My biggest beef with my S4 is that I lose my internet connection all the time (when I’m on here, but I repeat myself) and the pages won’t load. I have to turn airplane mode on then off again. Probably do that 10-15 times a day. Very annoying. I figure it’s a bit of planned obsolescence meant to prod me into buying a newer version, but I don’t have a need for anything beyond what this phone offers, and planned obsolescence pisses me off.
The airplane mode trick forces the phone to relink with a new cell tower. You have a bad cell tower near you with a broken router. It’s not your phone.
