Friends do Not buy redmi phones .i bought mi 4a in april 2017 and it was in good working condition , after some days I realize the problems with its music player and till date phone is in the service centre . They have taken one week to detect problems and now they do not have a solution so they want me to stay calm till problem solve . Although , I have done many emails to xiaomi service support team , but this is my problem and I wish it happens with you.think before buying .the one problem of mi is the dual sim and memory card slot and heating problem and also service is not good otherwise is medium phone
