Annoying!

Seriously google! You guys are great with everything but why are you guys slacking on this app! Text message history randomly gets deleted. New thread randomly starts then goes back to old thread...this gets confusing when talking to multiple people. Sent messages dont always appear! Caller numbers not always recorded (missed call from "unknown"). Very frustrating!!! Please fix these. These are basic sms/caller history concepts, not anything fancy..
