Guoyuan Securities Mobile Edition cannot be used on Samsung mobile phones.

According to your description, I suggest you try the following methods:

1. It is recommended that you uninstall and reinstall the software.

2. Try to change to another version.

3. If other third-party software can be used normally, only this software can't have compatibility problems with the mobile phone system.

4. Update the mobile phone system version and then try to install it.

5. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ), restore the factory settings (enter the phone settings-reset-restore the factory settings) or send the phone to the nearest Samsung service center for testing and further processing.

Please visit the address and contact information of the service center:
