HTC Droid DNA gps problems

Hello people,

I use a Droid DNA since it appeared and I’ve been through all the Android versions for this model. Before Sunshine becoming paid and the last FW version, I’ve used even unlocked FW from different ports.

After the lasat update 605.5, I started to get gps freezes and lost signal in Google Maps / Waze and Mapfactor. For a couple of week it worked with a phone hard reset. But nowdays I don’t even get a gps signal (checked by GPS Status application, with 0 sattelites found in clear sky).

Is there a software fix for this?
Or do any of you know where is the GPS antenna for the droid DNA … maybe I have a bad radio contact?

Thx for any help.
