Chinese MIUI Firmware message upon start

I receive the message "Chinese MIUI firmware often limits work of lucky patcher in the back-ground. Because of this, Inapp purcase emulation and other functions do not work. Open lucky patcher settings to enable all possible permissions for it?". Following the message I have the option for Yes or No upon which if I press yes it takes me to my phones battery saving settings? I have enabled all possible app permissions and my phone is a galaxy s7 from the UK/England so I have no idea where the chinese MIUI software has come from. Lucky patcher/in app purchases worked previously but now they don't. I would appreciate any help. 

Sharing is caring, show love and share the thread with your friends.
