My Qmobile A120 initially detect the SD card when I insert it but after some time a message of “unmounted SD Card” apears and it did not detect the card, please suggest the solution for it, ASAP. Thanks
The SD card slot on your phone is malfunctioning and you should contact your service center for the correction of the same. They may ask you to leave the phone for a couple of days, so do take a spare phone with you. They will replace the SD slot if required.
