I've started to have constant drops while I'm on the phone and I think that is related to weak signal. I have a Samsung S6 bought in Dec.2015 so a brand new phone.
I was thinking that touching somehow the phone's display to my ear I'm causing that but yesterday trying to call 3 times my bank through my hands free it dropped 3 times the call. Moving about 100 m I've succeeded to make that call.
Any ideas? Thank you in advance.
To disable LTE mode, you need to go to Settings -> More Networks -> Mobile Networks -> Network Mode -> select WCDMA/GSM auto connect instead of LTE/WCDMA/GSM auto connect.
You can also refer to this video here for more info.

Since you mentioned that by moving about 100 m you get better reception, I'm thinking about a location problem.
There might be a blind spot at that location, I'll ask you to try and disable the LTE and test again.
You should see a nice improvement.
Keep me updated with the results.
