Hi Tomas, Sorry to hear you are having difficulties with messaging. We would like to request some additional details for the issue you are describing. What carrier and model are you receiving the MMS from? What content are you receiving via MMS (multiple pictures, one picture, mix of content types, etc.)? We would also ask if you can provide your software version. Steps to check version linked here: LG Help: Product Support and Troubleshooting | LG USA ^SM
There is a widespread problem on every carrier with the KitKat update on G2, no one can send mms and have to use an app like FB or KIK to send pics. Hours on the phone with Verizon and LG conferenced said no fix planned!!!! WTF!!!
