I have just upgraded from a 5S to a 6S. I've noticed that on the spotlight search screen email previews are way too big. I swear I had more search results on the 5S screen despite it being much smaller. I have the Apple Wallet 'zoom' bug, so I wondered if this was a similar bug. I've checked the usual Dispaly and Accessability setting to see if I can make text smaller, but no joy.
