Images displayed sideways after upload

Hi!

After installing the plugin all seemed fine, but it was noticed that many newly uploaded images were now displaying sideways, so the plugin was disabled.

The plugin default settings were used:

Image Metadata Stripping = Enabled
Preserve ICC Color Profile = Enabled
Preserve Image Orientation = Enabled
Log Errors = Enabled
Plugin Information – Compatible image processing library active: Imagick 3.7.0

– some images which were photographed using iphone camera were sideways, but not all.
– some images which were photographed using android camera were sideways, but not all.
– and so on, randomly occuring.
– it was noticed that the original metadata included [orientation] value, after stripping then this [orientation] value was gone. Is this expected, given the setting “Preserve Image Orientation = Enabled”?

Please advise if possible.

Thanks.
