This is slightly off-topic, so I hope no-one minds. I haven't got my p3 yet, because I don't yet have time to fly it, but I've just ordered a Google Nexus 7 tablet, since I'll need it anyway and I can use it straight away. I know nothing about tablets at all, and only ordered this one because so many people on this forum recommend it. What I'd like to know is, are there things you should do to optimise this tablet as soon as you've got it and before you use it? Are there a lot of useless programs already on it that I might be well advised to remove? Are there things I need to know about settings? Having never had a tablet before, and owning a PC that still runs XP, I'm way behind the curve, so I'd appreciate any advice people can give here. Also, I presume you can download DJI's Pilot App even if you don't yet have a P3, Would this be a good idea? Thanks.
