I was running a rom called neat rom and decided to upgrade to CM 10.1 after I upgraded I noticed some of my contacts were gone because I did a wipe. I realised that the contacts that were gone were saved onto my phone and not my google account. I tried checking my gmail account and using the restore contact feature it didn't work as my lost contacts weren't part of my google account. Is there anyway to retrieve contacts that were stored on the phone after a wipe?
