This started after cllearing contacts cache. The contacts storage was moved to SD card earlier with links2sd. Cannot find contacts storage on my phone now.

I have tried factory reset, clearing contacts cache etc. . Nothing is working. Dont have any contacts on my phone now and neither am i able to open contacts. The acore message keeps popping up !

Somebody please help !

It's strange that this persists after a full factory reset. I would remove the SD card, in case the contact data on there is confusing the system, then try another factory reset.

It may be an app. I removed the Facebook client and the android.process.acore error stopped.
