Re: texting a reply.
Recently I can't scroll up to see messages above as I type reply.
The virtual keyboard covers the message being composed.
Therefore I can't see if my progress, mistakes etc until I touch the down arrow.
Same trouble with keyboards: always blocking the veiw,its like sitting behind a horse, the view is always the same no matter where the wagon goes!
Download Gboard if you have Google. Check main settings first. You may already have it. If not it's time to go to Googleplay or Apple store. Type in apps " keyboard" and you'll get more than you need. Some are free, some not. Be careful
