^JanerowenaHave you checked whether there is a second page of symbols on your tablet? That is where the square brackets are on my Samsung. Sorry if I am insulting your intelligence! grin
How did you do the sad on your post then?^
I did it manually. Just using normal symbols. I was away on holiday, but came back today so can use square brackets again now! I love my tablet but now feel deprived of a second page of symbols!
Both of the above are very applicable in this house!
