For auto correction the keyboard sends a map of what keys are near what other keys to the prediction engine. This map is supposed to be based on lowercase keycodes. But sometime recently (presumably as a result of the recent keyboard all-uppercase change) it has changed and now sometimes it sends an uppercase-based map. When we have a bad nearby key map we get corrections that do not take nearby keys into account. When we have a valid key map, we get better suggestions. To reproduce this bug open the UI tests app, click on keyboard tests and type 'ch' into a field. It should suggest 'cha'. Now tap on another field (or lock the phone and then return to the app) and type 'ch' again. This time you get VH. (I don't know what that is an abbreviation for, but it is the correct suggestion. Other examples include s->a when the keyboard map is correct and s->s when it is not.

Actually, this has to do with auto-capitalization. In text areas, we autocapitalize and are getting uppercase letters in the nearby keys. In textfields by default we do not auto capitalized and don't have this bug. In a text area after if you're in lowercase and sleep the screen and wake it back up you'll get a new nearby keys data, and it will work.

On the latest master build I am still getting different nearby key data after causing the device to sleep and then returning. Just as in the decription, I entered "Ch" and received "Cha" as a suggestion but after causing the device to sleep I received "VH" as a suggestion forthe same characters.
