1. Eyes on Samsung but reccomend me any brand that got good screen compared S.Amoled +
2. Budget Rm1500 -RM 1800
3. Dual screen and not more than 4.5" screen size.
4. Good screen + good battery life.

currently used galaxy s plus,but bored already and want to taste dual core Android phones....currently interested in galaxy s2 but are there others phones than is more power than s2 or should i wait for galaxy s2 plus?

razr maxx will be 2k or higher when release, the only option i will consider is galaxy s2 , galaxy nexus and droid razr .
