Default GPS Problem, Screenshot and Video inside


I have a Nexus 5 32GB 312k since february 2014.

The problem is gps because seems that not works very well.

When i bought this phone, gps when changed direction, works without lag.

Now works very bad.

I tried to change back cover with another ( original ) without success.

I can lock always between 6 to 8 satellities, yesterday i fix more satellities but accuracy and snr is bad for me.

but please tell me if is normal or i can get rma.

4.4.4 Xposed Framework and last google maps version. ( i tried to disable xposed framework without differences )
