You may need to move some apps from your internal memory to the SD card. &nbsp; Drilling down to the properties of the app itself (in the app manager of your device) should allow you to do that.

Yes I did that but shouldn't new app be installed. &nbsp;I thought that formatting the card as internal storage would mean that there was one big drive. &nbsp;When I run some storage analysis apps the space is listed as one big drive with loads of space left.

&quot;<i>Yes I did that but shouldn't new app be installed [to the SD card automatically?].</i>&quot;<br />
Not automatically - at least not on any Android device I've used.<br />

No.

This is a new feature with marshmallow
</div>


<div>
It also states that the SD card will become the primary storage.
</div>


<div>
Yep! &nbsp;I learned something new. &nbsp;It also states internal storage &quot;disappears&quot;, which is why you can't see two different stores. <br />
<br />
How big was the SD card you installed? &nbsp;How big is the app you're trying to download but can't?
</div>


<div>
I not expecting to see 2 different stores. &nbsp;I expect one and I see one. &nbsp;I see 12gb free space. &nbsp; Even small apps won't install. &nbsp;I have moved all tge apps I can to SD. I'm got try a new SD card.

I upgraded to marshmallow and found the feature to format a USB card as internal storage. I did this as I was running low on space. This seemed to work fine. The extra storage space was showing up. However when I try to install an app it still tells me I don't have space

Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android's user interface is based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input. In addition to touchscreen devices, variants of Android are also used on notebooks, game consoles, digital cameras, televisions, automobiles and other electronics. Applications are usually developed in Java programming language using the Android software development kit (SDK), but other development environments are also available, including Delphi, Ruby and Visual Studio (using C++).
