Does anyone have any suggestions for budget 5.5 to 6 inch phones that work well for DJI Go and the Mavic specifically? Anyone use any of the budget Chinese phones with international firmware? My iPhone 6s is too small to use for DJI Go with these old eyes and I don't plan on upgrading for a while. I hear that the Nexus 7 (2013) chugs a little bit and I'm not sure I want an iPad Mini. Thanks in advance.
