I have had my Samsung Galaxy S3 for about 2 weeks. durring that time i was always in 4g lte for the most part. now i only get 3g service when i was getting solid 4g lte. why did it work for 2 weeks then all of a sudden stop connecting in places i know have perfect 4g lte connection?
Mattyshore, I can see why you would be upset over suddenly not having 4G connection. Has your connection come back? If not, what city and state are you located in? If you haven't already, try removing your battery and SIM card for about 30 seconds and replace. If you downloaded any new apps, especially battery saver or antivirus apps, around the time this stopped working, please uninstall.
Let me know if you still need assistance.

4G LTE was turned on last Thursday where I live in the 49015 zip in Michigan. I can call and send text with low signal in 3g 1 bar (as low as -110 dBm) just fine in a big office building in their basement, but can not hold a good signal in LTE. I can walk down the street and get 5 bars (-78dBm) and walk just 300 feet more, and my signal will drop to 1-2 bars (-108dBm), or completely change to 3g, and yet my surroundings did not change. It is like this not only in my zip code, but all over the city and area in which I live. I have only installed the speed test app. Tried 2 different resets. Taken the SIMS card out. Been into the Verizon store and have also called customer support. I was told that no one was aware of any signal reception issues like this.
After talking to Verizon technical support about the issue numerous times, they decided I should try a new SIM card. And now, the phone works much better. Much better in fact, that in comparing to the Razr, the S3 phone has much clearer call quality, and even better signal reception, and higher upload and download speeds
I have been down that road as well. I had the sim card replaced a month ago now, and for a while, I was getting good signal strength both 3g and 4g. Now I am noticing a drop off again. I live 3 miles from a 4g tower and even outside standing in the middle of the street with nothing but blue skies over head, the best I can do is 3g for the most part.
Have had other issues that started a week ago If I hold the phone in the back with the bottom into my palm, the signal will drop. If I hold the phone at the top with my fingers holding the edges, which is awkward, or hold the corners with my finger tips, the signal goes up. (here is an example of 1 of the days)... When I held the phone at the corners with my finger tips, the signal was high at -89, and when I held it normally with my hand on the back, and bottom of phone resting in my palm the signal dropped to -105 sitting in the exact same spot without moving the phone around. This happens all the time. This has been enough of a drop, to be able to loose LTE in locations and go into 3G. I have called Verizon about this, was told it would be 2 days before they could get back to me about this problem. A note was being sent to a technician where my issues would be looked at. It has been almost a week, and I have not heard anything. This started happening last week with the update that came. My weather widget had a grey line at the top, and my screen was freezing on phone calls. I was told to reset my phone. After resetting, those 2 issues cleared up, but then I had problems with the signal issues.

From the Verizon GS3 manual:
Note: Your phone’s internal antennas are located along the top
and bottom of the phone. Do not block the antennas;
doing so may affect call quality or cause the phone to
operate at a higher power level than is necessary.
From Samsungs GT-I9300 manual:
Verizon tech support helped me today. So far I have been satisfied with Verizon regardless of any phone issues. Everyone has been very nice and helpful. And thank breezex and others for your input. I will be sent another phone to see whether these and other issues still occur, and I will post as to what happens... thanks again!
