AP price for Galaxy R is RM 1400
Samsung Galaxy S II G Version - RM 1660 AP
LG Optimus 2X - RM 1230 for AP and RM 1360 for ORI
ok.. back to comparison
Samsung Galaxy R vs LG Optimus 2XIPS LCD in LG Optimus 2X seems look good but not as good as SC LCD in SGR [but it still depend on you]
RAM in SGR is higher [1GB] compared to 0.512GB in LG O2X
LG O2X has nicer camera and its camera spec also better
other than that is almost same..
Better go for SGR
Samsung Galaxy R vs Samsung Galaxy S II G Version
Basically this is the difference ->
SGS II G , has higher ROM [4GB] than SGR [2GB]
regarding the screen.. it depend on you, whether you like the Super Clear LCD in Samsung Galaxy R or Super AMOLED Plus in SGS II G ,
SGS II G has higher internal memory - 16GB . SGR - 8GB only
SGS II G has better camera spec and features such as FULL HD video recording , better secondary camera , etc.
Tegra 2 in SGR should be better when playing Tegra 2 optimized game such as Angry Birds THD , but still as par with Ti OMAP 4430 in SGS II G
Both of the phone using dual core processor, just that SGS II G has slightly higher processor [but that doenst much matter]
SGS II G has 3 color which is Pink, White and Black while SGR only have Black
Conclusion, both of them has neck to neck performance, but comparing the spec.. SGS II G is better
