ONLY FOR SAMMY ROMS
This is my little contribution to you all... well i will try.
I use this code so that i receive the MMS automatically on my S3 without manually turning on the mobile data. Don´t know if with you is the same, but with me i need to turn it on.
So let´s begin:
With root explorer or other, go to /system/csc and edit the file with the name features.xml (on JB 4.1 Roms the file is others.xml)
Before the last two lines
<CscFeature_RIL_ForceConnectMMS>true</CscFeature_RIL_ForceConnectMMS> </FeatureSet> </SamsungMobileFeauture>
It works just fine to me, i use this mod every time and really hope to help you guys.
I learned this mod on a portuguese android forum: http://www.androidpt.com/index.php?/...ticamente-mms/
So i think the credits goes to that member.
