Have you tried the iOS 11 beta version? If you did and you are already tired of bugs, then you can downgrade your device back to iOS 10. All you need to do is to follow some quick steps and your problems will be over.
Some users who tried the new iOS version have had major issues and were not satisfied with Apple’s iOS 11 public beta. Some of the dissatisfaction is due to many bugs they have encountered, the quality of the animations, the quality of the graphic elements and the fact that applications seldom crash.
For those of you who want to use the previous version, the iOS 10.3.3, these are the steps you need to make:
First, you need to go to the Apple Beta Software Program page and download the image of iOS 10.3.3 which matches your device (the same one you used previously, before updating to the iOS 11 beta).
Secondly, download the IPSW file and be patient as it might take some time since it has some gigabytes in size.
Thirdly, you need to connect your iOS device to your computer and put your phone on the recovery mode. Now, if you own an iPhone 7 or iPhone 7 Plus, you need to press and hold the Sleep/Wake and the volume-down buttons. If you own other models of iPhones, you need to press and hold the Sleep/Wale and Home buttons.
Fourthly, you will be able to see an iTunes pop-up with the options of Restore and Update. You need to Shift-click (if you have a PC) or Option-click (if you have a Mac) on the Restore button and then you have to choose the file you have downloaded in step two and click Restore.
Finally, your device will reboot and it may take a while so be prepared to wait.
