Flame unresponsive on FxOS 2.6

B2G OS Foxfooding
#1

I used to run v18D_nightly_v4 on my flame and it was very stable. But then I run into problems and had to upgrade first to 2.5 builds from October and then to nightly-latest builds. I got new features such as a new homescreen and pin the web, but the phone is much less responsive now. For example when I am in an app and press the home button, I see the icons flash and only then I can use the homescreen.

I wonder if anyone else has noticed a slowdown. Or indeed if anyone has a fix. (I have tried various combinations in Developer Settings, but I couldn’t get a responsive UI.) Perhaps foxfooding on Z3C isn’t good for noticing performance regressions as it is a high end phone. But the user experience on low end phones will be even worse than Flame. Although with the recent announcements I am not sure if the low end is a priority any more.

#2

The new homescreen is still work in progress and it has quite some bugs and missing features.
The low end phones are no longer a priority for Mozilla!

For the icon flash follow this bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1224268

#3

Thanks for the reply and for the link to the bug.

I’ve gone back to the old homescreen and it still has the problem. And the homescreen was just an example. I constantly find myself tapping something, then thinking it didn’t recognise my tap, then tapping again, only for the phone to react to both taps after a delay. At the moment I find FxOS 2.6 (and 2.5) barely usable on Flame.

#4

All these issues are to be expected in the nightly-latest update channel as it’s not checked by QA!

It is important to provide the Build ID you are using or seeing these issues on - there was a bug a while back where there were issues with the tap being recognized. Also, please check the following:

I just updated my Flame to the latest nightly and I am not seeing those specific issues.

My Flame is running the following build:

Very good tip with the memory!

I have set the max for mine: 1024 MB

Here is the how to: https://developer.mozilla.org/en-US/Firefox_OS/Phone_guide/Flame/Updating_your_Flame

You only need to do this:
adb reboot bootloader
fastboot oem mem 1024

#8

My Build ID 1s 20151225030210 and Platform Version is 46.0a1. (But I’ve seen the unresponsiveness in other builds as well, such as 44.0a1 from 5 November and from 26 October.) Not sure about Gaia/Gecko version. Couldn’t find it in Device Information. The memory was set to auto. Now I’ve changed that to 1024. Didn’t see any difference.

#9

This tool has a check version script that you can run that pulls all the device information off the phone - might come in handy in the future.

Thanks, that’s handy! Here are the full details.

The n/a thing is bit strange.

#11

Yes, it is a bit strange.

The full information should look like :

Gaia Revision
Gaia Date

Please provide the firmware release/incremental/date. Flashing just the
gaia could lead to unexpected results.

What I did is flash v18D_nightly_v4 and then fota update through nightly-latest channel.

#13

Odd. I’m not sure that the gonk layer changed that much though there are a
few fixes that we do need to push since the v4 base build. We’re trying to
push for a new base build currently. It should be coming within the next
couple of weeks. Hopefully that may solve the issue.

I would highly recommend switching to the new home screen, not the old. I
know that is contrary to what Mihai mentioned earlier. Certain addons
might not work if you have any addons installed.

Do you per chance have an uptime on your phone? Doing an adb shell
b2g-info will also provide some memory information. adb shell dumpsys also
provides some dump state information about the device.

Does a reboot help?

Reboot doesn’t help. I’ll wait to see if the new base image will help. Thanks!

#15

FYI, the new base should be out now:
https://developer.mozilla.org/en-US/Firefox_OS/Phone_guide/Flame/Updating_your_Flame

#16

Thanks, I have updated to the new base and to the latest nightly from it. It actually fixed some issues, such as homescreen icons being redrawn. But the responsiveness is still lacking compared to 2.2/early days of 2.5. I guess I am just more used to it now.
