In jolla-camera (and advanced-camera on continuous focus mode), the camera refuses to take a picture sometimes when you press the capture button, unless the entire frame is COMPLETELY STILL for long enough for the auto-focus to work.
On Xperia X, XA2, and XZ2 Compact (community), running 4.3, the focus never took more than one second, and a small amount of motion never caused this.
The amount of motion necessary to cause the focus to hang is TINY.
Try to take a picture while very very gently moving the camera (nowhere near fast enough to create motion blur).
A picture is taken shortly after pressing the button.
The picture will never take, until the image is perfectly still.
workaround: manual-focus mode in advanced-camera doesn’t hang, although continuous-focus mode DOES hang
