I am using a customized android application in my Galaxy S4. The application is using a web browser from within and the entire app runs on that. However it is transparent to the users that it is a web browser. The application has certain number fields which accepts only numbers. When keying in the numbers it does not display the numbers in the application. If I switch to google keyboard, the numbers can be entered and are displayed too. This issue is with other S4 and S3 phones too.
If the website is opened directly via the phone's browser, there are no issues.
