@truscellino Yes, it's still happening for me. Tapping the network name again doesn't help the situation. Surprisingly, turning WiFi off and on again doesn't help either (I would have expected this to work). The only solution is to turn airplane mode on and off again or to reboot the phone.
I recently changed the channel my router uses and it had no effect on this issue. Good luck with your investigations. I have only one router and no convenient way to test others.
@lakotaubp If I update to 2FA (and still have the E4.5) I'll update this thread, thanks again 
@lakotaubp Thank you. I've carried out these steps but I think we are talking about two different things. I can't add a Google Account in the system settings 'Accounts' section.
Maybe when I enable 2FA (soon) the Accounts will work for Google. The UbuntuOne account added fine.
Dekko 2 is okay
@lakotaubp yes, I'm using that latest beta of Dekko 2. No 2FA and explicitly allow "less secure apps" access. Still not working though.
@lakotaubp thank you, I've updated the title to show that I am running 16.04 stable.

Here is /var/log/syslog https://www.dropbox.com/s/ug0632bcv34hepr/syslog.crash?dl=0
I will leave this file shared for as long as possible.
As soon as a call comes in, or I make a call, the screen goes black once the dialer has appeared. If I rotate the phone around the screen flickers briefly on/off very quickly (like a strobe). It doesn't stay on long enough to let me use the mailer. So I can't access speaker phone or use automated systems.
TODO:
Reproduce and provide logs.
The dialer will be .cache/upstart/application-legacy-something
/var/log/syslog
@advocatux That does help. I'm not using 2FA but I should.
@negations No luck, unfortunately. Maybe something else is causing the issue. But I did try a reboot and I have lowered the security of my Google account. I'll raise it again before the end of the day. Thanks for sticking with me
@negations thanks for the link! I enabled access for less secure apps, but UT still can't associate the account for some reason.
@negations thanks. Google seems to recognize the attempt:
I can't find the option you mentioned 
@advocatux reboot worked, thank you. One less thing
When I pull down the menu for rotation, there is nothing there. Just black. So my rotation isn't locked and I'm triggering rotation in my hand when I don't actually want it. Edit: I see rotation lock is available and working in the settings. Can it be removed from the pull down menu since it doesn't work?
Adding a Google account gives a perpetual spinner after I sign in and click 'Allow' (blue button) and doesn't link to Google.
Are there workarounds for these issues?
Thank you. I'm trying to reinstall (with 'wipe' to be sure). My E4.5 has a black screen with “=> FASTBOOT mode…” displayed at the bottom. Should I expect some kind of feedback about the installation process or is there something wrong? It's been like this a long time now. I'm on MacOS.
Edit: Switched to Ubuntu and installed the snap installer. It falsely reports that an update is available, but besides that it is now installing to the device. Fingers crossed.
Edit 2: Installation completed. Thank you!
@thebird thanks, that's a positive!
My E4.5 had been in storage for some months while I was finishing college. I've updated it now and see two old problems still there.
1 is that WiFi stops working and I have to use airplane mode (on / off) to fix it a few times every day.
The other is that when I phone someone, the keypad is unresponsive (sometimes blank too) meaning I can't turn on speaker phone or use automated phone services.
Is this a common problem or is my phone just in a peculiar state? I'm happy to provide logs if required. Or if it's just an oddity with my device I can re-flash it.
a download needs to be relocated so the correct app can see it. Currently downloading a pdf is a good example of this. The document viewer doesn't open it if I chose that as the action for the download. Instead I must save to Downloads and later move to Documents.
sometimes I discover there is a problem with space and need to quickly delete some music.
When samba was working, I used it to access documents on the home share. It worked very nicely.
Which are the most important features for you?
Bookmarks for fast navigation
Swipe up from bottom for quick access to other volumes
Cut/Copy/Paste/Rename
Samba
Which are the common tasks you try to accomplish?
Fix file locations so the correct app can see them (usually move from Downloads to ./Videos or ./Music, for example.
Delete when space is tight.
Access samba shares to use media that wouldn't fit on the device (I have a large collection on the home server, I can copy a little at a time and delete later).
How the current version of File Manager fails to meet your expectations?
It's actually very good. I have no complaints, other than Samba no longer works.
