DNS error in android 4.4.2 I just get an new mobile Samsung Galaxy S4 GT-I9505 with Android 4.4.2. 

When I try to connect to internet through 3G/4G network, my Chrome always give me an error message:

DNS_PROBE_FINISHED_NXDOMAIN


The internet can be accessed by IP address with the same network.

How should I fix this problem?
My problem is solved as I install avast firewall and need to enable linux shell to access mobile data.
