Hello all, I had teh iPhone 7 Jet Black for about a week now. Everything was running great until this morning when I updated to 10.0.0.2. Now my phone is going haywire. It seems the phone is constantly HOT when it's on, going through screens are laggy and most importantly I can hardly operate in the mail app. Freezes in mail app. I unplugged my iPhone at around 8AM with 100% battery, it's now 9.48 and i'm down to 23%. I dont 'know if it's the 10.0.0.2 upgrade which caused this or something else. Is anyone else having this problem?
