[Samsung Galaxy S21 FE] adamuadamu:
It was said hundreds of times: any GCam works properly on Exynos variants of S21FE but none on Snapdragon ones.

BTW lack of GCam for Snapdragon variant forced me to get familiar with pro mode of stock camera app - and I'm nicely surprised with the results - IMO it's not as bad as it's told to be
[Samsung Galaxy S21 FE] ish4d0w123:
And for the 100th time. This is not true. One can dream but your information is so wrong it's not even a dream.

It DOES NOT work on exynos either. Not with full image optimization and all lens access. Without these it is a fake app, a fake gcam, that is nothing more of the stock camera app,actually even less.

The point is to have direct hardware level sensor access so gcam can do its magic image optimization and you simply don't have this on this phone. It does not matter if it is snapdragon or exynos, the phone protects against that kind of access to the camera. And no one is bothered by it, people are satisfied to have found some half baked gcam app that is nowhere as good as the genuine gcam would be with real hardware level access.

So: no there is no real working gcam for s21 fe.
[Samsung Galaxy S21 FE] ish4d0w123:
No I don't think so. It is difficult if not outright impossible to gain the necessary direct hardware level access to the sensors that gcam needs. And even if you did the connection drops after 2 seconds.

Don't get the s20 fe. Yes its a good phone and may have working real gcam but it is a 2 yrs old model, you can get a better deal at oneplus or xiaomi.
[Samsung Galaxy S21 FE] ish4d0w123:
This is so far the closest we got to a working real version but I must inform you that it is not only the config file that needs "tweaking" but the app too. Yes the config file needs major changes but it's not enough.

I'll look into it but no promises.
[Samsung Galaxy S21 FE] NoHeBetterDont:
Any update?
[Samsung Galaxy S21 FE] manigma:
Do you have S20 FE or S21 FE?

Which version did you install? Ruler, 3D etc?

Does telephoto lens work? Can you post a test shot from the gcam using portrait mode with telephoto lens?
[Samsung Galaxy S21 FE] manigma:
Is there a Gcam mod that supports Telephoto lens of S21 FE Exynos?? I have tried so many versions they all crash when telephoto lens is selected.
[Samsung Galaxy S21 FE] Payne83:
The only gcam that doesn't freeze even if u don't have HDR+ and enhanced enabled is GCam_8.1.101_Wichaya_V1.6 with the configuration for S20 FE. I'm trying to make it work (with HDR+ enabled) by tweaking other settings but haven't managed.

Will try the new BSG: MGC_8.6.263_A11_V8 but doesn't think it will work either.

*I have the snapdragon version.
[Samsung Galaxy S21 FE] raducux:
Anyone found a stable build ?
[Samsung Galaxy S21 FE] Ten306:
This is my configuration of GCAM, (it's the Shamim mod)i use that on my S21FE Snapdragon.

156.49 MB folder on MEGA

11 files

mega.nz

The 3X zoom camera wor's fine, better than stock, and you can shoot in raw.

The main camera crash if you use HDR, or HDR plus.

The ultra wide work's a little bit better than stock, but with a huge vignetting.

In the link you can views same samples of the zoom camera with Gcam and stock.

DON'T UPDATE SHAMIM Gcam, don't work fine, at the moment, this is the best verion for S21FE SNAPDRAGON (but you can try :p).
[Samsung Galaxy S21 FE] Dayuser:
You could mentioned which shamim version you are talking about and what to use with that xml you have shared.
[Samsung Galaxy S21 FE] Randi03:
The version is in the mega link: com.samsung.android.scan3d_8.4.400.423370569.19. You put the xml in the GCam/Configs8.4 folder.
[Samsung Galaxy S21 FE] Dayuser:
All shamim build is based on that google version and latest is 38FIX
[Samsung Galaxy S21 FE] Ten306:
With the neewer version of the shamim gcam my xml don't work, and the camera perform generally worse.

Try if you want, and let us know if it works!
[Samsung Galaxy S21 FE] Dayuser:
So.. Shamim version behind that MEGA link is 8.4.400.42 V20..
[Samsung Galaxy S21 FE] Dark_Requiem:
I've also got the Exynos variant and so far, any GCam build I've tried hasn't been able to use the telephoto lens. Is it available with this one?
[Samsung Galaxy S21 FE] Payne83:
Ten306 has good settings.

