Hi, I am thinking of upgrading my iPad Air 1 from iOS 7 to iOS 10 for the following reasons: 1. One of the games I want to play is available in iOS 9 onwards. I won't be surprised if more games I am playing now will have such restrictions. 2. I am currently investigating lag issues when using the iPad with a Lightning to HDMI adapter. I understand that the adapter has its own FW but it can get updates from the host device depending on what version of iOS it has. I want to see if upgrading will help 3. I am seeing strange crashes in some of my apps, especially Chrome. I have an iPhone 5 on iOS 9 that still gets updates; idea is to see if such updates help. So far, the potential issues I see is that it will be significantly harder to back up or restore apps due to the App Slicing mechanism. I will need to test iMazing seeing that it is marketed as the only solution in the market, but has anyone here have any experience with that? Note that I am also expecting a new 12.9 inch iPad too, but it will all depend on how long Apple will take to release the new one (no, I don't like how the current 12.9 inch iPad does not have the features of the 9.7 inch iPad Pro) I hope to hear from you all soon about all these and whether is it a bad idea to upgrade iOS or not, thanks!
