Is Build.DEVICE constant for the lifetime of a device?
<p>I'd like to (loosely) tie a file to a particular device, looking for some identifiers that are static per device:</p>

<p><a href="http://developer.android.com/reference/android/os/Build.html#DEVICE" rel="nofollow">http://developer.android.com/reference/android/os/Build.html#DEVICE</a></p>

<p>I'm hoping that:</p>

<pre><code>Build.DEVICE
</code></pre>

<p>is constant? For example, no system upgrades or hardware changes would modify that value?</p>

<p>Thanks</p>
