I purchased the samsung galaxy s4 2 weeks ago still learning so much on this phone but am getting very discouraged after trying to send mms messages, & video's. The wheel just keeps spinning on the mms messages and after seems like forever it says message not sent. I have done everything that people have posted on here I even tried the handsent app and it not let me either.For the videos they just wont send at all. Please fix this issue with update or something. I went from an iphone to this phone I not want to regret it. If you have any solutions please help.
