I have had this phone for a while and its a superb phone. Probably the sole reason why I still have it to date.
But there's one small issue that really pisses me off.
Every once in a while, while I am typing, the last word keyed in will just disappear yet I have not deleted it! Also, I noted that the clipboard randomly loses stuff I have copied. Is there anyone experiencing this too? How can I fix it?

Also, is there anyway to get rid of the keyboard options in the notification tray without root?

Use GBoard from the play store. It is the best keyboard you will ever use.

I use the Swype keyboard + Dragon, can not find for themselves, something better..

you can also use swype with Gboard
