No, you can't delete your own questions, you can request an admin to do that but it's unlikely your request will be granted.
To 'messages' at your profile and then you can click on the bin icon/cross icon
One is for blocking a person, one for deleting the messages ^^
You can only disavow them which basically means your question stays up but as an anon question.
You can not delete questions but you can make them "anonymous" so their not related to your profile anymore ;)
There should be a little garbage can looking button you can press. I have that on PC, I don't know if it's the same on smartphone.
