ya decia yo que habian tocado el spen y que los colores de pantalla eran mas suaves y mas nitido sin pixelacion, ahora lo entiendo, algunos cambio en lc1 :
Differences
1. keyboard error fixed(for korean... typing 가1이 is repeat 가, so result 가1가이)
2. S memo is better than LB1. so faster and sensitive.
3. antutu benchmark is lower score(6300->6000)
4. so smooth, almost no lag.
5. ##Fixed contrast problem. there is no rendering issue(
