Have you installed the public beta that was just released yesterday?
I installed the iOS 9 public beta when it was released & it worked perfectly fine so I updated to 10 hoping it would be the same and it seems to be so far
I LOVE the new iMessage features (I just need more people to use them with )
I'm on developer Beta 2. Now let me leave before people start bitching about it being "too buggy" and whatever else y'all like to make up problems about.
Yes, I love it, but it kept trying to change my words to stuff and I didn't want to turn off autocorrect because it helps sometimes. Plus it was a bit lagging on my 5C (which isn't too surprising). I'd recommend it if you have a 5S and up.
I downloaded it a couple of weeks ago when the first beta came out and I really enjoyed it. It made my phone kind of slow and a lot of my apps were glitchy, so I just went back to 9. I can't wait for the final version - it slays.
I had the first developer beta and it messed my phone up so I downgraded back to iOS 9. Some of the bugs were still present even then so I had to wipe my phone
