mine sits flat, and I can sure see both issues here, your phone should be cradled in your two hands typing with your thumbs, I just tried to do it on the table and it was typo city (mine DOES sit flat by the way). I also agree that yeah that phone warping is definitely and issue. Mine sits flat and it never gets torqued in any way. You don't perchance carry your phone in a snug hip pocket do you? That could warp the chassis over time, the battery cover is flexible enough to follow the warp. If that happens to be the case you're gonna eventually crack the display and touch screen as well.
