I had no issues the day I bought my phone to but I did something stupid, I went to verizon to ask what else I could do about the battery lasting longer, the tech said "oh wait you have a bad charge port" let me send you a new one, I told him I just spent 250 & do not want a refurbished. He swore I would get brand new.. Nope I got a damn refurbished & have has major issues since.. The constant rebooting, texts going to the wrong person, freezing & whatr ever else I can't think if. Since I know nothing about computers I wont root my phone Cuz I know I will destroy it. On my 6th thunderbolt since I got my first the day it came out & I swear they get worse each time. So patiently waiting for the ota upgrade.. Grrrrrr
