I know one can use U-center to configure the F9P but is there an app to do it with android? I would like to be able to change the update rate in the field.
Thanks.

Hi, depending on the app You are using to connect to Your F9P, You could send UBX sentences as startup messages to change the configuration of Your module. I used this way to configure a M8T using RTKGPS+ or NTRIP-client for MapitGIS on Android. You may find more information about it on rtklibexplorer.com.
