Hello. The USB port on my Nexus 7 is loose (I have to keep pressing down on the cable for it to keep chrging). I have been thinking about sending it to Asus for them to fix it (still in warranty period), but then I realised that root supposedly voids the warranty. So my question is, will they fix physical parts for free because root is not what caused the problem? Or does root void all warranty? I know they charge incredible amounts of money if it turns out your device is not under warranty.
