Chess Mobile App Submit Issues

Hi everyone,

I just recently downloaded the Chess.com mobile app, and started a few games of online chess. However, I encountered a few problems. Firstly, my phone is a Samsung Seek. If you're not familiar with it, it has 3 buttons on the face, a touch screen, and slides open to a qwerty keyboard. On most/many non-smartphones, there are two buttons on the face or on the slide out keyboard, left and right, which can control menu options on the bottom left and right sides of the screen. Of course, for the mobile app, these are needed to refresh, go back, and submit a move. However, my issue is that my phone doesn't have any of these two options. I've thus far found that the "o" key functions as the right menu option, but I can't find the one that functions as the left menu option, and thus I can't submit my moves.

Does anyone have a solution? Is there a way to make it so that I don't have to submit, thus skipping that step? Still, I might need to access the menu to draw or whatnot...... Or, if you know the key to use (I think I've tried them all,) then I'd really appreciate it. Thanks.
