I'm developing a web and mobile app called Bibliocards using Ionic, Capacitor, and Angular. The app works fine for most users, but a few have reported that it only shows a blank screen on Android devices (e.g., Samsung S22 and a Samsung tablet). The same issue occurs both in the mobile app and the web version when accessed through Chrome.
What I've tried so far:
- Restarted devices: No change.
- Cleared cache: Didn't help.
- Updated Android System WebView: Up-to-date.
Technical details:
- Framework: Ionic + Capacitor + Angular
- App Type: Web + Mobile
- Android versions affected: Android 12/13 (so far)
- Devices with issue: Samsung S22 phone & Samsung tablet (unknown model)
- Website: Affected as well
Observations:
For most users, the app works fine.
The black screen appears immediately after launch—no splash screen visible.
No content is rendered; just a persistent black screen.
Questions:
How can I better debug this issue remotely on a user’s device? I'm planning to implement Sentry.
Are there known issues with Capacitor/Ionic and Samsung WebView?
Could it be related to specific WebView settings or device configurations?
Any advice or insights would be greatly appreciated! Thanks in advance for your help.
