I have and like stiffbud said, the android wallet is really buggy. I would not trust it with any funds to be honest with you.
It even supports RBF so you can start with low fees and raise them if it's not included in a block for a certain time.

That actually looks great, but i will have to waut for feedback from more experienced members. I am not a programmer so i cannot check if there is anything suspicious on the source. I will keep my eyes on this project however, would support for ledger wallets be possibly too?
