I currently have a redmi 3s prime with eu rom and wanted to switch to rdmi 4 pro. Im wondering what are your thoughtsof the device: Is the performance or the camera better ? In this review it says redmi 4 pro eould lag in ui and games. youtube. com/ watch?v=OOftP5TC6qU Is this true, because i never experienced this kind of lag on my redmi 3s prime? Or is the lag only a problem of the chineese rom?
