I will narrate my experience with my phone Nexus4
I have been using since 2 years.
I am satisfied to a great extent with the performances of the phone.
As it is from Google, the quality Is very good.
It is manufactured by LG for Google, which is another plus point.
The price is also reasonable at that time.
The cons are
Phone sound is low and comes from behind that is speaker is on the back side.
Battery Life is low for a phone like this with so many functions.
Picture quality of photos is so so.
Very delicate handset
Performance and durability are good.
On the whole satisfied
