I use messagease keyboard. It looks like this and it is awesome. It's the only mobile keyboard I can stand.
@Pookleblinky ok, I just installed. I'm now trying it. I'm slow but I'm making fewer mistakes. Why do you prefer it?
@pesterhazy it makes sense, minimizes effort, can be used with poor fine motor control, is easily adapted to any alphabet or ~syllabary from Arabic to Hangul to Hiragana to Zhuyin, is extremely customizable, and is utterly inscrutable to people who may want to use my phone
@Pookleblinky Poor motor control? I guess that describes me, given my problems with default android
@pesterhazy long-press on the hand, enter settings, keyboard & language. There's one designed for German letter frequency, etc
