I have a Samsung S5 which I really like and really have had no issues. Recently I noticed that in the office, grocery store and even the gym, the mobile network indicator doesn't have any bars. I never really understood why, but normally I would turn the phone off for a few mins and the restart. In the office that solution works better; but in other locations, that solution doesn't work. At home, I have strong signals and a network extender so I don't have any issues. Internet connectivity and text messages are all fine during these time periods.
My question is there a general fix to this outside of doing a factory reset which I have seen responses to other people having similar problems? A factory reset is just a pain because you get your phone to the setup in a manner that you want and essentially have to start over with no reasonable guarantee that a factory reset solution will actually work.
