*kicks things* (also I feel like I've asked this before?)

I am wishful of a new phone:

* running Android 5.1 or newer
* unlocked; I should be able to transfer my existing mini SIM (which is Tracfone, which is AT&T compatible) and microSD cards with no problem
* with enough internal storage that it won't have fits at me when I try to update apps even if it does insist, as the existing piece of shit phone does, that apps go to internal storage first even when default install location is the SD card (and I'd really rather it didn't so insist)
* not fucking costing an arm and a fucking leg
* has a headphone jack (because apparently I have to specify that now)
* bonus points if it's dual SIM such that I can insert a European-network-compatible prepaid SIM card for my hopeful trip to Greece this December

What brands / models might people recommend?

( in which I poke reviews and purchase sites )

But if I can find something under $100 that would be marvelous.

Poking about Amazon, Samsung Galaxy J1 Mini looks pretty good and it's $77.

ETA: never mind this, it's less hassle just to do the bits in italics

Okay. I'm working through Guido Henkel's ebook formatting series and there's bits in this short story where, if the ereader default font is serif, I want these to display in Verdana or other sans-serif, and if the ereader default font is sans-serif, I want these to display in Garamond or other serif. Think I can do that? How would I do that?
