"Samsung Gear S2" has proven itself worthy of praises, both in terms of controls and design. Its alternative software approach has also received good response from reviewers. According to GSMarena, the "Samsung Gear S2" may look like a potentially failing product on the surface, but it has actually used a pretty clever strategy, because as per the tech site's comments, Samsung definitely got lots of things right with the "Samsung Gear S2".
But still, despite the good response the "Samsung Gear S2" has received, no product remains flawless. And just like most wearables, the "Samsung Gear S2" also has some issues to face. It's undeniable that one of the biggest problems faced by the wearable is its relatively lacking software, at least when compared to Android Wear. However, most developers have developed a liking to the OS which leads to the bridging of the strong app gap that the OS has. One good addition to the "Samsung Gear S2" is the QWERTY keyboard.
Called the Agile Keyboard, this app costs $0.90 and it is a Samsung styled keyboard complete with T9 prediction. The good thing about this is that the Tizen OS of the wearable also allows third party apps to be easily implemented. The said app is easily switched on through the watch, all thanks to Tizen's developer friendly design.
Furthermore, to further maximize your IM experience on your wearable, another app is on the process of making it into the "Samsung Gear S2". This shall solve the issue that is common to Android Wear and Tizen wearables, specifically the lack of ability to reply to instant messages while on the notifs center. The problem is that you can only send a single reply to someone's message but you cannot proceed to a conversation after that. The upcoming app will act as your message hub that allows for active chat management, allowing you to chat with your friends as you please. It will support your usual messenging apps such as Facebook Messenger, Hangout, KakaoTalk, WhatsApp, Viber, Skype, and probably many more.
