Text keypad has disappeared
A few weeks ago the text keypad on my Doro Liberto 820 Mini suddenly disappeared and was replaced by an icon of a microphone. The only way I can now send a "text" message is to speak into the phone, which isn't acceptable. I can no longer type in the text a character at a time. When I go to Settings, "Language and input", "Keyboard & input methods" it says the default is "Automatic - Google voice typing". There is no other option given. Is there any way of restoring text input other than a factory reset which I am reluctant to do for obvious reasons.
