FP4 - gcam-port

[AvidAlbatross]

Not that I can find, nope

[tom_rhodes]

Hi, thinking of getting an fp4 as my fp2 is creaking now. Does gcam solve most camera issues? Do I need to root the fp4 and does that bring consequences? Like banking apps not working etc.

Is it likely fairphone will publish camera-api2 updates soon to allow 48M and ultra wide lens access?

Cheers

Hello. In my opinion, it solves most of the issues, but to be fair, the stock camera app also got much better over the last updates. You don’t have to root the phone to use gcam. You just need to enable installation of apps from unknown sources. (It should prompt you when you try to install the apk file.)

Is it likely fairphone will publish camera-api2 updates soon to allow 48M and ultra wide lens access?

Yes, but we currently have no idea how long it’ll take. (Note that the issue has been reported for more than 7 months.)

Camera & Camera2 API - missing features & bugs

Yes, that’s precisely how it’s currently implemented. The point is that it doesn’t have to be this way. And the key is indeed to drop the SYSTEM_CAMERA permission requirement, i.e., make the wide lens camera a regular camera instead of a system camera. Which Fairphone can do. Also I have a new update from the support team. I hope it will be done soon. Indeed, we have been working on this request for some time already. I have discussed this again with the relevant department and we have agreed…

[tom_rhodes]

Thanks Razem that’s a great reply. It’s probably a tough thing to get right without the resources of a Google, Samsung, Apple etc. where they can just throw enormous amounts of money at the software to get the most out of the hardware,

Is it possible to install gcam in parallel with stock?

@tom_rhodes

Is it possible to install gcam in parallel with stock?

Yes, it’s what I did
I can take photos with both.

Does anyone use one of the mentioned GCam ports under CalyxOS?

What has to be done exactly, when I don’t have (and don’t want) install Google Services (nor microg)?

I understand that there are some open bugs to fix by Fairphone so that e.g. all 48MPixel can be used as well as all lenses (wide angle camera is missing right now) etc. - Camera & Camera2 API - missing features & bugs

But which port should finally be used and how to set it up?

I saw and tried:

• BSG’s BSG: MGC_8.1.101_A9_GV2a
• Wichaya’s: Wichaya: GCam_8.1.101_Wichaya_V1.5
• Nikita’s: NGCam_8.2.300-v1.8

No matter which one I tried it directly crashes after the start.

[hirnsushi]

Hadn’t used them before, but I just tried it and all three work fine on the latest Calyx release with their GCam Photos Preview installed.

With microG though, if you don’t want to use it have a look at Gcam Services Provider, that only implements the necessary APIs for GCam to function. Haven’t tried it on the FP4 (yet), YMMV

[Smojo]

I tried the Gcam Service provider, but is always says:
“App not installed as package conflicts with an exiting package.” (I should use the photos apk in my case I assume, but the basic apk shows the same problem)

Wondering what the package name of it it is and why it thinks, that it is is already there

[hirnsushi]

Are you trying to install the app-photos-release.apk version? That one get’s installed as com.google.android.apps.photos (the other one as de.lukaspieper.gcam.services rather unlikely to conflict with sth).

I’m not sure if CalyxOS ships with GCam Photos Preview installed by default, either search for it in the settings or use adb shell pm list packages -f com.google.android.apps.photos.
That’s using the same package name as the GCam Services Provider “photos” version to achieve the same thing, faking Google Photos.

Edit: Ah, sorry didn’t read that second part that both show the same behaviour
Interesting, you don’t have microG installed at the moment, right?

[Smojo]

Yes I already tried to figure out what is the issue here.
I used termux on the phone directly to check for google packages:
pm list packages -f | grep google

I saw a com.google.android.apps.photos and removed it. Still the service provides apks fail to install

And yes also right, the “GCam Photos Preview” apk creates a com.google.android.apps.photos as well.

I don’t have microg installed, that is true.

Another package confused me → com.google.android.gsf probably another fake package, which was installed during one of my attempts to make this working.

[hirnsushi]

@Smojo

I saw a com.google.android.apps.photos and removed it.

