It used to be really good but somehow as the days pass, it is really using a lot of memory or RAM. When I try to chat-in game, it is slows down the game and causes some games to crash. I confirmed and at the time when my game was using 49%, this keyboard decided to use 12% and that causes the load 98% ram usage. Why does a keyboard need ~12% RAM in the background when I'm already doing an intensive task. And my phone has 6GB RAM and it should be enough. The least RAM used by it is ~200MB.
