  • Do not waste your money.
Color: US
Phone does not have 512gb of storage, it has almost none at all. 1 app filled the memory. After about 1/2 hour phone stopped working and I have a "System UI has stopped" message so now I can not make calls or send texts. I will have to go buy another phone. It is also not 5g it is 3g. To return it will cost me more in postage than the phone cost so I am stuck with a bit of trash. Do NOT buy this!!! ... show more
