Xperia U can't restore contact using Backup & Restore app

[druk]

I made two backups using the preinstalled app: Back up & restore on my Xperia U. After resetting the phone I'm unable to restore contacts though apps and SMS restored successfully. This problem exists with both the backup files. I also tried restoring only contacts but only 5 contacts got restored.

When I restore using "Back up & restore" app call logs are restored succesfully and when I open the contacts I can see all the names in the call log then suddenly(within 1-2 seconds) they start disappearing and get replaced by that contact name's number...i.e. after restore is finished if I open Call logs all names appear in it like:

Alexander Smith

Mobile +923341000

William Toad

Mobile +923341000

Narendra Kumar

Mobile +923341000

then suddenly call log appears like this(see below) and all contacts disappear except 5 contacts:

+923341500

+921341099

+928341000

Sorry I couldn't provide screen-shot because transition is so fast that I'm unable to capture it.

Thanks

or is there any way to read the "com.sonyericsson.android" file in ".semc-fullbackup" folder because this file contains all my contact backup...even if I could read this I would manually restore my contacts.

Thanks

I also have had this problem recently and all my contacts keep disappearing in the call log after restoring backup. Please Uliwooly could you explain in clearer words, I can't really understand what you posted. Thanks in advance!!

@Bayo

Open the phone app on your phone, then check contacts, menu amd check the filters
