It could be a firmware issue, but we won't know that until we get similar reports.

So in the meantime, ensure you had a clean install.
Best way of doing this is to connect to Kies and use the Tools > Upgrade Firmaware and initialization option.

But backup your data first.

My wife's phone has the same problem when updated via OTA to this firmware. I also tried clearing the cache and resetting the phone but the problem returned. I'm thinking of flashing a firmware from another country via Odin. Will this solve the problem?
