HTML

<div class="outer">
    <div class="inner">According to a new report from AnandTech, Samsung might be fibbing its way to more favorable Galaxy S4 benchmarks. Has your device suddenly come to a crawl? Of course it hasn’t; benchmarks shouldn’t change your perception of a flagship as powerful as the S4. Still, it’s embarrassing that Samsung would resort to such technical tactics, like allegedly using code dubbed “BenchmarkBooster.” Yes, your device takes steroids.</div>
