I use my iPad to browse the web because it is always on standby. I pick it up show my fingerprint and 5 secs later I'm on. The iPad file system is a mystery and apart from better image resolution and 'facetime' thats about it for me. The 'half pic' problem on my iPad is rare and my 'fiddle' with it last night was a long press on the button to shut off and a long press to restart ... it's been ok since ... so it is an iOS bug.
I use Windows most of the time as do 99% of forum members, so we never see the problem. I have the Edge and Chrome browsers in my iPad but they are only 'wrappers' around Safari, Apple won't allow a 'stand alone' browser.
