Lyn, thanks for reporting this issue. The screenshots and knowing that version 118 was the first to have the issue are very helpful!

Mike, I suspect this bug is a regression from your fix for video notch bug 1849009 in Fenix 118.

The reporter's device, a Xiaomi Mi 9, has a notch: https://www.gsmarena.com/xiaomi_mi_9-9507.php

Hi,
I found more of these issues reported, all but one are with Xiaomis with Android 11 (one has Android 10):
https://bugzilla.mozilla.org/show_bug.cgi?id=1882672
https://bugzilla.mozilla.org/show_bug.cgi?id=1870658
https://bugzilla.mozilla.org/show_bug.cgi?id=1902917
And I started closing the newer ones as duplicate of 1870658 as the oldest one opened I found. Please see if this one should be closed in favor of that or should this one be kept.
I did reproduce this issue also with a Xiaomi Mi11 Lite (Android 11).
Tested build: Nightly 129.0a1 from 2024-06-27.

Do not close this one pls
This is most informative issue and the only that attracted the attention

Comment 10

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Fenix::Media' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

:tthibaud could this be triaged for severity?
Will this be looked at in an upcoming release, wondering what we should track for release.

Comment 12

[Titouan Thibaud [:titouan]]

Is the bug reproducible on non-Xiaomi devices? 
(Lorand Janos, maybe?)

Comment 13

[Lorand Janos]

I tested the following devices:

• LG Nexus 5 (Android 6.0.1) - On first launch, the nav bar and status bar remained, but from the second time it wasn't reproducible anymore.
• Huawei P20 (Android 10) - The issue was not reproducible.
• Xiaomi Redmi 9C NFC (Android 10) - The issue was reproducible every time.
• Xiaomi Mi11 Lite (Android 11) - The issue was reproducible every time.
• Vivo Y22S (Android 12) - On first launch, there was a white bar displayed, but from the second time it wasn't reproducible anymore.
• Samsung Galaxy S23 Ultra (Android 14) - The issue was not reproducible.
• Samsung Galaxy Z Fold 4 - Folded and Unfolded (Android 14) - The issue was not reproducible.
• Google Pixel 7 (Android 15 Beta 3) - The issue was not reproducible.

Tested builds:

• Latest Nightly 130.0a1 from 2024-07-30.
• Beta 129.0b7-129.0b9.
• Nightly 128.0a1.

Why "fix optional"?

Comment 15

[Titouan Thibaud [:titouan]]

Hey :Lorand Janos,
I finally got access to a Xiaomi Redmi 9C NFC, Android 10. I cannot reproduce the issue on Fenix Nightly, neither on Fenix Release.

Can you still reproduce the issue on the Xiaomi Redmi 9C? 
Thanks a lot for your help on that!

Comment 16

[Lyn]

Mi 9.

Not Mi 9T or Redmi 9.

Comment 17

[Lorand Janos]

Hey :Titouan Thibaud,
Sorry about the late reply here, I can no longer reproduce this on the same device (Xiaomi Redmi 9C NFC with Android 10), on the latest Nightly (133.0a1 from 2024-10-04).

I also retested the other device on which I reliably, constantly reproduced this issue on earlier builds: Xiaomi Mi11 Lite (Android 11), also on the latest Nightly build, also couldn't reproduce the issue anymore.

Hey John, we cannot reproduce this, but speculate it could either be a Fenix-specific issue with the toolbar or a media issue? Can you take a look?

Same problem here, also on mi9, the temporary "fix" that i found is go to device configs, notch configs and set to hide the notch, but its not as good as a real fix cause im very used to the notch settings on my phone

Comment 21

Recently Google Play decided to change my auto update settings on its own and suddenly I found that Firefox had updated. Now I have that white bar on the side again (I was using an older version of the browser before). HOW LONG? When will this be fixed?

Comment 24

[Lyn]
