So I had my nexus 4 for like a week.....

Honestly I love it and all my friends do too but I had some problems with it. First there's is not much customization on it such as adding screens and I hate having to go to the Widgets menu to put it on my screen. Second I had some problem with my app freezing but what I really can't understand why they didn't doing anything new with the stock messaging app? I was out with my friends last night and I couldn't send a group picture messages out. Instead I had to send it out one by one. I don't know if it was just my service or the application. Can you help find a good messaging app?
