Hi Jonnathan,
Greetings from Syncfusion support.
We understand that you are facing an issue while using File
Manager on your mobile device. To validate the issue, we have checked our File
Manager component on different mobile devices but were not able to replicate
the issue at our end. Please check the below screenshots for reference.
Sample: https://stackblitz.com/edit/angular-jfudd5?file=app%2Fapp.module.ts,index.html
The reported issue is caused by a missing style sheet
reference. So we suggest you check once whether the style references for the
File Manager component are properly mapped at your end. You can refer to the
below links to map the style sheets.

Instead of using a local resource on your server, you can
use a cloud CDN to reference the theme style sheets. Refer to the below link.

environment. If the issue occurs in the shared sample as well, please share

issue. If possible, replicate the issue in the above shared sample to provide a
prompt solution.
