So I dropped WA a while ago and switched to Signal Messenger. On the assumption that Signal is secure (but they sure have a lot of updates), I wonder if the Android OS itself can leak info about what one is messaging? For example, if you have a SWYPE keyboard, is it phoning home, telling Microsoft the words that you type in Signal? [MODERATOR edit to remove inflammatory political reference.]
And what is Android itself sending to Google? Half of my phones are rooted with either a custom ROM (no Google Play stuff) and AFWall+, or stock OS and AFWall+. On the rooted phones with stock OS but AFWall+, I see (and stop) stuff trying to talk to Google.
But the phone that I use for Signal cannot be rooted, so I can only use a rudimentary (VPN-based) non-root firewall on it. (Which, as a minimum, cannot stop Google Play.)
Am I being stupid? Am I (and most others) open to side channel leaks when using Signal on non-rooted, non-locked down phones?
