I have an S5 with 1GB data plan.
Wifi works fine, but I cannot download apps, watch a youtube video or anything else with a Wifi connection.
I can do basic internet searches, but if I want to say watch a video, it says connection to server lost.
If I go to the play store, it says that I must enable background data.
No problems at all on Wifi, but very frustrated.
Any ideas?
PS - I do not have "use only Wifi" selected.
