So I've have had a galaxy s4 since it came out and it's on it's last leg. I just got the HTC One M8 and only have my contacts and music on there. Anyone know how to transfer the data from my old galaxy s4 to the new phone? The music was easy since it's on google play, but I can't figure out how to transfer text messages, apps, voicemails, etc. Any help would be awesome.
