@darshankawar (Member):
- I will try to verify this on a tablet emulator. Meanwhile, can you try using the plugin example on the same device to check if the issue persists?
- Since it is specific to tablets, check if there’s any setting causing the file size to be zero.
- Can you test with a native Android app to see if the same behavior occurs?
@m-hamza-tanbits (Author):
- Please verify.
- I have already used the plugin example. It works on both Android and iOS mobiles and on iOS tablets.
- The issue arises only on Android tablets.
