If you're going to fork over a decent amount for cash for a tablet like Google's Nexus 7, then it's probably wise to pick up a nice case to ensure it stands the test of time, right?
Well in the case of Google's official folio case for the 2013 Nexus 7 might be doing more harm that good.
An Android Central reporter who grabbed the red iteration of the case when buying a Nexus 7 three months ago, took it off recently to reveal rust-coloured line all the way around the edges.

Around all four corners and everywhere there's a cutout on the case, a deep red line on my otherwise pristine black Nexus 7. I can scrub all I want, and the lines don't seem to want to come off," wrote Andrew Martonik.
Not a cheap option
The official folio case is by no means a cheap knock-off at $50 (£30), but it's the open backed design that's likely cause for the stains.
The case, which also comes in black for those unwilling to deal with the red stains, has wake/sleep functionality and folds back into a number of positions.
So, we're not sure if there's a moral to this story other than to say even supposed protection can be damaging for your gadgets.
