I had 2 different Nexus 7 2013 from Best Buy. Both had defective touch screens and awful battery life (less than 6 hours screen time) and I'm a very light user. Don't bank on Google fixing the problems.
Mine has slight screen lift and it creaks when you twist it.
Also the past couple of days it's been crashing, but I think it's an app that needs updating or the update is messed up. Booted into safe mode and it was ok.
Sort of bothers me, but not enough to send it in to Asus to fix.
I should have bought from google play store. Warranty work would have been a lot easier.
I don't think I will ever buy another Asus product. They had the same issue in the original Nexus 7. Surprised I have it on the 2013.
