Hi,
I install the last update last tuesday. I observe when I'm calling the phone take a time for initiate the communication. During this time the phone switch from 4G to 2G. Why the phone switch ?

really short answer: (you can find a more detailed one with google)
because 4G doesn't support "classic" telephone connections, only VOIP services are supported

4G doesn't support voice i think. Its normal.

I check on Internet effectively 4G-LTE doesn't support Voice, the 4G-LTE Advanced support both (voice and Data). Do you confirm that : Jolla support only 4G LTE ?

This post is a wiki. Anyone with karma >75 is welcome to improve it.
The problem is really irritating during calls when the sound quality and volume drops dramatically as this switch from 4G;3G to 2G occurs. It happens in more than 90% of my calls and can appear in the first few minutes, it also never goes back to 3G after that. This should be addressed, if possible. It's a phone after all.

This decision is up to the network operator not the handset. The handset follow strict orders from the basestation. It is common for an operator to push calls in the GSM band to save 3G frequencies for mobile data for the use of other people in the cell. For example I made a call with my Nokia E51, I was in the 3G network and after the call I was using 2G. If you don't want to get pushed in the 2G band you need to set your Jolla to 3G only https://openrepos.net/content/coderusofono/patch-more-network-modes
max ( 2015-09-10 19:03:26 +0200 )editThanks. Looks like it's for 1.1.7.x only, I'll give it a shot shall it be updated. Won't 4G + 3G do the trick?
