I was using both sim and sd card on my device from last 6 months but This new update which came out yesterday is such a shit that now i can not use both sim and sd card together, it says " there is something in the sim tray which shouldn't be there kindly check the sim tray and try again" this message is on the screen as the phone switched on after the update and none of the keys work. When i removed the second sim all is fine again..... this update sucks, 😤🤬🤬🤬😡😡 Can anyone help me how to rollback the update...🤔
