The basic app is samsung keyboard guys but samsung has it's own way to make u hate them or regret on buying samsung.In galaxy N9 series the samsung keyboard app gives u emoji predictions and even GIF but in my galaxy M30 Samsung keyboard don't give ...
Samsung is that company who look shiny from outside but it's hollow from inside and don't listen to u there are no of apps which can't be installed in m30 like good lock sound assistant etc
There is an official app s secure of Samsung, i dnt knw the availability in s series but it is available on galaxy store and u can lock with all the three option pin face and fingerprint
