Hello guys I would like to ask you guys about GUID and IMEI. 1. What is GUID and IMEI? 2. Which one should i change in order to "be different mobile device" 3. if you change mobile device model will IMEI automatically change? or do you have to change it manually? I got really confused with these because i see GUID, IMEI, mobile device model in bluestacks. thank you guys in advance!!
