1. Users connecting with F5 Access from an Android device see string "function () {[native code]}" in the Logon Page Form 'Username' field. 2. This issue only affects the F5 Access embedded browser. It works fine when connecting from the same Android device using Chrome. F5 Access from iOS is also working fine.


The string "function () {[native code]}" appears in the Logon Page Form 'Username' field.


Configure an access policy with modern customization that includes a Logon Page.


This solution is temporal as changes are lost after an upgrade. steps: 1) create a copy of the original "main.js" file # cp /var/sam/www/webtop/public/include/js/modern/main.js /var/sam/www/webtop/public/include/js/modern/main.js.origin 2) edit the file using an editor (e.g., vi). # vi /var/sam/www/webtop/public/include/js/modern/main.js modify window.externalAndroidWebHost.getWebLogonUserName to window.externalAndroidWebHost.getWebLogonUserName() and window.externalAndroidWebHost.getWebLogonPassword to window.externalAndroidWebHost.getWebLogonPassword() 3) Restart BIG-IP
