Ashley, please, reconsider the issue.
It's very frustrating to talk in english, because I can't express or use all my knowledge to make a phrase covering the issue as I like.
Well, trying again. The issue is affecting my game in many ways, but it's hard to see on the first time and need attention to the details.
Here is a screenshot showing the issue and upper and on the bottom is how it's right without the full screen, even using the scale outer.

Also, as I said, this game will be published on Androids, and I'm near to the publishing date, but, unfortunately, when exporting to the CocoonJS, the issue of misalignment return, even using letterbox scale, scale, scale outer or any other method, but there, on Android, the font create a line on the top of each letter, with approximately a half pixel, like the image above, but on the top of the letter.
If necessary I can search for a program to take a screenshot of the issue for you, but I can't stay with this issue, because it's affecting negatively the quality of all the job with an unprofessional polishment, where I'm incapable of solve.
So, if it's looking right and is on purpose, it's worse than I was expecting...
Why wait, here is the APK, you just need to use it with the CocoonJS Laucher App
