How to cancel the dialing of Samsung mobile phone?

If your phone doesn't have a dial key, we suggest you try the following methods:

1. Standby-Applications-Settings-Application Manager-All-Mobile-Clear Data

2. Back up data (contacts, text messages, photos, etc. ) and restore the factory settings.

If the problem still exists, it is recommended that you take the purchase invoice, maintenance card and mobile phone to the local Samsung service center for professional engineers to help you test.
