Need to download that app but get frustrated that it's incompatible with your phone? Today, it'll be possible.

Your Android Device must be have root access, you'll need to download ES File Explorer from the Play Store.

After downloading the required app, open it, head to settings by pressing the Menu Button, scroll all the way down and tap Root settings, mark Root Explorer and grant it Super User permissions after being asked to do so, also check Up to Root and Mount File System.

Now exit the app's settings and head to /system/build.prop and open it with a text editing tool.

Open build.prop and you locate 

ro.product.model = %YourDevice%

ro.product.manufacturer = %YourDevice%

Change these values to Nexus S and samsung. They should look like this:

ro.product.model = Nexus S

ro.product.manufacturer = samsung

Press the Menu button, and save the file.

After that, go to "Manage Applications" under your device's settings, locate Google Play Store and clear data and cache, then restart your device.
