It is possible that a quote mark is an invalid character for SMS. That may be why quotation marks are automatically replaced by an apostrophe.
Additional Note: I noticed you nearly simultaneously posted about 6 questions including 3 accidental reposts for a total of 9 posts in a surge in a very short period! (I've merged the duplicates to save you time, by the way) Including about 5 questions almost simultaneously in the same topic. Wow. To make things easier in the future, if you have a sudden need to post many questions simultaneously, I suggest grouping a small number of multiple questions into a single post, such as 3 posts of 3 questions rather than 9 separate posts as an example (i.e. categorize multiple questions together in a single post: Such as browser-related questions versus messaging/email/sms/folder related questions). That makes it easier for people to reply to the post.
