sh to work with lineage-proprietary-files.txt instead doesn't change the outcome.

Additionally adding a symlink device/samsung/slte -> device/samsung/sltexx makes extract-files.sh run without errors for me but the problem remains.

lunch (with no param) knows about lineage_sltexx but still the error happens.

Also there is some broken references between vendor/samsung/slte (we can add a symlink sltexx) and device/samsung/sltexx. For instance in device/samsung/sltexx/BoardConfigVendor.mk there is a "-include vendor/samsung/sltexx/BoardConfigVendor.mk" but no path vendor/samsung/sltexx exists unless you symlink it.

I'm thinking that there's some hardcoded expectation on finding cm-* devices, considering cm.mk et al but I haven't investigated further but since it's working for you it must be something else.

Any pointers?
[Samsung Galaxy Alpha] modpunk:
Follow the README then it works ;)

Wow! Didn't realize LineageOS had its own repo already. Bye-bye CM!

setup-devices.sh is still expecting the old files but there's no problem coming out of it.

Thanks for the heads-up. Building the TESTING branch as I write this. Let's hope no more surprises appear now.

testing, nfc, fingerprint

Hi everybody,

I 'm new here, cause I recently got galaxy alpha from a friend and I 'm willing to contribute to this ROM. So I've build the ROM from the latest TESTING branch and I'm currently testing it. I hope that this weekend I 'll find time to add support for fingerprint sensor and heartrate sensor based on my experience with my old phone, which was pretty similar (S5 mini SM-G800F). However my time is limited due to upcoming exams, so don't expect much from me this month.
[Samsung Galaxy Alpha] davidcaicedo123:
Me too, and then I clean installed beta 6, the problem is still there, any fix?
[Samsung Galaxy Alpha] YokoBR:
Even installing the patch above? First of all, format your /system partition before flashing beta 8. Then flash it, and afterwards flash my patch above. Wipe dalvik cache and you should be good.
[Samsung Galaxy Alpha] davidcaicedo123:
Ok, but how can I format the system partition, where's that option? :D
[Samsung Galaxy Alpha] YokoBR:
Touch "Wipe" on the main menu, then check the /system option. Then go back to the main menu, install then select the beta 8 file, then the patch.

[Samsung Galaxy Alpha] Michilon:
I flashed the zip file , but despite this I can't still record with the camera . I need to do another step ? I have a g850f .

---------- Post added at 10:40 PM ---------- Previous post was at 10:37 PM ----------

It is very unlikely that in the future there will be 4k in this rom.However , you can change screen resolution with some specific apps . I strongly advise you not to change the resolution . Because these apps do not always do their job well . For personal experience , I recommend you make a backup of everything , before proceeding with the increase in resolution . If you do this , and if it succeeds , publish the screenshot of the result ( please ) . It could also help someone else .

If you can't reset the original resolution from the screen , I advice you to receive a call , before proceeding with the rom . This tweak save me some times but not ever .
[Samsung Galaxy Alpha] YokoBR:
Idk if it does work with 850F. The patch is for 850M. AFAIK this sound problem doesn't affect 850F.
[Samsung Galaxy Alpha] Michilon:
Thanks anyway
[Samsung Galaxy Alpha] davidcaicedo123:
Dude, I meant record in 4K, this phones records up to 4K, but this ROM does not give the support to it
[Samsung Galaxy Alpha] Michilon:
Probably in the future it will be possible to record in 4k

Galaxy Alpha REBOOT ERROR

i used Google Translate.

Galaxy Alpha(SM-G850S, Korea, SK Telecom) is in use.

TWRP : 3.0.0.0

before leneage ROM OS : stock 5.0.2

I installed Lineage ROM, but when I turn it on, it does not boot.

Samsung Galaxy Alpha Powered by Android Stops on the screen.

But after removing the battery from here, TWRP will go into cache initialization and boot

Lineage OS boot animation is out and it can not proceed anymore.

If you push the genuine firmware, it works normally.

Should I call this a Lineage OS bug?
[Samsung Galaxy Alpha] YokoBR:
Nope. I don't think that it's compatible with S. AFAIK, it's only compatible between G850F | FQ | M | Y. Those are "SLTE", and S is "SLTES".
[Samsung Galaxy Alpha] victoram:
Very unlikely, we do not have all the camera software, and we are using camera blobs from 5.0.2, it works surprisingly well by the way.

