[Xiaomi Poco F2 Pro (Redmi K30 Pro) Themes, Apps, a] GalaxyTroll:
I haven't had the opportunity to test that particular port because it immediately crashes on my device, which is probably because I'm running a custom rom. For gcam ports new is not always better anyway. The advantage of v7 ports right now is they offer way more customization with custom libs, saturation and sharpness settings, sabre etc.

The reason why I recommended the nikita / tigr gcams is because I found that photos taken with those cams contain a lot more details compared to other popular ports like urnyx gcam, that one shoots blurrier pictures (from what I've seen at least) and it doesn't offer as many customization options to tweak. Because what you'll find is that the settings out of the box might not be the best for your device, you basically have the fiddle a bit with the settings to find out what's best for you.

- I actually notice the same thing, but the urnyx port has the same issue for me. I'm not sure if this has to do with HDR+. Because of HDR+ you'll find that gcam captures a lot of details of your face, pores, pimples things like that, much more than other camera apps, personally I wouldn't be using gcam for selfies. But yeah, HDR+ could be the reason face retouching might not be working the same way as in other apps but don't quote me on this lol.

- If you use my config you should see 3 buttons at the bottom of your viewfinder, leftmost for normal camera, middle for wide angle and rightmost for macro, they should all have icons as well.

- EIS does work for me in the tigr port, although only for 1080p. If you want EIS in 4k you'll need the urnyx port. What I suggest you to do is install both the tigr gcam and the urnyx one alongside each other. I use the tigr gcam for photos and the urnyx one for video. The urnyx 7.3v2.5 gcam on the celso site has a config available for poco f2, so you could use that config for the urnyx port.

The best gcams for poco F2 are in my option tigr/nikita for photo quality, urnyx for stability / video and greatness 7.3 for decent photo quality and stability. What you'll find is that many gcams are based on each other. Wichaya ports for example are based on urnyx gcams, which is why you'll get similar results. Similarly tigr's gcam is based on nikita's which is why they are similar as well. Anyway tigr, nikita, greatness and urnyx are all good starting points.

I have tried many gcams and found that tigr's and nikita's gcam offer by far the best photo quality and I'm not even sure why, because urnyx has supposedly optimized his gcam for our device.

I made a post here a few weeks ago complaining about how my poco f1 got better results with gcam than my poco f2 with urnyx gcam. With the tigr / nikita gcam the f2 destroys the f1 on photo quality which is how it should be, that illustrates the importance of a good gcam port.

This doesn't matter that much because changing configs is not going to cause permanent damage to your device or anything. If you're going to experiment with configs it is always smart to make a backup and just reset to the old config when you accidentally break something. Settings like tone / gamma curves and experimental lib patcher setings might be a little advanced and tbh I'm also not bothering with those. The settings that make the most sense to change are the settings in the normal lib patcher, settings like sharpness, saturation, denoise and exposure compensation.
