The recent launching of Apple's iPhone 6S and iPhone 6S Plus has also introduced their latest OS update, which is the iOS 9. 

According to Neuro Gadget, the iOS 9 brought several updates including the 3D Touch Technology, which has been trending on the iPhone line. DropBox, Instagram and Facebook have previously declared their support for the said feature, and, now, WhatsApp 2.12.9 is joining them. 

WhatsApp 2.12.9 can now be downloaded from the Apple iTunes Stores with added minor updates aside from the 3D Touch Feature. Some of the updates include the use of Peek and Pop that stores location, videos and link as well as contact cards from chats.

The new WhatsApp 2.12.9 update is currently available on the latest iPhone 6S and iPhone 6S Plus. What's also interesting about it is its ability to support languages that are physically written from right to left like Arabic. 

As stated by Neuro Gadget, the iOS 9 is now on a stable phase, which means that consumers can now download the said app using the iTunes Store. 

TechTimes added some more information about the 3D application, which gives consumers easier access to some vital UI elements and other important shortcuts within the phone's apps.

Consumers who wish to get the latest WhatsApp version must remember to download the latest on Apple's OS in order to successfully use it. WhatsApp has also improved other features on their app but has chosen not to disclose them all.  Neuro Gadget, however, featured some of the bugs and fixes WhatsApp was able to update, including viewing of videos from older iOS versions. All of the new features would be experienced on the iOS 9. However, some consumers who have tried the iOS 9.1 beta, have also claimed that they have used the Quick Reply button.

Starred messages were also introduced by the developer wherein a user can press and hold selected messages. After pressing and holding a message, it will be marked with a star. This means that accessibility will be easier the next time you wish to retrieve the said message again. 

Considering what the whole OS will change and develop from your current phones, the mentioned updates are not bad. Check out for future updates in case you don't have time to explore your iPhone 6S and iPhone 6S Plus.
