Is there a way to get the font on my phone onto my tablet?
A pre-answer note, I'm typing in the mobile Stack Exchange app, so please excuse any spelling errors.

Yes, there is a way, but it requires your tablet to be rooted.

As with most things, go ahead and take a backup of both devices, you never know what could go wrong.

OK, lets begin!
In a file manager of your choice, head into /system/fonts, on the device that has the font you like. This does not require root, because your are only reading from that file, not writing. 

Find out a way to copy the font file to your tablet. I would recommend just emailing the font file to yourself, and downloading it from the email onto the tablet.

Now on the tablet, rename that font file to something memorable, like goodfont.ttf. You are going to have to sacrifice the current font, or you can take a backup of the default font file. (If I'm correct I believe it's Roboto-Regular.ttf, but it might be different on yours.)

Now copy goodfont.ttf into /system/fonts (remember, this is on the tablet), and rename it goodfont.ttf to [default font name here].ttf.

Hope I was helpful!
