I just received my Meizu M3 note and I am facing a problem with my front camera while using the Facebook messenger app (only my selfie camera, the back camera operates well). Actually the screen start to shake and the picture is not stable. Although this problem comes only when I am using the messenger app and not the instagram or just the phone camera itself. Is it a software problem or a hardware one? Is there any solution? I did uninstall and reinstall this app and nothing fixed.