Do don't freeze with HDR we have to tweak the following : on system settings->stream configuration the values of every camera(main, tele, wide, front) and in same system settings-> HDR model.

There must be some combination that doesn't freeze the viewfinder.

On Processing functions->noise model we can put the correct for every sensor.

555imx cstark for main sensor

Hi-847 (S20 FE)for tele

Now for wide it doesnt exist the 258imx but we can use S5K3L6 (S20FE).

On Processing functions->auto white balance I don't know which since they don't have the one for our phone. I put pixel 2.

I'm trying all this on the last LMC8.4_R14
[Samsung Galaxy S21 FE] lutbary:
Hello. Thanks a lot for ten_S21FE_shamim xml file and trial with version 8.4.400.. Yes - the 3X zoom camera works a bit better than stock now.

However - night mode is just awfull. Pity that most stuff is buggy as there is no real hardware level access to the sensors.

On the other hand stock night mode is rather good with the September build and overall stock camera version 12.0.07.40 works also ok. Maybe next update to Android 13 will improve the camera further (better/manual control of lenses, expert RAW)..

At least we will get anything at all, since it seems to be just our dream to get a great gcam app for our S21 FE with Snapdragon...

What would we be without our dreams?

Many years ago I had also a dream to keep my S7 (which with the F 1.7 main lens does many things just as well or sometimes even better than the S21 FE) up date with custom ROM.. :cry:
[Samsung Galaxy S21 FE] johnnyman25:
Still no gcam for snapdragon version?
[Samsung Galaxy S21 FE] Payne83:
No nothing working (on main sensor) until now with HDR enabled. Viewfinder freezes.
[Samsung Galaxy S21 FE] xoyantajoy:
Doesn’t work on my S21 FE Exynos version. The problem is same with snapdragon version.
[Samsung Galaxy S21 FE] yac12in:
Can you share lmc exact version and xml please i have s21 fe snapdragon
[Samsung Galaxy S21 FE] yaca_k:
It is too wide on main sensor as it uses wide one in fact. You can check it by covering it with your finger. Mian sensor is on only in Portrait mode for this setup. Thus we can't say much for HDR+ or Night mode for the main sensor here.
[Samsung Galaxy S21 FE] Mrawy:
No solution yet for snapdragon?

The shutter lag from samsung camera it's driving me nuts
[Samsung Galaxy S21 FE] Brea-flee:
Searched the whole net to gather the following informations : an old Gcam based on V6 that had buffer fix is the only working with no freezing viewfinder and hdr enhanced. So either someone finds a solution or make a magisk mod to fix the buffer freezing or a Gcam modder need to implement the old buffer fix in newer versions. Asked everywhere on telegram and making a mod with buffer fix is very unlikely to happen..
[Samsung Galaxy S21 FE] Mrawy:
Can you share the old gcam?

Thank you!
[Samsung Galaxy S21 FE] Brea-flee:
Of course. I tried to attach the apk but it seems like failing every time. Here's the direct link to the apk in telegram https://t.me/ucvm_gcam/15363

[Samsung Galaxy S21 FE] Brea-flee:
It's most probably about the Stream config or the image buffer size. Newer gcams needs that and i don't know how to manually extract the stream. It'll solve the freezing issue once someone gets the stream config For Snap S21 Fe
[Samsung Galaxy S21 FE] drkemankesh:
i have s21 fe exynos version. Now which is the last working gcam version and config? and also does the same config work at every gcam version?
[Samsung Galaxy S21 FE] donnelldouglas:
any hope for snapdragon compatible version?

stock camera on S21 FE is very hit or miss for me, quite inconsistent...
[Samsung Galaxy S21 FE] Brea-flee:
I managed to get aux Working 100% on latest AGC mod with just the right stream config. Samsung is probably using a different stream config for the main that's why it keeps hanging. We need to extract it and i couldn't find out just yet how to do it.
[Samsung Galaxy S21 FE] donnelldouglas:
even though this phone was released months ago, it is still very popular in Europe, and I got one few weeks ago... I really hope to find a working GCAM it's such a shame not to be able to use GCAM on this device because the hardware is good and I'm sure results would be great... too bad nobody could solve the viewfinder freezing issue
[Samsung Galaxy S21 FE] Brea-flee:
The results are amazing. I already made xmls with stunning results. The mods can all click pictures if you're fast enough with same results as any other flagship phone. It's just the viewfinder that's freezing after 3 seconds of opening the app or changing between mods. Here's a pic of my dog taken by Shamim's mod.
[Samsung Galaxy S21 FE] donnelldouglas:
great picture. such a shame it's not possible to use gcam longer than 3 seconds on this phone :(
[Samsung Galaxy S21 FE] donnelldouglas:
I found some half working solution on BSG telegram group that fixes ultrawide and telephoto cameras, but still no solution for the main camera freezing issue....

