In addition to the Galaxy S9 duo, Samsung apparently brought another new mobile phone in the event Mobile World Congress 2018. The phone is tough because it is intended for police, military and fire brigade.
Perhaps because it will not be sold freely, South Korean vendors did not give a name on this phone. They just call PS-LTE. PS itself is a Public Service.
When kidnapped this phone has the code SM-G888. This code itself had leaked not long ago. Funny thing is that many think it is a folding phone that will be issued Samsung. It turned out wrong allegations, SM-G88 appear like most smartphones on the market.

But Samsung equip this mobile body with a special coating. So the design looks sturdy and claimed to withstand all the impact. Made based on Galaxy S7, this phone also pocketed IP67 certificate which means dust and waterproof.
A number of special keys were given this phone. At the top of the body there is a button for emergencies. Then on the left side of the body there is a large red button that functions for walkie talkie.
On the back of this phone does not have a fingerprint sensor. Instead there are three LED Flash. It is intended to provide plenty of light in case of emergency or else perform other operations. In order to survive longer, Samsung immersed a battery with a capacity of 4500 mAh.
Samsung did not mention the price of this phone when it was released. Reasonable because considering the PS LTE is not sold to the public.
