Why is the exposure time/ shutter speed for my phone capped at 1/2 (half a second)? I would like to take photos with an exposure time of up to 30 seconds. Even when installing other apps, like GCam or Open Camera, it is not possible to increase the exposure time. I have an Fairphone 4 with Android 13.

In the screenshot you can see that the exposure time (S) is at the maximum value.

Do you have the same "issue" as me, or know how to fix it?

I'm tagging this as a "me too" but otherwise providing no other useful information or a solution.

I notice the main camera on my Moto G 5G is capped at 1/3 of a second, but my buddy's LG V20 will go all the way up to 60 seconds using the same version of OpenCamera. (Yes, we both have API2 enabled.) I'd be interested to see if this can be twiddled e.g. with root, or possibly by poking some config file with ADB or something.

Might be a safety feature preventing the sensor from overheating. There's not really a physical reason for why you couldn't expose the photo for hours so it must be capped in the software.

Have you tried GCam's night mode? I mean the one you download with the browser, not the one in Play Store.

I just tried it. When using it (in a bright environment, had no dark environment/ night at my hands) the time to take the image felt like 1s max. So not that much longer. Also I would like to control the exposure time...
