Do you really need the phone? The dual core 240MHz ESP32 seems to be able to do the job at lower weight and power consumption.
Maybe the old phone is better used as a controller?

I find the phone appealing because I want try to make it somewhat autonomous, like im RTS games where you give a unit a command to go somewhere and it figures the path out by itself and avoids obstacles without direct input. The phone has quite a lot of processing power and sensors and IMHO doing it on board will be more interesting. Also, I'm not sure that the connection will be always stable and high bitrate make the drone a thin client.
