Republic Wireless App Version
22.214.171.124 - October 23, 2020
I confirmed I am having the exact same issue on 2 different model pixel phones (3 phones total), except it happens both failing from WiFi to cell and from cell to WiFi.
I have noticed this occurring for months (multiple different Android Security Fixes) but always figured I was bumping the mute button or something.
It’s a little embarrassing when I am on a conference call with 20+ people and I think I am muted to have someone mention the background noise.
To answer @jben, I would say that the cause of the calls failing from WiFi to cell is kind of a moot point - that is precisely what the app is designed to do when the network becomes unstable. However, in my case it usually occurs when I am on long conference calls and have to leave the house.
I was easily able to reproduce this issue by calling my second phone, muting the call and then disabling WiFi. Within a couple of seconds the phone is un-mutes itself.
I then muted it again, turned on WiFi and after about 2 minutes it went back to WiFi and again it un-muted. The more troubling thing was even though it said it was not muted, the Microphones stopped working all together. No matter how many times I tried to mute/un-mute I could not regain outbound voice until a new call was started (I got an inbound call while testing, answered and my Microphone was working for the new call).
Did this with both phones multiple times, same result every time.
Out of curiosity, I started a new call on Cellular, muted and then enabled WiFi. When it failed from cell to WiFi the phone again showed that it was un-muted, however the microphone did not work.
I did force stop the Republic Wireless app and clear its cache/data which did not help.
Actually knowing what is causing my phone to un-mute makes me a bit more comfortable with the situation since I have been obsessively watching my Mute status while driving and now I know when its most likely to happen.
I see the original post is over a month old so I will dig around to see if anyone else posted a fix…
