ISSUE WITH MERGE OF NON IDENTICAL CONTACTS IN ANDROID


   QUERRY:     

               Auto Merge of contacts that have no relation to each other. Even we cant separate it by               editing in phone.





    ROOT CAUSE:  

  • It was a software bug in android OS or may be a 3rd part android APP which you are using for restoring contacts from .CSV file. 
  • I tried importing contact from back up, each and every time i restore my contact, non identical contacts are merging automatically. This happens randomly and not same for each time i do.
  • It was a software bug so we cannot identify what was exactly causing this issue.
   SOLUTION:

      Step 1:   Sync contacts to Google
  • Sync all the contacts to google account.
  • By default it will done daily. Still do it once. 
  • Go to setting in Android. Select Accounts and sync, Select Google account, make sure sync was enabled for contacts sync. Click Sync now.
     Note: There may slight change in setting menu depending on Android OS version for contacts                       SYNC

       Step 2 :   Identify duplicates if any.
  • Login your gmail account and select contacts tab. Select duplicate contacts.
  • As i tested in many ways, merged non identical contacts will not reflect in google account.
  • Identify and merge duplicate contacts if any.
      Step 3 :    Clear Contact Storage in Android
  • Go to setting and select APP. Select Contacts app.
  • Select and clear Data of contacts.
  • Turn off internet before clearing contact storage.
      Step 4 :   Sync contacts
  • No turn internet on and sync your contacts back for google.
  • Sync will be auto done when you turn on the internet.
  • You may get notification that Too Many Contacts deleted, Select undo the delete.
     Done. You will not find any non identical contacts that are merged earlier now.

   PRECAUTIONAY:
  • Never restore .csc directly from android OS. 
  • If it is really required to restore from .CSV, restore it to new gmail account then sync it back to your Android phone.
