Anyone got android camera app recs that allow the user to manually select the settings? Particularly I want to choose which camera my phone is using because the auto-switching between lenses is immensely frustrating, especially for up-close subjects.

iPhone 17 Pro vs. Galaxy S25 Ultra: The camera wars are heating up! CNET dives deep to compare the titans of mobile photography. Are megapixels or processing power more important? What's your top camera phone feature?

The camera phone wars rage on! CNET's been busy putting Apple, Google, and Samsung through their paces to crown the champions of mobile photography. Is it all about the megapixels, or does software sorcery truly win the day? What's your top pick for a phone camera that just *gets* it?

Librem 5 camera hates debugging. You can display 8 characters with gtk while using camera... but if you display more, camera eventually locks up. Happens with both direct drawing and gstreamer textoverlay element.
You can debug over ssh, and other heavy use locks it up, too, but... I take this one personally. #librem5 #phonecamera -

Librem 5 camera/kernel can do three possible resolutions, ~1024x768 @ ~24fps, ~2048x.. @ ~31 fps and ~4096x.. @ ~15fps. Debayering is actually easier and better quality if we downscale at the same time, and that allows best framerate, so we do that (2048x.. resolution).
ARM has problems with cache coherency w.r.t. DMA, and kernel solution is to simply disable cache on DMAbufs for userspace, which means accessing video data is 10x slower than it should be on the CPU. Which means debayering on GPU is attractive, and that's what we do. (gold.frag). GPU can do more image signal processing functions easily, too, so we do some of that.
Unfortunately, we hit the same uncached memory problem at the GPU output. So we use separate thread to copy. All this unfortunately does not fit on one core, so we need two threads, one controlling GPU debayer on frame n+1, while the other one copies video data from frame n. (heart.c). We save resulting RGBA data to ramdisk. This all costs maybe 80% of one core.
From there, Python scripts can pick them up: ucam.py displaying the viewfinder and mpegize.py handling the video encoding via gstreamer. There's basically 0% cpu left, but I can encode ~1024x.. video. Unfortunately that's without audio and with viewfinder at 1fps. Plus, combination of C + Python is great for prototyping, but may not be that great for performance.
Code is here: https://gitlab.com/tui/tui/-/tree/master/icam?ref_type=heads .
At this point I'd like viewfinder functionality merged into the rest of GPU processing. Ideally, I'd like to have a bitmap with GUI elements, combine it with scaled RGBA data, and rendering it to screen. I know SDL and Gtk, SDL looked like better match, but I could not get SDL and GPU debayering to work in single process (template SDL code is here https://gitlab.com/tui/debayer-gpu/-/blob/master/sdl/main.c?ref_type=heads ).
If you can integrate main.c and heart.c, that would be welcome. If you have example code that combines SDL with processing on GPU, that would be nice, too. If you know someone who can do GPU/SDL, boost would not be bad, I guess.

My last Samsung galaxy's camera had the ability to take repeated shots for as long as you set, so as to take pictures of the movement of stars or a creek, but my S20 doesn't have this feature.
I want it back! How do I get it back?
