I got my S3 yesterday. So far it's not crashing like this but I can crash the phone with Chrome consistently by opening up an incognito tab, going to my gmail account, and trying to read any email. Causes the phone to freeze and eventually reboot every single time.
I've about had it. This phone replaced a Droid X2 that was crashing 3-4 times a day, and it was replaced on Verizon's dime. I had a choice between the S3 and an iPhone 4S. I have 2 weeks to switch, and given what I'm reading here, I am about to do it. I love the S3's screen and features, but I cannot live with a phone that crashes and reboots frequently...
