Fasten your seat belts, as the first problems with iOS 10 have already surfaced. A large number of users around the world including our post are reporting problems with the OTA update process (over-the-air, that is, by the device itself); according to them, the affected devices suffer a "Brick", that is, they lose all information and require that they connect the device to iTunes on a Mac or PC.
Connecting the iDevice to the computer, then, it is necessary to restore the device in order for it to function normally again. The problem seems to affect iPhones, iPads and iPod touch touch of all kinds and generations without distinction, although the models with the highest volume of problem reports are the 9.7-inch iPad Pro, iPhone SE and iPhone 6s.
Apple has already commented on the problem, stating that a small number of users were affected by the bug in the first hour of availability of the update, and all those affected must connect to iTunes to complete the update.

We experienced a small problem during the software update process, affecting a small number of users during their first hour of availability. The problem was quickly resolved and we apologize to these customers. We recommend that everyone affected connect their devices to iTunes to complete the update or contact AppleCare for assistance.
That is, according to Ma's words, the problem has already been solved and updating your OTA device is already safe again. Still, if you want to surround yourself with all the security, it's good to take the cobwebs out of iTunes and do the process for it without forgetting to make a good backup of all the important information beforehand, of course.
