1/ Search tabs in Safari — The iOS 10 version of Safari lets you open up an unlimited number of tabs while you’re browsing. That does bring its own problems though, including not being able to keep track of your browsing, and that’s where tab search comes in.
Rotate your device into landscape mode (it will not work in portrait) then tap the tabs button. A new search box appears in the top left corner. (You may have to swipe the screen downwards and ‘bounce’ it to make the icons appear).
Enter your search terms and Safari filters out the tabs as you go. Bear in mind you’re only searching through the titles of the tabs and not the actual web pages. When you’ve found what you’re looking for, tap to open the tab.
2/ Set your preferred contacts — Apple finally lets you set the default communication method for each category (call, message, video, mail): press and hold on the relevant blue iconic the Contacts app. This will initiate a call or a message or whatever, so just be ready to cancel it. But iOS 10 keeps this as the default for next time.
Confusingly, this doesn’t change the default communication method if your contact is already listed as a ‘favorite’. Pick ‘Add to Favorites’ to set your preferred option, then head to the Favorites screen itself to ensure it’s the only choice for that contact.
These listed favourite options are the ones Siri uses when you ask it to initiate a communication with someone.
3/ Edit contacts in-line in Mail — You have long been able to tap a contact’s name in email headers to view their details. In iOS 10, you can now edit them right there, as long as they’re listed in Contacts. If they aren’t, you can use the typical add/update contact option, then edit in-line.
4/ Answer Messages from the Lock screen, or not — Under iOS 10, we can now reply to messages without unlocking our devices, which is really convenient. The text that shows up shows ‘Press for more’ on iPhone 6s and 7, and ‘Slide for more’ on earlier iPhones. You can turn this feature off if you’re worried about others replying to your messages from your iPhone while it’s on lock – the option is under Settings > Touch ID & Passcode > Allow Access When Locked, and it’s labeled ‘Reply with Message.’ If you turn that off, pressing or sliding on an incoming message will not work.
5/ Reduce Motion affects Message effects — An unintended side effect of the Reduce Motion option in Settings>General>Accessibility is that it disables all Screen and Bubble Effects in the new Messages app. Users with Reduce Motion enabled cannot access the Effects interface, and no Effects associated with incoming messages will be displayed.
To check your own iOS device, head to Settings>General>Accessibility. In the Vision section is an option labeled Reduce Motion. Tap it to reveal the option’s toggle and set your desired preference to disable or enable it. So if you long ago enabled the Reduce Motion option and are now wondering why you can’t see these new Message Effects, this is probably why.
