Camera app opens upon phone waking up using Motion Launch's swipe up

[anon(9263092)]

I experience a weird issue lately. Sometimes when I'm waking up the phone using the Motion Launch's swipe up, the camera app opens although it wasn't even run before.
Obviously this is not the expected behavior as swiping up should just take me to the home screen.
The issue reproduces randomly, it is not consistent. I can't tell what triggers it but it's pretty annoying.
Did anyone ever run into this before?

Thanks.

When the phone screen is off, and it is held on landscape mode, holding the volume up button will activate the camera. So are you sure that you are not accidentally holding the volume button?!

I'm sure. It happens while the phone is in portrait mode and I don't hold the volume buttons.
