My Droid Razr Maxx was updated this morning and right away found a couple of problems. First, although I was sitting next to my wireless router, the signal display indicated a really weak signal. This seemed to clear up after a reboot and an on-off-on cycle of the wifi on the phone.
The second problem was that, with the wifi off, I had no data signal. None. The phone worked but no 1x/3G/4G. I traced that problem to the phone configuration. Somehow the update turned off Mobile network data access. (Menu -> System Settings -> Wireless Netwroks -> More... -> Mobile networks -> Enable data access over mobile networks)
Seems like a dumb thing for the update to do.
I also noticed that the Network mode under SETTINGS | MORE | MOBILE NETWORKS was changed back to GLOBAL, after I had changed it to LTE / CDMA before.
After the update to my Razr Maxx I found that where I had one contact, I now have multiple versions of the same contact. Verizon tech support admitted that this is a known bug and told me I have to manually rejoin all the seperated contacts! Are you kidding me - I have hundreds of contacts and that could take days! I encourage others to voice their dissatisfaction at senior levels at Verizon Wireless to get some action taken. I'm a long time customer, but if they can't find a solution then come this fall when my contract expires it's time to shop.
Put all of your contacts in one place, Gmail contacts. Gmail will only sync one copy and is an excellent way to restore contacts after a factory reset. If you have contacts in Gmail, Verizon Backup Assistant, Facemail, etc. then you will probably get multiple copies. Ditch Backup Assistant ASAP if you have it activated.
Make sure all of your contacts are in Gmail Contacts, erase all contacts from your phone (clear data in Settings > Apps > All > Contacts Storage), and resync with Gmail Contacts.
