On my old phantom 2, I could use my Asus transformer TF700 tablet instead of my smart phone. But since it does not have an USB connector, I don't think I can use it on my P4. Can anyone suggest a tablet that is not over 6.5" wide with a USB connector that I can use on my new phantom 4? If possible, something that really stands out in sunlight. Most smart phones suck in sunlight for flying these things. Thank you
