Android App incompatible with many QHD phones

Question

My app shows as incompatible with some devices that have QHD resolution (such as Nexus 6 and LG G3). I have not put <compatible-screens>, since Google says that it is better not to use this, if someone wants to support all screens.

The thing is that I am not able to find the exact reason of this filtering, as Google does not provide an explanation. I am left with the message
