Chrome is typically what we recommend. It sounds to me like your javascript is not functioning properly, so be sure to check your settings and make sure it's enabled (JAVA is not the same thing as javascript, so be sure you've got the correct setting turned on).

Firefox is another browser option. You could try that and that would help narrow down the cause.

I don't, I don't use tablets at all. You should be able to download the mobile version from Google Play or the Samsung store.
