memory card issue

[krb1996]

Hi guys...I'm using a sony xperia neo v.Suddenly my phone has got some memory card issue..don't know y or wat. It keeps showing memory card not inserted or damaged always ...suddenly it'll work for a minute in like 10day but at that time phone becomes very slow...I tried factory data resetting the phone....it has 4.0 Android ...I also tried formatting the memory card many times but no use...

Could be a faulty card or card reader IE the contact points - You could try a different card which would show one way or another what the issue is - if it's the card reader then this would need to be inspected by a service centre - http://www.sonymobile.com/global-en/support/contact-us/
