With iOS it starts with the very first interaction - swiping to unlock. I can't disable it. Android and Windows both let me disable this. I just want `instant on` for certain devices (like 8 inch tablets) that I don't generally carry around in my pocket. But no. The closest I can get with iOS is enabling "Touch ID to unlock" which doesn't work sporadically and has bad timing.
The main thing I do on my tablet is web browsing, but web browsing sucks on iOS compared to browsing on my Dell Venue Pro 8 with full Chrome and all the extensions that I want.
I really wish that I could get into using mobile apps, but they'll never replace the web for me and I just can't deal with the 2nd rate web browsing in iOS which is directly caused by Apple's policies.
