Ever since the software update my son's LG G3 is sporaddically not receiving texts from iPhone users. His phone number has never been registered with an Apple ID so that is not the issue. His G3 will ring with the alert but when he opens messages the text is not there.
We have tried restarting the phone several times. This seems to help he will then receive the last missed text that was sent but then will continue to not receive new messages. This problem appears to be limited to iPhone users.
