On Three with an Xs. Took my case off earlier on while just around my house for a few phone calls.
One call i was on hold to a call centre so i put it on speakerphone while i waited, then when i actually got through to someone i went to pick up the phone and a few seconds later a call failure happened. Called back, was put on hold again so went into speakerphone mode again, then when i finally got connected i went to pick the phone up and got disconnected again.
Then, just a few minutes ago. I received a call from my sister and after a few seconds of holding it in my hand against my ear i got the call failure message appear and it cut out. Tried again several times and i kept cutting out after only a few seconds.
I put my phone case back on, and called my sister again. This time call didn't cut out after a few seconds, and everything was back to normal.
I've had the Xs for 2 weeks tomorrow and always had a case on it so never had any problems. This afternoon i was just trying it out case-less (but only around my house though) and started getting these problems.
Anyway, i have until tomorrow to return my Xs and cancel my new contract, so i'm just going to go ahead and return it.
There's something not quite right with it without a case on it, and even though i tend to always use a case anyway, i don't want a gimped phone that only works if a certain criteria is met.
I might just wait for the Xr, or a i may rinse another year out of my 6s Plus.
