My LG G3 d852 (Android 6.0.1) works well for calls, texts, and sending emails (even with attachments eg photos). But the d852 disconnects after 3-4 minutes if I tune to a news station or a music station. I've found no guidance on the internet, The many helps and tips don't present settings options that match the d852 (originally Rogers of CA), unlocked and working with Tracfone and CenturyLink. I generally use my phone at home. My d852 does not disconnect after sending a text. Is there a way to turn off "roaming" or GPS re-determinations for other wifi signals?
