Help me buy my dream phone

I would like to buy a new phone because my old phone is not working properly and here in my country is hard to save money to buy a good phone like a Sony. I had a Sony Z3 compact which I loved but it's not working properly. Some of the apps are not supported and it's getting slow sometimes freezes. I would really love to buy my dream Sony phone, the newest one which has a very good camera so I will be able to take very good photos because I also love photography.
