SMS Help

[Oh Joseph]

Hi, to start I just got a month ago the lg optimus G. Works like a well oiled machine but the oem sms app does not really have all the features I like to use . Taking that in consideration I decide to go with one from the play store like Go sms pro,Chump and Zlango (try them all already). The problem is that all them sometimes send the message to the wrong contact specially if it is a long message or while downloading an MMS. I do not know if it is a failure of ICS or if it is the phone itself. I have use in the pass go sms pro in my old Atrix with Ginger bread, no failure as the one mentioned above with my new phone. Please advice. thanks
