For the past couple of weeks I have had problems losing my network connection affecting phone calls, text messages and data access. The problems seem to be occurring more frequently, and have not been able to identify a consistent pattern yet.
Phone: On 2-3 occasions recently, I have had calls dropped. I see that I have no [phone] network connection. In each case I've been in a location where I frequently make calls. Twice this was while on a major freeway in the SF Bay Area. In each case I do get a signal back, but it takes several minutes until I re-acquire a signal.
Text: On multiple occasions (3-4 in the past week), I have tried to send text messages from my office (in San Jose), where I have not had problems in the past. After waiting for several minutes to re-acquire a signal, I re-booted my phone and my text messages were sent as soon as the phone re-booted. Note: changing the phone to airplane mode and then off, did not resolve the problem.
Data: On multiple occasions (8-10 times in the past couple of weeks), I noticed that my phone shows "4G", but no arrows and I have no data access (i.e. no access via web browser, can't use any email apps, can't use any apps that use data access). Once I lose the data connection, it never re-acquires the network even after moving and/or waiting in excess of an hour. The only way to re-acquire data is to re-boot my phone.
This seem to have started 2-3 weeks ago, but definitely getting worse over the past week - very, very frustrating!
Using Samsung S4, running Android 4.4.2. I don't recall installing any new apps or new O/S versions in the past couple of weeks, though many updates auto-installed.
