    I get that error on my Lenovo A1 EVERY time I try to click on any of my contacts. I’ve tried that solution… and 7 others. Clearing, reboot, syncing, unsyncing, etc. Same error still happens.

    This didn’t work on my S3. I’ve tried a factory reset. I can’t access the phone, or contacts. All messaging apps were crashing. But Now I have no apps.

    This worked beautifully on a Samsung Galaxy Prevail. I had this error several times before and went to the reboot. This is much better. It took longer to find the sync contacts button to restore.
