Today you're going to learn a bit about GCam. There is a lot of detail about this app floating around online, and that's exactly why many people aren't willing to try it: it asks for some time and a bit of a learning curve before you can really pull the most out of your device with it.
First, let me be a little more conceptual. I want to talk about Google Camera so you actually understand what it is — so that next time you can update it on your own, without coming back to this guide. After that, you can run the whole procedure independently.
And let me start with the most important warning: Google Camera doesn't work miracles. It won't transform your phone's photography. It simply uses the same hardware in a different way.
What is GCam?
So what is GCam, this much-talked-about APK, and why do people choose it over their phone's stock camera app?
GCam is Google's official camera app for the Pixel. What circulates out there is nothing more than that app, modified to run on phones from other brands.
What it does well
So why did Google Camera get so famous? I've used this app on other phones, and today I'm back to using it on my Galaxy S23 Ultra. What are the high points, at least in my use? Sharpness, HDR+ and better color processing.
Sharpness, because I feel it processes the photo less than Samsung's app does — I get a slightly rawer image. Color processing, because I prefer the way it handles and manages color: it gives me more natural tones.
And HDR+, which I don't use all the time, but it's worth knowing how to. The way I see it, it has more dynamic range. Meaning what, exactly? The sensor captures the information in the highlights, captures the information in the shadows, merges them and delivers a more balanced image.
That's why you sometimes see HDR shots that look like someone dragged too much detail out of the shadows and too much out of the highlights, and the whole thing turned into a mess. So it's worth learning how to use it. Google Camera gives me a bit more flexibility there, and I preferred its results over Samsung's stock app.
GCam is a modified app
That said, it's important to keep in mind that because this APK isn't an official app for the devices you'll install it on, it isn't on the Play Store.
That's also why you find a jumble, an endless list of versions, when you go searching for GCam. What are all those versions? They're incremental updates, extra features, or anything else people change in the APK — they rename it so they can simply ship an update. Since it isn't on the Play Store, there's no automatic update, and you have to go chasing those versions yourself.
That's what makes the process a bit annoying, and it's also why I'm writing about it: so we can clear the subject up calmly.
The APK and the config file
You'll need two files: the installer (the APK) and the configuration file.
The APK follows the same structure as any other app. That's what Samsung does: its camera app uses the camera hardware normally, with Samsung's settings. And what are we doing here? We're using a different app, with settings from other users who already tried it and shared them, just so we have a starting point. Beyond that, it's the same thing.
I use one specific version of the APK together with one specific config file — that was the combo that worked best for me. And again: it isn't perfect, things break, some features really aren't available, but for my use it's all fine.
I don't host those files here, because every device asks for a different combination: the APK that runs smoothly on my Galaxy may crash on yours. The path is to look for the APK version and the config preset made for your model — and honestly, that's the real work in this whole process.
Installation
Now for the installation itself. With both files in hand:
- Install the APK normally and give it the permissions it needs to work.
- Move the config file into Internal storage › Download › AGC.9.2 › Configs. That folder name follows the APK version — mine is AGC.9.2, yours may be another.
Once that's done, your GCam is ready to go.
Getting to know GCam
Overall, GCam's interface is similar to your phone's native camera, so using it is fairly intuitive, with the classic modes: photo, video, portrait and night sight. The one difference is a small delay when you switch lenses, because the app has to reprocess everything.
On the main screen you also get shortcuts to the quick adjustments: HDR, exposure, white balance, watermark and the Leica-style vignette — which I personally like a lot and use all the time.
Finally, a warning about the More settings menu: be careful with those advanced options, because it's easy to throw the whole app out of shape. If you don't know the subject well, my advice is to leave it alone.
GCam vs. the Samsung app
The front camera was the only point where I preferred Samsung's photos. GCam's selfies come out with a smoothing that, for selfies at least, doesn't work for me.
Final thoughts
That's the end of the GCam saga. I hope I cleared up the main points.
The procedure itself is very simple: the real challenge is finding the right files, the ones compatible with your phone model. Until you land on the combination that works properly, it can be a tedious process. In my case, I feel like I'm finally making the most of my Galaxy S23 Ultra's cameras. Video recording has been pleasing me a lot too. Some features crash or don't work well, but for my day-to-day use that's not really a problem, since they're features I don't use.
Because this is a ported app and not an official one, there's no technical support to fall back on. The key here is testing: explore the app, see which features meet your needs, and work out where it fits into your routine.
Although this guide focused on the S23 Ultra, the logic of the process applies to practically any smartphone. Once you understand the concept, it gets much easier to search for and find the specific files for your device.
And finally, there's no fixed rule: you can switch freely between Samsung's native camera and GCam, taking the best each one has to offer in each situation. If you want to understand what Samsung's app is doing on the other side of that choice, I went deep on it in the note about Expert RAW or Pro Mode.
I hope this cleared up your doubts about what GCam is and how to make the most of it.
