And by the way, doesn't address directly to moderators here.
First, moderators are only community/forum moderators, they have no power on courses or lessons.
Second, the author of the courses won't read the things people ask here, it would be impossible, and this forum is only made for the help between users, about the lessons, grammar and vocabulary.
To send suggestions or improvement requests, you have to send the form, or click on the report button.
I'm more confused on why Tom is spelled in english but Tim is spelled differently I am a bit confused. As an american I am not exactly sure if this is how in Russia it's spelled but for anyone who is native Russian is certain words spelled english and some not? (Or is Duolingo just trying to help make it a bit easier?)
Any phones can type any alphabet, just go in the store. I downloaded SwiftKey for instance. I went in their settings and downloaded as many keyboards indifferent languages I wanted, including Russian. It has even an integrated translator in addition, and you can use Russian and English at the same time!
