[Q] This game claims they found severe problems with Samsung gyroscopes! Is it true? topic

I am really confused when i see that this game, FlipMob is claiming they found that All Samsung gyroscopes are severely poor performing. According to them, LG, HTC, Sony and iPhones are way better in gyroscopes. Also this game is not working properly in Galaxy S5, whereas it runs awesome in my friend's Nexus 5! Is it true, what they are saying?
