Hello, I'm having issues with my Samsung Galaxy S3 pre-installed messenger app locking up and not responding. I've suspected the imolji keyboard app so I uninstalled that. Still had problems. I upped the number of multi-media messages allowed to 50. I've upped the number of text messages allowed per text to 300. I've deleted as many unimportant text messages as possible. I'm down to 103. I've gone to my settings and cleared cache and data. I've even disabled it/forced closed it, restarted, removed battery. I'm at my wits end. I've started to use the Hangouts app but that it's also giving me issues. Please help. Thank you!
