This is a problem i've been having since i got this phone, but as i found a workaround i lived with it for a while, bet enough is enough.
Whenever i send a picture message to someone after a few seconds the message pops up as "failed". to get the picture to send, i have to delete any existing conversation with the recipient(s) and then resend a brand new message with the picture and it works no problem, this however does become an issue on ongoing group messages or if there is info in the conversation that is important that i need to keep.
any ideas as to what can be causing these messages to fail? I have reset my phone, but the problem was still there. any ideas or help would be appreciated!
