I have galaxy 21 ultra with Verizon for six months the phone crush 2 times I lost all my data, wright in the middle of doing something it shuts down and reboots it self for no reason. I went to Samsung repair center and the told me the motherboard is faulting, and it has to be repaired by the factory, they told me to send it to Texas, I ask them what am I supposed to with out a phone they is nothing they can do about it. I call Samsung Customer Service And they told me the same thing. All my electronics and appliances are Samsung because I believe in their Brand NEVER AGAIN!!!!!!!!!!!!!!!