I used this version with package name for Samsung MGC_8.7.250_A11_V13_scan3d

settings-> configuration of modes-> add 21 to black list and 52 to white list.

then change session ID for both back cameras (0.5 and 2.9) to 61456

both telephoto and ultrawide should work now.

still no fix for the main camera freeze...

I really hope someone would find a way around it or a developer would help out, maybe add the buffer fix eveyone is asking for....

any other updates you guys know about?
[Samsung Galaxy S21 FE] johnnyman25:
The main camera freeze after so many months is unreal...
[Samsung Galaxy S21 FE] Daywho:
Such a shame camera suck on this phone, my old one plus 6 with gcam shoot better pictures than this.

Would never bought this phone if i knew about the crap camera and not be able to install working version of gcam.
[Samsung Galaxy S21 FE] sergsinger:
Pixel is your choice next time.
[Samsung Galaxy S21 FE] donnelldouglas:
yeah it is really disappointing no solution is found after so long. I tried everything, at this point without one of the main developers taking on this project it's probably never going to get fixed...everything else is working fine for me but the camera is a disaster, lagging all the time and generally mediocre shots if conditions are less than optimal...if no gcam fix comes out will probably switch to pixel in couple of months.
[Samsung Galaxy S21 FE] dokuzovski:
I have contacted Arnova8G2 developer. He gave me some instructions and provided test version. He is trying to make it working on S21 FE. I will give you with the link from the thread on github. If you succeed please make config file for the settings. Good luck

Yeah I also tried the steps in the above GitHub post but still the freezing persists. Hopefully Arnova8G2 will find a solution

It will be a miracle if viewfinder will be fixed

Let's see.
[Samsung Galaxy S21 FE] Solega:
I hope it happens soon. It has been ages
[Samsung Galaxy S21 FE] yaca_k:
Taking into account how much time passed with no progress I think it will just not be fixed at all. Soon the developers will focus on newer models. That's life.

Just bought the s21 fe exynos, Can I have a link for the best Gcam you've reached to after all that thread please!
[Samsung Galaxy S21 FE] urke1978:
Finally good news. after the latest phone update all three rear cameras work on gcam.
[Samsung Galaxy S21 FE] aweeeeeee:
for exynos or snapdragon?
[Samsung Galaxy S21 FE] urke1978:
My is Sd.
[Samsung Galaxy S21 FE] aweeeeeee:
the same as me Can you give more information? What version did you use?

Thank you.
[Samsung Galaxy S21 FE] Randi03:
urke1978 has the EUY CSC firmware revision, which is G990BXXU6EWH5 and it was an update of over 1gb. Most people have the EUX CSC firmware which doesn't have an update at the moment. We are still on the august patch of 314 mb and for me Gcam still freezes but I would be curious to know what Gcam he used. Also, I do not know if we can flash the EUY firmware safely but I guess it's better to wait for an update.​
[Samsung Galaxy S21 FE] urke1978:
Bsg and Bigkaka version..They do both.
[Samsung Galaxy S21 FE] Randi03:
You're right, I just received G990BXXUEWH5 on my EUX csc and installed AGC8.8.224_V6.0_scan3d from BigKaka, I enabled only RAW and no more freeze on any lens. HDR enabled too. Wow.
[Samsung Galaxy S21 FE] Made Of SuN:
That's right, it works well, Wait for the front cam
[Samsung Galaxy S21 FE] Moaske:
OMG!! It finally works indeed! No more freezes! :D

I checked my updates history cause I remembered getting an update recently that was over 1GB (1396.33MB to be exact). My firmware numbers do not match the above mentioned though... But I DO have a Snapdragon running the thing.

