Through research I have seen that a number of people have had this problem, but I couldn't find a solution or anyone that solved the problem so bare with me if this has been covered... I have a Galaxy S3 (my wife has the Galaxy Nexus and has the same issue, my daughter has an iphone and has no issue) We have connected to our wi-fi router (Comcast/Xfinity) for over a year with no problems. We have a Smart TV as well as a laptop that connect and perform with no problem whatsoever. The phones have also worked perfectly as well up until about a month ago. I noticed that photos weren't loading on Facebook or Instagram. Then Facebook wasn't updating all-together. My husband was having the same issue. Now just about all apps that require a refresh or load do not work or take an extremely long time to "catch up" I have been in contact with my internet provider who sent a refresh signal to the router and instructed me to unplug and plug it back in. No help. I spoke to the Verizon Wireless support who had me do a factory reset on the phone. No help. I have also tried a few random things that other posters suggested on the forums and no luck there either. Both phones show a strong and full signal for wi-fi and as I stated all other devices working perfectly. Has anyone come up with a reason or solution to this problem? Thank you in advance. T.S.
