Fine on iPhone, bad on android – LetterSchool - Block Letters Review

I got this app for my oldest 2+ years ago since his school was using it. He loves it, I love it. As long as it’s on my iPhone. Now his little brother wants to use it, so I put it on my Nook. With rotating locked, the screen will flip nonstop, frustrating us. Please fix this bug before I delete it!
