I have no keyboard to answer the question in android 8.0

Question

technical difficulties

Answer 1

It doesn't show up if you click the text field?

Answer 2

Try Hacker's Keyboard if you need access to extra characters like {}[]\/<> etc. It's easy but a little slow compared to Unexpected Keyboard which is the ultimate keyboard: tough to learn but super fast _if_ you can master it.
Put like this: Hacker's = blaster, Unexpected = light sabre. Both are small downloads. If you need help installing, ask. Just @ me, no DMs/PMs please.
