I think zopo color M4 is a bad phone it does not have any thing intresting in it. On my opinian onyl the operating system is somewhat updated otherwise all the other features and worst. I have buy this phone for my mother and now we are not happy with the service of the phone. The phone have only one gb RAM which is not good in todays world. Camera of the phone is also not good. I also get the heating issue from the phone and phone hangs very time. Sound system of the phone is also not good. But is the phone is of low price. I think it is waste of money.
