Do Not try Unknown APK of Pokemon Go

• I know It's a little bit late, but I would like to suggest you not to download the APK file from any unknown website. Let the game come to Playstore of India. Just becuase the Game became viral, many people of INDIA are downloading the APK from different sources. 
• I have checked some APKs and those are malicious. It may harm your phone or simply control or steal your important data. 
• Solution: If you really want to play, You can use BlueStack player on your PC.
