smartphone performance

Hi,

i've built an application and i face weird behaviours on smartphones

my app is plugged to a sql server database.

i  have a view that brings me back about 2500 rows (so with delegation, il seems not to be a problem)

First of all

i've a filter and a clearcollect that gives me 2 values : 

ClearCollect(
    TwoDistinctValue;
    Distinct(
        Filter(
            '[dbo].[QSE_DistinctLigneArr]';
            Value(cb_LgArret.Selected.ligne) = Value(ligne)
        );
        Text(SensA)
    )
    ;
    Distinct(
        Filter(
            '[dbo].[QSE_DistinctLigneArr]';
            Value(cb_LgArret.Selected.ligne) = Value(ligne)
        );
        Text(SensB)
    )
)

i grab this collection and display it in another comboBox.

On my computer it works fine, but on my smartphones, it doesn't !

the TwoDistinctValue is empty on my smartphones, i don't understand why.

at last

i've another issue with camera

i've set up an udpdatecontext on a "on select" icon that switch between front and rear camera.

UpdateContext({DeviceObturateur: If(DeviceObturateur = 0;1;0)})

on my iphone it works fine

on my samsung it fails and stay on the front one..... (a teammate face the same)

any idea or workaround ?

I can help with your camera issue.  I use Samsung and Iphones.

The Camera control has a Camera property which is a number from 0 to 2 (I've found in my App).

I set this value to a variable, and then have a 'Switch Camera' button which increments this variable.

Also, I store this variable value using SaveData and restore it so saves the camera the user is on.

Hi @HarjitSamra ,

thanks for your solution regarding the camera it works fine.

here is my code, which manages and iOS and Android : 

UpdateContext({DeviceObturateur: Switch(DeviceObturateur;0;1;1;2;2;0;0)})

it remains my issue with my collections.
