The phone will remove the home button of its predecessor, the excellent Z2 Play, and as such is likely to feature a display larger than the Z2 Play's 5.5-inch one. There are also some dual cameras on the back of a render that was tweeted by frequent tipster Evan Blass. It also seems the headphone jack has been removed.

If it's any consolation, it does look like Moto Mods will stay. Fans will still be able to switch things around -- literally -- and customise the phones with the firm's interchangeable hardware modules, including JBL's snap-on speaker.