[Samsung Galaxy Alpha] DaneFTO:
[MENTION=8230058]Harinus[/MENTION] I have the same issues and this is going to be such a rookie question, but how can we implement the fix? Although i'm not a stranger around flashing et al, however, is there a noob guide somewhere? I've searched but can't find any or i'm not looking in the right places?
[Samsung Galaxy Alpha] sunsettrack4:
The bluetooth apk isn't a device-specific part, so it would have to be fixed by the LineageOS team directly.

The WBS fix can be included by adding the changes to the device tree.
[Samsung Galaxy Alpha] Harinus:
[MENTION=5623053]sunsettrack4[/MENTION]:

Both fixes can be included in the device tree!

The WBS fix should be placed here:

https://git.cryptomilk.org/projects...it/tree/bluetooth/bdroid_buildcfg.h?h=AUDIOHW

and the MAP-EMAIL fix can be included in a file called:

/overlay/packages/apps/Bluetooth/res/values/config.xml

This does not exist yet for the sltexx but can be created. Other devices like the bullhead already use such an overlay. So the bluetooth.apk or at least its build config is indeed kinda device-specific.

[MENTION=2099501]DaneFTO[/MENTION] Guide how to fix the issue ad-hoc:

1.) Download and extract both zip files from my previous post.

2.) Copy both files to the internal storage of your device.

3.) Get a file explorer with root acces:

4.) Rename the following files:

- /system/lib/hw/bluetooth.default.so to bluetooth.default.so.orig

- /system/app/bluetooth/Bluetooth.apk to Bluetooth.apk.orig

5.) Copy the two downloaded files to those locations.

6.) Reboot

7.) Done
[Samsung Galaxy Alpha] sunsettrack4:
You don't have to change anything in /device/samsung/sltexx to fix the Bluetooth issue. That's not a change in device tree. That was my thought ;)
[Samsung Galaxy Alpha] Harinus:
I am confused :confused: Are we talking about the same thing? :D

As far as i understand the device tree is /device/samsung/sltexx in the local git repo and also a copy of the android_device_samsung_sltexx.git project that is hosted on cryptomilk.org. And thats where both changes will go..
[Samsung Galaxy Alpha] sunsettrack4:
[MENTION=8230058]Harinus[/MENTION] Okay, I just took a look at my build environment.

I was referring to ~/rr/packages/apps/Bluetooth

You are referring to ~/rr/device/samsung/sltexx/overlay/packages/apps/Bluetooth

In your case you add the change to overlay folder in device tree. I thought that the file has to be changed in original Bluetooth folder. Wieder etwas gelernt :)
[Samsung Galaxy Alpha] Harinus:
[MENTION=5623053]sunsettrack4[/MENTION] Thanks for clarifiying ;) Would not have found the overlay attempt either without looking at the repo of the bullhead device!

I will try to commit both changes later today.

[Samsung Galaxy Alpha] sunsettrack4:
[MENTION=8230058]Harinus[/MENTION] I guess you don't have the permission to push the changes to modpunk's repository. You can either create your own repo on Github and import the code to commit the changes there or contact the owner and request the permission.
[Samsung Galaxy Alpha] modpunk:
Awesome, thanks for looking into those issues!

I'm still looking into audio issues. I think the refcounting of devices is the big issue. This simply does not work with our device ...

Unfortunately another issue appeared, that was masked before.. Somehow BUGBASH-308, 302, 543, 264 and 653 have a relation.

Hello, [MENTION=4297219]modpunk[/MENTION]

I'm a regular user of the galaxy alpha. Here in Brazil this phone is a rare one. I'm using the galaxy A3 build cause the battery is great. And I come here everyday waiting for the stable version.

So I have 2 questions:

-The battery of the lineage beta8 is great as in the a3 build?

-There's something I can do to help you with the development?
[Samsung Galaxy Alpha] modpunk:
There will never be a stable version as we can't support all features of the Galaxy Alpha and in the meantime it is hard to get the old blobs working. However the ROM is probably more stable than the other ROMs you find in this forum.

Patches are always welcome.
