Samsung Galaxy Note3 is a big phone, but not a big phablet. Fits a normal shirt pocket in an otterbox comutter case.
I liked the more flexible tmoblie, N900T version. Replaceable battery and takes 64gb microsd on top of 3gb ram and 32gb. Runs Avare in portrait mode. Bluetooth link to dualgps170 for adsb-in and another great gps source. (Stratux dual band should be better for half the price). Plays music out the stereo jack. It does not rapid or wireless charge. It draws 1.5 amps max, and about .4 amps when charged. Just barely fits a standard Ram X mount.
Using Android 5.0 something, usually has about 1.5gb free RAM. Avare is up to 8gb of data each 28 days if you load most of USA charts and plates and A/FDs.
A usb charger converted from the old cigarette outlet keeps the phone charged.
A 4 port USB 12 volt powered hub charges the dualgps. The squarish port feeds the adsb to the GRT usb, another slot holds the memory stick for the GRT logger and database transfer/update. A port alsk powers an LED gooseneck light.
New old stock from auction site under $300, unlocked. I don't like current phone price schemes, I keep an older free rollover doubled data plan with too many geebees. Squaretrade is a good warranty option if desired.
A 7 inch 2GB RAM 32GB tablet is fine for under $200 if you have the space and don't want or need a phablet sized phone.
