So I updated to iOS 10.1.1 last week on my iPhone 6 as the phone kept bugging me daily to update. I typically don't update iOS if it is stable. What a freaking mistake.
The phone is now locking up regularly, certain apps are crashing including super basic ones like the frickin calculator FFS! I had it drop off the cellular network, the touch ID doesn't work worth a shit and I really don't care for the new features so far.
Reading online there are 20+ common issues with this iOS and this has to be one of the worst releases ever! I held off upgrading so I can't down grade to an older version of the iOS as they are no longer signed by Apple.
If they don't fix this BS in the next update, I'm going Android and I have had iPhone's since the original was released.
