Some useful small apps on iOS 9

If you have experienced it on iOS 9, users will notice some interesting new features like Siri smarter or new Maps. However, just like the previous iOS versions, Apple also lurks in many other features that not everyone knows.

Wi-Fi Assist

Wi-Fi Assist is enabled by default ( users can turn it off ). It allows users to automatically switch to using a mobile network connection ( 3G / 4G ) when Wi-Fi waves are weak to avoid interrupting the user's task.

To access this feature, users select Settings > Cellular and scroll down to the end of the installation.

Smart calendar application

The calendar app (calendar) on iOS 9 is much more useful than before. It can detect user scheduled events, flight information, or home bookings in the incoming mail section (on the Mail app) and automatically book an appointment.

Select multiple photos at once

Surprisingly, this is the first time users can choose multiple photos at once on the iOS's Photo app. After pressing the "select" button, users need to hold and drag to select multiple photos.

Arrange notifications

On iOS 9, users have the right to arrange their notification bar. You can choose to notify each application by group or manual to choose which notifications to receive from the application first. For example, you can choose to always receive notifications from Facebook and Mail on the top of the notification bar.

Leave a message for missed FaceTime call

Calling via Facetime is a feature that iOS users use quite a lot. With iOS 9, when it is impossible to connect to someone via FaceTime, the app provides more "leave a message" option.

Navigate between applications

On iOS 9, users can easily back up the recently opened application. When switching to a new application (among iOS's available apps) like Safari, Mail or app Store, iOS provides a small navigation bar in the upper left corner of the screen to return to the nearest application.

Having fun!
