Yeah i know this is sad but i play alot of games on my phone when i have free time what can i say i am a gaming freak..
i have a tip for you lol but you have to know how to do stuff... Basically you can use root explorer or root browser and browse to your build prop file. This is located in System folder then open the build prop file with text editor.. and locate these lines..
at the end of these lines after the equal is your region. Your in brazil
so i am guessing your one will look like this
Change yours so it looks like this
and then restart your phone and download your game for free after your done. redit it to the original.. and your done..
