Before my GS3 updated to kitkat my apps would crash all the time. My phone updated last week and now the apps work but in what used to be areas with strong steady 4g coverage I have no data. So annoyed. I can turn my data on and without touching it I'll have 4g for a minute and then none before coming back for 5 seconds only to go out again. What am I paying for? My office doesn't have wifi and I have a large data allowance but what is the point if I can never use it? I do a lot of travelling and use my phone as a GPS but as I have no no longer have reliable service anywhere even in Philadelphia where it was a constant 4g. Not to mention the GPS is unreliable as well. Waze is an amazing GPS but to have a phone that doesn't work half the time is frustrating. I should just go back to my old flip phone that lasted me 2 days on a single charge. My phone is due for an upgrade in a few months. Maybe I'll save some money and get something that isn't a smartphone and I won't have to worry about paying for the data and everything else that comes with having a smartphone.
