Hi.
Straight to the problem: I have a script, that takes photo using both main and selfie camera. Selfie camera gives me output every time, but the main one almost never. When I execute termux-camera-photo x.jpg manually, I get desired JPEG - this does not happen when I run it via script. That way it only creates 0-byte file.

Android 7.0 aarch64, DOOGEE MIX, bash 4.4.12, termux 0.59

As you can see, there can be nothing wrong with the script:

cd $HOME/storage/dcim
termux-camera-photo 0.jpg
termux-camera-photo -c 1 1.jpg
