Which keyboard to choose for android mobile?

Question

Android

Please advise a keyboard for a mobile Beeline Smart (huawei y320) with Android 4.2 and a 4-inch screen.
The standard keyboard that comes with the delivery does not suit, because:
1) I have big fingers and often miss;
2) Infuriates the location of the microphone button, forever instead of a space or 'c' I get on it
3) Infuriates the location of the back button, trying to press Enter I get to the back.
Therefore, the requirements for the new clave are:
1) Adaptability for thumbs
2) A Swype-like solution is possible
3) The mute and microphone buttons are in other places or so that it is possible to reconfigure their location

Answer 1

Google Keyboard

Personally, I prefer Smart, because can be easily customized

Answer 3

I liked the keyboard from Yandex.Kit :) You just need to cut it out of the assembly...
