A friend of mine has a Nexus4(it's nice too have the device from which I'm using all the code for cm10.2 :D )
He told me that things look very small on my screen compared to N4.

And he is right. Nexus4 and Mi2 both have the same screen resolution but different screen sizes.
BUT both are set to 320dpi which can't be correct.

So I calculated the real ppi using this tool:

N4: 312.47 PPI
Mi2: 341.54 PPI

As you can see both don't have 320ppi but Mi2 is MORE than wrong. I took screenshots from both 320ppi and 340ppi settings on our device and well 340 looks much more like nexus4 in my opinion. But decide yourself:
left: 340 - right: 320

So what do you guys think? Which ppi configuration do you like more?

340 causes problems with some apps like Apollo so I think that xiaomi made the right decision with 320.

The advantage of PA is that u can set a different dpi value for every app.
This is also possible in CM10.2 with xposed