Were you able to simply uninstall it or did you use pm uninstall --user 0 com.google.android.apps.photos? If it’s the latter have a look at the earlier discussions in this topic, starting here.

@Smojo

Another package confused me → com.google.android.gsf probably another fake package, which was installed during one of my attempts to make this working.

Could you check the path that’s installed to? pm list packages -f gsf (you don’t need to pipe to grep, pm will just search on its own).
The microG one is located in /product/app/GsfProxy/GsfProxy.apk, so clearly recognizable.

[Smojo]

Hm seems to be the microg one:
package:/product/app/GsfProxy/GsfProxy.apk=com.google.android.gsf
No clue when this was set up.

The photos package is here:
package:/data/app/~~CbeWB6Mq5Xwe2ny48G3o-Q==/com.google.android.apps.photos-io4BjoYsdmyFyFrr9bwQqA==/base.apk=com.google.android.apps.photos

I will read the linked topic. Thx

[hirnsushi]

@Smojo

No clue when this was set up.

Are you sure you removed microG in the setup wizard?
Calyx ships with microG by default, and you have to untick the checkbox on first boot to remove it.

[Smojo]

I don’t remember that I un-ticked something explicitly. I just remember that I skipped the setup during the phone setup.

[hirnsushi]

If you have a microG app in your app drawer, or you find something when searching for microG in the settings, you are definitely running microG.

Huh, if that’s the case, those GCam versions should have worked just fine

[Smojo]

I looked for micro and gsf in all apps (showed system apps before) + in settings there is no microg stuff (used the search there as well)

Maybe I can just remove the gsf package as well with pm uninstall ...

Btw. what was the difference again between:
pm uninstall com.google.android.apps.photos
and
pm uninstall --user 0 com.google.android.apps.photos
?

[yvmuell]

Uninstall for user 0 versus uninstall completely (only possible with root)

@rar0

This works because applications truly aren’t fully uninstalled from your device. They are just being uninstalled for the current user (user 0 is the default/main user of the phone). That’s why, if you omit the –user 0 and -k part of the uninstall command, the command won’t work. These two flags respectively specify the system app will only be uninstalled for the current user (and not all users, which is something that requires root access) and that the cache/data of the system application will be preserved (which can’t be removed without root). Therefore, even if you uninstall a system app using this method, you can still receive official OTA updates from your carrier or OEM.

[hirnsushi]

No microG but GsfProxy, interesting. Maybe the Calyx setup wizard only disables it and it somehow got reenabled, not exactly sure how they implemented that

In any case, since you are running Magisk, I’d just create an overlay module to remove those apps, easier to revert if things go sideways.

• Create a folder for it su -c mkdir /data/adb/modules/NoG
• Create empty subfolders for gsf su -c mkdir -p /data/adb/modules/NoG/system/product/app/GsfProxy and have it replace the system one su -c touch /data/adb/modules/NoG/system/product/app/GsfProxy/.replace
• Remove the updates for Google Photos pm uninstall-system-updates com.google.android.apps.photos, check it’s path pm list packages -f com.google.android.apps.photos and repeat the previous step with that information
• Reboot, check if both apps are gone and try installing Gcam Service Provider again

[Smojo]

Hey @hirnsushi, what is the intention of your proposal?
Shouldn’t I save what is in /product/app/GsfProxy/GsfProxy.apk? before overwriting something?

Or what is the purpose of:
/data/adb/modules/NoG/product/app/GsfProxy/.replace
?

Uninstalling the photos updates etc. is clear so far.

[hirnsushi]

On of Magisk’s features is to create an overlay file system which lets you modify / replace system files without touching the underlying file system.

touch /data/adb/modules/NoG/system/product/app/GsfProxy/.replace creates a file that just tells Magisk to overlay your empty folder over the system one, effectively masking its real content while Magisk is active. (Magisk - The Magic Mask for Android, as the tagline says )
Have a look at the documentation if you want to dive in deeper. (had a look myself and noticed a little error in the paths in the previous post, which I’ve corrected )

After a reboot your system sees the folder you created, which in this case makes it appear like GsfProxy.apk isn’t installed, enabling you to install your Gcam helpers which might have conflicted with it.
