No gps no way to import contacts and headphone jack not working

GPS

Have you installed the application Positioning - <your region>?

Contacts

If I’m not wrong, there is a bug with contacts and photos. Open your vcf file with a text editor and remove the property PHOTO.

Headphone

There is no sound routed once you plug your headphone in? What happen once your screen is turned off and you plug in your headphone? You screen should wake up. Is it your case?
