After updating to the Kitkat update on my S3 I have seen many issues with my phone, mainly 4G speeds and GPS issues.
My 4G speeds in known good places I frequent dropped after the update. GPS will rarely find my location now in Google maps, or other apps attempting to determine my location, this is with high precision on and it doesn't matter if I'm in a wide open field, this worked perfectly before.
I have called Verizon at least 5 times now and they always come up with something new I need to try to see if it fixes this issue and of course they always throw in "sorry your phone is out of warranty". Well why would you release an update that breaks a perfectly good phone, I guess when the warranty is out on most of these S3's why care, this is the attitude I feel Verizon has about the issue.
So now I'm stuck with a half working phone due to Verizon's worthless update! Thanks Verizon for standing behind your product, the KitKat update.
