Love the number look up. But I don't like how it allows you to block numbers, but doesn't give you an option to unblock them. Nor does it show a record of blocked calls, like if you blocked a number and they were to try & call, no record of it. And with the spam filtering, I wished it offered you a spot to see the calls that it had filtered.

To see any number that you have blocked click on the Calls tab and navigate to Call Routing Settings. Click on my Block list. From here you can see all of the numbers you have blocked and if you want to unblock a number just click on the number and click unblock. To see the how the app filtered you calls go to the call log for details.

My chrome was hacked but before Google could let me know, this at&t active armour factory reset my phone when all I had to do was update my chrome and change a few passwords. I lost all my photos, a few contacts and my personal ringtones I kept from years ago. I've been paying just to see if it got better... Nope, I don't have signal 3/4 of the time cause of the VPN. When i shut it off it turns itself back on. I think I'm about done with it. Just a headache I don't need.

AT&T worked out the bugs & the app works really great. A lot of useful features to keep your phone & information safe. The VPN is really cool. When using an internet browser, a lot of sites use a location finder/tracker. According to the websites I am in, Ohio, New York, all over the country except for where I actually am.
