OTA-6 Call for Testing

UniSuperBox · 28 Nov 2018, 21:15

Today, my phone crashed at least 5 times. It happened sometime before the update, but not so often. I was listening music with the music app and doing another thing at the same time

When this happens, does the phone go back to the "BQ" boot screen or return to the "Ubuntu Touch" loading screen? Also, can you send the contents of /var/log/syslog to a service like paste.ubuntu.com so I can take a look?

the keybord fly off and I have to leave the discussion, sometime the app to get the keybord back

Do you mean the keyboard continues off the top of the screen? If so, I've never seen that behavior. If the keyboard dismisses as normal but never comes back, that is related to https://github.com/ubports/ubuntu-touch/issues/595.

It go back to the "Ubuntu Touch" loading screen a restart quicker than a complete reboot. I will give you the logs tomorrow.

Ok, it is the second issue: the keybord dismisses and never comes back.

Tell me if it is enough.

Thanks

@teigneux if you only run one app, not several at the same time, does your phone crash?

IMO 1Gb RAM devices can't handle more than 1 app open at a time, and even that with some care

Search for the word "Killing" in your log and you'll see how your phone is running out of memory constantly.

There is this warning about certificate not trusted

jezek · 29 Nov 2018, 14:31

Pardon my intrusion, @Teigneux maybe it's related to Increase swap space issue, which is discussed in other tread.

Yes

what? it worked well before. And not only with two apps. If i cannot listen music and read a sms at the same time, I will not longer use this system!

I will check.

Teigneux · 29 Nov 2018, 18:10

@jezek thanks, I will take a look. The phone is clearly slower than before, it should be a ram or a memory access issue.

kwah · 29 Nov 2018, 23:14

Hm, I would like to join testing, but I cannot switch to rc channel.

There is no channel switcher in the System Settings -> Updates -> Update Settings page. Is there other way to change the channel?

It used to be there, I used flip to rc -> back to release to get OTA-5 update.

advocatux · 30 Nov 2018, 01:26

@kwah something is wrong in your phone then. You should be able to tap on "channels" in the "Update settings" page to select any channel you want.

You can try to run this command in your device terminal sudo system-image-cli --switch 16.04/rc

Alarm clock is not trustable anymore, changed already in ubuntu 24. In ubuntu 26 w48 again it didn't ring and indicated just after turning on the screen. Phone was on charge, i checked the alarm time and turned actively off the screen in the evening. (clock app was opened when i turned the screen off)
Something changed in the last updates, please check this.

UniSuperBox · 30 Nov 2018, 14:15

@teigneux

Yes, that log has exactly what I expected at line 125:

Nov 28 17:02:32 ubuntu-phablet kernel: [10756.588033]Killing 'unity8' (2558), adj 10,
Nov 28 17:02:32 ubuntu-phablet kernel: [10756.588038]   to free 113312kB on behalf of 'Thread (pooled)' (15633) because
Nov 28 17:02:32 ubuntu-phablet kernel: [10756.588043]   cache 16288kB is below limit 16384kB for oom_score_adj 6
Nov 28 17:02:32 ubuntu-phablet kernel: [10756.588048]   Free memory is -2764kB above reserved [gfp(0x200da)]

This is definitely a memory problem which manifests heavily on devices with 1GB of RAM.

UniSuperBox · 1 Dec 2018, 08:49

@htc_tattoo, we'll need more info than that to reproduce the problem. Which device are you using? How and when are the alarms set? Do they repeat? What is the position of each setting on the edit page?

Mic_ · 30 Nov 2018, 17:25

@advocatux I am using a BQ E5 and a Nexus 5 - both with UT 16.04 RC.

As you descibed above on the BQ E5 (with 1 GB RAM) I always have problems using 2 different surfing apps (e.g. QWANT and browser). One app is always freezing and starts again if I use the other one.

This problem was also existing with 15.04. If I use e.g. SMS, phone, mail and QWANT, I do not have the problem - only with 2 'surfing apps'. On the Nexus 5 I don't have this problem at all.

This is actually the most annoying problem on my BQ E5.

advocatux · 30 Nov 2018, 17:29

@mic_ yes, it seems that any app related to web browsing is more memory hungry than the other ones.

I have the same problem with my BQ E 4.5 (also 1GB RAM)

Mic_ · 30 Nov 2018, 17:36

Sometimes my BQ E5 crashs and returns to the "Ubuntu Touch" loading screen. This never happened until now on the Nexus 5. And it seems it happens less often with OTA-6. But at least 2 times until now.

If my BQ E5 crashes because running out of memory isn't there a way to write data on the phone? You probably already tried....

I now turned back to my BQ E5 as daily used phone - because the energy management of this phone is now really phenomenal !! (I always have enough power for more than 1 day). This makes it more handy than the Nexus 5. ;/

advocatux · 30 Nov 2018, 17:50

@mic_ yes, that's unity8 crashing after running out of memory, and no, swapping wouldn't be a solution for that.

I have the same dilemma than you: battery life or stability. BQ E 4.5 against Nexus 5 :P, but I've chosen the latter as my daily driver

kwah · 30 Nov 2018, 19:51

@advocatux I do not have "channels" in the "Update settings" page. Command you suggested resulted in error: Exception occurred during update; see log file for details

Any idea, which log does it refer to?

advocatux · 30 Nov 2018, 20:03

@kwah have you tried to clean system-settings cache, data, and config files using UT Tweak tool? Then reboot your device, and see if you can switch channels.

I don't know which log it refers exactly but maybe is ~/.cache/upstart/application-legacy-ubuntu-system-settings-.log

Mic_ · 1 Dec 2018, 00:29

And I just realized that there is a difference between BQ E5 and Nexus 5 in getting notifications.

While Nexus 5 immediately shows incoming new mails on the phone with a green light, BQ E5 is not doing that or a longer time later. It seems so that BQ E5 in standby mode is loosing or having less internet connections.
