I have successfully loaded google play store Litchi Drone Deploy I can not get google play services to run right which is what both of these 3rd parties are asking for me to run and I keep getting an error message telling me google play service has stopped working. this is on a p4p + as well and just like you I loaded it with .apk but I loaded it directly to the controller and did not use me PC. Have you had any further luck with yours I've had this for 8 months and I would like to start taking it to the field and helping do my job like i intended it to as as opposed to just using it as a hobby
