[Xiaomi Poco F1 Themes, Apps, and Mods] PocoSteve:
Here's a quick FAQ for everyone to read, if you have a problem/question/bug it's probably in here :

Q: I don't see much difference between Gcam and Poco's stock camera! What gives !?

A: Here are some steps you can take to make the image better :

Make sure you have gone to More > Settings > tick "HDR+control" then back to the main view in the camera, change "HDR+" to "HDR+ Enhanced".

You can change the "Final JPEG quality" and bring it closer to 100% (in More > Settings)

The power of Gcam resides in HDR. You can go to More > Settings > HDR+ Enhanced Parameters > and change the number of pictures Gcam takes. Just remember, more pictures might mean a better result, but it's also going to take more time to process.

Q: Portrait mode works only on people and pets!

A: Portrait mode, as the name implies, is for portraits. It will only work on faces (and pets). If you want the same effect on objects, use the "lens blur" mode at the far left.

Q: I want to use playground/AR Stickers ! Where are they ?

A: [*]AR stickers need ArCore and ArStickers to be installed, Pocophone natively supports ARCore, so you can download it from the play store (It doesn't appear as an app icon, but it's there) and AR Stickers needs to be the modded version and not the one from the play store. You can get it here.

Q: Video is shaky !

A: There are two kinds of video stabilization: the one that uses hardware, (the camera sensor is mounted on a motorized holder that moves to counter shakiness of your hands), that's OIS, or "optical image stabilization, and software stabilisation that detects what is in the picture, (takes higher resolution video) and moves every frame back to center to get a stabilized video. that's EIS, or electronic image stabilization. That's what is used in the stock camera app. (my opinion is that it works very well.) Google uses "Fused video stabilization" that is just using both techniques at once on the Pixel phones. Hardware stabilization is not present on the Poco, and software stabilization has not yet been added to gcam ports.

Q: There are dark lines on my picture!

A: Artificial lights (bulbs, neons, etc.) work on mains electricity, which is alternating current, that turns on and off between 50 and 60 times per second, depending on where you live. that's why you get those lines. There is currently no way in Gcam to manually remove them. Use the stock camera app that has a manual selection for correcting this.

Q: Why are my selfies appearing mirrored? Argh! I hate it!

A: You can use an app from the play store called Gcam Tool to mirror them back. However, the picture won't be editable as a portrait shot. (By default, you can edit the amount of blur in the background, or use the "color pop" function that makes the background black and white while keeping the foreground colored) You lose this ability if you flip the pictures with Gcam tool.

Q: Taking a picture with "HDR Disabled" does not work!

A: We know! But that's the "crapify picture" button... Why would you want that?

Q: I installed a new version but it doesn't work !!

A: You need to uninstall any previous version of Gcam before installing a new one.

Q: How to enable 20MP on front camera ?/ Front Camera only goes up to 5mp !!

A: The stock camera uses pixel binning to combine 4 adjacent pixels together to get more light in. 5mpx is a limitation of Gcam but those pictures come out better anyway...

Q: I don't want the sliders on my screen? How can I remove them?

A: You can't. Use BSG's version, or jigs4wkiller's dark version if they really annoy you.

Q: Why isn't 4k@60fps a thing? We have it on the stock camera...

A: 4k@60fps isn't available on Pixel phones. So it's normal that it isn't available in the ports either. Maybe, like any other suggestion, will the developers add it at some point, but it's normal that it's not available.

Q: I've got another question that pops all the time, and I didn't look it up in the thread!

A: Ask it, I'll add the answer here if I can...

I'll try to add things as people ask them and maybe go further into the explanations. the better you understand things, the better!

In general, you have to think about who you should be complaining about your issue. Google, that makes Gcam, Xiaomi, that makes the phone and MIUI, or BSG and sannn111ty who, for free, put some of their free time aside to give everyone a better experience? (tip: it's generally not the Gcam port devs).
