I have 5 times in past 4 years. And each time warranty honour n I got free service. I have replace motherboard, replace battery, sim module, usb port . One time tablet even booting up with yellow triangle. I dont think I am the only user n quite several similar too. Note2 many users got motherboard replace foc due to hardbrick failed flashing
Depends how you present your case  . Be polite n dont condemn the phone. I m honest n always tell them phone is rooted first. However be mentally prepared warranty is always void . Try your luck claiming.
