Awaiting feedback Problems with replying on Samsung Mobile

I realise that users often report problems that don't exist, but this is a trusted member of my forum saying he has problem replying on a samsung tablet.

He says

Also when typing in the reply box on my Samsung tablet I cant see what im typing. Every time I scroll down to check it and then start typing again it goes to the top of the page meaning it takes ages to type a reply or post
