[Closed] Whats the STW mobile phone of choice these days?

My Moto G (bought after advice on STW!)has just passed its 2nd anniversary, and strangely the battery has just started playing up. Its also got incredibly slow at everything, but may just need a reset or something.

Anyway, although its been fine, I've always been disappointed with the camera. So I'm after something along similar lines that will take better pics, particularly in low light. I've had a look at the Galaxy S6 and Iphone SE, but would rather pay a bit less if something acceptable exists.

So, what do you recommend?
