I've been having serious lag issues with the messaging app for about the past week. If sending multiple texts in the same thread, there's about a 5-10 second lag before the first message starts to send, then the keyboard freezes up for a good 30 seconds. I at first thought it may be the keyboard I'm using (Jelly Bean) so I checked for updates, cleared the cache, nothing. Even went as far to clear all data from the app. Then I cleared the messaging cache, still nothing. Did a bit of googling, someone recommended clearing the system cache, did that too. I found that pulling the battery for 5-10 minutes helped, but only for a few minutes. Does anyone have any idea why I'm experiencing such a lag/have any other ideas? I still think it has something to do with the messaging app itself, since using the stock Samsung keyboard produced the same issue and there's no issue when using facebook, firefox, etc.
