If your Cozi / Cozyla Collage Screensaver Go to product viewer dialog for this item.
is failing to load, displaying a black screen, or getting stuck on a single photo, it is usually caused by incompatible file formats, conflicting device modes, or software sync glitches.
Follow this organized troubleshooting guide to get your photo collage rotating properly. 1. Fix Incompatible Photo Formats (.HEIC vs .JPG)
The most common reason local collages fail to advance or crash is the use of iPhone live photos or Apple’s default image formats.
Convert Extensions: Ensure all images in your collage are strictly .JPG or .PNG.
Remove HEIC Files: The software cannot natively process Apple .HEIC files or live animations in the local folder, causing the screensaver to freeze.
Re-download from iCloud: If pulling from an iPhone, log into iCloud via a browser, choose More Download Options, and select Most Compatible to force a JPEG download. 2. Disable Conflicting Screen Modes
Certain built-in Android and security settings block the screensaver from triggering natively.
Turn Off Bedtime / Night Mode: A known system bug causes units to black out or freeze if Bedtime Mode overlaps with the screensaver window. Turn this feature off completely.
Remove Device Screen Locks: If you have set up a password, PIN, or pattern lock to wake the device, it will completely prevent the photo collage from launching. Change your security setting to “None”.
Uncheck “Photos Fill Screen”: Go to Settings > Screensaver > Photo Settings and uncheck “Photos fill screen” to prevent improperly sized images from crashing the layout canvas.
