Ok so today I rooted my phone without trouble using AlphaRevX beta. I've had no trouble with the phone. Everyone knows that rooting voids warranty but I can take off my root without a problem. But I just noticed when I took off the back of the phone, I saw a little circle that says "VOID" (Located at the upper right corner of the phone). I had really never noticed the circle before so I'm not sure if it said that or not before. So does that mean my phone is voided of warranty and is that how Verizon or HTC checks besides the software?
