Since receiving my P3P, I've been flying using a nexus 7 (2013) LTE, and I've had the same problems reported by other people...usually meaning that the app crashes every 2-3 flights, & the video feed is slightly choppy. As many others have discovered, just because a device isn't on DJI's "approved" list, that doesn't mean it won't work. Case in point: Asus ZenPad S 8.0
I recently purchased the just-released Asus ZenPad S 8.0 (currently only available from Best Buy, although others (B&H Photo, Amazon, etc) are taking pre-orders, & should be selling them soon), and while I've only used it for a single test flight, I will state that I encountered no problems whatsoever. For those not aware of the ZenPad S 8.0, it's among the first Android tablets to be running a 64-bit CPU. It's overall specs are considerably superior to the Nexus 7 (2013), and having compared the two tablets against each other, using the Android versions of 3DMark & PCMark, I can confirm that the ZenPad S 8.0 does, in fact, outperform the Nexus 7 (2013). One of the best selling points of the ZenPad S 8.0 is it's price...only $199 for the 32GB version (at the same time, I don't know if this is an "introductory price", or the permanent price).
It will be at least a few days before I can get in extra flights using the ZenPad S 8.0, but once I've got a few additional flights using it (still under the DJI Pilot app, unless the Android version of DJI Go gets released before then), I can update this forum regarding any problems discovered, if there are any.
