The office writes apps so I get almost any phone I want. I carry a LG G4 and it's very nice.

I also have the iPhone 5S, some BLU 99 buck model that at 6 inches is a Phablet and nice.

Not only that but at home we have the usual Kindle Fire so you may want that for the price. Not to mention a Nexus 7 and an iPad Mini.

So if I had to downsize I'd keep the LG G4, Fire tablet. If I had a tight budget I'd look at the 6 or 7 inch BLU Phablet.
