REPRODUCIBILITY: unpredictable
OS VERSION:Tampella 5.0.5.71
HARDWARE: Jolla C2
UI LANGUAGE: English
REGRESSION:
DESCRIPTION:
This happened a few hours after updating to Tampella 5.0.5.71. But it has been happening often since the C2 was returned to me in March (with build 5.0.0.55 installed).
Symptoms: the phone is well charged, and has connected to local wi-fi, either at home (today and previously) or at work (on earlier occasions). It shows WLAN with the local connection and all bars. But MeeCast shows ‘no data’ and doesn’t refresh.
I toggle WLAN off and back on.
MeeCast updates.
But the connection is lost again.
Within a few hours, the phone runs hot and the battery drops quickly, down to nothing if this happens overnight.
Each time this happens, I charge the phone to full. shut it down completely (power button then Off icon), wait, start it up, start the usual sailfishOS apps, wait several minutes, start AppSupport, wait, then start MeeCast and WhatSapp. Sometimes I’m lucky and it runs fine, connecting at home and at work, no issues for a week or more; sometimes the problem occurs within a day.
If I forget to check whether the phone is actually connected, then WhatsApp messages aren’t sent, and an SMS reports ‘problem sending’. At that point I might see that WLAN shows my home connection, but the phone and I are somewhere else.
If I’ve tried to send an SMS when WLAN appears to be on but isn’t, I can’t send any more texts even if I reconnect, or turn off WLAN to use cellular.But

After installing Tampella 5.0.5.71, I checked the new AppSupport settings but didn't change them.

I don't think this relates to my router settings, since it's also happened when the phone has been connected to the work network, in the office.
I've wondered if there's a race condition at startup, since sometimes all is well for days and other times not. If logs would help, please give me instructions.
I do appreciate all the work that goes into SailfishOS. The release notes for 5.0.5.71 noted fixes for C2 connectivity and I really hoped it would make my phone reliable--so sad that we're not there yet.
