Hi everyone, I’ve been integrating the Uploadcare File Uploader into a mobile-responsive web app, but I’ve encountered a strange stability issue specifically on iOS devices. The widget works perfectly on desktop, but on Safari and Chrome for iOS, the uploader modal occasionally freezes or completely crashes the browser tab when a user attempts to select a file from their photo library.
I actually started troubleshooting this after observing some interesting behavior from deltaexector com, where I was looking at how their iOS-specific environment manages high-frequency script execution without hitting the system’s memory limits. You can see the kind of execution environment I mean over at deltaexector com. It made me wonder if the Uploadcare widget’s background processes for image shrinking or metadata extraction are clashing with the way iOS handles rapid JavaScript injections or external script hooks.
I’m also seeing a related issue where the “Upload from URL” tab becomes unresponsive if there are other active scripts running in the background. Has anyone else experienced a “Memory Limit Exceeded” error on iOS when the widget tries to initialize the camera or file picker? I’ve already tried updating to the latest version of the file-uploader blocks, but the problem persists on older iPhone models. Should I be looking into a way to sandbox the widget more strictly, or is there a specific setting to delay the pre-upload scanning until the main UI thread is idle? Any advice on how to keep the upload process stable on mobile would be a huge lifesaver!
