Meizu mx4 whatsapp bug

Ive noticed that if i want to send a picture from whatsapp, and if i change my mind i cant go back to whatsapp and i have to restart the phone.
Anyone encounter this problem?

You can swipe up the home button to go back.


Some of these might not be work for Flyme 4 but most should… Might want to check this out:
