I played with my bro Note 8 which he bought last week. I noticed :

1. Cannot enter into menu when lock screen seems failed to detect my fingers. Once inside menu, the touch wiz seems working fine.
2. Internet browsing very very slow. But using wifi for browsing is fine.

Any users facing the same problem?

Will try remove the magnet casing. Now in testing period. Hope will resolve the issue.

1 thing i notice regarding all Samsung tab (Note 10.1', Note 8', Tab 3 8inch) when using data for browsing extremely SLOW compared using wifi. Using Hotlink full bar with H+ still like a snail. Even can't load Play Store. Wonder what is wrong here. Tried morning & night time with different hours still the same. Haih...
