    I got the Xperia Z1s 2 weeks ago and I love the phone. Great Battery life and really fast. Also, another year of PS Plus is not too shabby either.

    The only problem i'm having is WiFi calling working consistently. I have my phone on Stamina mode with Wifi calling on because i dont get great signal in my house.

    Here are the problems i'm having:
    My phone sometimes does not ring, then i get a voicemail.
    My phone will ring and i will answer but hear nothing.
    The other night the person on the other end was complaining that the audio was going in and out.

    I just turned off Wifi Optimization to see if that helps. Is anyone else having these problems?

    I had issues when I first set my phone up. I did a factory reset and it resolved the issue.

    I turned off stamina mode and wifi calling and made sure that wifi was "always on". Havn't had any issues since.

    My S4 have similiar issues. TMobile said for wifi calling to work you need a strong wifi/internet connection and requires passing of a certificate. My wifi at my previous job blocked something the wifi calling needed so I was out of luck there. My house I'm generally fine but hotels seem to be hit or miss with wifi calling.

    Stamina mode creates to much havoc I just leave it off. Kills gps, networking to media servers, find phone is useless if you lose it.
