Hi @Rodrigo1,

Could you please share a bit more about your issue?

Do you mean that the Camera control captures a blank picture when you navigate back to the screen from another screen?

Based on the issue that you mentioned, I have made a test on my side, and don't have the issue that you mentioned.

The screenshot as below:11.JPG



Set the OnSelect property of the Camera control to following:

UpdateContext({Counter: Counter+1}); 
Collect(CameraPics, {Name:"Report" & Counter & ".jpg",ContentBytes:Camera1.Photo, '@odata.type':""})

Set the Items property of the Gallery to following:


Set the Image control within the Gallery to following:



Please check if you have typed the following formula within the OnVisible property of the screen which contains the Camera control:

Select(Camera1)   /* <-- Camera1 represents the Camera control (Camera2_3) in your app */

if yes, please remove above formula from the OnVisible property of the screen which contains the Camera control.


If the issue still exists, please consider take a try to re-create a new app on your side, then take a try with above solution, check if the issue is solved.

I will try to explain more about that.


I am create one APP to report about some problem. These screen, there are two option that i would need to complete:


First step (Picture name 1):

I would need to complete some question and all questions are visible just when i select "Dados" in top side, because all questions are with formula Visible: !_showDetails 



Second step (Picture name 2):

After completed the first step, I would need to take a picture and select the best picture in my gallery. For that, i need to change in top side to "Foto", that the options are with formula Visible: _showDetails


The problem:

When i change my screen in left side (picture 3) for some where and return to check my screen "Quality Report" (picture 4), in my gallery pops up the "Blank picture" (picture 5).


The picture 4 and 5 i will send in other mensage.


Do you know why this happen?


If you have some questions about that, let me know!
