My Galaxy Nexus (Verizon) is giving me a ton of trouble. Even after a factory reset.

I got the phone back on launch day and since January it has given me a lot of issues.

I always have less service than every one of my friends who have Verizon (one even has the Nexus).

My 4G will stop working and take almost 10 minutes to switch to 3G and then it won't go back to 4G unless it switch it to CDMA-only and then back.

Sometimes my service will hang on the Messenger app and I can't send any texts until I exit the app.

Can someone tell me if I have a bad phone or if these are just Galaxy Nexus LTE issues?
