A:Answer The phone only has 4GB of RAM. This has been confirmed. Also, I don't know if it will work on Sprint's network, but It is not compatible with Verizon. I spent 1 hour with Verizon's tech support in trying to fix an issue on the phone where I was not able to make or receive calls. And in the end they said the phone is not compatible with Verizon's network. I even confirmed this by entering the IMEI number into the compatibility checker on the Verizon Wireless website, and it said it is not compatible.
