Big Old Keyboard

Big Old Keyboard is, as its name indicates, a large, old-school keypad for Android devices. It works like the keyboards on older cellphones that had no touchscreens, when all the buttons were still concentrated in a small space.

Once you download and install Big Old Keyboard, you'll have to select it as your default. Go to your system settings, and in the 'personal' section click on 'Language & Keyboard'. Then just tick the box and select Big Old Keyboard as your default. This last step is very important: besides checking the box, you also have to choose it as the default (otherwise it will be the Google one).

Once installed and set up, you can start using Big Old Keyboard and enjoy its small advantages: buttons large enough for almost any user to use with no problem. The button in the lower left corner will also allow you to rotate between three different keyboard formats. And all this in an app that takes up just 34 kilobytes.
