I bought a very expensive phone that was unable to launch apps (50% of the time, when it did, it took several seconds) and unable to make calls (the receiving end would be mute and would not hear what I was saying).
The phone was bought on an official apple store and had one day of use. Problems persisted for over a week. Tried all the possible solutions. The only one that worked was downgrading to 10.
