App doesn't load correctly on Samsung phone with Android 7.0

How-to Discussions

Hi,

Our app isn’t loading correctly on Samsung phones with Android 7.0. The app opens, but it seems like the first view doesn’t come trough. When I tab on the icon, the phone opens an app-window but the view isn’t loading (seems transparent). I can’t interact with the homescreen because the phone thinks the app is open (which is). When I view the apps that are open the Hubper app is visible.
I’ve made a video of the problem.

The app works perfect on iOS and other Android devices. Could this be a problem with the Samsung theme? The example project works fine on the Samsung phone, so the bug should be in my project, but I don’t know what to search for.

Does anyone have an idea? Thanks!

Hi, would it be possible for you to share the code that reproduces the issue? If it’s sensitive, you can put it here.

Hi Uldis,
thanks for your reply. I upload the code to your dropbox.

Hi Uldis,

Did you found out whats wrong? We unpublished the Android app from the Play Store. Our client was getting to many reports on this bug from there users.

I’ve tried to get rid of the fuse-device plugin, but unfortunately that didn’t fix the Samsung bug.

I am investigating this issue right now. Will report back to you as soon as I know anything :slight_smile:

For some reason setting IsVisible="False" on <Android.StatusBarConfig /> and "ShowStatusbar": false, in the .unoproj makes the app not draw on Samsung devices. Removing it will make the app work. You can do that as a temporary fix.

I have never seen this issue before, need to investigate further

Hi Vegard, your fix works!

While I think hiding the status bar is nicer in this app it isn’t a showstopper. Thanks!

8

This also happens on my non-Samsung test device running stock 7.0. You should look in to this as a lot of people would like to make full-screen apps.

9

Same problem here, is there a estimate when this would be fixed?

10

We’re having the same issue, and we like to hide the statusbar for our app.
Is there an update available on this issue?

11

No, the issue is not resolved as of now.
