Hi,

I'm sure you have all seen the "what phone shall I buy?" posts. Well, I'm having a bit of trouble working it out for myself.

Both the screen and speaker on my Galaxy S5 are dying, so I thought that it's time to upgrade.

Required:

Network access on 2degrees NZ, Australia Optus, Japan (network not chosen yet - on holiday next year)

Android (prefer a recent version)

Similar size to S5, and must match or exceed performance

Dual sim preferable for travelling, though not essential

Expandable storage essential if internal is less than 64gb, but still preferred regardless

Bluetooth/WiFi etc...

4G LTE is preferred

Ideally $600-$800 range, but flexible for the right specs

I'm not too worried about camera specs, fingerprint readers, NFC etc, provided everything else meets what I want. I am happy to look at the new Chinese brands coming in, provided that they are of similar quality. My preferred retailer is PB Tech as I get quite a reasonable discount through work, but will go elsewhere if it suits.
