Of course the Plus-sized iPhones are really great but if you don't want to spend time to reach to the top of the display to tap on a notification banner when friend sent you a message then you can open notifications with 3D Touch in iOS 9. If you have jailbroken device you can install new Cydia release called NotificationPop that takes advantage of 3D Touch feature to quickly get to notifications. Here is how everything works.
How To Launch Notifications With 3D Touch Gesture On iOS 9 iPhone
With NotificationPop, whenever a notification banner appears on your screen, you can use a 3D Touch gesture anywhere on the screen to launch the notification. Essentially what happens is the 3D Touch gesture simulates a tap on the banner.
So to install this tweak you should head over to Cydia’s BigBoss repository and grab NotificationPop tweak absolutely for free. The tweak works with any jailbroken iPhone that supports 3D Touch feature.
Once the tweak is installed you can start to use it as NotificationPop doesn’t brings any options to configure.
So the next time you will get any notification you can use the 3D touch gesture to quickly view it. If it’s a Twitter notification, it takes you right to the Twitter app or if it’s a Facebook notification, it takes you right to the Facebook app, etc.
As you can apply the 3D Touch gesture anywhere on the screen, even from the bottom, this tweak makes life so much easier for users with smaller hands or for those who have the Plus-sized iPhones and struggle to use it one-handed.
Personally I find the NotificationPop tweak really useful as it offers extremely quick way to open notifications with 3D Touch in iOS 9 on may iPhone 6s Plus. So if I'll get the message notification then it takes me a second to get right to the conversation and view it.
