    Hi folks,

    I'm looking at buying a Nexus 7 (2013)...either the 16 gig or the 32 gig, for use with the P3, including screen recording of the flights. I won't be using the tablet for much of anything else, it will mostly be dedicated to the P3.

    Question...

    About how big are the screen recording file sizes?

    Thanks...

    Huh? Okay, I'll state the obvious.... it depends on the amount of time you record. The longer the recording time, the larger the file.

    Normal is 650MB. But I have been having trouble lately with go app freezing when using screen recording. I used ez screen recorder without problem but after a while it started freezing and reboot. Switched to a screen recorder called Unlimited Screen Recorder and it was fine for a while. Then same thing happened. I have 9GB free on the 16GB Nexus 2013 on Marshmellow 6.0.1.
    Without screen recorder I have zero problems.

    depends on the app u use to record with but 16gb should hold at least 16 flights worth of footage.

    Trackman1...so you are saying that a "full flight" (15-18 minutes?), uses 650mb?

    Thanks...

    Trackman1...thanks so much for that...just the info I needed...OK...looks like a 16gb Nexus 7 (2013) will do fine for me.

    I appreciate your effort.

    Thanks...
