Dear friends,
I bought a lcd + touch screen + frame + small parts from China. when I installed on my phone the screen worked but the colors are abnormal and he is unreadable. I tried the screen on another S2 but the same problem appeared. I don't know if that is a hardware or software problem?

First the Samsung Galaxy 2 series has MANY sub models make sure that the parts you ordered are for your SPECIFIC model, I know this is stupid however there are SOOOO many models of that phone.
Second off may want to try a hard reset on the phone if possible.
Third make sure the screws are all in snugly, for most modern smart phones the screws also do a fair bit of grounding and if one isn't seated properly it make cause weird issues.
Lastly take an eraser and press it firmly but gently onto the screen and see if you can get the colors to change, if they do not shift into a rainbow or jet away from the eraser I would say the LCD you received is faulty.

You can try clean the connectors with a toothbrush and alcohol, just a little grease there can cause these issues.
