Title:
Cellular connection drops out
Still no progress with this annoying bug? It's really one of the worst
bugs. Signal drops draining the battery, makes phones overheats.
Sometimes I only find a notification of a missed call, but the phone
never rang. The caller says the call has gone straight to voicemail.

I'm having this issue on Meizu Pro 5 with OTA-13 (stable). People

With the new MX4 firmware I am not noticing the connection dropping
during normal use. The comments in #22 are still the case though,
connecting USB can trigger a drop which is a behavior I had not noticed

@jibel, no, that is not happening, you are registered all the time. Some
of the lines you see there are not events, but answers to AT+CREG
commands.

@jibel, that behaviour might be considered a bug, I have opened bug
#1608885 for system-settings to address that.
If you see the bug again you can try to execute /usr/share/ofono/scripts
/scan-for-operators and you will see a list like:

@Pat, thanks for the logs. I can see there are time periods where you

@Pat, @jibel, could you please paste the result of executing
/usr/share/ofono/scripts/list-modems while this is happening?
Taking a look at syslog from comment #3, I see that initial registration
after boot takes around one minute, which is a bit long, but not unusual
for arale. Four minutes after
I confirm this behaviour on arale. It started 2 weeks ago or so but
thought it was my operator (Free Mobile France). Sometimes the phone
displays "Searching" and never connects to the cellular network while
another phone next to it, with the same operator, is connected.