I used this package mentioned above: AGC8.8.224_V6.0_scan3d from BigKaka. Here's where to get it: https://www.celsoazevedo.com/files/android/google-camera/dev-BigKaka/f/dl31/

I used it without a configuration file and without tinkering with settings and worked straight away. I only miss the wideangle lens (main and tele working fine) atm, so I'm gonna try the Galaxy S23 config, to see if that may fix the wide lens. :)
[Touch Cruise ROM Development] Vamshi:
Sorry for wasting a thread here..

After around 3 months of fun, experimenting with different ROMS my touchscreen has stopped responding:(. I've searched in this form and could not find any solution. Thats why I'm planning to take it to the Customer Care. Before that I need to get it back to the original shape. Here lies the problem..

I've installed the original ROM. Now when I try to install the original SPL there is a notification which needs my approval which I cant approve as my touchscreen is not working. Any other solution to restore the original SPL.

I've tried the one here:

[Google Pixel 5 Guides, News, & Discussion] NetSpeedZ:
I currently have Android 11 Stock ROM installed on 'B' slot on Pixel 5. Everything runs and operates fine. When originally reinstalling the stock ROM, I was sure I was booted to B slot so when I installed stock ROM it would be installed on A slot (missed something along the way and ROM installed to B slot).

Would like to switch from B slot to A (OCD reasons :) ).

Is there an easy way to do this without losing data and having to reinstall the stock ROM?

Assistance would be appreciated.

[Google Pixel 5 Guides, News, & Discussion] NetSpeedZ:
Hello -

Appreciate the quick response.

Not sure how this post applies to my question, i.e., copying from Slot B to Slot A. Would need some steps to follow so as to not brick anything.

------------
[Google Pixel 5 Guides, News, & Discussion] lebigmac:
Here the awesome @harpreet.s method that I was telling you about...
[Google Pixel 5 Guides, News, & Discussion] NetSpeedZ:
I understand that 'swapping' slots can be done from fastboot, however, will this cause the phone to boot to Slot A (if swapping from Slot B) with a working ROM?
[Google Pixel 5 Guides, News, & Discussion] andybones:
it looks like those commands just change from Slot A to Slot B, doesn't swap the actual data from Slot A to Slot B.

(I don't see it hurting to try booting and if you don't boot to a working ROM, simply hold volume down + power to restart back to bootloader to swap back to current slot)
[Google Pixel 5 Guides, News, & Discussion] NetSpeedZ:
Copy that. Looking for a way to copy current boot ROM from Slot B to Slot A.

Will attempt to run the commands just as a learning experience.

Appreciate the clarification.

------------
[Google Pixel 5 Guides, News, & Discussion] andybones:
Very welcome, my friend.

The past 30 minutes or so I've been looking into this for you.

The most exciting thing to me, being on Android 11 with a working TWRP, you can easily boot to it and pick which slot to boot to.. so, can this be used as a "dual boot"?

It would be cool to have my current ROM crDroid on say Slot A, and then on Slot B try out something like CaylxOS..

If you are running Android 11, perhaps an option would be to make a backup of your current ROM on Slot B.. Then, change to Slot A and restore the backup, thus, moving from Slot B to Slot A. And maybe during your process you can test the dual boot theory of mine above.
[Google Pixel 5 Guides, News, & Discussion] NetSpeedZ:
I think I tried making a backup a while back on an older Moto X4 and then restoring it to the opposite slot (using Android Pie). Could try it on Android 11 and test. Will report back what works, etc.

------------
[Google Pixel 5 Guides, News, & Discussion] lebigmac:
I'm digging that dual boot theory by @andybones

Wish I had access to a dual boot slot device to give it a try!

@NetSpeedZ If switching boot slots is not good enough for you then you could try this at your own risk :

Boot into custom recovery (TWRP, OrangeFox, PBRP)

adb pull all your slot _a partitions to your computer as a backup (system_a, product_a , vendor_a and whatnot)

overwrite all slot _a partitions with slot _b partitions

I'm sure there's a more elegant way of doing this but this is how I would do it.

This example will overwrite system_a with system_b :

adb shell
su
dd if=`ls -l /dev/block/by-name/system_b | awk '{print $NF}'` of=`ls -l /dev/block/by-name/system_a | awk '{print $NF}'`

If you want to avoid bootloop you should probably overwrite all slot _a partitions I guess.

Please report back your results.

Good luck! (y)
[Google Pixel 5 Guides, News, & Discussion] NetSpeedZ:
When you say I would need to flash all _a partitions, are you referring to /recovery_a, /bootloader_a, etc?

