I used to have a rooted Nexus 6 (Android 6.something, sorry don't remember exactly, 32gb version bought from Verizon) which worked perfectly with Google's Project Fi. I had to replace the phone, and I replaced it with a 64gb Nexus 6 I bought off Amazon (currently stock rooted, running Android 6.0.1 build MOB31T). This phone does not work correctly with Fi; whenever it tries to switch to T-Mobile, it tries for 10-20 mins (and I have no signal during that time), and then eventually it will switch back to Sprint, which is what it is usually on. The same thing happens if I try to switch to T-Mobile manually. I've been getting "help" from Fi support for 3 months now. They can't figure out the problem and they are now saying they can't support a rooted phone. So as my last resort, I'm seeing if anyone here has had such an issue, or may know what the problem is. Thanks so much!
