It's because you're trying to use libnative_camera_r4.0.0.so while your
device is not 4.0.0. Use the closest available library; for example if
your device is 4.1.2, you should use libnative_camera_r4.1.1.so. This is
a limitation of relying on OpenCV Manager that keeps around the correct
library for your device, but we don't want to rely on it ourselves and
for now we have to manually provide the library.

QCamera being buggy on Android is one of the reasons why we wrote
qml-cvcamera. The other is support for various devices, such as Kinect
and PointGrey cameras.

Hello,
Please take a look at the Qt bugreports.
For example this: https://bugreports.qt-project.org/browse/QTBUG-37525
Or maybe this: https://bugreports.qt-project.org/browse/QTBUG-41273
It seems that video recording on Android depends on the device
manufacturer.
I suggest trying to get a log out of the device and opening a new
bug (if it isn’t a known bug).
Best regards,
Tero
