I;ve been using an android tablet- Asus tablet 8" was on sale for $138.00 at B.Buy & the sales kid is a drony, recommended it, & it works perfectly. That is, until I saw my neighbours P-4 with a 12" screen!
I have a Lenovo 12" tablet that my kids used for gaming, the one that has the round battery across one end, I will get the model #.
Cleaned everything off it, except DJI go & Litchi apps, my Hemmings car mags. & the thing is awesome!
Big bright screen, no lag, but, it doesn't quite fit the holder, I simply put the round battery end down, & use a 1" piece of gaffer tape at the top of holder. Not much of an issue, & to me anyway, worth for the wonderful, big bright, images!
I;m looking for a better landyard, as balancing is an issue & may be with any large screened tablet, I would think.
