When I went to mtn yesterday I asked them for a mate 7, I kept on asking them if it is the 3GB ram version they said yes, today I went to get the phone and once I was done setting up I went to check what android version i have and to my surpise my phone has 2GB ram, is there anything I can do? As this is not the version of the phone I thought i was getting, can I do anything about this? Or am I stuck with it for the next 2 years?
