MiMacro is an automation task from Xiaomi like touch on MIUI Game Turbo. Has INTERNET and READ_PHONE_STATE permission allowing access to the phone number, serial number, whether a call is active, the number that a call is connected to... What is sure (from the code) is that the app collects the IMEI. Pithus analysis: https://beta.pithus.org/report/2b056ed84fe500552a58184035b962ba68af29457c24930c0aa8c9eba4af7bcf
