I recently got my phone and updated it from PR1.0 to PR1.2 through Nokia Care, as the update was not available OTA yet. (Couldn't wait

Well, I'm experiencing the following issues:

1. Face recognition has started recognising faces, which is great, but when adding a new face and starting to type the person's name, it doesn't auto-fill/give name suggestions from my contacts as it did in the beginning, It only displays a blank block.

2. Messaging app sometimes only displays phone numbers, instead of my contacts' names, It stays like this until I merge the message phone number with the specific contact, even though the number is already saved to the contact's name.

3. Video playback is also jerky on my side, as reported by other users,

Has anyone experienced anything similar?
