I noticed, already in 188.8.131.52 version, that auto-capitalization (needed) is ok in the first 2-3 sentences, but then fails and doesn't act properly, leaving lowercase letters after a fullstop or a question mark or two or three points ".." "..." (i.e.).
Example: Sentence1. Sentence2.. Sentence3.. sentence4! sentence5
Not solved in 184.108.40.206
EDIT 2016-12: not yet solved in 2.0.5
EDIT 2017-04: not yet solved in 2.1.0 (Android CL), failed once only in SMS
