Disappointingly, none of the variants include the option of a microSD slot to expand onboard storage, so the majority of the devices are limited to 16GB plus 7GB of free SkyDrive storage. This leaves it somewhat constrained in comparison to other devices.
The location of the charging slot has moved from the bottom of the phone (where it is on the Lumia 920) to next to the headphone socket on the top of the chassis for the Lumia 925. Volume, power and dedicated camera shutter buttons remain on the side of the handset.
The camera hardware is also mostly the same as the Lumia 920 (although it uses a 6 lens Carl Zeiss arrangement rather than a 5 lens) meaning that it has an 8.7-megapixel sensor with optical image stabilisation and dual LED flash.
Naturally, there's autofocus too and the ability to capture 1080p HD video at 30fps.
There's also a front-facing 1.2-megapixel camera for video calling or still pictures.
Many of the upgrades to the camera come in the form of software tweaks, largely delivered under the umbrella of Nokia's new Smart Camera mode/app.
Essentially, the app brings a host of new preset modes to the phone, such as Best Shot or Action Shot or the ability to remove moving objects.
Best Shot allows you to choose from one of ten frames taken for every photograph so you can select your favourite, or the most in focus, of the bunch. Similarly, Action Shot uses the same ten-frame approach, but allows you to select or deselect how many you would like to show to create an 'action' effect; there's also a mode that allows you to blur the background, or removing any moving objects from a picture.
