Hey guys, I bought a Samsung Galaxy s3 from Verizon two weeks ago and I've noticed that whenever I dial a number which then requires me to pick an option and press additional numbers the screen starts flashing on and off so that I can't even dial. Today I called the 800 number for my insurance company and was asked to dial 0 for customer service but the screen was flashing so fast that I couldn't dial the 0. I ended up hanging up and using my husband's Droid to make the call. Has anyone had this problem? I don't have notifications, emails, texts. I have only downloaded some basic apps and the phone is fully charged. By the way, I should mention this is my 2ND Galaxy s3 in two weeks. The first one died after one day and I had to go get a new one.
