Bro, try this.. Select message or keyboard when you start typing click on 3 dots above numbers at the right side and check if clipboard is there or not..
Ok, do one more thing, just press while typing, here you will find 2 options 1) paste and 2) clipboard..
If your phone has this, it's usually accessed by long-pressing the key to the left of the space bar, then tapping the clipboard icon (assuming you're using the Samsung Keyboard). And, if your device is not having this feature, then you have to download clipboard manager, to solve this issue..
