Here is a quick list:
1- Wifi poor reception (worse than sgs, desire,desire hd and Iphone 4)
2- Screen is blueish like my first sgs(In miu rom or cm7 it isn't blue because I can set the red color with voodoo color!!! so it's a faulty software calibration damn!!)
3- Gps lock is fast but not strong, it keeps disconnecting with Google navigator and works better with Sygic. Worse than Desire, Desire hd, Iphone 4, but better than my Sgs.
5- Poor sound output through headphone!! Worse than all the other devices except Sgs, but since Supercurio realeased Voodoo sound it rocks!
I don't know if this problems could be solved by the community, but I am very frustrated. I put my trust in Samsung again and in the online reviews but now i fell betrayed.
I hope that I could return my phone to get another device but since htc locked its bootloaders I don't know what to choose...
I hope You all find my post useful if You are going to buy Sgs 2.
Could anyone that has Lg phone like optimus 2 tell me if this phone is good or if it has a lot of problems like galaxy 2?
