Whenever I watch YouTube videos on my DNA the videos buffer and buffer while the phone is on WiFi even when I switch the video out of HD. I'm running off of Verizon Fios using the Verizon modem/router. My desk top computer which is hardwired in the modem/router works good and the download speed is around 80mb and upload of 65mb. The phone is showing "excellent" strength for WiFi and the download speed on my phone is 33mb and upload of 51mbs. When I switch to 4g instead of WiFi I can view videos a bit better but still out of HD. I don't understand why it buffers this badly. It didn't buffer this bad when I had my old Samsung Galaxy S with only 512mb of ram. Any suggestions??
