signed apk behaving weird
<p>Recently I developed a launcher app for a Samsung tab 2 running android 4.0.3. During development/debugging everything was running fine. But when I created a release/signed apk we started experiencing problems with font rendering and the system home button not behaving properly.</p>

<p>Tested it again on the same tablet upgraded to 4.0.4 and everything was fine again.. can anyone tell me why?</p>
