too big product page width

[Etay56]

as you can see in the picture below its possible in mobile to zoom out and make the product page fit half of the screen, I would like to get it fix

Important to mention, it happens only when someone zoom out on purpose, not immediately when the product page is opened
but I would like to disable this, thanks in advance

Hi @Etay56 ,

May I suggest to update code these steps:

1. Go to Store Online-> theme -> edit code

2. Layout/theme.liquid

3. Update code 

From 

<meta name="viewport" content="width=device-width,initial-scale=1">

To 

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1.0, user-scalable=no">
