My Razr MAXX HD will not send pictures while connected to wifi. is this a settings problem?
No, the phone is operating normally. Picture texts won't send/receive over wi-fi, they require a mobile data connection.
If you have both wi-fi and mobile data turned on, the phone should switch as needed. However, for some phones, depending on radio signal strength, you may have to turn wi-fi off for the picture texts to send/receive.
