I recently bought a Samsung Galaxy Centura with prepaid Straight Talk service. The problem is my data connection is slower than what it should be. I get 3g with full signal in my area, and it downloads at an average of only 15kb/s. My previous phone through Straight Talk was a Samsung Galaxy Proclaim, a much similar phone, and it would download at 100kb/s in the same area with 3g as well. I rooted it and changed the DNS to GoogleDNS and its not showing any real difference. Something seems not right about it. Any tips? Are there more effective DNS servers that I could use? Thanks for any help.
