Samsung's Galaxy S7 and S7 edge smartphone is missing a major new Android feature.

There's no doubting that Samsung has pulled another beauty from the bag with its Galaxy S7 and S7 edge .

And the South Korean firm's all-new devices tick a number of wish list items, including a water resistant design, always-on display, better camera and, most importantly, expandable storage via microSD card.

With the return of this storage slot users can boost their phone's memory to a whopping 200GB.

However, whilst this is clearly welcome addition to the new phone Samsung fans will miss out on a key new Android feature called Adoptable Storage.

In Google's new Android Marshmallow operating system the clever new feature merges the internal storage with the microSD card, so it shows up as one save location.

For example, plugging a 64GB microSD card into your 32GB smartphone won't add a new storage location with 64GB of space – it just makes it appear as if you have a device with 96GB of free memory.

Unfortunately for Samsung fans the firm is not supporting Adoptable Storage with its latest smartphones.

The South Korean technology firm told blog Phandroid that it dropped the feature because it didn't want to confuse users who might remove the microSD card when the phone is in use.

With Adoptable Storage – because the memory on the card is seamlessly merged with the internal storage – this can play havoc with your apps and saved data .

Without Adoptable Storage, Samsung Galaxy S7 and Galaxy S7 edge owners will have to juggle two separate storage locations, internal storage and the external microSD.
