Phone not dailing/texts not goin

[Katheryn Caras]

Why, after updating the AT&T software, keeps freezing. Is this a software or hardware issue going on with the phone.

First, try booting into Recovery and wiping the cache partition, which won't erase any personal data: Reset: Samsung Galaxy S 4 | T-Mobile Support

If that doesn't help, then bring your phone in to an AT&T store and see if they can help. If their update caused the problem, then they need to fix it.
