The official camera app doesn't work (because it relies on an API of SailfishOS that normally calls into an Android firmware's driver).

Shutter works.

The main (back) camera has troubles waking up from sleep. But if you reset it, it springs back to life:

Code:

echo ff920000.isp1 | tee /sys/bus/platform/drivers/rkisp1/{unbind,bind}

(Run first "devel-su" to get root).

Which version of mobian are you running?  I have trixie running and no libcamera, I also wasn't able to get megapixels to compile.

As for power, I feel like we need to both fully utilize the hardware acceleration by the OS which is not used by default(all CPU) ad we also need to sleep most of the CPUswith only whitelisted apps getting to even try to access thebig cores or multiple CPUs/freqs.  Ihave a 2013 Nexus 7 tablet and I can easily get 10 hours of web browsing running LineageOS but I can barely get an hour listening to an audiobook over earphones with the screen blanked and wifi/bt turned off on my PP or PPpro.

I was running Mobian bookworm with Phosh for a while (all latest updates from the official repos). It was okay; front and rear cameras worked with the included camera app and web browser but the camera viewfinder was laggy in the app, and photo quality was poor. (These are no surprise--others here have mentioned these issues.)

I then upgraded to Mobian trixie with Phosh using the official repos. I did not test the cameras before going on a OS-flashing-spree. If I go back to Mobian trixie, I'll be sure to test the cameras and report back here.

You're correct about hardware accel. I'm not skillful enough to figure that out, but I have seen how hardware accel. matters big time in other situations (especially VLC/ffmpeg playback). It also keeps the main processor cooler.
