Question about Innioasis G1

Yes, the browser seems to be uninstallable or at least deactivatable. The instructions describe that you can deactivate the browser under Settings > Apps > Browser; for Chrome, it is also mentioned that the app can be deleted and parental controls can be activated. I am not entirely sure if this works the same way for every firmware version. Depending on the version, the option might be named differently or only be available to a limited extent.
