Problems with 4G dropping are widespread and there are posts all over other forums about it. A few people have contacted Verizon and say that they were told it's a known issue, even for people in a strong 4G area.
I'm experiencing it myself and I'm in what should be a strong 4G area according to Verizon's maps. Most of the time, I'm dropping from 4G to 3G but have also seen it drop to 1X. When I'm home, I'm almost always in 3G but also drop to 1X once in a while.
I've changed the setting so that my phone uses CDMA only and have had a rock solid 3G connection since. Sure it's not as fast as 4G but it's not really affecting my enjoyment of the phone. I'm gong to give Verizon some time to work out the bugs before I switch back to letting the phone auto detect 4G and 3G.
I'm in an area now designated as "4G LTE Extended Coverage Area" one block from an area designated as "4G LTE Coverage Area". In the 3G coverage map, I'm in the middle of a large 3G service area.
When 4G was announced in this area of South Florida, the entire area was identified as 4G, with no mention of a distinction called "Extended".
My experience at home: I get no 4G LTE service, usually no bars, and intermittent 3G service.
Trips deep into the area designated as "4G LTE Coverage Area" on the coverage map yielded mixed results, with several locations showing no 4G LTE service.
Verizon says they surveyed my street in response to my report and said all service was indeed "marginal". They suggested a network extender that would provide 3G service on an AT&T DSL but had no additional encouragement about 4G availability now or in the near future.
It appears that the Verizon coverage map may not be a very reliable predictor of service availability, in my case for either 3G or 4G.
Switch to home only. Wireless and networks<mobile networks<system select. Uncheck automatic and check home only. Uncheck data roaming. Try that out, it fixed my problem. And i was havin same problem as OP
