User complaining of Android app 'disappearing' following an update
<p>A user of one of my Android apps has reported that his version 'disappeared' following an update. None of the other (thousands of) users have reported issues.</p>

<pre><code>This morning I tried to open up the app but could not get anything. 
I tried and tried and then physically turned my phone off and back on. 
Now the icon has disappeared.
</code></pre>

<p>He has a lot of data stored in the app, so removing and re-installing isn't an option.</p>

<pre><code>I think the problem has been caused by another apps update which happened yesterday. 
I can see your icon in my apps list but it is the only one that is black and white, all the rest are in colour.
When I view the properties of your app it says: 
Storage 20.00KB
Application 0.00KB
Data 20.00KB
It gives an option to clear data or uninstall.
My memory card, which I haven't removed, says I have 55mb of data left.
</code></pre>

<p>What could have caused this, is there anything I can do to avoid this happening to users in the future and is there anything I can suggest to remedy his problem?</p>
