Customising iOS Wallpaper

Customizing iOS Device Wallpaper with Dynamic Text

What

FileWave v14.10.0 introduced a new feature that allows customisation of wallpaper on iOS devices. This feature enables the additions of wallpaper text and with FileWave's parameters within Profiles, a single generic profile can be used to display Serial Number, Department and Assigned User, simplistically on all devices.

When/Why

Some suggestions of using text with wallpaper include:

How

To utilise this feature in FileWave v14.10.0:

Note this example demonstrates the use of a parameter to supply the device's Serial Number.

It's that simple! Now your iOS devices will have a customized wallpaper that displays the information configured.

If the image's aspect ratio doesn't match the device's screen resolution, iOS or iPadOS will resize the image which may lead to portions of the image being cropped.

Even where an images resolution matches the screen resolution in one orientation, when rotated between landscape and portrait, this can no longer be the case.  The consequence is a resize of the image, also leading to cropped edges.

The Text is burnt into the image and as such, if not placed with consideration, could also become cropped.  Test the outcome of the image with text in both Portrait and Landscape.

Custom iOS Wallpaper Dynamic Text Tips

What

Consideration of the size and where to place the text being added to an Apple mobile device's Wallpaper.

When/Why

When adding text, there are 3 Font size options, plus 9 possible locations for placing text.

Note, the preview is portrait, but this is not necessarily how the image will appear on the device.

The Font used is GothicA1-Regular and the sizes refer to:


SMALL MEDIUM BIG
FONT SIZE 65 80 95

Image uploaded to FileWave must be smaller than 2MB to add text, to help protect against undue heavy load on the server.

How

Consider the devices currently managed.  An image of the correct size should be required for each different device screen aspect ratio.  Unfortunately, MDM cannot retrieve screen resolution from devices, but each device type resolution can be observed at the following:

Alternatively, a tool like Mactracker lists details for all Apple device types.

Smart Groups

Since a Wallpaper Profile Command Policy will be required for each screen resolution, devices need to be targeted appropriately.

Consider the following method:

Obtain the Product Name for a device type to be managed (e.g. iPad6,11).  Cross reference this with something like Mactracker to obtain details.

It may be sensible to include the screen resolution as part of the group name, but not use the Product Name.  There is overlap with device types and resolution.  E.g. both 'iPad 6th Gen' and 'iPad mini 5th Gen' have a resolution of 2048x1536, so one group could be used to target both device types.  Example group name: iOS 2048x1536

Example of multiple device types for the Smart Group which all share the same resolution.  Note the 'one or more expressions must be true' and the 'Main Component':
