I'm having an issue with my internet connection in general. No matter if it is WiFi, 3G or 4G. I will go to get on the internet and I will have no connection but I will have a blue symbol for whichever method I am using to get online. Sometimes I will have the WiFi and 3G/4G signal at the same time but no internet connection. It is sporadic but frequent and really starting to get on my nerves. Its been a problem for some time now I'm just now getting around to asking. I've tried kicking into airplane mode and back to restart the connections but that usually doesn't help. It isn't only with one app. Most frequently its FB and the browser (well that's what I use most obviously) but I have noticed it with some other apps as well.
