Blockchain android app did a stupid thing! First of all, Sorry for my terrible English!

On Sep 24 i installed the BLockchain.info android app, before that, i signed up in their web application and made my account strong with 2-step-verification and wallet recovery phrase.

When i used the app, i logged in first time and it wants my verification(email and phone number 2FA), I just fill them and wait for app, but after it all of my bitcoins send to another address without my confirmation ( the address is 16hUh5k9V41EMzcuYW3kmkTCzyqju7RXr1 and yesterday had a another transaction ).

So what's going on exactly?

Their support says it must be hackers or malware, but how? It was their app.
After all, i just installed the app on 3 different devices, each of them shows the same picture in attachment with same address.

Please help me, and tell me what i must do?

Really, I'm SORRY FOR MY ENGLISH!
It was my fault. What a stupid who i am. I'm really sorry.
It is fake application:

Thank You.
