So you're using a existent pcba that already exists in some phones out there, for cost saving. Makes sense.
So the new Lauta is going to be a mid, high or low end ? Have you decided what OS will have ? If you go with mainstream android, how much of a trouble would be in terms of logistic, to sell a Sailfish version with official support (assuming that Jolla does the port) ?