------------
[Google Pixel 5 Guides, News, & Discussion] NetSpeedZ:
Made a backup of Slot B and then immediately rebooted to Slot A, then recovered the backup made of Slot B. No error when recovering the backup, however, when I rebooted - went straight to Fastboot mode. Powered off phone, rebooted and it booted back into ROM on Slot B :-(

------------
[Google Pixel 5 Guides, News, & Discussion] andybones:
This was my results as well when I tested the restore/backup.

I am very new to this partition layout, being new to Pixels.

I used hTC devices alll up until now, which had it's own recovery.img

So I am still in habit of wanting to call it a "nandroid" backup, but OP has informed me that is an outdated terminology.

So, is it safe to confirm that restore/backup (nandroids) are not working?

Or are we not doing it correctly?

I'd love to know as I do miss being able to more or less run other ROMs by being able to backup and restore to my current position, and keep backups of the ROMs, or figure out if dual booting is possible.

WAY back when the hTC M8 was released (R.I.P Nick) was kicking butt with his port of "multirom" -- back then as a "Developer" I mean tinkerer, it wsa EXTREMELY helpful being able to test on my daily device, and then reboot into my working ROM.

It would be really cool to have say the stock ROM on Slot_A and crDroid on Slot_B

If this wasn't my DD I would give it a try. I think I would go about it by rebooting into permanent TWRP. I have crDroid on Slot_A, so I would reboot into Slot_B in TWRP, and flash a ROM. ProtonROM most likely. and see how it goes.
[Google Pixel 5 Guides, News, & Discussion] NetSpeedZ:
It appears the backup/restore function works, just not for restoring to a different Slot. I've used the restore backup/restore function to same Slot as backup was made from. I was able to restore fully after I rebooted phone and then powered off the phone and powered back on.

------------
[Google Pixel 5 Guides, News, & Discussion] andybones:
Well that's awesome to hear! Perhaps when I tried my restore, my slots got changed.

You most likely did, but just a thought, did you restore the boot.img when doing your restore to the other slot? Maybe it worked, but had no boot image?
[Google Pixel 5 Guides, News, & Discussion] NetSpeedZ:
Copy that. I restored the entire backup - which I assume restored the boot.img (?).
[Google Pixel 5 Guides, News, & Discussion] andybones:
Depends on the backup you made. You can see when you go to restore the backup and can pick and choose what you'd like to restore, or within the backup folder (here's a recent backup I made).
[Google Pixel 5 Guides, News, & Discussion] NetSpeedZ:
Looks similar to the backup I made, i.e., the boot.emmc.win appears to be the boot image.
[Google Pixel 5 Guides, News, & Discussion] andybones:
Darn, well that's all that's coming to mind for reasons why restore works on one slot and not the other.
[Google Pixel 5 Guides, News, & Discussion] NetSpeedZ:
Guess I could try and flash stock boot.img from bootloader to Slot A . . . . . 'Couldn't 'hoit' :)
[Google Pixel 5 Guides, News, & Discussion] andybones:
Very good thinking!

And, now that you mention it, if it were a rooted backup/restore, perhaps the magisk_pathced.img has issues, best of luck, my friend!

If you would be kind enough, would you test my theory about dual booting?

If possible, keep your current slot as is, reboot to the un-used slot, flash ROM, and see if they both boot. -- would be highly appreciated, Sir!
[Google Pixel 5 Guides, News, & Discussion] NetSpeedZ:
Copy that. Will test and report back.

Appreciate all your input. It was helpful.

------------
[Google Pixel 5 Guides, News, & Discussion] andybones:
Very welcome!

Thinking more on the dual boot, I believe we would need to split the data partition.

Will be looking into it more.
[Google Pixel 5 Guides, News, & Discussion] NetSpeedZ:
Looked into flashing custom ROM and it appears from the various ROM installation instructions that a full wipe is needed before installing. Not sure I want to go that far into this testing of the dual ROM theory as I've got quite a bit of time 'fine tuning' the stock version I currently have installed.

If I misread those instructions, be happy to try testing if I had some step by step instructions on how to flash the custom ROM without touching the existing stock ROM.

Would have liked to find a way to move my existing stock ROM install to Slot A, however, it looks as if I will need to wipe the phone before doing that, ensure I'm on the opposite Slot (in my case Slot B so I can install Stock on Slot A).
