My almost-new V20 has suddenly started losing and changing tower signals all the time. One minute, it will have a pretty good LTE lock, but then it will randomly drop to 3G (if I'm lucky), and sometimes just drops altogether. I am missing lots of calls (goes straight to VM like I have it turned off), and many calls drop a lot... forget HD quality.
When I first got this phone, it was working great... always a strong 4G/LTE lock.
I've tried the entire troubleshooting gamut... Verizon's troubleshooting tool, many factory resets, cache wipes, SIM and SD card re-seats, battery pulls, LG software/update utility on the PC w/USB cable (the 90 minute repair process), etc. EVERYTHING... for three days effort now.
I've completely exhausted everything that I, as a tech-savvy IT guy, know how to do.
My suspicion is now settling on that I have a hardware failure or SIM card needing replaced???
I had to have a shop change my screen since it cracked several weeks ago, so I doubt the warranty is still valid (or is it)? By the way, it was working fine after the repair for a couple of weeks at least; so I highly doubt that is related to this.
Can I change my SIM card at least, to try that, first? Seems easy enough a thing to try.
