Thank you for reaching out to us. Not being able to make a call or having the device freeze is certainly annoying. I understand fully. Let’s see what we can find out about this.
First, let’s check out your area to make sure there aren’t any contributing issues going on there. May I have your zip code and two cross streets? This will allow me to check to see if any tower work is contributing to the connection issue.
When the device freezes, are you doing anything specific? For example, charging it, trying to access the internet, texting, etc. Has the device been rooted?
Let me know and together we’ll get to the bottom of this.
